Regarding H.264 for HDTV via DVB-T, I understand that TVNZ (New Zealand) are about to utilize MPEG4 on our soon to be established DTTV platform for (presumably more channels of) SDTV via DVB-T in the new year. What other countries are utilizing MPEG4/H.264 for SDTV right now?
I dont think its so much about "countries" as it is about operators at this point.
If you call all DVB-T operators 100%, its probably 80% MPEG2 and the rest H264. (Just a SWAG).  I dont think there is much incentive to got to 264 you just buying equipment to begin with or you want to add HD and your current in MPEG2. 

Even with HD in DVB-T while you can get more content with 264, you can still operate with MPEG2 I believe.




Happy Christmas folks.

Hi boys, girls and lurkers (myself mostly nowadays....)

I don't mean to be rotten BUT I don't have a problem here.The debate on opendtv about ATSC/8VSB/COFDM etc is largely sterile and conducted by the same few protagonists with the same predictable vituperative exchanges (JW, BM, BM etc increasingly nasty, immature and silly to each other). And it is so f*************ing boring.

ATSC has lost commercially, strategically and technically. Nobody is interested in buying ATSC STBs in the US, outside the US (pace Canada, Mexico which are border states to the US), the business model has failed, and we will probably see NTSC carry on for many a long day. Elsewhere the plethora of COFDM systems (DVB-T, ISDB-T, T-DMB, DAB-IP. DVB-H, MediaFLO (carrying on the US tradition of pioneering OFDM), etc are doing very nicely...

It is clear, in spades, apart from to the usual Don Quixote windmill tilters on opendtv that ATSC/8VSB/the current US DTV business model is now the perfect trainwreck. And so completely over commercially.

The real issues for a viable OTA DTV service are:

a) Compelling content
b) Systems which work out of the box rather than engineering trainsets which might or might not work in the indeterminate future
c) Business models with consumer appeal. These tend to be free.
d) Comprehensive differentiation from cable + DBS through unique leverage of OTA distribution. That means no rotors, portable, mobile etc...

Outside the US this has been achieved in spades in many countries. The evidence is overwhelming and the common component is, quite naturally, xOFDM.  Of course there are some who will never learn until the NTSC customer is cutoff in his prime.

Kind Regards and compliments of the season,
