Upline TV channel feed
I have multiple TVs throughout the house and want to have webTV accessable on all of them individually, but from a single source. Is there some kind of device I can use, connected just after the cable source and upline from all splits, that would allow me to override a channel with my own input?
In other words, if my daughter in her room wants to watch cartoons, she'd just put a regular TV channel on. If my son in his room wanted to watch a web broadcast, he'd flip to channel 3 and see whatever was being fed from the upline source (which would have input from the PC).
Is there such a device?
