NEWS ZetaCast advises Ofcom on HDTV |
 |
||
|
ZetaCast is pleased to have been able to assist the UK regulator, Ofcom, by providing an independent review of the potential for restructuring the digital terrestial platform to give more efficient use of the limited multiplex capacity. The ZetaCast Report described a number of efficiency improvements that could be taken in a backwards-compatible manner, including a consistent use of 64QAM modulation and the more effective use of statistical multiplexing. Taken together, these would allow the re-organisation of the current set of SDTV services onto only five multiplexes, without jeopordising reception by existing set-top boxes or integrated digital TVs. The sixth multiplex could then be freed up for use for new services using the latest technologies, allowing it to carry HDTV services through a combination of DVB-T2 modulation and H.264/AVC video coding. |
