There are a couple of ways of handling this. IPTV can be MPEG4 exclusively, since the older boxes can't handle it anyway. Also, with switched video, you can get the stream your PVR can use or, with all the extra bandwidth freed up from analog, just have both versions on the cable. This sort of thing is already happening, where you can get both HD and SD on the same channel number.
Certainly, and my understanding is that the IPTV will be mpeg4. Well as for HD and SD on the same channel, that I believe is actually a trick in the cable box, where the HD boxes are told to tune the HD equivalant stream if you select the SD channel number. Both streams exist (well maybe, the switching could mean they don't at any given time) and the box just has to tune the right stream. -- Len Sorensen
