Alcatel announced today the successful demonstration of Europe’s first broadcast of live TV channels on mobile handsets in S-band. The demonstration took place in Alcatel’s UK premises. It is using the new DVB-SH standard (Satellite services for Handhelds), which is currently being drafted by the DVB Project. To perform this demonstration, Alcatel was assisted by UK broadcasters Sky, ITV and BBC.Representatives from European mobile operators, TV broadcasters, industry analyst firms and regulatory bodies attending this demonstration were able to enjoy high quality images displayed on SAGEM myMobileTV handsets. These terminals are using the S-band telecom frequency between 2.17GHz and 2.20GHz, which is adjacent to the 3G/UMTS band. 30MHz of spectrum is currently available all across Europe and in other major regions in the world.
DVB-SH is a new technology targeting the S-band. DVB-SH is a related standard to DVB-H. With DVB-SH technology, Mobile TV signals can be broadcast from satellites as well as from terrestrial transmitters directly to handhelds. DVB-SH handhelds can be designed in such a way that they become compatible with DVB-H so that both standards can be received in one end-user terminal.
In addition, Alcatel demonstrated two possible key technical features using the DVB-SH standard. Reception Antenna Diversity, a feature using two antennas inside the same mobile device, enables improvements in the signal quality under difficult conditions. Furthermore, improved Time Interleaving overcomes fading impairment in mobility conditions. The significant quality enhancement was demonstrated by implementing these DVB-SH features.
On the occasion of this demonstration, Professor Ulrich Reimers, Chairman of the Technical Module of DVB Project declared: “I am delighted to have been given the opportunity to witness a live Mobile TV demonstration in the S-band even before the new Mobile TV standard has been finally designed. Within the DVB -Project, we have decided to give that standard a new name - DVB-SH - digital video broadcast from satellite for handhelds. DVB-SH is a perfect complement to other standards, such as DVB-H, which is typically using UHF frequencies but is capable of using the L-band. Thus DVB-SH may have a significant impact on the global Mobile TV industry.”
