better codec's...

we need better codec's... heck Microsoft's WMV codec preserves great picture quality in HD and uses less space then MPEG-2... and MPEG-4 would be the best if you wanted a largely used standard... why in the world are we still using MPEG2? There are much better codec's out there for vidoe compression... DirectTV has the right idea, cable should follow for digital channels.

Because MPEG-4 isn't part of the ATSC or Digital Cable Ready (DCR) standards.

We're still using MPEG2 because of legacy equipment. Motorola just recently announced their first STB to fully support MPEG4 video and the ability to tune all the way up to 1GHZ. Also, the feed feeds coming off the satellites are MPEG2 still (for the most part) Transcoding from MPEG2 to MPEG4 would cause its own share of compression artefacts. I think we'll see a lot of providers using the 860Mhz-1ghz spectrum for MPEG4 video until all the set tops are capable of doing MPEG4. That could take a while.

Unfortunately Microsoft's WMV codec is very heavily ridden with license fee's and requires very proprietary equipment. Everyone will move to MPE4 instead.

Not only is it not currently the standard but it's also incompatible with most existing cable boxes.

My guess is the 750MHz-1GHz spectrum. Systems that don't have more than 750 MHz are more more likely to be upgraded sooner. The approximately 450 MHz used for analog will also be nearly cut in half.

kudos:1

System with less than 750mhz will probably never be upgraded, they are probably 1-way too, with you having to call a telephone number for PPV.
