Bang & Olufsen unveils Playmaker wireless audio bridge, makes sure AirPlay and DLNA speak Danish – Engadget

From the horse’s mouth

Bang & Olufsen – Product Page

My Comments

Previously I had touched on Bang & Olufsen launching the Beosound 5 Encore which is their first DLNA-enabled music system that put Sonos on notice as far as “cool” hard-disk-based music systems were concerned. Again B&O have launched another music system which, this time, can be driven by a computer or a mobile device, achieving this same goal of effectively putting Sonos on notice.

This device, known as the Playmaker, can connect to any B&O Beolab active speaker system and works to the AirPlay or DLNA Media Renderer standards, thus being able to be under the control of a computer running iTunes, TwonkyMedia or similar software. Even your iOS device running its stock iTunes implementation or your mobile device running a DLNA controller app like TwonkyMobile or PlugPlayer can be the control point. Of course, you could adjust the volume or move between tracks using a Beo4 or Beo6 remote control.

Like an increasing array of network media players made by companies who have their feet planted in good sound, the B&O Playmaker supports FLAC and other codecs considered as part of high-grade sound reproduction. This is in the same manner as what I was often seeing at the Australian Audio & AV Show at the Melbourne Marriott Hotel where all of the network-capable audio systems were working to DLNA setups and using FLAC and other high-grade audio codecs.

Here, this Danish design king has provided two paths for DLNA-based audio – a system with a local control surface and display in the form of the Beosound 5 Encore and a system that is managed entirely from remote control in the form of the Playmaker. These are another example of “audio companies of respect” embracing standards-based high-grade network audio reproduction.

As I have also said before in the article on the Beosound 5 Encore, this is one design masterpiece that would come in to its own playing that piece of European chillout music in that trendy inner-urban café, wine bar or beauty salon.

Sony STR-DN1030–A home-theatre receiver that could just be connected to a screen, speakers and the home network

Article

Sony STR-DN1030 AV receiver with AirPlay, WiFi and Bluetooth starts shipping – Engadget

My Comments

Since the 1960s, the stereo receiver had, like some other pieces of hi-fi equipment, become a “starting piece” for many hi-fi systems. Here, it would mean that the unit, once connected to some speakers, could simply do something like give you access to broadcast radio content. Then, they could take a “building-block” approach to establishing a hi-fi system by purchasing a turntable, CD player or cassette deck as they can afford the equipment.

Sony have worked on this concept with this latest home-theatre receiver by having it able to pull in broadcast radio or be hooked up to a home network for Internet radio, IPTV, content held on a DLNA Media Server or content held on your smartphone or portable media player. But, like with other video peripherals, Sony have pressed the STR-DN1030 in to service as a “smart-TV” terminal.

A design issue that needs to be looked at with these home-theatre receivers is whether they have to be dependent on a TV being on all the time they are in use. I see this being of importance if you are using the receiver to listen to audio content from the Internet or from a home-network source, and you shouldn’t have to “light up” the TV just to select this content.

This reminded me of visiting a friend’s hotel room and “flicking around” the radio content on the TV; or another friend who sent me a picture of their hotel TV tuned to a favoured London radio station when they were in London. Similarly it reminded me of an ultra-cheap DVD player hooked up to a friend’s home theatre system and pressed in to service to play music from CDs for a housewarming. These situations had a television set “lit up” just so that audio content can be navigated.

What I would like to see more with the video peripherals serving as smart-TV terminals is that they capitalise on their strengths yet are like the video cassette recorder. This is where they can augment any old TV with this kind of online TV functionality.

DLNA now part of Nokia Lumia WP7 phones with Play To app

Article

Nokia’s Play To app now available for Lumia devices, enables DLNA-connectivity – Engadget

“Play To” DLNA App for Lumia’s Already Available in Marketplace | My Nokia Blog

My Comments

A feature that Microsoft should have provided as part of the Windows Phone mobile operating system but provides as part of the Windows 7 desktop operating system is the “Play To” function. Here, it allows you to push pictures, audio content or video content from your device to a DLNA-compliant network media player that can be controlled by other devices.

A question I have pondered about this operating environment is whether one could play content held on the phone or on a DLNA-compliant network media server through that smart TV or network-capable home-theatre receiver using one of these phones. Now the question has been answered with this app being available for the platform.

But, personally, I would like to see this available on the Windows Phone MarketPlace as an app for any WP7 phone and work in a “full” manner with network and local content. This means that it could download content from a DLNA NAS to the phone, play out content to a DLNA device, upload photos and video content to a NAS with DLNA upload functionality as well as cause content held on a media server to be played on a media-renderer device. This could them prove the Windows Phone 7 as part of the industry-standard media management landscape.

Pioneer SMA wireless speakers put AirPlay, HTC Connect in one happy family — Engadget

My Comments

Pioneer have released a range of single-enclosure wireless speakers for use with smartphones, tablets and laptops. But they are not the typical Bluetooth wireless speakers that one would ordinarily think of.

Here, they can either work with a small network whether by Wi-Fi wireless or an Ethernet connection; or they can become their own Wi-Fi access points. They implement Apple AirPlay or the common DLNA 1.5 Digital Media Renderer protocols which makes them work with Apple or industry-standard portable-media playback setups. 

They also have a USB connection for directly connecting one of those high-capacity iPod Classics that is full to the brim with music or other iPod / iPhone devices; as well as having a line-in jack for other media players or tuners; or simply serving as extension speakers to an existing sound system.

The difference among the models is the ability to work on battery power or the speaker setup used in the units. The cheapest model, the XW-SMA1 uses a 3” speaker for each channel and a 3/4”  tweeter for both the channels and doesn’t have battery power. The step-up model, the XW-SMA3 uses the same speaker configuration but can run on its own lithium-ion battery for 4 hours at maximum volume. The top-of-the-line model, the XW-SMA4 has the battery power but can yield better bass through the use of a 3” speaker and 3/4” tweeter per channel and a 4” bass speaker (subwoofer) shared by both channels.

What Pioneer has done is to achieve a highly-compatible wireless speaker set that can work with the standard DLNA-compliant home network which could be based around Windows computers and Android smartphones as well as being able to please the Apple fanbois. This is able to be done without having to resort to Bluetooth technology.

If I was choosing one of these for summer outdoor fun, I would go for the XW-SMA3 or the XW-SMA4 if you value that bassline in the music. The battery-power ability can come in to its own when you are near the pool or on the deck without needing to run extension cords everywhere.

WD now is in the network-infrastructure scene

Press Release

Product Website

My Comments

Last year, I reviewed the Western Digital LiveWire HomePlug AV network kit which comprised of two 4-port Fast-Ethernet switches that were able to link to each other via a HomePlug AV powerline segment. Initially I though that WD had run this product simply as a “flash-in-the-pan” product while focusing on their storage and media-streaming products. But it became a taste of things to come for WD when they released more network-infrastructure hardware over the last week.

They, like Belkin, AVM, Linksys and a few others, have taken the step of focusing their efforts on the consumer, SOHO and small-bsuiness space rather than running products for larger managed networks before tackling this space. But WD had crept in to this space with network-attached storages for home and small-business, then offering the WDTV Live lineup of network media players before tackling the network-infrastructure market.

But what has happened further is that the devices are set up for the expectations of next-generation broadband Internet. For example, the My Net routers are dual-band dual-radio Wi-Fi access points that work as dual streams on each of the bands. As well, all of the routers except the economy N600 model use Gigabit Ethernet for the LAN and WAN connections and handle IPv6 networks. The top-shelf N900 even has 7 Gigabit Ethernet ports, which makes it able to work as a hub for a home that is wired for Ethernet.

These routers can provide media content to the DLNA Home Media Network when they are connected to a USB external hard disk full of media.

As to integrate their hard-disk prowess, WD have released the N900 Central which is effectively the N900 and a My Book Live network-attached-storage in one chassis. This comes in either a 1Tb or a 2Tb capacity and can act in the same capacity as a network-attached storage, including sharing media to the DLNA Home Media Network.

But WD have not forgotten the idea of an Ethernet switch. They have also released the My Net Switch which is an 8-port Gigabit Ethernet desktop switch with port-based quality-of-service management. The limitations with this setup include requiring that the QoS benefits only affect traffic passing through that switch and that you may have to revise the connections for different applications if you are using it as a “central” switch for your wired-for-Ethernet house.

Who knows how these home-network products will fare in the onslaught of the likes of Netgear and D-Link and whether WD could innovate this class of product further and get a foothold in the connected home and small business.

The Aperion Aris, a Windows-only wireless speaker which is really a DLNA wireless speaker

Article

Meet the Aperion Aris, a Windows-only wireless speaker | Crave – CNET

My Comments

Not everyone has to have an Apple device like an iPhone or iPad but a lot of audio devices, especially network-enabled speaker systems, seem to be designed so that they work best with Apple devices.

Now there has been exhibited a network-enabled single-piece speaker that is pitched at platforms other than Apple. This unit, the Aperion Aris, has been billed as working only with Windows 7 and 8 by supporting the “Play To” functionality in these regular-computer operating systems.

But the “Play To” functionality is actually about UPnP AV / DLNA MediaRenderer functionality and should work with other UPnP AV / DLNA audio control point software. This could really mean that your iOS, Android or Windows Phone 7 mobile device could drive this speaker if it runs TwonkyMedia, AllShare or other DLNA control point program.

But an Apple Macintosh computer can still work with this speaker if it is running a DLNA media-controller apps. Examples of this include Songbook Mac, TwonkyMedia or PlugPlayer, the latter of which is available through the Mac App Store.

The speaker system is based around a six-speaker design that has two drivers per channel and two passive-radiators with a claimed power rating of 50 watts per channel. But it would be really interesting to hear how it sounds as in whether it can fill an average room with sound and whether there is some “punch” in the sound.

Personally, I would like to see network speakers support AirPlay and DLNA or at least use DLNA as a common denominator due to the level playing field that this standard offers for network audio delivery.

Product Review–Western Digital WDTV Live (2011 version)

Introduction

Previously, I reviewed the 2008 version of the Western Digital WDTV Live network media player and found that there are some areas where it could be improved on. Now I have been offered the latest iteration of this network media player for review and this review will be an interesting exercise to compare it to the previous model.

The media player itself

Western Digital WDTV Live network media players - comparison between generations

WDTV Live network media players - earlier version below 2011 version

The current edition of the Western Digital WDTV network media player is the similar size to the previous-generations of this network media device but is finished in a newer style with an obvious infrared-remote receiver and an upfront USB socket for memory keys and hard disks. It doesn’t have the “book-style” shape as the previous model and is pitched as a unit to go with a cluster of consumer-electronics equipment.

Connectivity

The WDTV Live’s audio-video connections are similar to the previous model except that there isn’t the component video output jack. This is meant to assume that this device will work with the flat-screen TVs that have the HDMI connection or the legacy CRT TVs and video projectors that use the composite video connection for their external video devices. You still get a breakout cable with 3 RCA plugs on the end so you can connect this device to most of these TVs, in a similar way as you would with most smartphones and some digital cameras.The previous version of this device was a “Wi-Fi ready” device in that it required the user to purchase an additional USB Wi-Fi network adaptor dongle and plug it in to the unit. This time, the WDTV Live comes with the Wi-Fi network adaptor integrated in to the unit and is how I tested the unit.Front view of current model and earlier model

The Wi-Fi connectivity is set up for 802.11g/n wireless networks and supports wireless routers that implement consumer and small-business security methods i.e. WEP and WPA(2)-PSK, including WPS quick-setup routines. The latter can be started from the TV screen through the WDTV Live’s setup menu.It is still sensitive enough for most interactive-TV applications and standard-definition viewing but I would recommend using the Ethernet connection with a HomePlug AV adaptor (if necessary) for better and more reliable throughput.

User Interface

Western Digital WDTV Live remote control - 2011 model

Remote control

The menu structure and user interface was more like an XBox 360 with recent firmware than the previous model’s interface which reminded me of the XrossBar interface used in Sony’s connected consumer electronics. Here, this interface was able to still work well even with legacy CRT TVs because of having the selected option in the centre and brought up.

It also used the “coloured function buttons” on the remote control which is the trend for consumer video equipment. Here this was used for applying filters or changing list orders for content and other lists. This is compared to the user using a D-pad to do all the control on this device which was the case with the previous model.

Applications

I have tried some of the services that come with the system and have noticed that YouTube comes with two user interfaces. One feature that I liked with this YouTube application was that it was able to cater for multiple users. This meant that it held the Google usernames of previous users in memory so different users can log in to their personal user profile and is a step in the right direction.

As far as the Facebook app is concerned, it is totally broken in that it can’t show the photos that are part of the social-media service. You don’t even see the profile pictures for your Facebook Friends, which makes for a disappointing experience with this device. You could see the text on the various Walls or Feeds that you subscribe to and post text-based comments but that’s all.

Most other photo and video applications work as required and the streamed videos and audio content come through smoothly. This is even though I was using it on an older “classic” TV set.

UPnP AV / DLNA

The UPnP AV / DLNA experience that the WDTV Live provides  is still the same as the previous models in that when it comes to photo and video content, it’s slow to load off the network. You can still “pull” content down from your MediaServer device like your NAS using the remote control and the on-screen user interface but the WDTV Live doesn’t work well when pictures or video content is “pushed” to it under the control of a control point.

This could be improved with read-ahead caching and proper handling of queue lists which would be important for this class of device. Once this is ironed out, it could make the WDTV Live media player become a cost-effective tool for network-based content playback including digital signage for the small business.

Limitations and Points of improvement

One main limitation with the WDTV Live family is that it doesn’t support any of the catch-up TV / video-on-demand services that are currently available for the Australian and New Zealand markets like ABC’s iView or the Plus7 service. I have seen other devices including Sony’s BDP-S380 offer this kind of functionality which would bring these services to how they should be enjoyed – relaxing on the couch and watching on the big screen TV.

But personally I would like to see the device’s software and hardware re-engineered for better network and Internet performance. This was also confirmed to me by a close friend who bought the same device and found it didn’t perform as well as it should.

As well, Western Digital could make the next or subsequent generation of this device part of a DLNA-driven multi-room PVR setup for broadcast TV. Here, they could use a box with a hard disk for recording TV shows from a cluster of ATSC / DVB-T front-end tuners using an electronic programme guide. As well, this box is managed by any device compliant with UPnP AV version 4 such as next-generation WDTV Live boxes, allowing for scheduling of TV programmes and bookmarking (shift between viewing locations) amongst other functions.

Conclusion

At the moment, I wouldn’t really recommend the WDTV Live in its present incarnation and would like to see the arrival of cost-effective video-based network media players that have access to the full plethora of network media services and work responsively and properly for the DLNA Home Media Network whether under “pushed” or “pulled” conditions.

Consumer Electronics Show 2012–Part 2

Audio and VIdeo

Smart TV

There is still intense interest in the smart-TV platforms where your TV is effectively a computer connected to the Internet. This is more so with the idea of integrating multiple viewing screens ie the large TV screen, one or more computer screens, and the screens on tablets and smartphones.

Sony have been dabbling with the Google TV platform, mainly in the form of network video peripherals rather than a TV, which I will mention below. Of course, they are still maintaining their Bravia platform. They were also to promote this concept in a Las Vegas wedding at the Bellagio Wedding Chapel between “Bravia” (Sony’s Internet TV platform) and “Sony Entertainment Network” (Sony’s online content entity).

As far as the interactive-TV lineup goes, Sony have focused this function across their HX and EX “lounge-room” models with the HX series being ready for Skype once the user purchases an optional camera.

Samsung have devoted most of their press event to the TV being the “smart hub” of the connected home. This is with the use of a connected TV chassis that has a dual-core CPU, as well as building up the “Smart TV” platform around an app store and a video-content-distribution platform. They even are using an Android app as the TV’s remote rather than supplying the remote with the TV set. They even ran a competition for the development of a multi-screen app which makes best use of the TV screen alongside a smartphone or tablet screen.

As well, Samsung put forward an “open-frame” design for TV sets with a user-upgradable computer processor. This is in a similar way to how the desktop computer has been designed and is underscoring the fact that these smart TVs are really large-screen computers in their own right and are expected to last for in the order of ten or more years.

Even Lenovo had come to the fore with a 55” LCD set that is driven by the Android “Ice Cream Sandwich” operating system. This would link to their own app store and cloud services and have the usual “smart-TV” features like Wi-Fi connectivity and ability to use an SD card as storage.

Similarly, a “fork” of the Ubuntu Linux distribution, which was targeted at the Internet-enabled TV set, had been launched at this show.

Ultra-high-definition TV

Another main trend surfacing this year at the Consumer Electronics Show is ultra-high-definition TV, also known as UDTV or 4DTV. This is where images have a resolution of 3840×2160 pixels and is pitched at the very large screens of 103” and bigger.

LG is intending to demonstrate an 84” prototype set which works at this resolution while Sony even had the idea of having some of their Blu-Ray players upscale the 1080p video to the higher resolution offered by this newer technology.

3D TV

The main trends affecting this technology are glasses-free 3D screens where you don’t need to wear glasses to watch the 3D effect; use of cheaper cinema-style passive 3D glasses which don’t need to link to the set or require batteries; as well as standards-based active glasses systems.

Toshiba is launching a glasses-free QFHD 3D TV 

OLED as a TV display technology

LG and Samsung have made efforts to bring the OLED display technology to the living-room TV size. Here, they have proven it by demonstrating 55” TV sets that use this technology rather than the LCD or plasma technologies for their screens.

There were rumours that Sony was to dump OLED technology for TV displays but they wanted to refine it to a cost-effective point for professional and consumer users. They have also shown a “Crystal LED” screen prototype which works in a similar vein to LED screens used in public places but implemented on 55” displays.

Other TV news

Some classic names of respect are using this fair to strengthen themselves in the American market. Westinghouse have launched a 3D TV but none of their sets came with Internet-enabled TV functionality. This was to keep their sets at an affordable price point.

RCA had rebuilt their name on a large run of TVs for the North American market as well as fielding a 55” Internet-enabled TV for the Latin-American market. They were using this show to launch some Android-powered mobile TV sets for the up-and-coming “Dyle” mobile / handheld terrestrial TV platform in North America.

Speaking of Dyle, Belkin and MCV were launching an array of equipment and accessories so that people can benefit from this mobile TV platform.

Home-theatre and Hi-Fi

Samsung had used this show to launch two soundbars with iPod / Galaxy S / Allshare (DLNA) integration with one being based on hybrid valve / digital amplification technology. They also ran with two Blu-Ray-based home-theatre-in-box setups with “Disc-Digital” which is Samsung’s implementation of the UltraViolet “digital video locker” service as well as the 7.1 channel unit being based on the above-mentioned valve-digital hybrid amplification technology. The other 5.1 channel version implements a wireless link for the back speakers and both systems use Wi-Fi to link to the home network.

Samsung even launched a home-theatre soundbar which can become two speakers and could link to sources via HDMI ARC (audio return path from HDMI 1.4-compliant TVs) or Bluetooth A2DP. RCA also launched a similar soundbar that connected to the home network and worked as a network media player for Netflix and similar services.

They are also implementing the “DIsc-Digital” UltraViolet implementation across the Blu-Ray player lineup at this year’s CES. One of the players is a similar size to a Discman and accepts discs through a slot while another of the players is a slimline form factor with HDMI inputs for TVs that don’t have enough HDMI sockets.

Sony have shown two Google-TV-based network video peripherals, the NSZ-GS7 which is a network media adaptor and the NSZ-GP9 which is a Blu-Ray player. As well, they have released two DLNA-capable Blu-Ray home theatre systems with full access to the Bravia Internet TV platform as well as a home-theatre receiver. Sony also released a few “HomeShare” DLNA speakers that connect to the Wi-Fi home network and have audio content pushed to them.

Panasonic have run with a large lineup of Blu-Ray players and Blu-Ray home-theatre systems. All of these connect to the home network and support DLNA functionality but the 3D-capable models and the home-theatre systems provide full access to Panasonic’s Viera Connect smart-TV platform including Skype and the Social Web for your existing TV.

These latest releases by Sony and Panasonic mean that you can use the cheaper and older TVs and have full access to the Internet-provisioned “smart TV” content and applications out there. In the case of the Panasonic 3D Blu-Ray players and home-theatres, add the Skype camera and you have just enabled a Skype-based video-conference setup,

Pioneer also used this show to launch the N-30 and N-50 audio-focused network media adaptors which work with DLNA 1.5 and Airplay network-media setups and the vTuner Internet-radio directory. They can handle 24-bit 192-kHz WAV or FLAC high-grade audio files and are Wi-Fi / Bluetooth ready with optional modules. The N-50 can also work as a high-grade digital-analogue converter for a CD player or MiniDisc deck.

Cameras

Samsung, Sony and Toshiba had launched cameras that were capable of uploading images to cloud-based photo-sharing services without the need for a computer. In the case of Sony, their Bloggie Live and Bloggie Sports cameras were being pitched as an alternative to the smartphone’s camera for Internet work.

Toshiba also exhibited a 3D camcorder with a built-in glasses-free 3D LCD screen so you can preview your 3D images properly. As well, Polaroid demonstrated a smartphone-style digital camera with a “proper” optical zoom lens – something that could be considered a bridge between a smartphone or digital camera.

Personal Lifestyle

Appliances

This show still hasn’t become a North-American showground for domestic appliances in a similar vein to the Internationaler Funkaustellung in Berlin. But LG was using this show to promote their “SmarThing” range of network-connected “white goods” which could be monitored from a computer.

Of course, Samsung also demonstrated a washing machine and clothes dryer that used a colour LCD touchscreen but was able to be controlled via an app on a smartphone. This means that you could track your washing from your phone’s screen.

Home Automation and Security

There has been some activity on this front mainly in the form of network-hardware vendors offering IP-enabled surveillance cameras, with TRENDNet offering a lineup of 12 units with varying features.

Other than that, the “Next Learning Thermostat” which learns your heating / cooling settings through the day was premiered at this show. Belkin also premiered the WeeMo home-automation system which is effectively an appliance-control module that responds to your smartphone.

Personal Health Care

There has been some more effort in developing online personal-health-care equipment which interacts with your smartphone or home network.

Withings, previously known for their Wi-Fi-connected bathroom scales, have released a baby scales which also links with the same network enablement and online health-monitoring setup as these bathroom scales. Similarly iHealth have released a wireless body-fat scales along with a wireless blood-pressure monitor and a “Smart GlucoMeter” glucose sensor for your iOS device. As well, FitBits released the Aria Wi-Fi Scale which is bathroom scales that link to your home network and measure weight, body-mass index and body-fat percentage.

IP Telephony

There has been some activity concerning voice and video Internet-based telephony. This is primarily with Skype being part of most of the “big-name” smart TVs and able to be added on to existing TVs through the use of this year’s Panasonic 3D Blu-Ray players and home-theatre systems. But Samsung also launched a Skype HD videophone unit for TVs and Biscotti launched a similar device for their own service.

RCA had demonstrated their voice-based IP telephony systems for business use while Ooma launched a cordless VoIP phone which has a colour LCD screen and can sync to Facebook for “picture caller-ID” images. $10 a month with the Ooma service provides for conferencing, second-line service and advanced call forwarding.

Tomorrow, in the last of the series, I will be talking about the network technologies that are to link these devices to the home network and the Internet.

Buyer’s Guide–Component Network Media Adaptors

Introduction

Western Digital WDTV Live network media adaptor

Western Digital WDTV Live network media adaptor

There was a trickle of component network media adaptors which provide media playback from the Internet or home network to an existing audio-video system but this trickle has now become a flood over the past few years with equipment being offered at varying functionality and cost points.

For video content, most of these devices including some of the current-model Blu-Ray players may offer “over-the-top” TV services to existing TV equipment and this may avoid the need to buy a “smart TV” for this kind of content. This would appeal to those of us who would rather spend money on equipping our home theatres with a video projector or top-notch high-performing LCD TV rather than buying a “smart TV” to keep up with the Joneses. Similarly, these devices can expose a secondary TV like the one located in the secondary lounge area or master bedroom to the plethora of online content.

Similarly, you may want to invest in an audio-based network media player so you can enjoy Internet radio or music held on the network-attached storage through the hi-fi system. This is becoming more so as high-grade audio files of classic and contemporary albums are being made available for sale and file-based audio content has now achieved hi-fi credentials.

What are these devices

A component network media adaptor like the Western Digital WDTV Live is designed to connect to existing audio and video equipment and show network-derived content on such equipment. Of course, they will work as a gateway to some Internet-hosted media services like IPTV / video-on-demand or Internet-radio services; and a few may work as a terminal for popular interactive Internet services like the Social Web.

If the manufacturer keeps investing in the device’s platform, there may be the ability for newer content services to be added to an existing device. This typically is being achieved through a continual firmware update or an app store that works in a similar vein to a mobile platform’s app store.

 

Sony BDP-S380 Network-enabled Blu-Ray player

Sony BDP-S380 Network-enabled Blu-Ray player

Some of these adaptor devices also have functionality for access to legacy media like a radio or TV broadcast tuner and/or an optical disk player. An example of this is the Sony BDP-S380 Blu-Ray player which I had reviewed. But these devices also have a USB port, iPod dock and / or memory card slot so that content held on any of these locations can be played through the device. Similarly, the Microsoft XBox 360 and the Sony PS3 games consoles are able to serve as component network media adaptors as well as satisfying marathon TV games sessions.

A selection of these devices have an integrated hard disk and are able to work also as a media server. Some of them may allow you to add the media files by “ripping” from supported optical discs or recording broadcast material from an integrated tuner as well as accepting the content from the network or USB memory keys in a similar vein to the typical network-attached storage device.

Two main classes

NAD C446 Media Tuner

NAD c446 Network Media Tuner

There are two main classes of these component devices and the class they fall in to is based on the content they are designed to reproduce.

Video-optimised

A video-optimised network media adaptor is designed primarily to reproduce video or still-image content on an attached TV or projector.

Key identifiers for this class of device include the presence of video connectors for a display device. These are typically HDMI, component or composite sockets alongside the audio sockets.

Another identifier is that there is a very small display on the unit itself which only shows content running time, or no display at all. The user is expected to operate the device using the remote control and looking at the attached video display device for visual feedback. This is common with very-low-end DVD players that don’t have a track/time display and I once saw one of these players in operation at a party and the hosts had the TV on so they know which tracks to play on a CD.

Of course, if they have a legacy media source, it will typically be something like a DVD/ Blu-Ray player or a digital-TV tuner. The online services available to this device would typically be the IPTV / video-on-demand / advanced-TV services and it may also work as a terminal for video-conferencing (with an add-on camera), interactive TV or the Social Web.

Audio-optimised

Linn Majik DS network preamplifier

Linn Majik DS network preamplifier

An audio-optimised network media device is designed primarily to reproduce audio content, especially music.

These devices have no video connections at all or they may use any such connections for a secondary purpose. It is augmented by the device having a display and controls on its front panel for selecting and playing content or a remote control with an LCD or OLED screen as its primary control surface. This means that the device won’t be dependent on the use of an external video display for its operation.

If the device supports legacy content, the will use either a radio broadcast tuner and / or a CD / SACD player. They will also have access to audio-based Internet content sources like one of the Internet-radio directories like vTuner, Pandora or Last.FM.

What to look for

Ethernet connectivity

A component network media adaptor should have an Ethernet connection in order to provide for reliable playback of high-quality network and online content via Ethernet or HomePlug AV. You may get away with Wi-Fi wireless for Internet radio, CD-quality audio content, still images or standard-definition video content.

UPnP AV / DLNA

As well, the device should support UPnP AV / DLNA functionality. The basic level of support for this functionality is to find and play media held on DLNA media servers using the device’s control surface. On the other hand, a better-equipped device is able to play content that you push to it from another UPnP AV / DLNA control point like a lot of smartphone media-control software such as TwonkyMobile.

It also allows your device to be future-proof and is of importance whenever you look towards running specialist media-server equipment such as network PVRs on your home network.

Internet-media services

Most low-end video-optimised equipment will support fewer Internet-video services but the mainstream-priced equipment from the big brands will offer access to the popular TV services in your territory like the catch-up-TV services and the big-time video-on-demand services like Netflix.

If a device has access to online interactive services like Facebook or Picasa, only one person will be able to operate their online service on the device at a time. This functionality may just be useful for showing pictures held on the user’s online-service account but activities like updating the status comment on the service or simply logging in may be very difficult. This is due to the limited user interface that these devices offer as I have previously talked about.

Devices complementing each other

Some of these network-media adaptor devices can complement each other. For example, you may use a newer adaptor that provides access to newer content services while you have an older adaptor that the manufacturers have given up on still able to provide some of the online and network-sourced media that you are after.

Similarly, you could use an audio-optimised network media adaptor for playing radio and music sources while you have an Internet-enabled TV or video-optimised network media player coming in handy for image and video content.

Conclusion

The component network-media adaptor, whether in the form of a Blu-Ray player, set-top box or network-enabled tuner, can expose existing audio-video equipment to the world of online or network-hosted entertainment content.

Now DLNA is officially part of the WiFi Direct personal network

WiFi Direct and DLNA get friendly, make streaming media a little bit easier — Engadget

My Comments

Just lately, the media-streaming use case has been brought to the WiFi Direct personal-area network as a competitor to the Bluetooth A2DP / AVRCP media-streaming applications.

There is an important fact that any WiFi-capable DLNA device could be a client device in this network setup as long as the host computer or smartphone is WiFi-Direct capable and running DLNA-compliant media management software. This could mean that your Intel WiDi laptop could be set to play video on that Samsung Smart TV or music on the Sony CMT-MX750Ni without needing to use an established WiFi router or access point.

What I see about WiFi Direct is that it is effectively being run as an alternative to Bluetooth for the personal-area network or standards-based peripheral link. But I am not sure whether it will succeed due to heavy emphasis by industry on the use of Bluetooth for this application and little consumer promotion of WiFi Direct capabilities.
