iv not seen anything much on DVB-C2, DVB-T2 or DVB-H2 for that matter, does anything exist yet for them?.
not that its ever likely that NTL will ever let you rent or buy a DVB-C(2) card to put your payed for smart card into and just take the .ts content directly to your monitor or HD ready display and hence get a far better quality picture without the anologue conversion that the SD STB does today.

VC1 or Windows Media 9 codecs offer similar performance to H.264 or MPEG4 Part10 codecs.
Curently for the UK market, only the BBC and Sky are doing transmissions over satellite with MPEG4 Part 10. Level 4 (HD).
DVB C2, T2 and H2 do not exist. The DVB are not developing them. Certainly DTT and Cable have higher order modulation methods available to them (QAM256 for example for DVB C) as part of their original spec. DVB S2 allows Higher order modulation settings not specified in the DVB S spec.

apparently DVB is working on the updates (kept that quiet didnt they LOL) no mention of DVB-C2 so far though that i can find at least?.

DVB wants new DVB-T and DVB-H standards by 2010
The DVB is preparing the ground for two major standards updates: DVB-T2 and DVB-H2, both of which are going to be closely interrelated, as the fixed terrestrial and mobile TV services they enable will be competing for the same UHF spectrum after analogue switch-off.
In each case, the standards will be designed to improve video delivery efficiencies. Although the specifications have to be defined, DVB-T2 (DVB-Terrestrial) is sure to make use of improved modulation techniques, as the new DVB-S2 (DVB-Satellite) standard has done in order to generate a 30 per cent increase in data throughput over a given bandwidth.
The DVB is not outlining efficiency targets but there is a view inside the organisation that major new standards like a new DVB-T should aim for a minimum 30 per cent improvement to make the effort worthwhile. There is an assumption that when UHF spectrum is made available after analogue switch-off, it will be extremely valuable."
"
The DVB denies that the introduction of DVB-H2 is a 'competitive' response to other mobile TV delivery standards/specifications, which have gained support over the last two years. According to MacAvock, the major focus is on DVB-T2 but because mobile services will compete for, and possibly use the same UHF spectrum, it is natural to develop the next version of DVB-H at the same time. He views the future use of UHF spectrum as a single, integrated issue , with the requirements for over-the-air HDTV, standard-definition television and TV-to-handhelds wrapped together."
like i said elsewere, it seems to me that NTL:tw/virgin use of that other cheaper for the bussiness end option their going to use will be another TVdrive white elephant ....
"
DVB-T2 is also viewed as a post switch-off technology - not a solution for existing terrestrial TV services. Analogue switch-off relies on mass consumer migration to digital terrestrial services and that needs very low-cost DVB-T set-top boxes in the market. Invariably, new technologies are considerably more expensive than old."
i dont think i could be convinced that that comment is the right way to look at it, sure the bean counters can justify it im sure, but look at what happened with most of the current DVB-T STBs, they droped in price like a stone because they didnt have the needed options or the ability to be flash upgraded, and all for a simple and cheap PFGA chip that could have been included as standard in the base developer unit that all the commercial boxs took as their product and they didnt see fit to add that option themelves.
its a simple thing in the long term, put all the needed options and the ability to updrade it in the field on all the initial units and in time the box costs will fall without loosing the future codec and user options that might be available later.
