Dish did have such a system to retransmit in ATSC to any and all HDTV's in the home on paper, and, I believe as a prototype. All one had to do was tune to the appropriate ATSC channel on the HDTV, and you had a whole home DVR system. But, yes, the content owners don't like ANY unencrypted retransmission of their content, and that was killed. Yes, OP, you are bright, but all the clever, elegant, and inexpensive whole home solutions have all be QUASHED by the content owners and providers. That's why it has take YEARS for DirecTV and Dish to finally get systems that pass muster with the content owners AND have economies that make sense.
