Product Review–Western Digital WDTV Live network media adaptor

Introduction

I am reviewing the Western Digital WDTV Live network media adaptor. This is and adaptor that connects to an external display like a TV, monitor or projector and/or an external amplifier in order to play media files held on a local storage device like a USB memory key or via a small network.

The device itself

The unit's remote control

It is a small device about the size of two packets of cigarettes stacked on top of each other and is powered using a power adaptor. Users operate it with a very small remote control that has the main transport functions and a D-pad for navigating around the user interface.

Setup

How this connects to your TV

The device connects to the TV using an AV cable that plugs in to a four-conductor 3.5mm jack on the back of the unit. There is another 3.5mm four-conductor jack for connecting to the component-video connections on a suitably-equipped display device with a separate patch cable. Of course, this unit can be connected to HDMI-equipped display devices like most plasma and LCD TVs; and it has an optical SPDIF socket for connection to equipment with an optical digital input like most surround receivers.

Sadly, this device doesn’t support connection to display devices that use RGB inputs in any form. This may affect those of us who want the best out of monitors or projectors that use such connectors like most SCART-equipped European TVs, business-focused “data projectors”, classic “3-gun” projectors or professional-grade video displays. You may get around this by connecting the device to the display via one of the “HDFury” HDMI-RGB adaptors

It has the ability to play media that is held on USB-attached storage devices like memory keys or USB hard drives. This can be useful for playing media that you have held on one of these devices.

As for video codecs and file types, it can natively handle most audio and video file types including the DivX and Matroska MKV family of file and codec types.

Network setup

The WDTV Live HD can be connected directly to an Ethernet network or HomePlug AV network with the appropriate “homeplug” bridge device, But it is one of these “wireless-ready” devices that connects to a Wi-Fi network using an optional Wi-Fi dongle available from Western Digital or through one of their retailers.

Use

This can work with any display device including older TVs

The user interface is a “full-screen” one which works to the edge of the screen. This may be of concern with those of us who have hooked the WDTV Live up to an older CRT-based TV set that has the orthodox curved screen edges. As well, the logos for the Internet services are rendered in a dull manner and could benefit from “true-colour” display with a highlight around the currently-selected service.

Of course, there is a screen-saver function which can be overridden for displays that aren’t affected by long-time display of images or set to appear after a time between 5 minutes to 15 minutes. Here, it just shows the WD logo; but could show now-playing information during audio playback.

Online services

The Facebook service has the expected functions like viewing one’s own news feed, contributing to a Status Update or writing one’s Status Update as well as the ability to view one’s Photo Albums or a Friend’s Photo Albums. All text entry is based on “pick-n-choose” methods and the pictures do come up properly on the full screen.

I have tested the YouTube service with this device and have used it to play some videos including the service’s “poster child” video which is the “Keyboard Cat” video. The user interface is what would be expected for a 10’ interface and the users would be required to use the “pick-n-choose” method for any text entry like account login or video searching.

The “Tune In” Internet-radio function works properly for Internet radio access and allows the Internet radio stream to play in the background while you navigate the menus. During the day, It had performed well on quality-of-service when streaming Internet radio; but like all Internet services, this will depend on how congested the connection is.

UPnP AV / DLNA media access

The UPnP AV / DLNA functionality on the WDTV Live works properly when you use the remote control to call up the content on your UPnP AV / DLNA Media Server. In previous firmwares, this media player had problems when playing out media under the control of a UPnP AV Control Point like Windows 7 or TwonkyManager. Here, it would play only one item at a time and require the user to advance the media to the next item using the remote control or the Control Point.

Now, units that have firmware newer than version 1.65 can play multi-item playlists and slideshows without needing to be “pushed on”. There is still a problem with this function, especially with image slideshows and video playlists where the unit will show its menu every time a new image or video is loaded up before it plays that image. This could be improved with “read-ahead” buffering for subsequent media items.

Limitations and Points Of Improvement

I would like to see the user-interface improved in various ways, such as use of brighter colours or full-colour logos for the Internet services.  The screen-saver could also support “service-driven” behaviour like showing now-playing information for audio sources.

As well, this device could benefit from integration with local online-video services like the local “catch-up TV / video-on-demand” services offered by the local TV stations. Of course, I would like to see an improvement on the media changeover behaviour when the device is used as a UPnP AV / DLNA MediaRenderer under the control of an external control point.

This device’s form factor could be taken further with an integrated digital-TV tuner for implementation as a digital-TV set-top box that could have online and network media access as well as digital-TV access.

Conclusion

I would recommend the Western Digital WDTV Live or any of its successor models as a cost-effective device that can be useful for pressing a cheap or old TV, monitor or projector in to service as a network media playback device in the UPnP AV / DLNA Home Media Network.

DLNA now meets Pay-TV setups

New DLNA Interoperability Guidelines Will Turn Your TV Set-top Box into a Home Server | eHomeUpgrade

From the horse’s mouth

DLNA Press Release

My Comments

DLNA have released a set of interoperability guidelines for networked equipment that can play premium pay-TV content, whether live or recorded across the home network while keeping it secure. This is based on the DTCP-IP link protection protocols so as to protect the content from being re-streamed in an unauthorised manner.

AllVid and similar initiatives

These guidelines will lead to the acceleration of the “AllVid” initiative that has been put forward to the FCC by the likes of Sony and TiVo. This is a way of providing an open scenario so that people can use equipment they have bought with their pay-TV services in the US rather than having the TV just become a display for their set-top box leased from the cable company.

The idea behind tis concept is that there is a “gateway” device that connects to pay-TV broadcast services like cable, satellite or IPTV. This device connects to TVs, set-top boxes and PVRs via the home network using DLNA-specified technologies and is responsible for bridging the broadcast content to the home network as well as managing the access-control to the premium content on the pay-TV service.

If it receives broadcast content from terrestrial, cable or satellite services, it would use one or more RF tuners and circuitry to present the broadcast channels as network streams as well as authenticating and authorising the pay-TV content. On the other hand, an IPTV setup which connects to the home network would simply authenticate the content and present it across that home network.

It also will provide for situations where the user may change to a different pay-TV service that uses different technology or move to a different area that uses a different pay-TV service without losing their investment in their equipment.

OCAP-compliant “Tru2Way” cable-TV setups

The first main implementation would be cable-TV systems that are based on the OCAP-compliant “Tru2Way” platform. These will have a regular set-top box with separate security measures that can work across the different cable-TV setups. As well, they would be a DLNA server that works to these guidelines, providing the channel lineup that the customer has subscribed to as well as programmes recorded on this set-top box to the compliant TV equipment.

Of course, the main application with this could be to serve the content out to secondary TVs that are compliant to this standard or are connected to video peripherals that again are compliant. It could also lead to the main TV being connected to a “video server” set-top box

The main difference between these setups that one should know is the kind of “skin” that is expected on the user interface. The “AllVid” user interface is expected to have the viewing device’s branding like Sony’s XrossBar rather than the media-provider’s. Conversely the Tru2Way platform is meant to have support for the content provider’s or service provider’s “skin”. This also includes the creation of DVD-style menus and user interfaces along with the enablement of full interactive television apps like voting up that favourite dancer or singer on that talent-quest reality show.

Questions

Pay-Per-View services

A good question that hasn’t been answered so far is how this will enable the initial purchase of “pay-per-view” content. Most pay-TV operators run one or more pay-per-view content services, either in the form of one or more broadcasted events that is sold in this arrangement or a “movie-on-demand” or “virtual cinema” service with a few of the latest blockbuster movies shown across multiple channels.

The current problem is how can a user instantiate a pay-per-view content purchase in one of these setups using the TV’s remote control; and seeing it through so that the content is available and duly authorised. This includes allowing the account owner to place controls on what pay-per-view content can be purchased in their home.

What do customers look for in the new equipment they intend to purchase

Also, customers need to have something to look for when they purchase TV equipment so that they are sure that the equipment is compatible with DLNA’s premium-content requirements. This could include a “super-logo” that is exhibited on compliant equipment, with the equipment having to support the DTCP-IP functionality as part of this functionality set.

Retroactive upgrading of current equipment

The other factor that needs to be looked at is whether this DLNA premium-content-handling functionality can be brought to existing DLNA-compliant hardware such as the current crop of Sony and Samsung TVs through a firmware upgrade; or whether they would need to replace the existing hardware to gain this functionality.

This will be more important with TV sets as people who upgrade TVs will end up deploying their existing sets to other rooms of the house or to other locations.

Conclusion

At least the use of DLNA technology and the extension of broadcast-content-protection methods to the network could make it easier to allow flexible equipment setups in most mainstream viewing applications.

IPTV now being featured on mainstream TV media

Articles

Smart TVs (A Current Affair article) – NineMSN VIDEO

My Comments

From the recent “A Current Affair” broadcast on the Nine Network, it seems to me that the “Smart TV” or “Internet TV” concept is now ready for prime time.

What is this trend all about?

This is where functionality like access to IPTV channels, “catch-up” TV and video-on-demand is now being integrated in to most of the big-name TV sets that are to be sold at the likes of Harvey Norman. It will also include an “app-store” interface so that users can add functions to these sets in a similar way to how they add functions to a smartphone or tablet computer.

Some of the sets will come with an integrated hard disk which will provide PVR functionality. But what wasn’t mentioned was that most of the sets from the big brands, especially LG, Samsung and Sony, will support integration with the DLNA Home Media Network. This means that these sets could play content held on a computer or network-attached storage device that uses this standards-based technology.

Typically, these functions will be pitched at TVs targeted for the main viewing area i.e. the main lounge room or family room. But this kind of function may be added to existing sets through the use of some of the current-issue Blu-Ray players and network-media adaptors like the Sony SN-M1000P network media adaptor.

A few key questions that I have

“TV plus Apps” or IPTV and interactive-TV content?

There could be a fear that this could turn out as “TV plus apps” with the same old TV content plus some apps such as clients for the popular social networks, photo-sharing sites and YouTube-type sites thrown in.

But some providers are making ties with the various manufacturers to set up free and pay-TV front-ends through the IPTVs. Examples of this include Samsung establishing a tie with BigPond TV to provide direct access to that content or most of the manufacturers running ABC iView through their TV sets. It may also open up opportunities like video-on-demand or boutique content services. As well, once there is a level playing field for adding TV services, this could lead to the addition of extra TV content.

If there is a desire to provide new live or on-demand IPTV services, there needs to be support for adding the newer services to existing IPTV equipment. This could be achieved through an always-live app store on these sets. Similarly, existing broadcast content, both editorial and advertising, must be able to support links to apps and interactive front-ends that are accessible to the average viewer with one click of a particular button through the use of interactive-TV content-delivery standards.

This can include applications ranging from interactive games and competitions that are part of children’s TV through “play-along” quiz shows to polls run in conjunction with current-affairs shows which have the option for you to view “extended-version” interviews.

Equipment Useability

A key issue that I have raised in this site was the useability of services like the Social Web on this class of equipment. Typically, the “smart TV” concept prides itself on connection with social-network services like Twitter and Facebook; but there will be the desire to gain access to photo-sharing sites like Flickr and Picasa or gain full benefit from sites like YouTube. These can make use of “smart-TV” services more daunting for someone who doesn’t find themselves competent or isn’t experienced with technology.

An example of this was when I mentioned to a friend of mine about the Pixel Eyes app on the TiVo platform where they could view their Picasa albums through the lounge-room TV connected to the TiVo PVR. I mentioned that they would have to log in to their Google account using the “pick-pick” method of entering their credentials in order to view their pictures on this service and this idea frightened them off it.

The main problems is that different users will want to log in to this common terminal or, in the case of the Social Web, leave comments in relation to what they are viewing. Typically, this will require a fair bit of text entry and most remote controls won’t be fully engineered to cater to this requirement. The user will typically have to work a D-pad or wave a Wii-style “magic remote” around to pick letters from an onscreen keyboard and may have to switch between logical keyboards to use different character sets like numbers, different-case characters or punctuation. Try entering in a Facebook / Twitter / Google username and password that way or “knocking out” a Tweet that way.  As well, I have raised in that same article methods in which logging in to these services from devices like TVs and set-top boxes can be simplified and referenced how Facebook achieved a login experience suitable for these devices with their HP ePrint app. This includes being able to change the active user associated with a TV or set-top box to another user.

Similarly, I would look at issues like keyboard support for IPTVs. This is whether a TV comes with a QWERTY-enabled remote or not. The best method for add-on keyboard support would be to use Bluetooth HID connectivity so that a Bluetooth-based wireless keyboard can be used as a text-entry tool. Similarly, the ability for one to plug a standard USB computer keyboard in to the USB port usually reserved for USB memory keys and use this for text entry may make things easier. This would work well with those wireless-keyboard sets that plug in to the computer’s USB port.

A remote that doesn’t have a QWERTY keyboard but uses a numeric keypad for direct-channel-selection or parental-code-entry could use this keypad as an “SMS-style” text-entry interface, something which many nimble-fingered teenagers are used to. This would work better if it used the character-set-selection practices used on popular mobile phones.

Other methods that can be looked at include the use of smartphone apps as virtual remote controls like what Samsung has done for their Android smartphones. Here, a user could download an app to their Galaxy S phone and have this become the TV remote control. This could be extended to ideas like multi-control for interactive applications such as “own-account” operation for Social Web and similar applications with the TV screen becoming a “common monitor”.

What to consider when choosing or using your network-enabled TV

DLNA functionality

The TVs or set-top devices should support DLNA Media Player functionality at least, with preferable support for DLNA 1.5 Media Renderer functionality. Initially this would give you access to content held on your computer’s or network-attached-storage device’s hard disk.

The Media Renderer functionality can allow the TV to be controlled by a UPnP AV / DLNA control point such as TwonkyMobile, PlugPlayer or Andromote on your smartphone or tablet computer, or TwonkyManager on your netbook.  In the case of Blu-Ray players and set-top devices, you may even be able to play music from your network storage through your favourite stereo without the need to have the TV on to select the music

If the TV or set-top box offers integrated PVR functionality, look for DLNA Media Server compatibility because this may allow you to play recorded TV shows on other TVs in the house without them needing to be of the same brand.

It is also worth noting that some DLNA functions like DLNA server or Media Renderer may not be enabled by default even though the set has these functions. Here, you may have to go to the setup menus and look for “DLNA control”, “Media Server” or similar options and enable them to benefit fully from these functions.

For further information, it is also worth reading the DLNA Networked Media articles that I have written on this site.

Connecting the set to your home network

When you connect one of these TVs to your home network, I would suggest that you avoid using Wi-Fi wireless connectivity, especially if the TV or set-top box uses a dongle for this connectivity rather than integrated Wi-Fi connectivity. This is because of the fact the Wi-Fi network is radio-based and if anything is shifted slightly between the Wi-Fi router and the TV, you may have service-reliability issues.

Instead, I would recommend that you use a wired method such as Ethernet cable or a HomePlug AV powerline-network setup. The Ethernet-cable solution would work well if the router and TV are in the same room; you have wired your home for Ethernet or you can get away with snaking Ethernet wiring through windows. On the other hand, the HomePlug solution would work well for most users who don’t want to or can’t lay new wiring through their homes because this uses the house’s existing AC wiring.

In fact, if you are renovating or rewiring your home, it may be worth considering wiring the house for Ethernet and making sure you have an Ethernet connection in the main TV-viewing areas of the house. This may be achievable if you have an electrician who is competent or knows one who is competent with communications or data work doing the job.

Conclusion

This site will have regular coverage of home media network issues that will become of importance as we head down the the path towards online home entertainment.

Product Review–Rotel RCX-1500 Network CD receiver

Introduction

I am reviewing the Rotel RCX-1500 network CD receiver which is one of the first “big-set” hi-fi units that I have reviewed that can do proper Internet radio and benefit from the DLNA Home Media Network. Previously I have been reviewing Internet radios that are mainly “small-sets” which are table / clock radios or portables and are intended for use as secondary or auxiliary audio devices.

The product class

This unit is infact a CD receiver, a class of “single-piece multi-function” hi-fi music system which continues from where the music centres and casseivers (receivers with integrated cassette decks) of the 1970s and early 1980s left off. Here, some of these units were equipped with the functionality and quality of modest separate-unit hi-fi systems yet they offered this in a single box, which you could just hook up a pair of speakers to. The manufacture of high-sndard pieces of this class of equpment had diminished through the late 80s. This is although Bang & Olufsen were consistent in this field at a premium price and a few other manufacturers like Proton, Bose and Onkyo were releasing in to their model ranges  one or two receivers with integrated CD, tape or MiniDisc transports that weren’t just second-rate music systems.

Then there had been a slow but sure renaissance in this class of good-quality integrated-function hi-fi equipment as the trend for “downsized” living especially in “executive” city apartments became more intense. This is where most of the good hi-fi names ran with at least one CD receiver in their line-up that didn’t come with a set of substandard speakers and this Rotel RCX-1500 that I am reviewing is one such piece of equipment.

This unit was tested with a pair of Cabasse Antigua MT30 bookshelf speakers connected using premium audio cables. These speakers were also on loan from the distributor so I can review this unit properly. They are built using an orthodox two-way driver arrangement and use a bass-reflex enclosure and can work with amplifiers that have a minimum power output of 75 watts and maximum of 500 watts. As far I was concerned, these speakers worked very properly with all kinds of music and could yield a decent sound for their size.

The Rotel CD receiver

Functionality comments

Slot-load CD player

It is also worth knowing that this CD receiver has a pair of pre-out connections so one can connect it to a more powerful and better-sounding power amplifier or a pair of active speakers like an active subwoofer or some of the active speakers like B&O’s Beolab range or any of the Bose Powered Acoustimass speakers.

It can connect to your home network via Wi-Fi or Ethernet using supplied network-adaptor dongles. The Ethernet option can also allow it to be used with a HomePlug AV network segment using an appropriate “homeplug” adaptor and I would recommend this as a “no-new-wires” option for connect this CD receiver to the home network.

This functionality allows this CD receiver to provide Internet radio or work with a DLNA-compliant media server that is on your home network. The only limitation with this function is that it doesn’t work as a MediaRenderer which means that you have to select your network media using the Rotel CD receiver’s display.

The tuner is “up to the minute” with broadcast radio in Europe and Australia by supporting FM RDS as well as DAB+ radio. There are two antenna connections for both FM and DAB but you can choose to use the FM aerial for DAB. It came with two aerials – the typical “T-wire” for FM and a small whip one for DAB. With this one, it was able to pick up Melbourne’s DAB multiplexes reliably as long as it was near a window.

But I would rather that this unit be connected to an outdoor aerial especially for FM reception so it can provide clear signal reception. You may also be able to use a digital-optimised Band III aerial for better DAB+ reception especially on fringe areas.

You can connect an iPod or iPhone to the front USB socket using the data cable supplied with your Apple device and the sound that is played off the iPod will be converted to an analogue form using the Rotel receiver’s internal digital-analogue converter. As well, this same socket is used for playing music held on USB memory keys.

The CD player is a slot-load type that performs as expected for a decent-standard player. It can play the regular CDs or file-based MP3 discs and gives “best-case playback” for any CDs recorded with the HDCD mastering technique. This does yield to high-quality sound from these discs.

As for connection of external equipment, this is feasible with a line-in connection in the form of RCA connectors or SPDIF digital in the form of coaxial or optical connectors. There isn’t a line-out connection that is independent of the volume control for use as a recording connection, which may limit this unit’s utility with cassette or MiniDisc decks.

It is also controllable by a supplied remote control which has a numeric keypad for direct access to 30 presets in each of the radio bands – FM, DAB and Internet. As well, this remote also allows for direct access to tracks on a regular CD and is a preferred control surface when you are searching content on a well-stocked media server or using the CD receiver’s setup menus.

Rotel RCX-1500 CD receiver remote control

The unit's remote control

This unit’s amplifier is engineered for sound quality. Here, the volume control is a motor-driven potentiometer managed through the control on the front or the remote control. There aren’t any tone-control options, which may please audio purists who believe that tone adjustment affects sound quality.

The display is the white bright fluorescent display but uses four lines of text. This also works with the menu-based operation for advanced functions.

Sound quality

The sound quality for the Rotel RCX-1500 CD receiver is what you would expect for equipment in its class. This is even so with the Cabasse Antigua speakers that I am testing this unit with.

It comes across as being tight and good across all frequencies. This means that it gives all the instruments in a sound recording a proper chance rather than sounding like the old pub jukebox. This has come across so well with well-recorded rock like Peter Gabriel’s “1 – Car” album which was considered to be in the same league as Pink Floyd. Here, you still had that “punchy sound” while hearing the vocals and other instruments.

This system was even performing well with classical music especially as I was playing through a recording of Beethoven’s Violin Concerto which was done with “period” instruments. Here, the combination of this CD receiver and the Cabasse speakers shone through the whole of this popular concerto and was clear with all of the instruments.

As for handling the audio codecs, this amplifier answers the requirement for handling properly-encode music properly especially if you use the “maximum” throughput settings for the codecs like 320kbps MP3 or 192kbps WMA.

Limitations and points of improvement

The network connectivity could be improved on by not requiring the user to deal with easy-to-lose dongles. This is more so with Ethernet as most Internet-enabled hi-fi components and TVs use integrated circuitry with an Ethernet socket on the back.

As well, the Rotel could benefit from WPS setup for Wi-Fi wireless networks especially as most current-issue routers implement this easy-to-use setup method.

An improved version of this unit could support a proper tape loop and a phono input for use with a turntable especially as a lot of the older people may keep records or tapes lying around and could benefit from a simplified system with these inputs.

Conclusion

This is one network-enabled CD receiver that I would recommend for people who have a pair of good-quality bookshelf or “piece-of-furniture” speakers that they wish to keep going but want to benefit from newer sources like music held on their home network or iPod; or Internet radio. I would also consider this unit as a the core of a simplified music system if they want to choose their own good speakers.

This unit, along with the Cabasse Antigua speakers or bookshelf speakers of a similar standard, would be an ideal simple music system for use in an apartment or small house by people who place high value on music. It is especially more suitable with older retired people who are moving towards smaller flats or retirement villages.

At last a free iPhone app for controlling the UPnP AV / DLNA Home Media Network

Links

Bergin-IT Gizmoot

Direct link to iTunes App Store

My comments

This happens to be the latest DLNA controller program for the iPhone or iPod Touch and is available for free from the iTunes App Store. This program also is ad-supported through the iAd network that exists for iOS software. At the moment, it isn’t designed to work well with the iPad.

The functionality is basic in that it allows you to browse your media on a DLNA (UPnP AV) media server and have it play on a DLNA (UPnP AV) Media Renderer. This would be considered basic compared to the likes of PlugPlayer in that it wouldn’t allow you to play the media from the Media Server through the iPhone, nor would it support downloading or uploading between the Media Server and the iPhone’s local storage.

It can support playlists and slideshows so you can have your Samsung TV or WDTV Live run a sequence of media under the control of your iPhone.

I would still recommend this app for people who want to get going with UPnP AV / DLNA “three-box” setups and they have equipment that can be controlled through a UPnP AV / DLNA control point. This would be more so with network AV media adaptors which you want to press in to service for audio playback and you don’t necessarily need to have the TV on so you can select music to listen to. You may even think of using this program with that iPod Touch or iPhone 3GS that you have set aside because you have moved to the ultra-cool iPhone 4, so that the old phone can be part of the DLNA Home Media Network.

Product Review–Pure One Flow portable Internet radio (Frontier Internet Radio platform)

Introduction

I am reviewing the Pure One Flow portable Internet radio which is the younger brother of the Pure Evoke Flow radio that I have reviewed a while ago. This unit is designed along the same lines as the “old-style” portable radio that can be perched on a window sill or the top of a fridge.

The Internet radio

The Pure One Flow is the same size as a midsized portable radio and is housed in a rubberised cabinet with knobs for volume and “select” function and buttons below LCD display. The rubberised casing is a marked difference from the glossy plastic that is used on some radios, which attracts fingerprints and is hard to keep clean. I also like the knobs, especially for the sound volume because it is an interface most of us are accustomed to, where you can just “flick” the knob downwards to turn it down.

Like the Evoke Flow radio that I previously reviewed, this unit can work on AC using a supplied “wall-wart” power adaptor or battery power using a “ChargePAK” rechargeable battery pack that is available as an extra-cost option.

Pure One Flow portable Internet radio - side viewAudio connectivity is in the form of an auxiliary-in jack so you can use the radio as an amplified speaker for your MP3 player or other audio device. It also has a headphone jack which is a connection that I am noticing is becoming increasingly rare for Internet radios. The reason I find this connection important is that you could use an active-speaker system like a pair of computer speakers as better-sounding more-powerful speakers for the radio.

The set works well as a DAB-based digital radio, being able to pick up all of the multiplexes that are broadcast in our area.

For Internet-radio station selection, this unit uses a  “Form style” user interface if you intend to select a smaller group of stations but will give you the complete list of stations if you are just browsing. This is in contrast to the “tree-based” approach that most Internet radios use for selecting stations.

There is also access to a “sounds” service where you can hear sounds like sea wave; as well as access to the “FlowSongs” music download service.

This radio works properly as a DLNA-compliant media player, being able to play most audio file types that are held on UPnP AV media servers.

The sound quality for this set is very similar to an average mid-sized portable radio such as the archetypal transistor radio of the 1960s. It can still fill an average-sized room with music and the sound is focused around the middle frequencies.

Limitations and Points of Improvement

This unit could be improved with the telescopic aerial being used for the Wi-Fi wireless network as well as for FM and DAB radio.  The Wi-Fi functionality could work well with keeping the details for up to five wireless networks, which can be useful if you take the radio between multiple locations, which is something you would be tempted to do more readily with this set.

Another limitation is that you can’t enable daylight-saving time on this set. Instead, when you determine the time zone, you only can set up for standard time. This could be rectified with a firmware update which exposes a “daylight-saving” on-off function or access to a table of “spring-forward / fall-back” times hosted on the manufacturer’s Website.

Another improvement that I would like to see would be to support regular AA, C or D batteries even with a battery cage so you don’t have to look for the hard-to-get ChargePAK battery packs.

Conclusion

This set may be considered as an option when you want to replace that old “transistor radio” with something that gives you access to “modern” radio sources like DAB or Internet radio. It could he very useful where you want a set of this class to be highly rugged and durable.

Product Review–Pioneer NAC-3 Internet audio system with 2 iPod Docks

Introduction

I am reviewing the Pioneer NAC-3 (XW-NAC3) Internet music system with 2 iPod docks. This DLNA-enabled network media unit is a flagship model that heads a series of iPod speaker docks that Pioneer has recently released and is the latest attempt by this company to sell “small-set” audio equipment like portable, clock and table radios.

This Japanese company has always been known for high-quality home audio / video equipment since the 1960s and car audio equipment since the 1970s but has dabbled in the highly-competitive product class at various times through the 70s and 80s, initially selling these goods under the “Centrex” brand in some markets but eventually simply selling them under their own brand. This unit is an example of how Pioneer, along with the other Japanese consumer-electronics companies are trying to get their claws back in to a very competitive product class which is awash with many cheap Chinese-built products that are sold under many different brand names.

As an echo to the earlier attempts in the “small-set” audio product class, this unit has functionality that makes it stand out from the pack. One party piece is to work with 2 iPod or iPhone devices and play tracks from one or both of the devices and another one is to properly implement “three-box” DLNA Network Media functionality where it can be managed by a Windows 7 computer or other DLNA control point.

It will also be the first time I have reviewed a network media device and am implementing these “at-a-glance” tables for this class of device. Regular readers may have noticed that I am implementing these “at a glance” tables when I review laptop computers and printers so people can see the basic facts about these products before they read the review text.

The unit itself

Pioneer XW-NAC3 remote control

Card-type remote control

This unit has been designed to appeal to the young generation who just want something new rather than your “father’s old station-wagon”. Here, it has a shape that is similar to a banana and is finished in a glossy-white plastic cabinet. It can come with three different speaker-cloth colours – burgundy-red, black or white. As well, it comes with a card-size infrared remote control which you have to use for operating most functions including access to Internet radio.

This unit can play music from 2 iPod or iPhone devices; a Bluetooth A2DP-compliant audio source, a USB Mass-Storage Device or a line-level source as well as material over the network. But this set lacks some functions that I have been used to with most Internet radio units that I have reviewed previously on this site.

One function that it misses is the ability to connect to the host network via Wi-Fi wireless. Here, you have to connect it to the network using an Ethernet cable, but you could use a HomePlug kit or a Wi-Fi-Ethernet client bridge to connect it to the home network and want “around-the-home” flexibility without needing to lay Ethernet wiring. The other function that it lacks is access to regular broadcast radio, whether FM or DAB+ digital radio. This may not be of concern if you are seeing this unit as an Internet-enabled complementary radio / network music terminal / iPod speaker doc while you use your ordinary radio (which most households have plenty of) for listening to regular local broadcast radio.

iPod playback

2 iPod docks on the Pioneer NAC-3

You can play and charge two iPods or iPhones here

The ability to play and charge 2 iPod or iPhone devices is useful for quite a few applications. For example, a person who has one of those high-capacity “iPod Classic” series devices can still use this device as a “jukebox” alongside their new iPhone 4 that they have just signed a contract for. This is infact the demonstration setup that I used with an iPod Classic and an iPhone that I had borrowed from a teenage boy that is living with me.  Similarly, a household with many “iDevices” can this as a charging station for two of these devices. The two-iPod function is augmented by a dual-device shuffle mode which plays tracks from each of these devices sequentially. The iDevices can even be put in to “shuffle” mode so as to allow the unit to randomly pick music across the devices.

Bluetooth A2DP

The system can also work with Bluetooth A2DP audio sources like a lot of mobile phones, tablet computer (including the iPad) or some MP3 players. Here, this worked as a “Bluetooth speaker” for my Nokia N85 mobile phone and had worked as expected. The track navigation and PLAY/PAUSE buttons on the remote control had controlled the music playback on my phone.

The pairing experience was a bit confusing because there was one procedure to set up the paring code but this didn’t make the unit “open for pairing”. You actually had to press the PLAY button on the remote control to achieve this goal and begin the pairing process.

Network functionality

All the media available via the home network connection is accessed when you select “Home Media Gallery” as the function source. This includes the Internet radio as well as music files available from any of the DLNA Home Media servers on your network.

Internet radio

The Internet radio works from the vTuner Internet-radio directory and has the similar directory structure to all of the other radios that I have reviewed. It has the ability to store 30 Internet-radio stations with 10 stations in three “classes”. You will have to use this function once you regularly listen to particular Internet-radio stations because if the set loses connection with the station, you will need to “retune” to that station.

It can handle jitter and latency situations OK but as I have said before, it goes to the “Home Media Gallery” menu once it drops out and loses the connection. This can happen at busy times when the Internet service is oversubscribed and there isn’t proper QoS functionality on the network between the radio station’s server and this set.

DLNA network media

This unit integrates properly with the DLNA Home Media Network. Here, it will work as a network music player where you select your content using the NAC-3’s display and remote control; and it will even list the UPnP AV / DLNA Media Servers that exist on your network when you select the “Home Media Gallery” function so you can start “delving” in to the content on your desired server.

It also works properly as a network-controlled music player when you use a UPnP AV / DLNA control point program like Windows Media Player 12 (Windows 7) or a mobile phone with a DLNA media control program. I have even tried this with my Nokia N85 phone which I use as a personal “Walkman” and have “pushed” music held on the phone to this unit via the home network. As well, unlike some DLNA-compliant media players that are meant to work under network control that I have used, this unit will even play a program of music that you direct it to play from the network-based control device.

Sound Adjustments and Quality

There are bass and treble controls accessible from the remote control but I had kept the bass and treble set at “flat” so as to hear a sound that I can assess fairly. There is a “sound-effect” button which allows the system to be switched between a “vivid” mode with a bit of extra bass and treble, a “Lo-Fi” mode which yields a cheap transistor-radio sound and an “ALC” mode which keeps the sound level constant for use in noisy environments.

Even if I don’t use the sound-effect modes and I have the bass and treble flat, this Internet radio doesn’t sound like a “gutless wonder”. There is still some punchy bass even with popular music that was recorded before there was the desire to make such music sound boomier and louder. Yet you still hear the vocals and instruments that carry the body of the music clearly and distinctly. Even the heavy bass lines from the recent dance tracks that were on the iPod and iPhone that I borrowed from the teenager to try out the dual-iPod functionality didn’t worry this music system much and they still sounded “tight” – there wasn’t that old bass-heavy “jukebox” sound.

Limitations and Points of Improvement

The Pioneer NAC-3 Internet music system could benefit from integrated Wi-Fi wireless-network or HomePlug powerline network connectivity. This is more so because it is the kind of network device that appeals to being taken around the house from room to room.

It could also benefit from a headphone jack because some people use this jack to connect a more-powerful active-speaker system or an amplifier to these devices for increased sound output. As well, the VIDEO output on this unit could be used not just for iPods and iPhones that have a video output. Here, this jack could work with the DLNA network media player to play pictures and video material through a connected TV set.

The Internet radio functionality could have some improvements in the way it operates. It could come back to the “last-tuned” Internet station or attempt to reconnect itself after a dropout. But this may have to be facilitated through a separate “Internet Radio” function on the function selector like what most other Internet radios have.

Conclusion

I would recommend this unit for people who either run two or more iPods or iPhones; a Bluetooth-enabled music-capable phone or have established a DLNA Home Media Network and want a “complementary” transportable device that can get the most out of their digital music library available on their portable devices or home network.

Consumer Electronics Show 2011–Part 2

The Android technology doesn’t stop at handsets or tablets anymore at this year’s CES.

In the car

Parrot are premiering the “Asteroid” which is an Android-powered car radio / multimedia player. It has USB for connectivity to iOS devices, USB flash memory, wireless-broadband modems and GPS pucks at the moment as well as line input for regular audio devices. I am not sure what Bluetooth or hands-free calling abilities it has at the moment but this could change by the time it is released. Of course it has FM radio and, through the 3G connectivity and an Android app, could support Internet radio in the car as well as being a media player and GPS navigation device. It has a power output of 55W x 4 but also has three preamplifier outputs (front, rear, subwoofer) so it can be the head unit for the most tricked-out sound system on the street. Oh yeah, boys!

Similarly, Fujitsu Ten are previewing an satellite-navigation unit which is powered by the Android operating system. The main issue with these Android systems at the moment is that the Google “Android Marketplace” doesn’t support them because they use an interface that is dissimilar to the handset or tablet devices. Here, Parrot or Fujitsu Ten will either have to contract with an Android app store to supply applications to these devices and this app store would have to support the user interfaces provided by automotive Android devices.

In other car-tech news, Ford have developed an AppLink system so that specific iOS apps can be operated from the car’s dashboard. As well, General Motors have developed an IOS link to their OnStar vehicle telematics system but the main problem with these systems is that they necessitate an extra app on the smartphone for each marque. This is compared to Terminal Mode which the European vehicle builders are implementing, which allows one piece of software on the smartphone for many different vehicles and suits the reality that most of us will drive different vehicle marques through our driving life and even have regular access to two or more different vehicles.

As well, GM are intending to implement the PowerMat wireless-charging system in the  American-market vehicles from model-year 2011 onwards. This allows devices with Powermat charging circuitry, whether integrated or as an add-on module to be charged or powered on a special mat wirelessly. I have wondered whether this announcement will then apply to GM nameplates other than Buick, Cadillac, Chevrolet or GMC or other markets.

Networked Home Entertainment

Video Entertainment and the Home Theatre

As far as video-based home entertainment goes, 3D video still rules the roost with every one of the major camera names from Japan with a 3D camera or camcorder in their model lineup. As well, every major TV brand that serves the US market is selling a 3D flatscreen TV in their model lineup. Most of the manufacturers are working on 3D viewing technologies that either don’t need glasses or can work with lightweight glasses. This also includes some manufacturers establishing design partnerships with glasses-frame designers to make attractive 3D-viewing glasses.

But there is a lot more action when it comes to network-enabled TVs and video peripherals This is again driven by the supply of  “over-the-top” Internet video services like Netflix and Hulu Plus. It is also being helped along by manufacturers building up “app platforms” which allow the user to download apps to the TV as if it was like one of the smartphones. It can capture the reality of interactive TV as well as use of common Internet services like Twitter, YouTube and Facebook from the comfort of your couch. As well, programs like Skype are being implemented on these TVs in order to make them become large-screen video-conferencing units for the home or small business.

LG have supplied the ST600 Smart TV kit, which is an add-on kit for selected (or all?) LG TVs to link them to the Internet and the DLNA Home Media Network. As well, one of their pico-projectors that they had on show is equipped with an digital-TV tuner and can stream content from a DLNA Media Server.

Sony now has it that all of their new Blu-Ray players are all DLNA and Gracenote enabled/ They all can quickly start a Blu-Ray movie and have support for the “Media Remote” RF link with Wi-Fi-enabled iOS or Android device running a specific app. These same features are also available to their Blu-Ray home theatre systems.

As well, most of the Sony BRAVIA TV range released this year will be network-enabled with DLNA, Internet TV, Skype large-screen videophone and similar functionality. Some models will have integral 802.11n Wi-Fi functionality while the lower-cost models will require a dongle to connect to the Wi-Fi network. This really shouldn’t worry most users because they could use direct Ethernet or HomePlug AV links to connect the TV to the home network.

The Skype videophone function will work with an optional USB webcam / microphone kit that will be available from Sony.

As well, most of the TVs and home-theatre systems honour the full HDMI 1.4 expectation with Audio Return Channel. This means that the sound from the TV’s integrated sources like the digital TV tuner travel back to the home theatre amplifier using the same HDMI cable used to connect the TV to that amplifier. There is no need to use extra digital cable runs to have properly-decoded surround sound from TV broadcasts received via the TV’s tuner.

As well, Sony has released a network-audio product that makes Apple squirm when it comes to their Airport Express and AirPlay subsystem. This product which comes in the form of the HomeShare speakers connects to a Wi-Fi home network and can play out audio content under the control of a UPnP AV (DLNA) Control Point like Windows 7 or TwonkyMedia Manager. This same control functionality is also available in Sony’s latest Blu-Ray Players as well as the NAS-SV20 and NAS-SV10i iPhone docks.

Samsung have come around with a Blu-Ray player that is the thinnest such player ever. This Wi-Fi-enabled player can be wall-mounted and, in my honest opinion, is cutting in on Bang & Olufsen’s “design AV” territory.

They also are releasing the D6000 TVs  which work with RVU compliant pay-TV gateways. This standard, which is a superset of DLNA for pay TV applications). enables access to the full pay-TV feature suite like pay-per-view or video-on-demand without the TV being connected to the pay-TV operator’s set-top box/ This concept has been proven to works with an RVU server box that links to DirecTV’s satellite pay-TV service.

Iomega have also released a Boxee TV set-top box which is similar to D-Link’s unit. But the similarity stops here because it has integrated NAS functionality with DLNA Media Server. It is capable of working with Ethernet wired or 802.11n Wi-Fi networks and uses a double-side remote with QWERTY keyboard. It is available as an enclosue or with a 1Tb or 2Tb hard disk.

Vizio, a low-cost TV brand in the US similar to Kogan, is to implement Via Plus (Google TV) in their Internet-enabled TVs. They will be providing apps that link to Hulu Plus, Blockbuster On Demand, and other popular “over-the-top” TV services. These sets will also have Skype functionality when used with a USB webcam. Vizio will also be implementing glasses-free 3DTV and are dabbling in 21:9 ultra-widescreen TV

Cisco have been focusing on the interactive TV front but in a different way. They sell  the Scientific Atlanta set-top boxes on contract to cable and satellite providers and are implementing an app platform on their newer boxes. This also means that they are providing a “VideoScape” content-selection experience so that users can find the content they are after or look for related content easily.

JVC have released the first “soundbar” speaker system which implements the HDMI 1.4 Audio Return Channel. Here, this technology comes in to its own with these speakers because the sound from the TV emerges through the easy-to-set-up soundbar unit.

Internet radios

Grace Digital have released three Internet radios that have a similar user interface to the Grundig TrioTouch stereo Internet radio or the Revo IKON stereo Internet radio. Here, these sets use as their primary user interface a colour LCD display with icons laid out in a grid not dissimilar to a smartphone or tablet. The Mondo is designed to be a full-on clock radio for the bedside and has a 3.5” display, Ethernet and line-out connectivity and a remote. The Solo Touch is a tuner that connects to one’s favourite music system and has a large 4/3” touchscreen. It connects to the home network via Ethernet. The Bravado X is a stereo table radio with line in / out and has a 2.7” display. These units can also be controllable via a smartphone app which is available for the iOS only at the moment.

As well, Vizio have jumped on the Android bandwagon by providing a stereo table radio which operates on the Android platform. This one is controlled by a colour LCD touchscreen like the typical smartphone. It would most likely would have an Internet-radio app and also pull in music from a DLNA Media Server device.

The next article in the series will focus on network-infrastructure technologies for the small network and what is being offered here.

A digital camera that can be controlled by a smartphone

CES: Samsung SH100 camera wants to be BFF with your smartphone – CES 2011 CNET Blogs

My Comments

At this year’s Consumer Electronics Show, Samsung had demonstrated a compact digital camera which has integrated 802.11n Wi-Fi functionality. It would have the usual benefits like uploading pictures to a computer or cloud-based storage service; and exhibiting pictures on a DLNA-compliant video-display device.

But this camera has a feature that has impressed me very much. It is to use the Samsung Galaxy S smartphone as an external viewfinder and control surface. This has been a function that I have been wishing for with digital photography and cinematography.

Here, this would work well with a photography situation that most of us encounter. When we are at a party or nightclub, we may want to take a picture of everyone on that dance floor dancing to that dance hit thumping through the speakers. Similarly, we may want to get a picture of the live band playing at that pub gig which is packed out. When we are outdoors, we may want to grab a picture of the floats that are part of the parade for example.

In these situations, you may need to lift the camera over your head but you won’t get a fair idea of what you are to photograph due to a small screen size or viewing the screen at an “off angle”. Here, you just end up taking a large number of “rough shots” that you will end up editing out for example.

Similarly, if you use your camera for wildlife photography for example, you will find it hard to take the right shot because the moment you get near the camera, you spoil the shot.

Here, Samsung has established a wireless link which uses the phone’s screen as a viewfinder and control surface for the camera. The user would have to download an app to the phone in order to achieve the functionality. This link is also set up so that pictures can be sent to the phone for sharing via the phone using MMS, email or Web-based services.

There have been further questions about other smartphones, whether based on Android, iOS or other platforms being able to have this functionality. What actually needs to happen is for device classes to be defined or existing device classes reused and amended for photographic / cinematographic applications. This is to provide remote viewfinder and status display as well as remote control of the shutter / recording start-stop and other aspects of the exposure. Similarly, the device classes also have to provide control of flashguns and other lighting in order to synchronise them with the exposure.

Here, the device classes should work with USB wired connections as well as wireless Bluetooth or Wi-Fi connections.

Similarly, cameras could implement USB “On-The-Go”, Bluetooth “Object Push Profile” or similar technologies to allow a user to upload a picture to the phone. As well, the phone could provide dynamic scale-down of high-resolution images when sending pictures by MMS or email. This would avoid me having to take pictures with the phone rather than my digital camera if I intend to use the picture for a picture message for example and I can still use the good-quality imaging attributes of the camera to yield a good quality photo.

At least Samsung has taken a step in the right direction by enabling a digital camera to work with a smartphone for improved photography.

A DLNA-driven electronic-picture-frame and NAS system concept – what could it offer

The current situation with electronic picture frames (digital picture frames)

I have been to a friend’s home and had seen an electronic picture frame that they received for a previous Christmas sitting on their sideboard, turned off and hidden behind other framed pictures on that same sideboard. This picture frame has some old pictures that the close friend doesn’t really want and their granddaughter has to come up from the country with a memory key full of images in order to update the picture frame’s collection. Similarly, I have noticed that our household and another household are becoming the two households that are involved with updating an electronic picture frame belonging to a close friend.

This usually sees most households in situations where managing the typical sub-$100 electronic picture frame becoming very tenuous and ends up being a serious task if one has to update many of these frames that are spread across the households that make up an extended family. This situation would typically be in response to a family event like a wedding, the arrival of a new baby or a family reunion.

If the event happens overseas, the family members will need to email the pictures or send them using Flickr, Facebook or similar online services to nominated family members in other countries. Then it’s the job of these family members to push the pictures to optical disks, SD cards or USB memory keys for uploading to relatives’ picture frames.

There are some online picture frames on the market but these are tied to particular services which may require the user to take out a subscription. Similarly, some of the frames also require the user to run special manufacturer-supplied software to deliver pictures over the network to the frame. As well, a lot of Wi-Fi-enabled picture frames on the market are not DLNA-compliant thus wouldn’t work with most network-attached storage devices or storage-enabled routers on the market.

Infact one close friend of mine who had taken me shopping for my birthday present had noticed me looking at network-attached storage devices and looking carefully for the UPnP and DLNA logos on the NAS device’s box before I offered it as a possible idea for a group gift. I had later explained that this kind of functionality was to be a step in the right direction to an easily-manageable digital-image-storage system once connected to DLNA-compliant Wi-Fi picture frames.

How could the DLNA-based system be built

The components

The digital picture frames

There would be one or more DLNA-capable electronic picture frames or similar devices connecting to the home network by 802.11n Wi-Fi, HomePlug AV or other similar means. These devices would be DMR devices which permit other devices on the network like network-enabled remote controls to determine what is shown on the devices.

The media server

A DLNA-enabled network-attached-storage which works with a unique POP3/IMAP email inbox or established cloud-driven image-delivery service can work as the picture storage centre. Pictures can be uploaded locally via a USB port or SD card slot(“quick drop”), via the network using CIFS or NFS (common network file-handling protocols) or the unit can allow FTP/HTTP “block upload” for remote uploading or simply allow the user to email photos to it.

Other devices such as another of the picture frames or the network’s Internet-gateway device could work as an alternative primary or secondary media server. This may be achieved through the devices using flash-memory technology or a small hard disk; and may be applicable for receiving emailed images or images from online services. They could even work with a NAS by “offloading” images to that device when new images come in.

Metadata

The server device would make use of established metadata tag families like what is used with Windows Live Photo Gallery and iPhoto for indexing the collection and allowing various search and browse options. It is alongside use of file-system and date/time hierarchies that would be typically used by these devices. These include keyword-browsing with support for user-created “keyword trees” as well as multidimensional searching. The DLNA server software should support the newer person-tagging and  place-tagging functionality that newer image-management software offers as well.

Sydney Harbour Bridge

Do we tag a picture of the Sydney Harbour Bridge as simply "Sydney" or as "Sydney Harbour Bridge", even as a sub-tag of Sydney?

An issue that may be of concern with place-tagging is how one tags places in a town. One may tag “general” or “landmark” pictures with the name of the town or establish a hierarchy based on the town’s name and a tag list for the landmarks. They may not use this tagging system when it comes to pictures of particular locations that they have visited like homes, offices or similar places.

Another metadata form that could be supported for people who make the time to work with metadata is the creation of horizontal or vertical “pan lines” in a picture. These lines would determine how a picture frame pans across a picture that is too wide or tall for it and can avoid us seeing the bodies of the subjects that are in a group photo for example.  These “pan lines” can also have “home points” in the picture to allow for the photographer to have control over default static presentation on horizontal or vertical displays. 

Control

The picture frames or the controller need to be able to select multiple UPnP collections and show the pictures in these collections in a sequential or random manner. It can also include whether to play the videos with sound or not at certain times of the day in order to avoid the sound track being of nuisance value.

Advanced playback control options

Frame groups

One or more of the picture frames which have controller capability or a separate controller device / application the ability to “push” pictures from one collection or set of collections to one group of frames such as frames installed in the lounge room. This function would require that random pictures from the collection or set of collections are shown on each frame in the same group.

A frame could be a member of many groups rather than just one group. An example of this could be frames that are placed on the mantlepiece being their own group but being part of a super-group encompassing all of the frames that are in the lounge room for example.

Event-driven playback

The controller could support timed playback so that particular collections of images and content are shown to particular frames or frame groups at certain times or in response to certain events. An example of this could be to exhibit Christmas family pictures from Advent through to Epiphany; or show pictures of a city that you intend to travel to for two weeks before the journey. Another example would be to immediately show newly-arrived pictures on certain frames as soon as they come in or be “slaved” to an intruder-alarm / access-control system that is configured for individual household members and show favourite pictures to particular household members when they come in.

Picture Sources

Most pictures will be imported from digital cameras via one or more networked computers. Here, the pictures may be edited and tagged with appropriate metadata, then they will be synchronised to the network-attached storage drives for availability across the network.

Images delivered by email

A key question that will be raised is which device checks for new pictures that have come in by email? Is it the network-attached-storage unit, the Internet-gateway-device (broadband router) at the “edge” of the network or one of the electronic picture frames?

  • If the network-attached-storage checks for the pictures, it will have to check a known email address then copy pictures to a particular directory. This may be easier for a multi-frame system because it is a device that is suited to being kept available all the time.
  • If the Internet-gateway-device is to do the job, it will have to check the email address and store incoming pictures to a particular directory on integrated or attached mass-storage like an SDXC card, solid-state drive or hard disk. Then it will upload the pictures to the network-attached-storage at regular intervals. As well, it will also be required to be a DLNA server in order to share this directory with the picture frames so the newest photos of the new grandchild are highly available.. This may be OK if the only device you want to keep available when you are out is the Internet-gateway-device. It may also be OK if the intention is to make the Internet-gateway-device become a central storage server for the photos, which is something that may be desired of by manufacturers who want to provide a “one-device-does-all” solution for the network-Internet “edge”.
  • The electronic picture frame solution will be similar to the Internet-gateway-device solution but this will again  require a third device to be highly available to share or upload the pictures. This device may be able to display the pictures as soon as they arrive then upload them on a regular basis. It will also be required to have a large-capacity rewriteable mass-storage system like an SDXC card on board.

Device manufacturers and Internet providers may prefer that their device is the one that collects emailed pictures and this could lead to some confusion when you add a device to this ecosystem.

When picture arrives by email, the router, picture frame or network-attached-storage device would copy the pictures to a “new pictures” directory. This directory would be  distinctly selectable on UPnP AV clients and contain these new pictures. Pictures older than a user-determined time would be pushed in to the main photo collection so they can be available for viewing. As well, users can move the pictures to the main collection and add appropriate metadata to the pictures using a regular computer connected to the network.

Integration with online services

A lot of us do work with online photo albums, whether as dedicated sites like Flickr, Photobucket or Picasa Web Albums; or as part of a social-network setup like Facebook. There will then be the desire from both the service providers and their users to integrate the photo collections with the DLNA Home Media Network.

The device that works as the “hub” may have to regularly visit these sites and cache the pictures from the albums to the local mass-storage in order to provide constant availability of these pictures. One issue with this is whether to allow the device to cache every album that its associated account has access to or allow the user to nominate albums or “peers” (friends, Pages, etc) for caching. This is important with users who have a large number of “peers” that they subscribe to from these services.

As well, there would be the issue of establishing a UPnP Content Directory tree which works in this order: Service (Facebook, Flickr, etc) – Account (own account, each “peer” account (Facebook Friend, Page, Picasa Friend, etc)) – Album / Photostream (including images in account’s “root” album).

Support for and integration with premium content

An option that is being encouraged with some networked picture frames is the delivery of commercial content such as clip-art / stock-photo images, news-photo images (useful if you are associated with a news article) and comic strips / cartoons. Similarly there could be such content as “information screens” (news, weather, etc) being delivered to these frames.

Here, it may be worth considering where this kind of premium content should be held and how new providers are added. This could be driven by an “app” model where customers can add content sources in a similar manner to what is being done with the iOS and Android platforms.

Conclusion

Once these ideas are looked at and the concept of DLNA-driven digital picture frame management is achieved, this could increase the utility of the digital picture frame and other image-display devices as a way of showing the increasingly-large library of digital images.
