    Does anyone know what codec is planned for European HD broadcasts. When bandwidth is in short supply wouldn't it make sense to use H.264? For some reason the US use 20Mb/s MPEG-2 but does this mean we will follow?

    Euro 1080 are currently broadcasting their HD-1 channel in MPEG2. However they plan to simulcast in MPEG4 H264 AVC ASAP.

    BSkyB and Canal + are both going to be using MPEG4 H264 AVC in Europe. They are also both likely to use DVB-S2 modulation - to get more data through a given satellite transponder.

    MPEG2 looks unlikely to be a widespread compression system for HD in Europe.

    I believe Euro1080 are only going to be simulcasting in MPEG-2 until 2008. So much for that viewing card lasting 5 years...

    I understood the move to MPEG4 was global and made possible by the recent development of chipsets, which support both MPEG2 and MPEG4.

    The Euro1080 MPEG4 service is scheduled to start in June 2005. The MPEG2 service is to continue until Jan 2008 but the smart cards are valid until 2010 and work for both MPEG2 and MPEG4.

    In the US some subscription satellite providers are moving their MPEG2 HD services to MPEG4 over the next year or so, with existing receivers being swapped out for MPEG4 versions I believe.

    However the OTA "free-to-air" terrestrial system will remain MPEG2 AIUI - as otherwise there would be a need to swap out OTA receivers (and TVs with OTA receivers built in)

    Whilst it is true that MPEG4-capable receivers are also likely to be backwards compatible with MPEG2 broadcasts, this doesn't mean that existing MPEG2 receivers would be compatible with MPEG4 broadcasts - quite the opposite.

    Absolutely, Euro1080 hope to have the new Mpeg4 receivers available by June though.

    Does that mean they would swap out an MPEG2 receiver for a nice new MPEG4/2 receiver? I doubt it...

    Hi Steve, I don't think they supplied any MPEG2 receivers but from their recent press release it looks like they might be supplying MPEG4 receivers in the future. In any case they have guaranteed MPEG2 transmission until 2008 which would bring you to a second or third generation MPEG4 receiver. As far as I know there are no advantages to the end user with MPEG4 unless you are recording in which case disk space would be an issue and I don't know of any 50Hz HD STB's with recording capability.
