My father in law built a few house and was sold a lexcom wiring system by a company. He got a silver box, so he says, and they made a claim that this box would allow him to "mirror" whatever was showing on his TV, to another TV in the house, over CAT5.
I am not aware of any technology that does this (Since I don't think you can broadcast tv over ethernet into the ethernet port of a TV), however, I do know you can transport HDMI over CAT5e and CAT6 and I am wondering if that is what they were talking about. The old company that did it is no longer around (surprise!).
I'd have imagined there would be all sorts of issues with resolutions, HDCP etc?
Anyone have any experience with it?
Sorry for being vague.
