SOLUTION: A CPU 1 controls and also manages the acoustic control circuit 5, a communication control circuit 3, a large capacity memory control circuit 2 and a display means control circuit 6. This remote controller constitutes the remote control assembly of the audio visual reproduction system. Then, the remote controller is the remote controller using the radio frequency transmitter. The reproduction system is provided with the radio frequency receiver provided on the acoustic control circuit 5. The remote controller is provided with a means connected to a component, a counter for instance. The remote controller is not required to be directly turned to the reproduction system and it is not required to turn the transmitter to the receiver so as to use a radio frequency. |
