Mobile TV and video
Mobile TV and video are highly attractive services for mobile devices. However, for many years there have been debates about the best way to deliver these bandwidth-hungry services, for example by streaming them over mobile networks, transmitting them over dedicated broadcasting networks (or modified cellular networks), or sideloading them directly onto mobile devices for subsequent playback. This page contains some of our free analysis of mobile TV and video services, comparing the benefits of different approaches.

Mobile TV: rise of the BBC’s iPlayer on 3G networks
The BBC’s iPlayer has driven substantial traffic growth in fixed Internet networks in the UK. However, its impact has been artificially constrained on mobile networks by the restriction that iPlayer could only be viewed on mobile devices via a WiFi connection. This week, an update to the BBC’s iPlayer application on Apple iPhones and iPads finally allows iPlayer content to stream across 3G networks.
In the last few years, there has been a great deal of hype about mobile TV. At the peak of this hype, mobile TV was being seen by many in the wireless industry as the killer application for mobile phones. Sadly, many within the industry had the wrong idea – believing that mobile users would simply demand live versions of terrestrial TV channels, and a great deal of attention was directed to mobile TV broadcasting technologies, such as DVB-H, which offered the potential of transmitting a relatively large number of live TV channels to mobile devices.
Very few people seemed to realise that the whole nature of TV viewing was changing, and that the needs of mobile users were very different from people relaxing in front of their living-room TVs at home. The adoption of personal video recorders (on satellite, cable and terrestrial TV platforms) has empowered many TV viewers, by separating TV consumption from the TV schedules. At last, people can watch their favourite programmes whenever they want to, rather than having to watch them at the time they are transmitted.
Alongside the adoption of PVRs, we have also seen the rapid adoption of online TV services such as the BBC’s iPlayer. The BBC iPlayer went live (in its non-beta form) in December 2007 – four years ago. For the first time, people could view (and listen to) any programme from the complete range of the BBC’s TV and radio programmes that had been transmitted in the previous seven days.
iPlayer quickly had a substantial impact on fixed Internet networks and ISPs. By June 2008 (only six months after launch), iPlayer accounted for about 5% of all UK Internet traffic, and achieved about five million page views per day. Many ISPs complained that iPlayer was placing too much strain on their networks and that the BBC should contribute to the cost of providing increased capacity. By the end of its first year, 180 million programmes had been viewed.
By September 2011, the number of monthly requests for TV and radio programmes reached 153 million, with an average of 1.7 million iPlayer users per day. On average, each user of TV on iPlayer now streams over an hour of TV content per week. Each user of radio streams over two hours of radio content per week.
iPlayer has now seen considerable expansion beyond PC-based delivery, and versions of iPlayer have been made available on a raft of different devices and platforms, including:
- Virgin Media’s cable video-on-demand service
- Freesat digital satellite set-top boxes
- Freeview digital terrestrial set-top boxes
- Wii, Playstation 3 and Xbox 360 games consoles
- the Apple iPhone and iPad
- Android mobile devices
- a range of other mobile devices, from Nokia, BlackBerry, Samsung and Sony Ericsson.
Despite the availability of iPlayer on a number of mobile devices, its use has been artificially constrained by only allowing content to be streamed via a WiFi connection. So, mobile users have not been able to access iPlayer content via 3G networks. We have long reported that mobile TV and radio services are extremely network intensive, and represent the most challenging services to support for mobile network operators.
While the avoidance of iPlayer traffic on 3G networks has provided respite for mobile network operators concerned about the limited capacities of their networks, such service restriction has also limited the perceived value of mobile Internet services. Increasingly, users expect the services they use on fixed Internet platforms to be freely available on mobile platforms, so it was only a matter of time before iPlayer arrived on 3G networks.
Now that UK mobile network operators have substantially reduced data allowances, they may feel that higher pricing and low data limits are sufficient safeguards to prevent high usage, allowing them to support a less constrained service mix.
In the absence of LTE networks in the UK until 2013 or 2014 (due to much-reported delays to spectrum auctions), it remains to be seen if 3G operators can strike the right balance between controlling network usage and providing a compelling mobile Internet proposition to users. I suspect that many users will be surprised by the speed at which their monthly usage allocation is gobbled up by iPlayer. Furthermore, many may be disappointed by the quality and reliability of the iPlayer service via today’s 3G networks. Extensive deployment of LTE cannot come quickly enough, although Ofcom does not anticipate wide availability of LTE coverage until 2015.
I believe that the launch of iPlayer on 3G networks will profoundly shape the future of mobile networks in the UK, even more than iPlayer has shaped the future of fixed Internet networks. More than any other service, end user expectations for iPlayer usage, performance and reliability will truly set the bar by which users judge their operators. For mobile network operators and mobile users, there’s no going back!

Wireless blog: There are a number of 3G offloading techniques
Not all services and content consumed via 3G devices have to be delivered by 3G macrocell networks. There are a number of complementary delivery methods for the delivery of some, or all, services and content, particularly for users with access to a fixed broadband service.
Dedicated mobile broadcasting technologies, such as DVB-H, DMB and MediaFLO, could deliver multimedia content (notably mobile TV and radio) to 3G devices equipped with appropriate broadcasting receivers. The 3G standard itself also includes a number of mechanisms for broadcasting multimedia content, for example, Multimedia Broadcast Multicast Service (MBMS), evolved MBMS (eMBMS) and Integrated Mobile Broadcast (IMB). Mobile broadcasting avoids the capacity limitations of point-to-point 3G streaming by transmitting the same mobile TV and radio data to all service users. Hence, mobile broadcasting could support very high levels of service penetration and usage without the need to fill 3G networks with multimedia traffic.
Mobile users with access to fixed broadband services have additional methods for the delivery of services. These are:
- indoor systems (WLAN access points or 3G femtocells)
- sideloading.
WLAN is already experiencing strong consumer adoption and this is likely to continue. 3G operators are planning to deploy (or are in the process of deploying) femtocells. Indoor wireless systems potentially allow the broadest range of services to be delivered to 3G devices within range of a 3G femtocell or a WLAN access point (if the mobile handset is WLAN enabled). By doing so, indoor wireless systems could potentially relieve 3G macrocells of a significant proportion of service traffic and use domestic fixed broadband connections as backhaul.
Sideloading is the process of transferring multimedia content (for example, downloaded from the Internet or ripped from a DVD) from a PC to a mobile device (via cable or short-range wireless) for storage and subsequent consumption. The number of mobile devices on the market that feature substantial onboard storage and high-quality displays capable of showing video has increased significantly. Currently, multimedia content (for example, TV and music) is most commonly sideloaded onto mobile devices using a cable but, in future, delivery could be achieved in a variety of ways, including wirelessly via a 3G femtocell or WLAN access point. The complementary methods for delivering services and content to 3G devices have quite different characteristics, as shown in the table, below:

Evaluation of alternatives to 3G macrocells for delivering services and content to 3G devices
TV and video will become increasingly important in the service mix on 3G devices. The ability of each delivery method to support different types of TV and video content is shown in the table below. Of these, indoor wireless systems and sideloading could strongly complement 3G macrocell delivery, by providing high quality of services in the indoor environment.

Press release: Many mobile TV broadcasting options will not be financially viable
Despite high expectations for mobile TV and radio services, only a small number of broadcasting technology options will be financially viable, according to the report, Evaluating the Options for Mobile TV and Radio Broadcasting in Western Europe, written by Unwired Insight.
As consumer demand for mobile TV and radio increases and broadcasting services begin to emerge during 2006, there will be strong competitive pressures on mobile operators to respond. However, according to report co-author, Dr Alastair Brydon, “There is a strong chance that mobile users will not spend a substantial amount on mobile TV and radio services, or video-on-demand and other mobile broadcasting services.”
Mobile operators in Western Europe are already evaluating several broadcasting technologies, including DAB-IP (Digital Audio Broadcasting – Internet Protocol), T-DMB (Terrestrial Digital Multimedia Broadcasting), DVB-H (Digital Video Broadcasting – Handheld) and TDtv, alongside the option of relying on enhanced 3G networks. If they opt for a dedicated broadcasting technology, they must decide whether to build their own networks or to share the cost and risk with other operators and/or broadcasters.
Financial modelling presented in the report reveals that small operators will have a very limited choice of viable options. According to Alastair Brydon, “Sharing a broadcasting network with a number of other mobile operators will be essential. With a shared network, either DAB-IP or DVB-H could yield attractive returns,” says Alastair Brydon. While DAB-IP is potentially the cheapest solution, it is only appropriate in those few markets where DAB has been deployed extensively. Furthermore, only a limited range of DAB handsets and broadcast channels may be available. DVB-H is currently attracting the most interest from mobile operators in Western Europe and is the most likely to achieve significant economies of scale on both infrastructure and handsets.
Mobile operators with a large customer base have more options than smaller operators. “While a shared DAB-IP or DVB-H network could provide a strong financial return for a large operator, some may want their own broadcasting networks, to differentiate themselves from competitors,” says Dr Mark Heath, report co-author.
Mobile operators wanting to own broadcasting networks have two viable options: building DVB-H networks or upgrading their 3G networks to TDtv. “TDtv would allow mobile operators to reuse existing cellular base stations and operate in already-licensed TDD (Time Division Duplex) spectrum, making it considerably cheaper,” says Mark Heath. “While DVB-H is also viable, operators must try to avoid high spectrum costs and the use of the more expensive L-band spectrum, which would require significantly higher take-up and revenue per service user to achieve a good return.”
Evaluating the Options for Mobile TV and Radio Broadcasting in Western Europe, evaluates the realistic deployment options for each of the mobile broadcasting technologies that are likely to be used in Western Europe. The report identifies the options most likely to be commercially viable for different operator types and circumstances, and quantifies the take-up and revenue per service user needed to achieve an adequate financial return from each.
