Abstract

A remote control system for an audio/video system has a first remote controller for transmitting a first remote control signal for designating and operating one of the A/V devices. In accordance with the first remote control signal, an operational mode for a designated A/V device is set. A second remote control signal transmitter is provided for transmitting a second remote control signal for operating the designated A/V device in accordance with the set operational mode.

Claims

1. A remote control system for an audio/video system including a plurality of audio/video (A/V) devices, comprising:

a) first remote control signal emitting means having a plurality of switches for emitting a plurality of first remote control signals, each of which is provided for designating and for operating one of the A/V devices; and

b) an A/V system control unit for controlling said plurality of A/V devices including

1) receiving means for receiving each of the first remote control signals,

2) code determining means responsive to a first remote control signal received by said receiving means, for determining a designation code for each of said A/V devices designated by said first remote control signal,

3) operational mode setting means, having means for storing a plurality of sequential operation signals and being responsive to said designation code, said operational mode setting means for setting a sequential operation signal which sequentially operates each designated A/V device and any A/V devices associated therewith, and

4) second remote control signal emitting means for emitting a second remote control signal dependent on the set sequential operation signal which sequentially operates the designated A/V device and any A/V devices associated therewith in accordance with the set operation signal.

2. A system according to claim 1 wherein the operational mode setting means has means for deriving one of the operational modes in accordance with the received first remote control signal.

3. A system according to claim 1 wherein each of the first remote control signal emitting means and the second remote control signal emitting means is a remote controller for emitting the signal by means of light.

4. A system according to claim 1 wherein the A/V system control unit has means for emitting a received first remote control signal without modifying the received first remote control signal.

5. A system according to claim 1 wherein the A/V system control unit has an independent light emitting means connected thereto through a transmission means.
