I do remember, years ago, that Dish was working on a whole home solution that would have used a central distribution device to send multiple HD signals to multiple rooms modulated in ATSC via coax cable for people to tune directly from the HDTV for access to satellite, but it was kaboshed because it was the broadcasters, who hold the license to the content, did not want ANY re-transmission in HD, certainly not any that was not secure. I believe this solution was killed before even the content providers had a chance to whine.
Similarly, Direc TV was working on its own whole home solution that would send HD signals to rooms through out the home which had a special box for reception. The signals were to be sent by wireless technology, but Direc TV could not make it sufficiently secure to the satisfaction of the content owners, so it, too, was kaboshed.
In other words, we would all have had fairly sophisticated whole home solutions years ago if it weren't for the paranoia and ignorance of the content owners, and, yes, the broadcasters, too.
