RF switching with remote controllers dedicated to other devices

Apparatus for selectively switching first and second signal sources along switching paths extensible to the input of a video recorder having an RF output and to the input of a television receiver, comprising:

• a switching circuit having:
• a first switch input connectable with said first signal source electrically coupled with a first switch responsive to a first control condition to provide an electrically closed condition along a switch path extending for connection with said input of said video recorder, and further electrically coupled with a second switch responsive to a second control condition to provide an electrically closed condition along a switch path extending for connection with said input of said television receiver,
• a second switch input connectable with said second signal source, electrically coupled with a third switch, responsive to a third control condition to provide an electrically closed condition along a switch path extending for connection with said input of said video recorder, further electrically coupled with a fourth switch responsive to a fourth control condition to provide an electrically closed condition along a switch path extending for connection with said input of said television receiver,
• a third switch input connectable with said RF output, electrically coupled with a fifth switch responsive to a fifth control condition to provide an electrically closed condition along a switch path extending for connection with said input of said television receiver;
• and
• a switch control responsive to actuating inputs for selectively providing said first, second, third, fourth, and fifth control conditions, said switch control deriving said fifth control condition to effect said fifth switch electrically closed condition and said second and third control conditions to effect an electrically open condition of said second and third switches when said first switch is in a said electrically closed condition, and said fourth switch is in an electrically open condition.
