At the recent International Broadcasting Conference (IBC) to become the center of attention, all kinds of mutual Competition Mobile TV (TV-on-mobile) standard advocates, also competing specifications, was quite the industry attention.
Was swept into the struggle of incompatible formats, including: digital radio broadcast based on Eureka147 Standard Of DMB (Digital Multimedia Broadcasting), ground Digital TV Standard mobile version DVB-H (Digital video broadcasting – handheld); and a proprietary format developed by Qualcomm MediaFLO.
DMB and DVB-H proponents both demonstrated they can receive cable broadcast handheld model. Such as IBC, LG Samsung and PresTel massive mobile phone devices. They are available from the Dutch economy Services Department Organization The pilot network to receive live DMB mobile TV signals, and in the city of Amsterdam General . At the same time, Nokia (Nokia) of the handheld device can be located at the RAI from a just Meeting Outside the center’s 100-watt Launch Tap on the pick up broadcast signals. Nozema Services provides DVB-H based mobile TV signals.
Competitive format for DVB-H proponents claim that indoor reception signal can not solve the problem with that, Nokia executives TimoLahnalampi retorted: “We stand here to receive live (live) broadcast signals without the use of any repeaters. ”
But MediaFlo where? Surprisingly, Qualcomm’s system does not demonstrate at the show appeared on the live broadcast.
Industry focus turned to practical issues of spectrum availability
Industry in the IBC on the bone of contention has been from “Who is willing, in his Mobile Watch TV? “To many real-world implementation issues. They include: frequency availability, network Planning , Cell phone antenna design the infrastructure cost and interoperable mobile TV handsets will be available to the network quickly Operation Business and so on.
In addition, an increasingly obvious fact that the mobile TV market will test and early commercial deployment of the process, remain fragmented, even within the same country. This is mainly because of the availability of UHF-band spectrum varies significantly between countries. In addition, while everyone can see the emerging mobile TV market in the bucket of gold at the waving, the taste of political interference gradually thicken.
DMB in South Korea and Japan has taken off, but the DVB-H is wall flowers outside. DVB-H supporters promised an initial 2006 commercial deployment, large-scale launch in 2008.
Manager JuhaniHuttunen Nokia solution that would interoperate DVB-H terminals to the market to bear a “tremendous market pressure.” “Operators are demanding more from their suppliers must specify the source supplier,” he said. To date, Siemens , Motorola Mobile phones and Dell The PDA has been Test , And DVB-H interoperability and compatibility. With the large number of global trials DVB-H, the dilemma now is to “test run of Standards and real-world experience simultaneously,” Huttunen said.
Nokia plans to introduce its own “open air interface” specification, and published in the company’s Web site. Nokia Multimedia Business Unit Vice President RichardSharp that his company will build in a smart phone platform in SymbianOS?? Series 60 platform, integrated DVB-H. He promised the product in 2006 Listing .
