Abstract

A signal reproduction apparatus such as an audio apparatus consists of a plurality of devices including a receiver. The receiver receives a broadcast wave signal (such as an FM signal) which includes a primary signal, along with data (such as RDS data) relating to a broadcasting station, a program, etc. transmitted together with the primary signal. The receiver includes a tuner circuit for receiving the broadcast wave signal, a decoder circuit and a signal generation device. The decoder circuit extracts the data (such as RDS data) relating to the broadcasting station and the program from the broadcast wave signal received by the tuner circuit. The signal generation device generates a remote control signal based on the data output from the decoder circuit, and outputs the generated remote control signal. The audio device includes a receiving section for receiving the remote control signal output from the signal generation device. The operation of the audio device is controlled based on the control signal output from the signal generation device of receiving section.

Claims

1. A signal reproduction apparatus comprising:

an audio device;

a receiver for receiving a transmission signal which includes a primary signal, and data relating to a broadcasting station and a program transmitted together with the primary signal, said receiver comprising;

a tuner circuit for receiving and demodulating the transmission signal;

a decoder circuit for extracting the data relating to the broadcasting station and the program from the transmission signal received by the tuner circuit;

a signal generation device for generating a remote control signal based on the data output from the decoder circuit, and outputting the generated remote control signal; and

an input section to be used for setting an operation state of the audio device; and

a control circuit for comparing a preset condition set through the input section with the data output from the decoder circuit and for supplying a control signal to the signal generation device when the data output from the decoder circuit coincides with the preset condition; and

the audio device including a receiving section for receiving the remote control signal output from the signal generation device, and for controlling an operation of the audio device based on the remote control signal;

wherein the signal generation device generates a remote control signal based on the supplied control signal, and supplies the generated remote control signal to the audio device; and

wherein when receiving, from the decoder circuit, data representing a prescribed broadcast with the audio device in a power-off state, the control circuit causes the signal generation device to output a remote control signal for turning on a power of the audio device.

2. A signal reproduction apparatus comprising:

an audio device;

a receiver for receiving a transmission signal which includes a primary signal, and data relating to a broadcasting station and a program transmitted together with the primary signal, said receiver comprising;

a tuner circuit for receiving and demodulating the transmission signal;

a decoder circuit for extracting the data relating to the broadcasting station and the program from the transmission signal received by the tuner circuit;

a signal generation device for generating a remote control signal based on the data output from the decoder circuit, and outputting the generated remote control signal; and

an input section to be used for setting an operation state of the audio device; and

a control circuit for comparing a preset condition set through the input section with the data output from the decoder circuit and for supplying a control signal to the signal generation device when the data output from the decoder circuit coincides with the preset condition; and

the audio device including a receiving section for receiving the remote control signal output from the signal generation device, and for controlling an operation of the audio device based on the remote control signal;

wherein the signal generation device generates a remote control signal based on the supplied control signal, and supplies the generated remote control signal to the audio device; and

wherein when receiving, from the decoder circuit, data representing a prescribed broadcast with the audio device in a first reproduction state for reproducing something other than the prescribed broadcast, the control circuit causes the signal generation device to output a remote control signal for controlling the audio device stop the first reproduction state and to start a second reproduction state for reproducing the prescribed broadcast.

3. An audio signal reproduction system for reproducing broadcast signals as sound, the system comprising:

a tuner circuit for receiving broadcast composite signals, the composite signals including a primary signal and a secondary digital signal;
