Forgive the rather crude diagram.
Pics from inside the cabinet might not help you.
Bedroom TV has an hdmi wireless receiver. The transmitter is in the TV cabinet in the kitchen and sits AFTER the four way HDMI splitter.
This way hd sat from the single receiver in the kitchen feeds all devices via the HDMI connections. Even the digital off air antenna plugs into the dish receiver and puts the local channels on the HDMI. This One To Many concept requires all sets watch the same thing.
However if my wife wants to watch something different in the bedroom on a local station she can still do that. And because by bedroom TV is a combo built in Dvd she can watch DVDs in there too.
ignore the stuff on the right at just shows how the power is run from the inverter.
