1. An audio-visual display system comprising:
- A) a remote control transmitter having means for sending command codes to an audiovisual display unit, including;
1) first and second remote control operating modes for sending respective first and second remote control command codes to operate an audio-visual display unit;
2) the first and second command codes being activated by a first single button on the remote control transmitter;
B) the audio-visual display unit operated by the remote control transmitter, the audio-visual display unit having;
1) means for receiving and acting upon the first and second remote control command codes sent by the remote control transmitter;
2) first and second audio-visual display unit display types responsive to the first and second remote control command codes, respectively;
3) first and second signal source inputs, with the first display type being operable only on the first signal source input;
4) signal source input source selection means operable to determine the signal displayed; and
5) translation means for operating the audio visual display unit in its second display type when the remote control transmitter transmits the first remote control command code and the signal source input selected is other than the first signal source input.

Abstract
A television display system having a remote control unit which sends different command codes, upon activation of the same button, dependent upon which mode the remote control unit is in; has a simplified operation by translating a noneffective command code from the transmitter into an effective command at the display unit when the display unit is not in a signal source which can act upon the noneffective command code. Further simplifying the keypad operation of the remote control transmitter by allowing function and adjustment keys to perform double duty depending on the operating mode of the display is also discussed.
