BOZ, Digital audio and component video can be distributed a few ways..First of course with price not being a factor,Crestron is very capable of sending audio/video/and digital inputs over cat5 up to 8 locations..To a breakout box commonly refered to as an RMC or room solution box.. Cost coming in to it channel plus a few years ago did say they were relesing some cool stuff,you will have to research this..Then audio control just relased a 2 box system that allows you send Component and digital over cat5 up to 1000 feet..Realizing of course you will need a pair per times you wish to distibute, and video amps of some kind as well.
