RE: AT&T: 15 Mbps Internet connections "irrelevant"
Simon: Our regional head-end is adding MPEG4 in the next 3-6 months, so we're on the same bandwagon. Unfortunately, we've spent $$$ on MPEG2-only STB. It looks like we could be transport MPEG2 and MPEG4 around our local transport rings for a long time. We'll use the MPEG4 for customers who want HD, the rest will get upgraded as we can afford to. We have a few customers that have 4 or 5 TVs and want STBs for each one of them, and besides the fact that we have difficulty getting 20 Mbps on medium-range loops, we end up installing two modems because our BLC infrastructure is only configured for three streams. This will hopefully be resolves in future releases. Yes, there are quite a few MPEG4-capable STB vendors with lots of middleware vendors standing behind them, but I challenge you to document one STB/middleware combination in GA. I haven't seen it. Talk to me in six months, and it will be a different story.

I disagree. There are several MPEG4 capable STB available now, and they all have support of middleware vendors. > SD MPEG-2 runs around ~4 Mbps today and HD MPEG-2 is ~19 Mbps.

FTTP/H is 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 with ADSL2+ deployments (unless you want more than one STB per DSL).
