Tweet this on your lounge-room TV with Panasonic

Panasonic Adds A Twitter App To Its Viera Cast Plasma HDTVS

My Comments

First, they did it by enabling video conferencing with Skype, now Panasonic are allowing you to Tweet a comment about that show you are watching or follow your Twitter friends on your lounge-room TV. Who knows not if but when Facebook will become the next add-on for Panasonic’s Viera-Cast TVs and Blu-Ray players. These sets will also need to work with a remote control that has a QWERTY alphanumeric keyboard so you you can get those Tweets or status updates out as that show progresses.

This happens to be highly relevant as an increasing number of television shows, mainly sports, talk shows, current-event broadcasts, reality TV and the like integrate Twitter in to their content and have set up a particular hashtag associated with that show. This typically includes the use of a “Twitter crawl” that appears at the bottom of the screen and / or the show’s compere or anchor citing selected Tweets directed at the show.

It is becoming the direction for manufacturers to extend the common social-Web and Internet-driven-communications platforms to a “10-foot” experience on the lounge-room TV or video peripheral (Blu-Ray player or “personal-TV service”) either by providing the function as an “app” that you choose from an “app-menu” or “app-store”; or as part of a firmware update that is rolled out to the device.

This may require a change in the direction on how the remote control for the TV set is designed. This may be in the form of a handset that mimics the Nokia N97 Mini smartphone where the top of the remote swings away to reveal a QWERTY keypad; a handset that looks like a BlackBerry or Nokia E-Series smartphone or simply an app for the common smartphone platforms which provides TV control as well as a link between the phone’s text-entry keyboard and the TV. It may also mean that the infra-red remote control will go the way of the ultrasonic remote control and be replaced by a Bluetooth or Wi-Fi remote control. Other solutions may also include support for standards-based Bluetooth keyboards like the Logitech diNovo Mini or Microsoft’s Media Center keyboards.

In this case, there will need to be an interest in designing more of the multimedia keyboards that appeal to being operated while you are slouching on the couch. This will mean keyboards that are backlit when they are used, small keyboards that can be worked with two thumbs; keyboards resistant to damage from crisps (US: chips) and sweet drinks that are often consumed in front of the telly and elegant-design keyboards.

Now it will certainly mean that the TV isn’t just for watching your favourite shows any more. It will also be about integrating the social Web with the experience.

Another one for the Android-based TV platform

Sony Internet TV Has An Intel Atom Processor And Runs Google TV, Chrome, Flash 10.1 | Sony Insider

From the horse’s mouth

Sony’s official Internet TV Website – Sony Style

My comments

Previously, I had written in my blog about People Of Lava introducing an Internet-enabled TV that was based on the Google Android Platform. This is a brand that may not be on everyone’s lips, especially when it comes to consumer electronics.

But now Google had determined an Android-based app-driven TV platform to go alongside their Android app-driven mobile phone platform and described it as “Google TV”. They have pitched this at digital TV sets and various set-top applications, primarily as an open platform for delivering Internet-enabled interactive TV.

Sony have become the first mainstream TV manufacturer to implement this platform, which will give it an air of legitimacy in the consumer-electronics space. This is eve though the interactive-TV space has been dominated by various closed or limited platforms like the games consoles, the PVR boxes such as TiVo, and various pay-TV platforms.

I often wonder that if Google keeps the Android platform as an open platform, they could provide many interesting applications and uses for many devices.

Product Review – OXX Digital Classic DAB+ tabletop Internet radio

simonmackay 10/05/2010 IP-based broadcasting, Product Review, UPnP AV / DLNA media-playback hardware) No Comments

I am reviewing another of the Internet radios that are in that “mantel-radio” form factor like the Kogan Internet radio that I previously reviewed. From what I have noticed, it was as though it was the Kogan radio but without an iPod dock and in a glossy white cabinet.

The set is connected to mains power via a mains cord that is attached to the set rather than the usual AC adaptor that plugs in to the set. This is more in line with the traditional mantel radio or most of the clock radios that are currently ins use and will be likely to benefit people who have to deal with crowded power outlets and powerboards,

The set uses a bitmap LCD display which yields a large clock display whenever it is turned off and provides a useable menu display. The knobs are of an equal shape and all the buttons are lined up under the display in a single row. This may impair useability for older people because the labelling is too small.

On the other hand, the volume control is a real analogue volume control rather than the rotary encoder that I have used on most Internet radios and other recent consumer electronics. This will appeal more to mature people who want greater control of the set’s output volume – I have even heard that a sign of a person’s maturity is knowing that the volume control can be turned down rather than always up!!!!

Connectivity

Kogan and OXX Internet radios alongside each other

Like the Kogan table radio, there is an auxiliary input for external audio equipment like MP3 players and Discmans as well as a headphone jack which you can use as an external speaker jack when connected to active speakers.

It also excels on network connectivity through the provision of an Ethernet socket for use with wired networks, including HomePlug powerline networks. The wireless-network connectivity has been improved through support for WPS “push-push” setups as well as network profiles for multiple different wireless networks.

Lately, I had visited another location where this set was in use as a kitchen radio and was setting it up to work with a multiple-access-point wireless network and it shows each access point as a single entity even though the network was set up as an extended-service-set. This is still a problem with the Frontier chipset Internet radios because they are presumed to be kept in a single position rather than moved around the network. As well, the WPS “push-push” setup experience went very smoothly without a problem when I enrolled it with a router that was set up to work as an access point.

Use

There are four preset buttons for each of the operating bands as well as support for integration with the “www.wifiradio-frontier.com” Internet-radio portal. This then allows for a larger list of preferred stations to be kept consistent across multiple sets.

The unit also has improvements in other areas like dead-programme “clean-up” with DAB multiplexes for sets that are moved between towns or whenever the multiplexes are rearranged. Similarly there is also an equaliser function with five tone presets and manual adjustment for bass and treble. There wasn’t a loudness-compensation control on the manual tone adjustment unlike other Frontier radios with similar firmware.

It does work well with DLNA media services, especially the TwonkyMedia Server that is part of the Western Digital MyBook World Edition network hard disk. At the moment, it only works as a media player that can be operated from its control surface.

Bitmap display on OXX radio

When this set is run at a loud volume, it sounds as loud as the Kogan set, which is loud enough to cut over noisy kitchen appliances for example.

Limitations and Points of Improvement

One main limitation that I have experienced is the tendency to work on a small buffer which causes the radio to “start and stop” especially when playing some overseas Internet radio stations. It may be also limited through problems with Wi-Fi networks that may be difficult in some areas. The problem may also become worse as more people “hit on to” Internet radio – the new “short-wave” band, and servers don’t work well for quality of service. Other radios don’t seem to be as sensitive to this problem as much as this model.

A point of improvement that I would like to see would be steps to make the set more ergonomic and easier to use. For example, I would like to make the buttons more prominent so they are easier to find. This is more so for the on-off button and the mode button. As well, the LCD display could be better replaced with one of the monochrome OLED displays to improve on readability, or could be engineered to fill the display panel space more to make better use of that space.

Other than that, there wasn’t any other main limitation with this particular set for its class.

Conclusion

Although there is the limitation with the set working on a small buffer and being more prone to “start-stop” behaviour with Internet radio, it can work well as a tabletop radio / network media player for an office, waiting room, small shop or kitchen. I wouldn’t recommend this set for use in a workshop or similar location because of the glossy finish being more susceptible to damage that occurs in those areas.

Update note – 18 May 2012

I have added some further experience notes about the OXX Digital Classic DAB+ Internet radio since this review was published. This is due to my using a a radio of the same model that had been purchased by someone whose home network I was servicing and optimising.

My comments

I was not surprised with the Google Android software being implemented as an embedded-applications platform beyond the smartphone and Internet tablet. Here, “People Of Lava” have introduced a range of Internet-connected main-lounge-area television sets that use Android as their operating firmware. In fact, what’s more is that these sets are open to the Google Android Marketplace so that users can add extra functionality to them by drawing-down the appropriate apps.

What I also liked about this design was that a lot of the design costs were cut out for the manufacturer because they didn’t need to design an operating environment from the ground up when they wanted to design the equipment. It has also provided an easier path for user customisation, which may be of benefit with Internet-based TV services like IPTV and catch-up TV; and sets deployed in hotels and similar businesses.

This has then proven that the Google Android platform can become a serious contender for the embedded and dedicated-purpose operating system marketplace.

Product Review – Revo IKON stereo table Internet radio (Frontier Internet Radio platform)

simonmackay 30/03/2010 IP-based broadcasting, Product Review, UPnP AV / DLNA media-playback hardware) No Comments

I am reviewing the Revo IKON, which is the first Internet radio that I have reviewed to be designed in a similar manner to a classic boombox. Here, it has been designed with that similar footprint in mind and also is equipped with stereo speakers that are angled outwards.

Description

The unit actually has an oval shape and has a pop-out iPod dock on the front, under a colour LCD touchscreen which is the set’s main user interface. The volume knob and the power button are located on top of the set, although the volume knob is a rotary-encoder type which doesn’t show on the display what volume position you have set it to.

Operation and Sound Quality

The colour LCD touchscreen is easy to read and the user interface that it presents to you when you select stations or other options is similar to an automatic teller machine that uses a touch-screen. The home menu shows a list of all the sources available – DAB, FM, Internet, LAST.FM, Media Player (UPnP AV), iPod dock and auxiliary input.

It also comes with a remote control which offers volume control, snooze / sleep control, transport control for the UPnP media player function or attached iPods, LAST.FM song voting as well as the ability to turn the unit on and off. You don’t have the ability to change stations or sources from this remote control.

If you are using the Internet radio mode, you can’t have ready access to the preset stations like you can with DAB or FM where you press a star icon to see the preset list. Instead, you have to meander around the menus to see the preset list. This can be an annoyance to those who tune in to local RF-based radio and are likely to visit Internet radio programs frequently and can be a pain for older users.

The unit works with DLNA-compliant media servers but you have to use the touchscreen or remote control to navigate the DLNA media server. This is common with Internet radios because Frontier or Reciva, who make most of the firmware for these radios don’t support “three-box” operation using UPnP AV Control Points.

The set supports LAST.FM and can allow users to “scrobble” (expose listening habits to LAST.FM) content from LAST.FM content or from content from a UPnP AV / DLNA media server.

The set has a “clean-up function” that makes it easier to manage changes to the DAB station list, which can be of importance if it is taken between locations or the DAB multiplexes in a city are being re-arranged.

iPod dock exposed

The set has a similar tone control to the previously-reviewed Revo Domino, where you can select one of five tone presets or set up a customised tone preset. Here, you have bass and treble controls and a loudness-compensation switch. Infact, the “normal” tone preset is with flat bass and treble settings and with loudness compensation switched on.

Speaking of the sound, the sound quality is very similar to most of the low-end to mid-range portable radios made through the late 1970s to early 1980s. It can also fill a small to medium-size room with sound in an intelligible manner.

Connectivity

The set can work with WiFi networks that use conventional WPA2-PSK passphrases or can be “bonded” to routers that support WPS “push-button” configuration. This function should be made available not as a WiFi network option but as part of the setup wizard. It can store the parameters relating to four different WiFi networks, which can be useful for home networks with more than one SSID or if you take the radio between multiple locations.

This radio also has an Ethernet socket which adds plenty of flexibility to how it is connected to the Internet. Here, you could connect it to a HomePlug or MoCA “existing-wires” segment using the appropriate bridge adaptor, a WiFi network that it can’t connect to using a WiFi-client bridge or directly to to an Ethernet network like in business premises.

There is only one external output socket in the form of an SPDIF optical socket for connection to a digital amplifier, home-theatre receiver or a digital recorder like a MiniDisc deck. This is limiting as far as outputs are concerned because a set like this could benefit from an analogue output like a headphone jack (to connect to headphones or external active speakers) or a line output jack (to connect to another amplifier or a cassette deck).

Advantages

One main advantage with this set is the stereo sound provided by the two speaker systems built in to the unit. This is an advantage compared to the Internet radios that I have been reviewing in the blog so far. The other main advantage that this set has is the ability to work with an Ethernet network rather than just a WiFi wireless network, which opens up a world of flexibility.

Other features that I like include the colour display, improved DAB handling and support for stations that present logos as part of their Internet-radio streams.

Limitations and Points of Improvement

One main limitation with the Internet radio function is the inability to access the preset-station list from all of the Internet-radio screens unlike what you can do with FM and DAB. This limitation could be rectified through a software update and impairs an otherwise very good Internet radio.

The other limitation with this set is the lack of a headphone jack or line-level output. This also limits the flexibility that the set could offer as far as connection to external audio equipment is concerned.

Conclusion and Placement Notes

Other than the few limitations concerning output connectivity and ready access to Internet-radio presets, this radio does have a lot going for it as a general-purpose Internet table radio.

It would work well as a radio for a kitchen, office or small shop, especially if it is used as a direct replacement for an older boombox or iPod dock or as an upgrade from a single-speaker Internet radio like the Revo Domino or Kogan Internet radio.

BBC reception problem now rectified for Kogan Internet radios

simonmackay 18/03/2010 IP-based broadcasting, UPnP AV / DLNA media-playback hardware) 1 Comment

Kogan Internet table radio - BBC updates now available

Over the last few months, those of you who own a Kogan Internet/DAB+/FM table radio, which I have reviewed in this blog in November, wouldn’t have been able to receive any Internet radio services from the BBC. It may be of concern to UK expats or Anglophiles who have bought this radio primarily to listen to the sound of the BBC radio stations that broadcast there like BBC Radio 4. The symptom was typically in the form of the radio showing “Network Error” when you select a BBC radio service. This was because the BBC were doing a technical re-engineering of their online radio streams and were moving away from the original Real-Audio streams to newer technologies.

vTuner had updated their “master” Internet radio directory which services Frontier-based sets as well as a lot of other Internet-radio designs to reflect the BBC changes. The set manufacturers had to then roll out the updates to each of their set designs through the over-the-air updates. In the case of this Kogan table radio, it took a frustrating long time for the update to materialise because the OEM who makes these sets had to make sure it was working properly before releasing the update.

As of 18/03/2010, Kogan have rolled out the updated directory to these radios and next time you turn on the set and select “Internet radio”, you will have an “update notice” appear on the display. Press the INFO button in response to this “update notice” and wait for the update to complete. The radio must not be disconnected from the power at all during this process. The progress of the update is highlighted with a “fuel gauge” bar that appears on the bottom row of the display and when the set is updated, the display will show “Press SELECT to continue”. At this point, press the large “tuning knob”, and the set will restart and, a while later, the last Internet radio station that you listened to will play.

Then you can tune to the BBC stations using the menu system or recall any BBC stations that you previously allocated to the preset buttons. This update does not affect any other functionality or personal settings that you have established when using this set.

If you had bought one of these radios and the BBC reception problem had made you think of returning the radio to Kogan, now you don’t need to do so because of this update/

Now Google is proposing search for the big screen in the home

Google Testing TV / Web Search on DISH Network Set-top Boxes | eHomeUpgrade

Video business-news bulletin including story about Google’s TV / Web search

My comments on this technology

Google has become a byword for searching for information on the Internet in a similar manner to the way the word “Walkman” became a byword for personal stereo equipment or “Hoover” became one for vacuum cleaning. Their presence is now strong on the computer screen and the mobile screen, but the territory that they haven’t conquered yet is the television screen.

Now they are working with DISH Network (one of two major satellite-TV services in the USA) to develop a TV-show / Web search user interface for use on the set-top boxes that DISH Network provide to their satellite-TV customers. Could this mean that we could be able to find RF-broadcast content as well as content on the Web like YouTube clips or Web sites such as online episode guides. They reckoned that this may need the use of a QWERTY keyboard near the TV.

But I have observed an increasing furtherance towards text entry from the couch, which would be important with Google’s TV/Web search. For example, some remote controls are implementing text entry on a 12-key keypad similar to how those teenagers type out text messages on their mobiles and others, including TiVo are issuing remote controls that have a slide-to-expose QWERTY keyboard for text entry. On the other hand. there have been manufacturers who offered small wireless or USB keyboards being pitched at “lounge-room” use.

This is even though I have seen situations where teenagers have brought laptops in to the lounge area so they can IM or Facebook friends while watching their favourite TV shows, or where I have used Google or the Internet Movie Database from my mobile phone to search for information relating to a show that I am watching.

So it definitely shows that the Internet is becoming part of the regular TV-viewing life rather than a separate activity.

First production car with Internet radio to be presented at Geneva Auto Show

Mini Countryman to be first production car with internet streaming radio? – Engadget

MINI Connected Technology Adds New Infotainment Options, Debuts in Geneva | Motor Trend (USA)

My comments

Previously, I had talked in this blog about the idea of Internet radio in the car and the way this goal would be achieved. Now BMW have integrated Internet radio functionality of the kind that the Kogan Wi-Fi Internet Radio, the Revo iBlik RadioStation and the Pure Evoke Flow provide in to the Mini Countryman as part of the Mini Connected infotainment pack.

The article had described some of the gaps about how this goal would be achieved, but I would reckon that the technology would be based on a user-supplied 3G USB dongle or tethered 3G phone; or an integrated 3G modem working with a user-supplied USIM card. They talked of the idea of choosing a few stations from a directory akin to the vTuner / Frontier Silicon or Reciva Internet-radio directories and allocating them to presets so you can “switch around” your favourite streams. The author had suggested that there may be a reduced station list and that, for example, his favourite “speed-metal” Internet station may not be in the list. But if the software works in a manner similar to Frontier’s “wifiradio-frontier” or Pure’s “Lounge” portals, he could be able to add the “speed-metal” Internet station.

There is a strong likelihood of this feature being available as part of the“connected” infotainment packs supplied by vehicle builders to high-end vehicles at the moment but it could be made available to the aftermarket car-audio scene soon.

Use of broadcast-network tuners to democratise pay-TV

simonmackay 12/02/2010 Current and Future Trends, IP-based broadcasting, Network hardware design, UPnP AV / DLNA No Comments

TiVo, Sony and others to FCC: ‘gateways’ should replace CableCARD — Engadget HD

My comments on this idea

The common situation with most TV households is that if they sign up to a pay-TV service like Foxtel (Australia), a local cable-TV franchise in the USA, DirecTV (USA) or Sky TV (UK), they can only watch TV through the set-top box provided by the service provider. The TV remote control ends up becoming redundant as they have to use the set-top box’s remote control for their TV viewing.

If they want to use a DVR i.e.. a “personal TV service”, they have to use the DVR option provided by the pay-TV provider rather than get a retail DVR solution like TiVo, a home-theatre PC such as Windows Media Center or one offered by a major consumer-electronics brand. In some situations like some cable-TV implementations in the US, you may be able to use a retail DVR solution along with a special “CableCARD” and, perhaps, a “tuning adaptor”. But this doesn’t provide the full service that the customer has put money up for, such as interactive TV or access to “pay-per-view” or “on-demand” content.

As well, a lot of these providers often charge an extra fee if the user wants to deploy a set-top box in other rooms. This typically means that one TV set, usually the one installed in the main lounge room or family room, is subscribed to the pay-TV service. At best, most users may deploy the second set-top box in a secondary lounge area like the rumpus / games room.

What is the layout preferred by TiVo, Sony and others?

The layout would consist of the following:

A “gateway device” or broadcast-network tuner connected to the cable service or satellite dish which “tunes” the pay-TV services and manages access to these services. It then makes them available over the home network using IP-based standards and technologies. This device can also pass back information relating to “pay-per-view” content orders or interactive television from the endpoint devices. It can also handle on-demand content offered by pay-TV providers in the convention context and fulfil the content to the desired end-devices.
Standards-compliant endpoint devices (TV sets, DVRs, etc) that are connected to the home network and discover the services and content using technologies like DLNA. These devices can work with interactive services provided by the TV service provider and provide the viewer’s responses to the gateway device via the home network.

This is similar to the “broadcast-network tuner” setups like Devolo’s dLAN Sat, the Tivit ATSC mobile DTV WiFi tuner and the HD HomeRun tuner, where there is a digital-broadcast tuner that passes the signal via an IP-based home network to a hardware set-top box or software player program in a general-purpose computer so people can view the TV programme. These solutions typically used a non-standard control method and, in most cases, a single RF front-end so that only one TV set could operate at a time and they couldn’t work with a DVR or similar device.

Why develop this layout?

There is a desire for true competition in the multichannel pay-TV industry concerning end-user devices that is similar to what has occurred with telephone hardware since the Carterfone Decision in the USA and the Davidson Inquiry in Australia. One of the goals is to provide a TV navigation interface that encompasses off-air, pay-TV and IP-delivered content in the one electronic programme guide. This guide’s interface would be “skinned” to match the host device’s branding or any user customisations that are available to the device’s user. It also means that the user only needs to deal with one remote control to find whatever they want to watch.

This kind of layout could allow each TV set and each computer in the house to have access to all of the pay-TV services, rather than the common situation of having to deploy pay-TV set-top boxes to each place where there is a TV set.

There is the ability to upgrade the gateway to suit changing technological needs such as change of infrastructure or improvement in transmission or security protocols. That same ability also exists if the user wants to change providers or sign up to a supplementary-content service. Here, in all the situations above, there is no need to replace the end-user’s devices like DVRs or Internet-enabled TV sets, nor is there a need to replace software on any of the computers in the house to accommodate these changes.. In these cases, the software or firmware can discover the new services that are provided through the new hardware.

What needs to happen

One thing that needs to happen is high-profile implementation of common standard technologies like UPnP AV in the broadcast-reception sphere. This includes having endpoint and recording devices work to these standards when discovering and receiving broadcast signals via an IP network. It also includes the recognition of electronic-programme-guide data provided by these gateway devices, especially if the device that benefits from the data is a recording device like a “personal TV service”. It doesn’t matter whether the client device has the programme-guide data or the broadcast-network tuner has that data. This also includes handling situations where the same broadcast service can be received through different paths such as one or more over-the-air channels and / or a cable or satellite service.

In a similar light, broadband routers that work as the network-Internet “edge” could work as a “gateway” for IPTV services by storing channel lineups and service-authority information for these services. This device may also have to support handling of interactive-TV sessions in situations where the endpoint device cannot handle the sessions itself.

As well, interactive-TV setups would need to work with an IP backhaul irrespective of whether the TV signal is delivered via RF (cable, classic-TV-aerial or satellite) means or via an IP feed. This also includes allowing access to downloaded assets associated with interactive content.

Conclusion

As mentioned before, what needs to happen is the use of common standards and device classes to support broadcast-network tuners; standard viewing and recording devices; and the home network in order to democratise the provision of pay-TV services.

Internet radio in the car – why not?

simonmackay 11/02/2010 Current and Future Trends, IP-based broadcasting, Mobile Computing No Comments

A few weeks ago, a young teenager friend of mine had the Kogan internet radio, which I previously reviewed a sample of and had bought, “tuned” to an Iranian pop-music station that was broadcasting via the Internet. This youth, who had just turned 18 and was about to get his driver’s licence, was asking whether Internet radio in the car would be a reality.

Issues that limit this concept

One of the main issues would be for the wireless-broadband standards like 3G and WiMAX to support media-streaming in a reliable manner and at a cost-effective rate. Recently, there were issues with AT&T raising concerning about Apple iPhone users drawing down too much data, especially multimedia and another 3G provider wrote in to their subscriber terms and conditions a prohibition against media streaming.

The main issues were how these networks handle real-time content and whether they can stream this content reliably when the vehicle is travelling at highway speeds or faster. This also includes how to achieve this cost-effectively without limiting users’ ability to enjoy their service.

One way that it could be mitigated would be for mobile carriers and ISPs to look towards providing “sweeter” wireless-broadband deals, such as integrating voice and data in to single plans. Similarly,the providers could optimise their services to cater fir this kind of use.

Ways of bringing Internet radio to the speakers

Internet radio functionality integrated in car audio equipment

In this setup, the car-audio equipment, whether as part of the in-dash “head unit” or as an accessory tuner box, has access to a TCP/IP LAN and Internet through a modem or an outboard router. It uses any of the common Internet-radio directories like vTuner or Reciva to allow the user to select any of the audio streams that they want to listen to.

Wireless broadband modem integrated in or connected to car audio equipment

The car-audio equipment would have a wireless-broadband modem integrated in the unit or connected to it. The latter situation could be in the form of a USB “dongle” plugged in to the unit, or a mobile phone that supports wireless broadband being “tethered” by USB or Bluetooth to the unit. If the setup involves an integrated modem or an attached USB “dongle”, the setup may use authentication, authorisation and accounting data from a SIM installed in the unit or “dongle”; or simply use the data from a phone that uses Bluetooth SIM Access Profile.

This practice had been implemented in a Blaupunkt car stereo which was being used as a “proof-of-concept” for Internet radio in the car.

Use of an external wireless-broadband router

This method involves the use of a mobile wireless-broadband router which has an Ethernet connection and / or USB upstream connection with a standard “network-adaptor” device class along with a WiFi connection. Of course, the device would have a wireless-broadband connection on the WAN side, either integrated in to it or in the form of a user-supplied USB modem dongle or USB-tethered mobile phone. A typical example of this device would be the “Autonet” WiFi Internet-access systems being pitched for high-end North-American Chrysler-built vehicles or the “Ford Sync” integrated automotive network available on high-end North-American Ford-built vehicles that gains Internet access with a user-supplied USB wireless-broadband dongle.

Here, the car-audio equipment would have a network connection of some sort, usually an Ethernet connection or a USB connection that supports a common “network interface” device class and would be able to “pick up” Internet radio as mentioned before.

Internet radio functionality integrated in an Internet-access terminal

At the moment, this will become the way to bring Internet radio to most car setups in circulations for some time. The setup would typically represent a mobile phone or laptop computer with an integrated or connected wireless-broadband modem. This would have software or Internet access to the Internet-radio directories and stream the audio through Bluetooth A2DP, an FM transmitter or hardwired through a line-level audio connection, a cassette adaptor or an FM modulator.

Increasingly, there is interest from car-audio firms and Internet-media software firms to establish an application-programming interface between a computer or smartphone running selected Internet-radio directory software and the car sound system. This would typically require use of Bluetooth or USB and use a control method of navigating the directory, in a similar manner to how most current-issue car-audio equipment can control an attached Apple iPod.

The primary platform where this activity may take place would be the Apple iPhone, because of it being the most popular programmable smartphone platform amongst the young men whom the car-sound market targets.The setup was demonstrated at the Consumer Electronics Show 2010 in the form of Pioneer and Alpine premium head units controlling a front-end app for the Pandora “custom Internet radio” service installed in an iPhone connected to the head unit via the special connection cable that comes with that unit.

On the other hand, if a smartphone or MID that is linked to the head unit via Bluetooth A2DP does support the AVRCP profile properly, an Internet-radio application installed on that smartphone could achieve the same goal. This would require that the directory applications are able to expose links to the AVRCP commands and requests.There will also have to be requirements to allow “source selection” between multimedia applications through the AVRCP protocol.

Further comments

This concept will become part of the “connected vehicle” idea which provides real-time access to navigation, telematics, communication and entertainment in a moving vehicle or craft, especially as companies involved in this segment intend to differentiate their offerings. It may also be very desireable as an alternative to regular radio in those areas where most regular radio broadcasts leave a lot to be desired.

Once the cost and quality of wireless broadband Internet is brought down to a level that is par with reasonably-priced wired broadband service, then the concept of Internet radio in the car will become reality.
