Wireless Broadcasting of TV channels
Why not have a TV receiver that can simultaneously translate up to 20 channels and send them wirelessly AKA broadcast them to the other TV's in the home. Room A wants to watch channel 2. Room A tunes their TV to channel 2 and the TV transmits to the receiver telling it to broadcast channel 2, therefore allowing the TVs in any room to receive channel 2. Up to 20 different TVs could tell the receiver to transmit a different channel. This would allow the simultaneous recording/watching of up to 20 channels in different rooms.
In addition allow any one TV to ask the receiver for up to five channels (for viewing and for recording), allowing you to record four channels simultaneously while being free to watch your TV program in real time all on one TV set.
If four TVs were each recording their max. of four unique channels and each of the four were displaying a unique program in real time, this would mean the receiver was broadcasting its maximum 20 unique channels.
Do I watch too much TV? No, but all the good stuff is on at the same time!
