Nokia Mobile TV Content
November 9, 2008 | Electronics, Mobile TV, Nokia | 3 CommentsA competitor in the mobile television standard DVB-H is DMB (Digital Media Broadcast). This standard was recently introduced in South Korea where it is already used by over 400,000 users at home (based on satellite) and 40,000 by users on mobile devices of terrestrial broadcasting. DMB is an improvement of the Eureka-147 DAB (Digital Audio Broadcast) standard, already widely deployed (coverage in Germany is about 80%). However, it has not yet been sufficiently accepted by users. DMB, DAB uses a channel with a bandwidth of approximately 1.5 MHz. This allows simultaneous transmission of 3 to 4 television with a time of zapping around 0.5 seconds between channels.
mobile TV via declining or streaming TV channels on mobile networks as UMTS, WiFi, WiMAX, is an alternative approach. It is particularly suited for personalized services, like video on demand and pay-per-view services, or interactive, mobile network-related services where audiovisual media are used (for example, advertising, lease / Web-based services, virtual tourism guide). However, the simultaneous transmission of content through television live video streams can quickly become problematic because of network congestion if too many users are down continuously on the same channel.
Controversial discussions are still ongoing, whose content and services that May is best suited for mobile TV. Watching a movie on a small screen of a handheld seems less likely that the supply flow or short television TV-loops, such as news, sports, music videos, or trailers. It could also be interesting to combine mobile TV content (for example, indices or labeled to facilitate the search) with mobile phones for back-channel interactive value added services. In addition, the inclusion of IP services offer an entirely new portfolio with new media services.
Mobile TV, without doubt, is a hot topic today. After a number of field tests in the past, the 2006 World Cup should be an ideal platform to demonstrate this new medium, and it could become the breakthrough of new technology. However, many experts are skeptical that this event in May are still a little early because no exciting services can still be demonstrated. In addition, different, incompatible systems May confuse potential users. Many problems – frequency of services, different technologies – are not yet finally resolved, it is not yet clear whether and how mobile TV could become a business, the extent to which users accept this new media, and how they could be charged for mobile TV services.
