Disney has announced a service called Moviebeam which will deliver "VOD" movies to consumer homes via analog broadcast tv signals using datacasting technologies. The service requires a side-car TV settop box that will apparently have enough [PVR-like] memory to store up to 100 movie titles [~150 to 200 GB]. Disney plans to test the service in Salt Lake City apparently via its ABC affiliate station there.
This brings up the interesting question again about whether or not cable operators are obligated to carry the "datacasting" information embedded in the ABC television signal and thus to enable the use of Cable's network to compete with their own VOD services without any compensation from a broadcaster like Disney?
