Signal transmission system, signal transmitter, and signal receiver

A signal transmission apparatus connected to a signal reception apparatus through a transmission path, comprising:

• a time-base compression means for time-base-compressing an audio signal;
• and
• a signal multiplexing means for time-division-multiplexing a video signal, a control signal which is used for control at the signal receiving end, and the audio signal which is time-base-compressed by the time-base compression means, and transmitting the multiplexed signal to the signal reception apparatus through the transmission path.

A signal reception apparatus connected to a signal transmission apparatus through a transmission path, comprising:

• a signal demultiplexing means for demultiplexing a signal in which a video signal, a control signal to be used for controlling the signal reception apparatus or a device connected to the signal reception apparatus, and a time-base-compressed audio signal are time-division-multiplexed, which signal is transmitted from the signal transmission apparatus through the transmission path, into the video signal, the control signal, and the time-base-compressed audio signal, respectively;
• and
• a time-base decompression means for decompressing the time-base-compressed audio signal.
