"Whoa, we didn't see this one coming, but in an announcement today, the international Advanced Television Systems Committee approved and published an update (A/72) to the spec we all use for over-the-air HD that includes the hottest new codec around, H.264. The problem is that the odds of the US adopting the new standard with ATSC 1.0 so wide spread, is slim to none. It makes sense if you think about it, we aren't even done using NTSC yet, so the last thing every broadcaster in America wants to do now, is to go and replace all those modulators again. And it goes without saying that all the consumers aren't rushing out to replace all the tuners in our brand new HDTVs. So while it may be some time before the we adopt a new standard in the US, the rest of the world that chooses the new standard when they switch digital can at least enjoy more HD, with less bandwidth."^^<http://www.w3.org/2001/XMLSchema#string>
