The a/b connectors are for connecting satellite or cable to your TV. When they are connected together it carries the cable signal to all TVs. If you disconnect them and run the A to your receiver, you then run an hdmi cable from your receiver direct to the back of your TV. That gets you satellite signal on the one TV. Still have regular TV signal to all TV's. Just have to have them jumpered together to receive cable to all TV's.
