Category: IP-based broadcasting

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 Chrysler vehicles or the “MyFord” integrated automotive network 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.

I have written some other posts about the Consumer Electronics Show 2010, mainly about the rise of Android and about Skype being integrated in to regular TV sets. But this is the main post about what has been going on at this show.

TV technologies

The main technologies that were present at this year’s Consumer Electronics Show were those technologies related to the TV set.

US consumers are in a TV upgrade cycle due to the country undergoing a digital TV switchover and are preferring flatscreen sets over CRT sets. This is even though there are digital-TV set-top boxes being made available at very cheap prices and through government subsidy programs. The main reality is that the older sets will be “pushed down” to applications like the spare bedroom with the newer sets being used in the primary viewing areas.

Screen Technologies

The main technology that is capturing the CES show floor is 3D TV. This has been brought on by the success of “Avatar” and requires a 3D-capable TV and, for Blu-Ray discs, a 3D-capable Blu-Ray player. In the case of broadcast content, some HD-capable set-top boxes and PVRs that are in the field can be upgraded to 3D functionality through an “in-the-field” firmware update.

In most cases, viewers will need to wear special glasses to view the images with full effect and most implementations will be base on the “RealD” platform. Some eyewear manufacturers are even jumping in on the act to provide “ready-to-wear” and prescription glasses for this purpose.

Vizio had also introduced a 21:9 widescreen TV even though activity on this aspect ratio had become very dormant.

Blu-Ray

The US market has cracked key price marks for standalone lounge-room players and there is an increase in the supply of second-tier models, especially integrated “home-theatre-in-box” systems and low-cost players.

US ATSC Mobile DTV standard

You may not be able to get away from the “boob tube” at all in America with portable-TV products based on the new ATSC Mobile digital TV standard which has been released to the market this year.

LG are launching a mobile phone and a portable DVD player with mobile DTV reception capability. They are also releasing a mobile ATSC DTV tuner chip that is optimised for use in in-car tuners, laptops and similar designs. Vizio are also releasing a range of handheld LED-backlit LCD TVs for this standard.

A key issue that may need to be worked out with this standard is whether an ATSC Mobile DTV device can pick up regular over-the-air ATSC content. This is more so if companies use this technology as the TV-reception technology for small-screen transportable TVs typically sold at the low-end of the TV-receiver market. It is also of concern with computer implementations where a computer may be used as a “one-stop entertainment shop” with TV-reception abilities.

There is a small Mobile-DTV – WiFi network tuner, known as the Tivit, that was shown at the CES. It is a battery-operated device that is the size of an iPhone and uses the WiFi technology to pass mobile TV content to a laptop, PDA or smartphone that is running the appropriate client software. It has a continuous “battery-only” run-time of 3 hours but can be charged from a supplied AC adaptor or USB port. I consider this product as being a highly-disruptive device that could be deployed in, for example, a classroom to “pass around” TV content, but it also has its purpose as something to show the ballgame on a laptop during the tailgate picnic. The main question I have about this is whether it can be a DLNA broadcast server so that people can use them with any software or hardware DLNA-based media playback client.

Network-enabled TV viewing

This now leads me to report on what is happening with integrating the TV with the home network.

More of the “over-the-top” IPTV and video-on-demand solutions (Netflix, CinemaNow, Hulu, etc) are becoming part of most network-enabled home video equipment. In the US, this may make the concept of “pulling out the cable-TV cable” (detaching from multichannel pay-TV services) real without the users forfeiting the good content. They could easily run with off-the-air network TV or basic cable TV and download good movies and television serials through services like Netfilx or Hulu.

The main enabler of this would be the “Smart TVs” which connect to the home network and the Internet, thus providing on-screen data widgets, YouTube integration, DLNA content access, as well as the “over-the-top” services. Even so, the TV doesn’t necessarily have to have this functionality in it due to peripheral devices like home-theatre receivers (Sherwood RD-7505N) and multimedia hard disks (Iomega ScreenPlay Director HD) having these functions. Of course, games consoles wouldn’t be considered complete nowadays unless they have the functionality.

RF-based two-way remote control

Some home-AV manufacturers are moving away from the regular one-way infrared remote control, mainly in order to achieve increased capability and increased reliability. These setups are typically in the form of a hardware remote control or software remote control application that runs on a smartphone and they use Bluetooth as a way of communicating with the device.

These setups will typically require the customer to “pair” the remote control or the smartphone as part of device setup, which will be an experience similar to pairing a Bluetooth headset with a mobile phone. They have infra-red as a user-enabled fallback method for use with universal remote controls, but this could at least foil the likes of disruptive devices like “TV Turn-Off”.

The main driver behind this form of two-way remote control is to provide a secondary screen for interactive video such as BD-Live Blu-Ray discs. Infact, Michael Jackson’s “This Is It” Blu-Ray disc implements this technology in the form of an iPhone app which links with certain Blu-Ray players to use the iPhone’s user interface as a jukebox for the title.

Smartphones and MIDs

Previously, I had done a blog article on the rise of the Android platform as a challenger to the Apple iPhone market share as far as smartphones are concerned.. There is even talk of Android working beyond the smartphone and the MID towards other device types like set-top boxes and the like, with some prototype devices being run on this operating system.

There is an up-and-coming MID in the form of the Adam Internet Tablet MID. This Android-based unit which can link to WiFi netwoks and has a 32Gb SSD, also has a new display-type combination in the form of an anti-glare LCD / e-ink display

This year. the “smartbook” is gaining prominence as a new general-purpose computing form factor. It is a computer that looks like a netbook but is smaller than one of them. It is powered by an ARM-processor abd could run integrated 3G or cellular calls; and its functionality is more equivalent to that of a smartphone.

There have been some E-book readers shown but these are mostly tied to a particular publisher or retail chain.

Connected Car Media

Pioneer and Alpine have equipped their top-of-the-line multimedia head units with “connected radio” functionality. This function works with a USB-tethered iPhone running the Pandora Internet Radio app. Both these solutions act as a “controller” for the Pandora app, with the iPhone pulling in the online content through that service. The Pioneer solution also offers a “virtual-DJ” function in the form of an extended-functionality app that works alongside iTunes. All these solutions are intended to appeal to the young fashion-conscious male who sees the iPhone as a status symbol and likes to have his car “thumping” with the latest tunes. These solutions don’t seem to go anywhere beyond that market, whether with other mobile-phone platforms or other online-media applications like Internet-radio streams.

Ford  have developed the MyFord sophisticated dashboard and online telematics system and were demonstrating it at this show. This will work with a user-supplied 3G modem and also supports WiFi router functionality. Typically, this will be rolled out to the top-end of Ford’s US market, such as the Lincoln and Mercury vehicles.

Digital Photography

The new cameras of this year have seen improved user-interfaces, including the use of touchscreen technology and some manufacturers are toying with the use of fuel-cell technology as a power-supply method.

As far as network integration goes, Canon have enabled their EOS 7D digital SLR with this functionality once equipped with the optional Canon WiFi adaptor. This solution even provides for DLNA media-playback functionality.

The aftermarket Eye-Fi WiFi SD memory card was shown as a version, known as the Pro Series, that can associate with 802.11n networks.

The unanswered question with network-enabled digital photography hardware is how and whether these solutions will suit the needs of many professional photographers.  The main questions include whether the units will associate with many different wireless networks that the photographer visits without them having to re-enter the network’s security parameters. Another question is whether these solutions can work with higher-security WPA2-Enterprise networks, which is of importance with photographers working in most business, government and education setups.

Computer equipment

“New Computing Experience” alive and well in the US market. Market interested in powerful lightweight laptops that are slightly larger than netbooks. These will be driven by processors that are energy-efficient but are powerful. They could become an all-round portable computer that could appeal to college students and the like or simply as a desktop replacement. The machines that I think of most with this market are the Apple Macbook Pro comoputers that are in circulation, the HP Envy series or the smaller VAIO computers.

Nearly all of these computers that are being launched at the show are running Windows 7, which shows that the operating system will gain more traction through the next system-upgrade cycle.

USB 3.0

There has been some more activity on the USB 3.0 SuperSpeed front.

Western Digital had released an external hard disk that works on this standard, which is known as the MyBook 3.0. This my typically be slow as far as peripherals go because of not much integration in to the computer scene. VIA have also shown a USB 3.0 4-port hub as a short-form circuit, but this could lead to USB 3.0 hubs appearing on the market this year.

ASUS and Gigabyte have released motherboards that have USB 3.0 controllers and sockets on board. These may appeal to system builders and independent computer resellers who may want to differentiate their desktop hardware, as well as to “gaming-rig” builders who see USB 3.0 as bragging rights at the next LAN party. None of the laptop OEMs have supplied computers with USB 3.0 yet.

As far as the general-purpose operating systems (Windows, MacOS X, Linux) go, none of them have native USB 3.0 integrated at the moment but this may happen in the next service lifecycle of the major operating systems.

Some more benefits have been revealed including high-speed simultaneous data transfer (which could benefit external hard disks and network adaptors) and increased power efficiency, especially for portable applications.

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.

Previously, if you wanted extra broadcast content for your television experience, you would have to subscribe to a cable or satellite pay-TV service which would provide many channels of content for a monthly fee. This hasn’t pleased many people because, if they wanted particular sports fixtures or good-quality TV content, they had to subscribe to packages filled with a lot of channels they didn’t really want.

Additional content was available through collectable videocassettes or DVDs; or lately through content-provider Websites which you had to view through a computer.

Increasingly, the broadband Internet service with its content-streaming and file-sharing abilities has opened up a new path for independent broadcast or on-demand video content and led towards “over-the-top” video services.

What is an “over-the-top” video service?

An “over-the-top” video service is an IP-based video service provided in a manner primarily independently of established broadcast TV infrastructure. The customer doesn’t have to sign up with a cable or satellite pay-TV service to benefit from the content. The reception arrangement is typically a set-top box, PVR or IP-enabled TV that is connected to the Internet via the home network. In most cases, especially PVRs and IP-enabled TVs, they will have a built-in digital broadcast tuner that is pitched at receiving free-to-air TV channels or, at the most, the equivalent of basic-tier cable TV.

These services had started out with Web-based services like Netflix, Hulu, Blockbuster Video and similar “video-on-demand” platforms being made available to network media adaptors and “personal-TV-service” devices like Tivo. These services typically provided either pay-per-view or “download-to-own” content, usually encompassing cinema feature movies or television serials. Lately, there has been the arrival of Sky Angel who have set up an IP-based streamed-channel collection based around Christian-focused family-friendly entertainment.

What paths could this open up

These services could open up the concept of “boutique television” which is about a supplementary-TV service providing “only what you want” without paying for “what you don’t want”. In the context of broadcast content, the viewer groups that would be touched would include families who want “clean wholesome entertainment”, ethnic groups who want content in their own language and culture, people interested in sports that aren’t covered in the country they reside in like AFL football or cricket, and those of us who like good-quality television content. As far as on-demand content goes, these programs could open an alternative to hiring DVD from the local Video-Ezy, provide a highly-strung catch-up TV service for people who follow TV serials, amongst other things.

Similarly it could allow content providers like established free-to-air TV networks to offer subscription-TV services and content without being limited by the dominant owners of cable and satellite-TV infrastructure. This was more so when, in Australia, Foxtel (the dominant pay-TV provider in Australia) made it very difficult for the Seven Network to establish a subscription-driven premium TV channel. This had led to a long drawn-out legal dispute and even broke down relations between both services with such behaviour as Foxtel not rebroadcasting the Seven Network to subscriber households that receive their service directly off the satellites; and Seven not providing programme data for Foxtel’s on-screen electronic programme guide.

What needs to be done

Most implementations require the use of a set-top box loaded with specific software, including a content directory in the case of broadcast services. There is the likelihood of a worsening problem if a household likes many different “over-the-top” video services, especially boutique-TV services, where there will be multiple set-top boxes in the AV rack.

One way to go about this would be to establish a standard for provisioning of broadcast and on-demand IP-TV services to subscribers. This could be based around DLNA standards and require at the most a common browser plugin or lightweight application to handle provisioning-manifest files that may be sent by email or downloaded from the service’s Website. As well, the industry needs to act upon content protection / conditional access standards like DTCP-IP when protecting premium services; and accept the idea of covering all receiving devices in a household under one subscription. This is in a similar way to how the TV licence is handled in the UK where ONE TV licence covers all TV-receiving devices in the same household.

How could this affect the TV landscape

For production studios, content providers and “boutique” channels, the “over-the-top” video services will provide these groups, especially small operations, with more opportunities to expose their content. This is in contrast to content being judged on whether it will suit the mainstream audience of a particular market, which is becoming more so in a highly-consolidated highly-controlled market like the USA.

For consumers, it will provide an increased choice of television that gives value for money as in “pay only for what you want to watch without paying for what you don’t want to watch”. This is more so in difficult financial times where one needs to factor in such events as the possible loss of their job or business and need to save as much as possible.

There is an increased likelihood of the commercial TV establishment being threatened by the concept of viewers taking back control of their viewing and the content produced “outside of the establishment” becoming available to most people. They, especially the cable-TV companies and similar companies who run pay-TV services on the same bandwidth, may try to block data streams associated with this new form of video content or implement traffic-shaping rules to Internet service. This would have these companies fall foul of “net-neutrality” rules that are established by governments. On the other hand, these services could force the TV establishment to “lift their game” with content production.

Conclusion

Once “over-the-top” video content comes to your home network and your TV set, it could become a watershed moment for TV broadcasting.
