said by k9iua6:This sounds like something more complicated than it is worth. It would mean every TV has to be connected by a STB (or cable cards) sophisticated enough to alert the central distribution center as to what the user(s) wants to watch. All the more to break down and all the most costly to implement and maintain, meaning higher costs all around. I'd say no if I have the vote.
not really that hard it works the same as VOD only that all of the users on the node tune to different channels and if a channel is watched that is SDV it is only duplicated once so basically all of the channels that are watched on the node at the same time are the only channels sent out via SDV that are being broadcast out of the SDV pool. My TWC system uses 24 SDV QAMs and is 860MHz with 64 analogs.

The only problem with SDV is that you need to have a large enough customer base to deploy it and it takes about 90 days to implement.
