Why I value the UPnP AV / DLNA Home Media Network standards

If anyone is wanting to question why my blog is geared towards UPnP-based network management standards, especially the UPnP AV / DLNA Home Media Network standards, I am writing this piece to state what I am about.

I am not a spokesman for UPnP or DLNA or any of the companies that are behind these standards, but do place a high value on networks, network hardware and network media software supporting any of the UPnP AV / DLNA Home Media Network Standards. One of the main reasons I value these standards is that they work across any IP-standard subnet and allow hardware manufacturers and software developers to integrate the home media network in to their creations without reinventing the wheel.

Due to the nature of UPnP, the user doesn’t need to “run backwards and forwards” between devices to make sure devices are pointing to the correct network shares and that usernames and passwords are correct on both the client device and the server. This can become more of a headache for devices that don’t have the full QWERTY keyboard on them and require the user to use “SMS-style” or “pick-n-choose” text entry which can increase room for user frustration and mistakes. They also make the establishment of these multimedia networks as idiot-proof as possible, which would benefit home and small-business users where there isn’t a dedicated IT team available..

I also agree that a standards-based IT environment encourages hardware and software innovation as well as encouraging a “common-sense” approach to technology. It can also lead to these concepts being implemented in the most cost-effective manner, which makes the device affordable for most people, yet there is the ability to provide premium-grade equipment. This has led to hardware that is compliant with this standard becoming increasingly ubiquitous.

I know that Windows supports the standard through Windows Media Player 10 and has full “three-box” implementation in Windows Media Player 12 which is part of Windows 7. As well, I have noted that the open-source community have developed servers and similar software that can work with a Linux system. This feature is now considered “par for the course” for nearly all consumer and small-business network-attached storage units.

As well, the Microsoft XBox360 and the Sony PS3, which are considered “must-haves” as far as games consoles are concerned, have support for this technology. Samsung and Sony are also gradually implementing UPnP AV / DLNA in to their “main lounge area” televisions, with Sony nearly implementing the technology in to all television applications. Most of the big-time electronics manufacturers who have a line-up of home-theatre receivers have this feature in at least the high-end models, with some manufacturers pushing the feature in to the mid-range models. As well, nearly all Internet radios can play audio material held on DLNA-based media servers.

So the main reason I place a lot of value in the UPnP AV / DLNA Home Media Network is because of the ease that there is in establishing a heterogeneous multimedia network with products that suit what you want to do.

Smartphone Version of TwonkyMedia’s DLNA / UPnP Server Now Available | eHomeUpgrade

 Smartphone Version of TwonkyMedia’s DLNA / UPnP Server Now Available | eHomeUpgrade

Now the Android platform is moving closer to the DLNA Home Media Network. Other platforms like the Symbian S60 (Nokia N-Series) and the Apple iPhone have had software solutions that expose content held on their storage location to the DLNA Home Media Network, either as native software in the case of the Symbian S60 platform or as an “app” available through the platform’s usual software resources.

This implementation is very similar to TwonkyMedia Server in that it doesn’t have a “media controller” which could allow the user to “push” media to a “MediaRenderer” device like one of the Sony BRAVIA TVs.  It may come about if TwonkyMediia port the TwonkyMedia Manager program or a developer ports one of the iPhone DLNA controller apps to the Android platform.

It will be interesting to see who will come through with a media controller which will become more realistic with the Android smartphone and MID platform.

Ethernet AV – What could it mean for the home media network?

 Will home networks bank on Ethernet?

One of the next points of research that will be appearing for the home network is “Ethernet AV” or “AV-optimised networking”. The main goal with this research is to deliver time-sensitive content like music or video over an Ethernet-based network so it appears at each endpoint at the same time with the bare minimum of jitter or latency.

This research is being pitched at any application where a data network may be used to transport AV information. In the home, this could include multi-room installations where the same programme may be available in different rooms or multi-channel setups where a Cat5 Ethernet, Wi-Fi or HomePlug network link may be used to distribute sound to the rear-channel speakers. In a vehicle or boat, the Cat5 Ethernet cable could be used as an alternative to analogue preamp-level or speaker-level cable runs to distribute audio signals to the back of the vehicle or through the craft. The same method of moving AV signals can appeal to live-audio setups as the digital equivalent of the “snake” – a large multi-core cable used to run audio signals between the stage and the mixing desk that is located at the back of the audience. It can also appeal to the use of IP networks as the backbone for broadcast applications, whether to deliver the signal to an endpoint installed in a home network like an Internet radio or IPTV set-top box; or to work as a backbone between the broadcast studios and multiple outputs like terrestrial radio/TV transmitters and/or cable/satellite services.

The main object of the research is to establish a “master clock” for each logical AV broadcast streams within the home network that represents a piece of programme material. This then allows the endpoints (displays, speakers) to receive the same signal packets at the same time no matter how many bridges or switches the packets travel between the source and themselves.

Once this goal is achieved at the Ethernet level of the OSI stack, it could permit one to implement software in a router to provide Internet broadcast synchronisation for endpoints in a logical network pointing to the same stream. This means that if, in the case of Internet radio, there are two or more Internet-radio devices pointing to one Internet broadcast stream, they appear to receive the stream in sync even if one of the devices is on the wireless segment and another is on the Cat5 Ethernet segment.

This issue will need to be resolved in conjunction with the quality-of-service issue so that time-sensitive VoIP and audio/video applications can have priority over “best-effort” bulk data applications like e-mail and file transfer. Similarly, the UPnP AV / DLNA standards need to implement a quality-of-service differentiation mechanism for bulk transfer compared to media playback because there is the idea of implementing these standards to permit media-file transfer applications like multi-location media-library synchronisation and portable-device-to-master-library media transfer. Here, bulk transfer can simply be based on simple “best-effort” file practices while the time-critical media synchronisation can take place using higher QoS setups.

The other issue that may need to be resolved over the years is the issue of assuring quality-of-service and AV synchronisation over “last-mile” networks like DOCSIS cable, ADSL and FTTH so that IP broadcasting can be in a similar manner to classic RF-based broadcasting technologies. This also includes using the cost-effective “last-mile” technologies for studio-transmitter backbone applications, especially if the idea is to serve “infill” transmitters that cover dead spots in a broadcaster’s coverage area or to feed small cable-TV networks.

Once these issues are sorted out, then the reality of using an IP network for transmitting media files can be achieved.

The rise of the “multimedia router”

Links

New multimedia router up before FCC – clock radio (FM+Internet), access to online video services, media playback from local storage – http://www.engadget.com/2009/12/09/qisda-sourced-multimedia-router-hits-the-fcc/

D-Link DIR-685 router with electronic picture frame – http://www.dlink.com.au/Products.aspx?Sec=1&Sub1=2&Sub2=5&PID=388

My comments on this new device class

What we are starting to see is the arrival of the “multimedia router” which is a device that is primarily targeted at the home and small-office user, the people whom this blog is written for.

What is this product class

This product class is a single-band Wireless-N broadband (Ethernet WAN) router with integrated multimedia playback functionality through an integrated screen and / or speakers. They have access to the popular online multimedia services and are able to play media held on local storage.

The screen in some of the devices also acts as a local “instrument panel” for these routers and if the device has a touchscreen, it could permit the device to have a local control panel.

They have come about because the cost of integrating these functions in the one shell has become very cheap and it has allowed manufacturers to differentiate their product range in a deeper manner.

Could this product class have a place in the broadband-router market

These devices may appeal initially as a novelty device but they could add an independent media playback device in the location where the Internet router would also go. This would typically be the home office or study or the back office of a small shop. In households where the phone is customarily installed in the kitchen or hallway, it could be feasible to make maximum benefit of these locations by locating these routers there alongside an Ethernet-ended DSL modem because these units could provide a picture display or “there-and-then” information display and, in the case of the proposed design, Internet radio in one box.

Similarly, even if another router like a VPN-endpoint router is on the network edge, these units can work as an integrated multifunction wireless access point that can be moved around the house.

What the device class needs

The first two iterations of this device class need to support DLNA-compliant LAN media playback so that media held on NAS boxes and media server devices that exist on the local network can be played through these devices. They could support DLNA MediaRenderer functionality as a controlled device so a PC or other device can become the control point.

They would also have to work well as an access point or as a router with a simple configuration routine for units that are connected to existing routers. They could support working as dual-band single-radio or dual-band dual-radio access points for those networks where a dual-band 802.11n segment exists.

These kind of features could be introduced in to this device class as more manufacturers introduce devices in to the class and the competition heats up. The previously-mentioned DLNA functionality could come in to play through a firmware update during the existing router’s service life.

Conclusion

Once this device class is developed further, it could be the arrival of a router that can acceptable be on show in that credenza in the home office.

Product Review – Pure Evoke Flow portable Internet radio (Frontier Internet Radio Platform)

Pure Evoke Flow This radio that I am reviewing is the top-end network-enabled model of Pure’s popular Evoke series of DAB digital portable radios. All of the models have different functionality but a very similar style, with an oval-shaped accent encompassing the speaker and control area. The lower-end units have a wood cabinet and a plastic front panel which is varied according to the model.

Description

This particular unit has a gloss-black finish with a large yellow OEL bit-map display and knobs for the volume and tuning controls. Other functions are operated using touch buttons that are lit up in yellow where applicable. This is intended to make the set look more classy, especially with the “piano-black” finish.

OEL display on Pure Evoke Flow The OEL or “organic electroluminescent” display is based upon the displayed letters and segments needing the power to light up rather than the LCD display being dependent on a backlight to be easily visible. This is similar to what is used on my Nokia N85 phone reviewed in the blog and is very appropriate as a display method for devices that work on low power. I even refer to the OEL display as the “vacuum fluorescent display” for battery-operated devices because of the fact that the display yields the same brightness and contrast as the typical self-illuminating vacuum fluorescent display often used as a user-information display on VCRs, DVD players, home theatre receivers and similar equipment but doesn’t chew through the batteries to achieve that aim.

The Evoke Flow, like the rest of the Pure Evoke range of radios, is capable of operating as a two-piece stereo set when you purchase and use the optional matching external speaker. Similarly, this radio, like the rest of the Evoke range, can be used as a battery-powered portable radio when you buy a Pure rechargeable battery pack from the same retailer that you bought the set. These accessories haven’t come with my review sample, so I won’t be able to assess how it works with these accessories.

Features

As well as its Internet-radio and network media player functionality, this set is also capable of receiving DAB+ digital radio and FM radio with RDS RadioText.

For connectivity, it also has a 3.5mm auxiliary input jack for playing music from an iPod or portable CD player and a 3.5mm line-out jack for use with external amplifiers or recording devices. There is also a 3.5mm headphone socket as well as the socket for the accessory stereo speaker. All these connections are located on the back of the set, in a similar manner to the Kogan and Revo Internet radios reviewed in this blog. I have always preferred these sets to have the headphone jack located on the front panel of the set, or at least on the side, to permit “walk-up” headphone use where you didn’t have to move the set to plug in a pair of headphones which are used on an ad-hoc basis. This is a practice I have often seen with most portable audio equipment I have seen and used through the 1970s and 1980s.

Pure do supply an iPod dock as an optional accessory for this radio but it doesn’t have a power input connector so the iPod can be run on external power while playing through the radio. Instead, I would use the Apple Universal Dock or an iPod dock with a USB, Apple Dock or DC socket so that I can connect an external power supply to the iPod or iPhone that is in the dock.

The set can connect to the home network and the Internet via a 802.11g WiFi network segment but this network can be secured to WEP, WPA-PSK or WPA2-Personal standards. This is the same for other Internet radios, which also means it can’t log in to a “corporate-standard” WPA(2)-Enterprise network or a wireless hotspot that uses Web-based authentication.

An improvement I would like to see on the setup when it comes to enrolling the set with a WiFi network would be to allow it to keep configuration details for multiple networks. This is more so because this radio is an easily-portable design and capable of working on batteries. thus could be taken between locations at a moment’s notice.

It can also stream audio from DLNA-compliant media servers like TwonkyMedia Manager or Windows Media Player (Windows Media Connect) or most NAS units.

The unit has the built-in Internet radio directory but benefits more if you associate it to the Pure Lounge portal. Here you benefit from facilities like persistent Internet radio presets and extra content. The Lounge service also provides background sound-effect loops like waves for situations where a sound-effect loop is needed. Such applications may include having the sound of waves to help you drift off to sleep or the sound of thunderstorms to help in getting a dog used to thunderclaps. This also includes a reference tone set representing the strings of a guitar for use when tuning your guitar.

Use

When you use the Internet radio, you can browse a worldwide directory of all the stations registered with Pure’s Internet-radio directory or use a “form-based” search to narrow down the list. Here, when you touch the “Search” option, you see a form and select the attribute to filter the list by. This can be by “Genre”, “Country”, “Availability”, and “Bit Rate”. Then you press the Tuning knob to set the attribute’s value. After that, you touch the “Go” option to see your reduced selection. This is different to the Kogan and Revo radios where you went through a menu tree to select the Internet-radio station that you want.

Unlike the Kogan and Revo radios, there isn’t a row of preset buttons for allocating favourite stations. Instead, you select the “Favourite stations” which is marked with a heart symbol to go to your preset list and browse through the preset list and press the Tuning knob to play that station. When you listen to a station that you want to add to the list, you touch the “Add to Favourites” option to set it in your preset list.

The set can work as a DLNA music player but you can only play the content by using the set’s controls rather than over the network using software like TwonkyMedia Manager.

FM tuning is based on a “seek by default” method so that when you turn the knob, the radio finds the next strongest signal. The DAB function is based on selecting from a list of stations sorted by alphabetic order. There is a “trim station list” option for clearing up dead station entries, which is handy if you move the set between cities or the DAB multiplexes are being reorganised.

Sound and Useability

The set sounds more “soft and rich” compared to most small portable radios, including the Kogan and the Revo, but has a similar sound output level. Like the other Internet radios I have reviewed, there isn’t a tone control, whether as an easily accessible control or within the menus.

The OLED display is much more legible than the typical LCD display found on most Internet radios and is a bit too bright for night-time use. There is the option to dim the display or to have the display dark whenever the set is turned off. The clock display is large enough for easy reading across a room. Even if you dim the display, it is still legible, which can be a bonus if you have the set in your bedroom as a clock radio or have it in a hall or other room and still like the clock display to work as a “nightlight”.

Fit and finish

The set’s fit and finish represent a high-quality product that is enjoyable to use. The knobs even have a feel associated with you operating a piece of quality equipment. The main limitation with the black gloss finish is that it could harbour fingermarks too easily and you may have to wipe those off frequently.

The telescopic aerial that you need to use for FM or DAB reception is much different from what I have seen in use on most portable radios that I have used. Here, this set, like a National Panasonic RX-C52 “ghetto blaster” that I have had once,  has a dedicated screw for anchoring the aerial. This will definitely make it easier the user to buy and fit a replacement aerial if this aerial is damaged, as is common with a lot of portable radios that I have seen and used. Good marks to Pure for realising what often happens with many portable radios and making the aerial easy to replace on their Evoke radios.

Points of improvement

The Pure Evoke Flow isn’t a perfect portable digital / Internet radio and needs a few points of improvement for its product class. One would be for Pure to release a cheaper “junior model” in the “Evoke Flow” line that has a finish similar to the rest of the Evoke series and uses a two-line alphanumeric display rather than a bitmap display.

As far as connectivity is concerned, I would at least like to see the headphone socket located up front or on the side to allow “walk-up” headphone use. For battery use, there could be the possibility of the set working on any of the “regular battery sizes” i.e. AA, C or D through the use of an add-on battery module that takes these batteries, so that one can use these commonly-available “Duracell” or “Energizer” batteries with the radio.

The wireless-network connectivity could be improved through support for WPS “quick-setup” and / or the ability to work with multiple networks to suit its nature as a portable radio. The set could provide information that is necessary for enrolment to the “Lounge” portal on the display through a set-up option.

Conclusion

The set’s “piano-black” look will appeal to people who like a “classy look” for their Internet radio solution. This would typically encompass a lot of office users, especially professionals. It may also look the part with a home office or on a shelf in that classy kitchen. But it can definitely work very well as a “floater” portable Internet radio that can be taken around the house as required because of the light size and integrated handle. The fact that the handle doubles as a snooze bar may make the set appeal as a clock radio, although you have to descend through menus to set or enable the alarm clock, sleep timer or countdown timer.

The set’s display would be suitable for people with limited eyesight and the fact that you use knobs to adjust the volume and select stations may make the set appeal to mature and older users who are more comfortable with using knobs to select stations or adjust the sound.

The main limitation with this set is that it is significently expensive, usually around AUD$400-600 depending on the retailer.

Rovi brings the car closer to the DLNA home media network

News articles

Rovi Home Network Media Syncing Automotive Solution Announced | eHomeUpgrade

Rovi hooks cars up to home media collection | TechRadar (UK)

From the horse’s mouth

Rovi’s own page about their automotive network solutions

My comments on this topic

Mustang dashboard with Eclipse head unit What Rovi is doing is integrating the vehicle in to the home network and its content pool. This will, as far as car entertainment companies are concerned, legitimise the feasibility of a hard disk / solid-state drive and/or WiFi network connection in the car AV system.

Key features

Content-description metadata would be available for CDs, DVDs and Blu-Ray discs in a manner similar to the current practice with iTunes or Windows Media Player. This can also work well with setups that have a built-in hard disk and a “rip-to-hard-disk” function for CDs. This can be updated with new data over the network connection or with the user transferring data from their PC using removeable media.

There would also be the ability to have improved content lookup available for applications where the media is stored as files in a file system like in an SD card, USB memory key, mobile phone or MP3 player like the Apple iPod.

Another key feature that Rovi has established in the press collateral has been the concept of transferring and syncing media content between the vehicle and a media collection hosted on a DLNA media server. This again would work with a 2.5” hard disk that is located in the car and used as the data storage.

There is even the concept of sharing data held in the vehicle or devices plugged in to the vehicle with associated networks which could allow for such things as map updating for satellite navigation and, I may have said this before, collection of diagnostic information from the vehicle.

Where do I think this will exist

The concept will typically appear initially as equipment installed at the factory in high-end cars and / or as high-end aftermarket car AV equipment that appeal to young men who turn their highly-customsied cars into “mobile discos”.Also these kind of markets are based around people who are usually more willing to spend big on the new technologies.

The primary form factor for aftermarket deployment may typically be in the form of the 2-DIN car navigation/audio/video head-unit with a large touchscreen on the front. It is because these head-units will typically have room for an integrated hard disk alongside a CD drive.

Some manufacturers may move towards moving the hard disk out of the head unit so as to reduce costs or design equipment that fits in to a 1-DIN car accessory space. This will typically allow for a USB or eSATA hard disk in an enclosure with an automotive-rated power supply located somewhere in the dash. On the other hand, highly-compact SSDs could become part of 1-DIN head-units which become part of the home network.

The network connectivity issue may be worked out either with an integrated WiFi-Bluetooth radio platform in the head unit or a WiFi network adaptor on the end of a USB cable or WiFi-Ethernet bridge on the end of an Ethernet cable located near the windscreen (windshield) or the rear window.

Conclusion

Once Rovi have established this technology, it could mean that the car will exist as part of the home entertainment and information network.

Windows 7 – What does it mean for multimedia and the home media network

Improved sound-reproduction infrastructure

Some of you may use two or more sound cards in your computer; such as using the sound circuitry that is part of your motherboad as well as an aftermarket sound card. Windows 7 caters for that by allowing you to relegate a particular sound subsystem to a particular program or activity. A common use would be to use a Bluetooth headset for Skype and related VoIP communications, gaming taunts and similar applications while you have your music playing through the main speakers. Similar you could connect a “good” sound card to a good sound system for recording and playback while the onboard sound infrastructure can be used for system sounds.

Even the ability to send digital audio signals to home-theatre equipment via the HDMI port has been improved. It includes the ability to pass the high-definition audio streams from BluRay and similar applications as a raw bitstream. It will also provide the multiple-sound-device functionality as mentioned previously with HDMI audio setups that use a dedicated sound infrastructure rather than feeding an SP-DIF audio bitstream from the computer’s main sound card.

As well, there is functionality that permits the music or video sound to be reduced in volume whenever a VoIP or similar call comes in even if the call goes through a different sound device, which makes life easier when you take these calls using the computer.

DirectX and Gaming

DirectX in Windows 7 has been taken up to version 11 and this has brought forward a lot of improvements as far as computer games go. This also includes a lot of work “under the bonnet” to improve game responsiveness with the screen and sound and bring up PC gaming to current-generation console level.s

Streamlined network management

The network management functions are similar to what Windows Vista users have expected in the Network And Sharing Center, But this interface has been streamlined and made easier to use. The “full map” is still available and you can gain access to shared resources or UPnP-provided device management pages when you click on the various devices.

HomeGroup

This feature is a way of establishing a “circle of trust” within a home network when it comes to sharing resources around that network. This is based on a computer-generated password that is used across the HomeGroup to authenticate all of the computers on the network to the resource pool. At the moment, this only works across Windows 7 boxes on the network, but it may be worth keeping an eye out for Microsoft and third-party downloads that allow Windows 2000 / XP / Vista, Macintosh and Linux boxes to work in with a HomeGroup setup.

This is another way that Microsoft implemented a practice commonly associated with locks and keys, Here, the identifying factor that only allows the lock to work with particular keys is already determined by the tumblers that are integrated in the lock’s mechanism and these tumblers are configured to work that way either by the manufacturer or by a locksmith when you have the lock rekeyed.

The first instance of this was with Windows Connect Now, which was implemented in Windows XP Service Pack 2 as a way of configuring a highly-secure wireless network. Here, the WPA-PSK passphrase was determined randomly by Windows Connect Now and used as part of a “configuration manifest” file to be transferred to routers and other computers using a USB memory key. This was extended to Windows Vista through the WPA-PSK passphrase being uploaded to a compliant wireless router using an Ethernet connection, and was integrated in to Wireless Protected Setup which is implemented as part of Windows Vista Service Pack 2.

Another advantage provided with HomeGroup is that it can work with “work-home” laptops that move between a domain-managed business network and a home network. HomeGroup can also cater for other small networks, because there is the option to share particular resources with particular users as you were able to do son with any Windows-based CIFS network.

Improved DLNA support

Windows Media Player 12, which is part of the Windows 7 distribution or, in some cases, available as a free download from Microsoft, has DLNA built in to its ecosystem. This doesn’t just stop at sharing media files with DLNA / UPnP AV media devices or streaming media files from other DLNA / UPnP AV media servers like NAS boxes. It allows you to “push” content to DLNA / UPnP AV media devices that present themselves as “MediaRenderer” devices. This is typically provided in the form of the “Play To” right-click shortcut for multimedia files.

Remote Media Streaming

You can stream content from one Windows 7 computer to another over the Internet as long as you use the same identifier, like a Windows Live ID. with each of them. This can be useful for situations like temporary accommodation like hotels, holiday homes or serviced apartments where you may have your computer at home running and you may want to play media at your temporary location. I have discussed this feature before on this blog and have raised issues regarding VPN operation and the computer that is pulling the media being able to serve it to DLNA-compliant media hardware on its local network.

Inherent support for current digital-TV standards and Internet TV

Windows 7 provides its Media Center application with inherent operating-system support for currently-deployed digital-TV standards so there isn’t much need for TV tuner card manufacturers to supply software to work with the current standards. As well, this operating system provides improved support for “over-the-top” Internet TV services that may be released in your country. In some cases, this may do away with the need for the coaxial TV cable to the computer or the need to sign up to cable services full of “fodder channels” to gain access to the “good channels”.

Next article in the series will touch on how Windows 7 will benefit the small business and the work-home laptop.

Product Review – Kogan Wi-Fi Internet Table Radio with iPod Dock (Frontier Internet Radio Platform)

Overview

Kogan Internet radio

Kogan is an Australia company who are selling good-quality value-priced consumer electronics like LCD TVs in a manner that is considered common in the USA but rare in Australia. It is to sell the goods under their own brand through what used to be known as mail-order. You can buy equipment like this Internet table radio by visiting their Website or calling 1300 304 292.

The set, which is sold direct for $169 excluding delivery but including Australian GST, looks like a mantel radio made during the late 70s just before that style of radio went out of fashion and has a generous-sized front-facing speaker behind a mesh grille. An iPod or a USB memory stick can be connected to sockets installed on the top of the set.

The set is powered from the mains through a small AC adaptor but the adaptor that came with the review sample had something that can be annoying if you were to properly switch it on or off at the wall, because it sticks upwards.

Connectivity

The set has an iPod dock which can work with most of the Apple iPod range; and a USB port for connecting USB memory keys, MP3 players and other devices that present themselves as USB Mass-Storage Devices. This port may be better placed on the front or back of the radio so as to avoid dust, crumbs and other nasties falling in to the set and causing unreliable operation with USB devices.

It also has a 3.5mm jack for connecting up another MP3 player, Discman or similar device to play through the built-in speaker; and has a 3.5mm headphone jack which can also be used to play the set through a pair of better-sounding active speakers.

Setup

When you unpack the set, you don’t get the instruction manual as part of the packaging. Instead, you have to go to the support section of Kogan’s web site to download the manual as a PDF file.Kogan Internet radio - close-up

There are some issues that affect the way you integrate the radio to the Wi-Fi home network. One is that there needs to be a clear indication for “enter” to confirm the WPA-PSK key and another clear indication for “backspace delete” of erroneous characters.

As well, you have to make sure that your router’s wireless-network security is working in a “pure” WEP or WPA-PSK mode rather than a “compatibility mode” that may be common on some routers made when WPA just started to come in as a Wi-Fi link-level security option.

Once the radio is on the home network, everything is effectively “plain sailing”. The unit can be set up to get the time from the Internet, but you have to determine the time zone yourself by going to the Main Menu – System Settings – Clock Settings option. You will also have to change the time zone by an hour every time we switch from standard time to daylight-saving time. For example, in Sydney and Melbourne, you would have to set the Time Zone to +10 during Standard Time and to +11 during Summer Time. This may be rectified in a future firmware update for this set.

As far as the DAB (digital radio) operation goes, there isn’t a “clean-up and scan” routine available. Typically you have to do the “full scan” routine which adds new stations to the multiplex roster. This was annoying because the review sample, like the Revo iBlik RS clock radio reviewed in a separate review, had come down from Sydney and had references to the Sydney DAB multiplexes and stations. It can also be a headache for those of us who move between towns, or if there is a situation where the DAB multiplexes are being re-organised.

Use

The menus on the set are mainly navigated through the use of the tuning control which you turn to select the option and press to confirm the selection. There is a “Back” button to go back through the menus if you need to do so. The volume is adjusted with a smaller knob rather than “up-down” buttons. You change between FM, DAB, Internet Radio, Media Player, USB, iPod and Aux modes by pressing a MODE button. This control arrangement  makes the set appeal to be easier and comfortable for older people to use and makes you think of it as a proper radio.

Access to Internet radio stations is through an integrated directory that is regularly updated. You can select stations by “home area”, “country” or genre. I did a test to find Heart 106.2 London, a radio station that I often listen to over the Internet. Here, I went to “all stations”, then “country”, then “Europe”, then “United Kingdom” to filter for UK radio stations. After that, I went to all stations and browsed the list of UK stations to find “Heart London”.

There are five preset buttons which you can assign to a station in each of the radio modes. This means you have 5 FM stations, 5 DAB stations and 5 Internet radio stations held as “one-touch” presets You associate the button with the currently-playing station in the same manner as most car radios that are currently in use i.e.: hold the button for around 10 seconds until the display shows that the station is with the preset.

The radio also works well as a DLNA network audio player with the ability to honour the UPnP AV Media Server’s media hierarchy. It even worked well with playing music hosted on my computer by allowing a smooth playout experience. One main problem was that the transport keys such as the play-pause button didn’t work for the network media stream.

The radio does work well as an iPod speaker dock and the function keys worked properly when navigating the iPod’s content. I also attempted to adjust the volume from the iPod, but the sound came through at the same level, thus requiring you to use the radio’s volume control to adjust the sound.

Sound quality

The sound was something typical of either a classic mantel radio or one of those mono radio-cassette recorders made during the 1970s. There isn’t any way to adjust the tone on the set, whether through the menus or a separate control. There is still some “punchiness” in the sound but not the full bass expected by today’s young generation. A difficult-to-reproduce piece like the BBC brass-band rendition of “God Save The Queen” played at the end of the day (UK time) on Radio 4 may sound “difficult” at times. For talk-radio broadcasts, the sound is clear and intelligible whether turned up loud or at a modest listening level.

The sound volume is relatively loud, thus allowing the set to fill a room with its sound and can compete with a noisy appliance operated nearby. I even ran our noisy rangehood fan while the set was playing and it could easily compete with that. This means that it could work well at “belting out the tunes” in a takeaway-food shop, café or similar establishment.

Fit and finish

I have observed that this unit has avoided fingermark-attractive “gloss” finishes but this may be considered as a set that is dull and boring. But this also has been a bonus with a review unit that has “done the rounds” and been handled by many reviewers. This would be a bonus for radios that are likely to be handled by many users or spend their working life in a kitchen.

When I bought my own one of these sets, I had it working as a “utility radio” for the household and at times had seen it used in a workshop and outdoors while there was carpentry work going on. This hasn’t had any impact on the set’s finish or operation.

Points of improvement and product-class development

Connectivity improvements

The 3.5mm headphone jack could be positioned up front so as to allow “walk-up” headphone use and could be set to override a 3.5mm external-output jack on the back as well as the built-in speaker. The role of this rear-mounted jack could be determined by a menu option as a “line-out” jack independent of the volume control and headphone jack or an “external speaker” jack that is dependent on the volume control that can be set to either run with or override the internal speaker. This would allow Kogan to supply a “right-channel” active speaker as an accessory thus causing the radio to become a 2-piece stereo radio.

The manufacturers could relocate the USB port to the front of the set thus removing the risk of problems associated with dust and foreign objects falling in to the top-mounted USB socket.

Improved display

The display could be improved as far as legibility goes. It could be a high-contrast LCD with a strong LED-array backlight. Some other reviewers wanted to see a variable backlight display, which could make the set fit for use in a bedroom. This would be best executed with a backlight setting for standby use and a setting for whenever the set is in operation.

Possibility of tone control

There could be the possibility of some form of tone control, not just as a “bass-boost” option. This could be in the form of the classic “tone” control knob used on older sets which provided a bass-rich sound at the low setting and a bright treble-rich sound at the high setting.

WiFi connectivity improvements

Some users may take one of these sets between multiple locations like home and work or home and a friend’s house or holiday home; as I have often seen with some clock radios and portable radios. An improvement that I would like to see would be to allow the user to have up to eight “network profiles” stored in the radio, like what happens with computers and mobile phones. There could be an SSID and WEP/WPA passphrase associated with each of the profiles so the set doesn’t have to be reconfigured when it is taken between regular locations.

Similarly the set could support WPS “quick-connect” options so as to avoid messing with “pick-and-choose” WPA passphrase entry.

Conclusion and Best Placing

This set would be best suited as a radio you may use in a small office, household kitchen, small shop or waiting room at a doctor’s or lawyer’s office. It is also a set worth considering for the workshop or garage even though it is as loud is most typical clock radios because of the fact its finish isn’t susceptible to these working environments. It wouldn’t be appropriate in the bedroom as a replacement for that old clock radio because the set would be too big for a bedside table, the display is too bright even when switched off and the alarm-clock functionality isn’t easily accessible.

I also applaud Kogan for providing a tabletop Internet radio that is positioned at a price that most people can afford and this could be a way for them to cut in to the premium table radio scene. They could go further with a unit that has two speakers, a portable DAB+/Internet radio that can run on batteries or AC, or a tuner that can pick up FM, DAB+ and Internet radio; with all these sets being capable of playing audio from DLNA Home Media Networks.

But I would still recommend the Kogan Wi-Fi Digital Radio with iPod Dock as a value-priced entry-level DAB/Internet radio for situations such as your first Internet radio or when giving someone an Internet radio as a gift. It may also be a good excuse to ditch that tired old radio in the kitchen or office for something that offers a lot more.

Product Review – Revo iBlik RadioStation Internet clock radio (Frontier Internet Radio Platform)

Revo iBlik RS 1 I am reviewing the Revo iBlik RadioStation Internet clock radio which can work as a speaker dock for the iPod. As well Marks & Spencers, the British department store commonly known as “Marks & Sparks”, sell the same radio under their private label but without DAB digital radio as the M&S Internet Radio with iPod Dock.

Overview

This radio looks like one of the classic clock radios sold through the 1970s and 1980s but, instead of being a flat box with the faux wood-grain finish, it has a trapezoid look that is finished in dark charcoal grey. The top of the radio has a random-styled speaker grille and a removeable panel where you dock an Apple iPod or iPhone, and the right had side of the top surface has all of the radio’s control buttons. The front of the radio has a darker middle stripe with the LCD display. The set uses a telescopic aerial (antenna) rather than the ordinary “pigtail” aerial wire that is common with clock radios for FM and DAB operation. The only limitation, which is common with most portable radios, is that you can’t replace a broken telescopic aerial yourself. The Wi-Fi aerial is totally integrated in to the set.

2009-11-07 001 When the unit is turned off, the display is just bright enough to be a nightlight, which makes it suitable for bedroom use. The display becomes significantly bright when the set is in operation, but there could be improvements in the contrast issue. Revo could have improved the display by using a fully-bitmapped display which can allow for a full-height time display which would be more appropriate for this class of radio than a two-line date and time display.

The set comes with a slim remote control which can be a bonus if you need to operate it from the other side of the room. The only problem with this was that you had to be relatively close to the set to operate the remote control. This may be a problem with the review sample that had “done the rounds” and the remote control’s battery was nearly exhausted and had been transported with the battery in place.

Connectivity

The set has a 3.5nn line input jack (referred to as an mPort jack) for use with portable CD players and the like as well as a pair of RCA line-out connectors on the back for use when connecting to an external sound system or a recording device.This connection is a boon to small businesses who may want to connect the radio to a music-on-hold setup or public-address system if they want to play DAB, Internet radio or music held on a computer over the network through these devices.

Setup

This set is set up in a manner similar to other Frontier-based radios like the Kogan reviewed elsewhere in the blog. <Hyperlink to Kogan review> There is still that niggle with the confusing arrow and “return” symbol when you enter your wireless network’s passphrase. As well, you need to make sure your router isn’t using a WEP-WPA compatibility mode because the set may not connect to the wireless network.

The radio has the option of obtaining the time from the Internet or the local DAB multiplex so it sets itself to the correct time. If you set it to refer to the Internet, you then determine your local time zone. It also has a dedicated “DST” option which you turn on when the clocks go forward for Daylight-Saving time and turn off when the clocks go back for regular time. This is unlike the Kogan where you have to advance the time zone by an hour when the clocks go forward.

The DAB function doesn’t have a “clean-up and scan” option for situations where your set may be moved between locations or if the local DAB multiplexes are re-arranged. This was more of a problem with this review sample which had been taken between Sydney and Melbourne.

Use

Revo iBlik RadioStation - control panel You navigate the menus using four “arrow keys” and a “select” button in the centre of those keys. They are also used to tune the radio amongst the FM, DAB or Internet stations. There is a “mode” button to change between the different sources such as the Internet radio, DLNA music player, DAB radio, FM radio, iPod or aux inputs.

The set can store 10 preset stations in each of the FM, DAB or Internet-radio “bands”, which can be an asset if you dabble in many of the Internet-radio stations. This radio also works as a DLNA media player but can only support control from the set’s control panel or remote control.

Suitability for the bedside table

To set the alarm clock, you press the ALARM key. Here you have room for four different alarm times that can be set to apply once only, every day, Monday-Friday or Saturday-Sunday. This could be useful for setting an earlier wakeup time for the work week and a later time for the weekend where you can afford to have that sleep-in; and you can even have a different wake time for him and her on both the work week and the weekend.

You can set the unit to wake you to the buzzer; a particular station on either FM, DAB or Internet radio; or music held on an attached iPod at a chosen volume. What you set the radio to wake you to can be different for each alarm event, so you can factor in different radio programs that are broadcasting on different times. This definitely offers more than the typical clock radio that most of us use where you have up to two different events and you can wake either to the buzzer or the last-tuned radio station.

When you set the alarm, you have to make sure you save the changes by highlighting the “Save” option and pressing SELECT. This is also true if you want to override the alarm clock by turning it off. The ability to set the alarm clock to come on to a nominated radio program allows you to sleep to music from your iPod, DLNA network media server or a different radio station while you wake to your favourite radio program.

The all-important snooze bar is located at the front edge of the control buttons and is bracketed by two other buttons which are radio presets or “previous-next” buttons when the set works as a media player or with an iPod. This same button can be used to set up the sleep timer. Here, you press this button repeatedly to determine how long the radio can play before switching itself off, then press the “select” button to engage the sleep timer whereupon the radio will turn itself off after the nominated time.

Sound quality

The sound quality is similar to what you would expect for a typical 1980s-issue clock radio. This is because it uses the same speaker size as these units and the speaker is positioned to come out the top of the set in the same manner.

Fit and finish

The finish is a “satin-style” plastic finish that is similar to most current-issue clock radios and portable radios. This hasn’t harboured unnecessary fingermarks and the buttons are quick and responsive. It does then have the look and feel of a good-quality clock radio.

Points of Improvement

For this class of radio, the main point of improvement would be a larger bitmapped display with an EL backlight or a larger bitmapped OEL display which can show the time in large figures which makes it suitable for viewing from a distance. Other than that, the radio suits its best-placing very well, as a clock radio for the bedroom.

There could be an option to have the alarm set for particular days of the week, such as Monday, Saturday or Sunday; as well as Monday-Friday and Saturday-Sunday so you can cater for situations where you may have to factor in particular shifts that occur on particular days.

Conclusion and Best Placing

This is an Internet radio / iPod dock / network music player that I would recommend for use in the bedroom as a highly-flexible alternative to that old clock radio. This is more so if you want to wake up to more than regular FM and AM radio or need something that provides a highly-flexible alarm clock. It can also be used in the office, kitchen, shop or waiting room as a radio or background-music device, and can become a conversation piece in itself because of its shape. 

If you are after this radio in Australia, from my experience, I have found it for sale at the electrical department of the David Jones department stores at Westfield Shoppingtown Doncaster. You may also find it available in other premium department stores like Marks & Spencers.

I have had this set on loan for a week courtesy of Bush Australia. As well, Bush Australia have offered the set for sale to me at a reduced price as per their standard practice with media.

Buyer’s Guide – Buying an Internet radio

Introduction

You love the sound of overseas radio stations or are fed up with what is playing on the local radio bands, and want to hear something different. You have then dabbled in Internet radio, usually through clicking on “Listen Here” links on radio station sites or using programs and Internet-radio directories like vTuner. You then realise that it would be better to hear this content through a standalone Internet radio rather than moving your laptop computer around and hearing the content through tinny speakers or being tied to your desktop computer.

There used to be a few Internet radios on the market but the number is slowly increasing, with nearly every premium-radio brand or boutique electronics brand running at least one model in at least a tabletop or portable form factor. The units can also pick up podcasts and support “listen-again” functionality for podcasts and similar content. Nearly all of the Internet radios on the market will have a built-in tuner for at least FM and/or DAB digital radio; and, save for a few cheap units, they are capable of playing music held on a computer or network-attached storage device via the home network using at least the UPnP AV (DLNA) protocol.

Where to go

Not many mass-market home-appliance and consumer-electronics chain stores stock Internet radios at the moment because most of these chains perceive that “Average Joe Six-Pack” won’t understand these radios. This is more so in Australia because of it being a smaller market than the UK or USA. You may be lucky to buy a set from the electrical / consumer electronics department of one of the established department stores like Myer, David Jones, Macys, Selfridges or Marks & Spencers; or some supermarket chains like Aldi.

The best bet for finding Internet radios would be to go to an independent audio-video or electronics dealer like SoundStream or Radio Parts Group. Alternatively you could shop online through a place like Amazon or one of the catalogue-driven direct-marketing outlets like Sharper Image, Hammacher Schlemmer or Innovations. There are some manufacturers and distributors like Kogan who supply Internet radios and other equipment through their own direct-sales channels.

What do you need to know

Form factors

Tabletop (mantel) style

Tabletop Internet radios.jpg
Left: Denon S-52 Internet Radio / CD Player   Right: Tivoli Audio NetWorks Internet Radio

Examples: Denon S-52, Sangean WFR-1 Series, Pure Avanti Flow, Revo iBlik RadioStation, Kogan WiFi Digital Radio with iPod Dock

Kogan Internet radio

This is the most common type of Internet radio, where the set is similar to a clock radio or classic mantel / table radio. These units are designed to run only on AC power and have one or two integrated speakers.

 The reason Internet radios have appeared more in this class of set is because there is a renewed interest in this type of radio in the premium radio sector.

Most of these units have a line-level input jack so one can play a portable CD player or MP3 player through the radio’s speakers as well, in some cases, a line-level output to connect the radio to a recording device like a MiniDisc deck; or an external amplifier. Some units will have an integrated CD player, integrated iPod dock and / or USB socket to play music from a USB storage device.

The more expensive units like the Pure Avanti Flow, the Sangean WFR-1 Series or the Denon S-52 illustrated above have a sound quality that is very similar to one of the large high-end “ghetto-blasters” of the early 80s and can be an alternative to a regular bookshelf music system for a small apartment like a studio apartment or a college dorm room.

Portable style

Examples: Pure Evoke Flow, Roberts Stream 202, Revo Pico RadioStation

PureEvokeFlow.jpg

Pure Evoke Flow portable Internet radio

There is an increasing number of portable sets that are the same size as the typical portable radio of the kind with the large handle that sits on many kitchen benches and window sills. Most of these sets have a single speaker and will have a line-level input at least. A few of them can work on integrated batteries, either as a set of D-size cells or a rechargeable battery pack that is charged when the set is plugged in to AC power.

These units will typically have a sound quality reminiscent of the typical large portable radio or 1970s-era mono radio-cassette.

Internet-radio tuner

Examples: Sangean WFT-1 Series, Linn Akurate DS

These units don’t have built-in amplifiers or speakers and are designed to be connected to an existing music system via its line-level inputs or, in some cases, digital inputs. Some of these units may have a built-in DAB or FM tuner and can easily work as a replacement to an existing AM/FM tuner.

Some manufacturers may market these units as network music players because of their ability to play music held anywhere on the home network through the hi-fi system.

Music system or home-theatre receiver

Examples: Pioneer X-Z9 Network SACD Receiver, Denon AVR-5308, Onkyo TX-NR5007

Some tabletop music systems or home-theatre receivers, most notably models at the top-end of most manufacturers’ ranges, have Internet radio and network media playback as an extra “source” or “function”. This is usually to add extra value to these units, especially at this end of the market.

Some manufacturers may also integrate Internet-radio function in to “music-server” or “music jukebox” components. These are components which have an integrated hard disk where music “ripped” from CDs played in an integrated CD player or recorded from line-level inputs is held and can be played through the connected amplifier or, in some cases, provided over the network.

Network Connection

The tabletop and portable units and some Internet-radio tuners will typically have integrated 802.11g WiFi connectivity to a home network’s wireless segment. This connectivity will work properly with wireless networks that use standard WEP, WPA-PSK or WPA2-Personal methods for their security, and usually require the passphrase or WEP key to be entered using a “pick’n’select” method. They also work well if the network has a visible SSID and most of them won’t support WPS or Windows Connect Now “quick-setup” routines or WiFi networks secured to corporate methods. As well, these sets won’t self-connect to hotspots that use common “browser-based” authentication setups.

Some of the tabletop and portable radios and all of the Internet-radio tuners and music systems / home-theatre receivers have a regular Ethernet jack for connection. This connection also works well with HomePlug powerline segments if you connect a HomePlug-Ethernet bridge appropriate to the class of HomePlug segment that you are operating to the Ethernet jack on the set.

Internet station directories

These sets, which are based on one of four platforms (RadioTime, Reciva, Frontier or vTuner), typically work with an integrated directory of Internet streams and podcasts that is able to be updated over the Internet. This can be done automatically or manually with the user pressing an “update” key. They also work with a Web portal which allows you to have a list of “online favourites” alongside the favourite streams associated with the set’s preset buttons.

The Web portals also exist for uploading a user-specified streaming-audio URL to the radio, which can be good for adding new Internet radio streams to your set.

Choosing the right Internet radio for your application

This is similar to choosing a regular radio, especially a premium radio set or music system / component, but you will have to factor in what kind of Internet connectivity you are running. If the site is capable of operating an 802.11g WiFi network or 2.4GHz 802.11n WiFi network operated in “compatibility mode” and secured with WPA-PSK or WPA2-Personal, you can use any set that works with WiFi networks such as all of the tabletops and portables. On the other hand, you may have to prefer a set with an Ethernet connection and, in some cases, use a pair of “homeplugs” to locate the set where you want to have it.

As far as bringing Internet radio to the hi-fi or home-theatre system is concerned, an Internet-radio tuner may be what you need if you are happy with your current  system or have just bought a new receiver or music/AV system. As well, some of the tabletop and portable radios have a line-level output which can be another way of bringing Internet radio to your music system. You would have to make sure your existing equipment has a vacant line-level input such as an AUX, TAPE, CD or TUNER input. On the other hand, it may be worth factoring in Internet radio and network media playback as a feature to look for when upgrading or replacing your receiver or system.

Other things to know

Once you own one of these sets, it may be worth reading the DLNA Media Network series of feature articles in this blog, especially “Getting Started With DLNA Media Sharing” to understand the UPnP AV media player functionality that these sets offer. This can help you “liberate” your music collection held on your computer’s hard disk through your newly-purchased Internet radio,

Some of the Internet radios, most notably the Tivoli Networks and the Pure Evoke Flow are designed along the classic two-piece stereo principles that used to be practiced with some consumer-electronics equipment during the 1950s to 1970s, and commonly practiced with cheaper computer speakers. This is where the radio has one integrated speaker that yields mono sound but, whenever it is connected to a matching accessory speaker, it can yield stereo sound. Most of these sets that work that way have the accessory speaker supplied as an extra-cost option.

Conclusion

Once you know what is involved in purchasing an Internet radio, you can enjoy the fun of overseas, out-of-town and offbeat radio without needing to be near your computer.
