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?
It is or soon will be used by a number of systems in the U.S., but not
by ATSC broadcasters other than USDTV, which announced an H.264
adapted at NAB, and plans for a new STB that should be release about now.
I thought USDTV was gone, but now I see they are back in business.
I am almost afraid to ask, does anyone known whether signal reception at
customer premises was a big problem for them.
DirecTV is using H.264 in new STBs to deliver HDTV and I believe that
they will use H.264 for SDTV to add more markets for local into local.
Dish Networks is also migrating to H.264, presumably for HD
programming first.
I believe that all mobile TV operators will use H.264, but this may be
for "less" than SDTV quality.
Apple is using H.264 for video downloads from the iTunes store at 640
x 480 resolution (progressive scan), although widescreen material is
encoded at 640 x XXX lines (square pixel) based on the actual aspect
ratio - IMHO this is generally better than SDTV quality, but not quite
24P DVD quality.
Vongo is also H.264 (Windows VC1 actually)
