Jeremy,

Yes, SDV is similar to IPTV. Instead of sending all the channels into your home, your STB requests a specific channel and only that channel is sent over the SDV frequency. It is much like VOD, just transparent to the user.

But with one major difference.

IPTV runs over a IP packed switched network which means that it can more effectively use the total amount of bandwidth. SDV runs over normal QAM channels which share a single QAM channel, (just like VOD) which usually means more bits are wasted.
