Also I would expect as the HDV or other HD formats evolve that 50 or 100 mbs variants will emerge.  If you want to do high quality frame accurate editing of your video you don't really want to capture it in an MPEG format with P and B frames. You want the original in an all I frame format like DV.  That takes a lot more bandwidth.

Mike,

I was also add conventional (digital) consumer camcoders to your list.  It is my understanding that most of these still use DV, which is no where near as compressed as MPEG-2.  I realize that many camcorder manufacturers are moving to MPEG compressed format, but there are still a a lot of DV cameras out there.

It's not inconceivable that you may want to move this content on a home network without further compression.

Not speaking for Kevin, but based on earlier conversations with CE vendors,

1) Games (from console to display) ... currently only SD quality (that's

about 270 Mbit/sec in the US, as you noted) ... GigE can carry ... but the

next generation consoles support HD at 1080i or roughly 1.5Gbit/sec ...

2) Overlaying the UI from a STB or other residential gateway ... currently

3) Security/monitoring cameras ... although the fidelity requirements are

rather low, so cheap compressors are becoming available that meet this need

In the discussions so far, the digital video has been assumed to either

enter the residence from a service provider or originate in the residence at

a DVD player.  It seems that both cases, at least at present, use compressed

digital video.  Are there applications that involve uncompressed digital

video (or are there expected to be such applications)?
