Also, I think that the majority of IP TV deployments right now are not in the US.
in fact, you would be hard-pressed to find an MPEG-4 capable STB working with middleware.I disagree. There are several MPEG4 capable STB available now, and they allhave support of middleware vendors.
In the last IPTV trade show I went to (TVoDSL in Paris in January), I don't recall a single MPEG STB or IPTV system vendor who wasn't either showing or promising H.264 support.
SD MPEG-2 runs around ~4 Mbps today and HD MPEG-2 is ~19 Mbps. With ADSL2+ you can get up to 24 Mbps per home on very short loops, but if you look at the loop length/rate graphs, you'll see that even with VDSL2 only the very short loops will have sufficient capacity for multiple HD streams. FTTP/His inevitable.Anyone looking to do HD will be looking at H.264, and looking to bring the bandwidth requirement down to 8-10Mbps. That is certainly more practical withADSL2+ deployments (unless you want more than one STB per DSL).
Which you would in the US, but maybe not everywhere (yet).
