Web TV: IPTV Or TV Over IP?

Om Malik has a detailed piece looking at the differences between IPTV and television over IP and suggests that the the fortunes might be favoring the latter

IPTV, is the technology
that is being deployed by phone companies either over copper or fiber
networks to replicate (and perhaps enhance) a television experience
normally available on cable networks…. Television over IP, on the other hand is the high quality streaming
video, that is made available over the fast pipes, without a set-top
box. This is a (comparatively) fairly low cost, and perhaps a simpler
model.
