A video signal, an audio signal, and a control signal to be used for control at the receiving end are time-division-multiplexed and transmitted. A signal transmission system is provided with a signal transmission apparatus (11) including a time-base compression unit (101) for time-base-compressing an audio signal, and a multiplexing unit (102) for time-division-multiplexing a control signal and the time-base-compressed audio signal in a blanking period of a video signal, and transmitting the time-division-multiplexed signal to a signal reception apparatus (12) through a transmission path (106); and a signal reception apparatus (12) including a demultiplexing unit (103) for demultiplexing the signal in which the video signal, the control signal, and the time-base-compressed audio signal are time-division-multiplexed, which signal is transmitted from the signal transmission apparatus (11), into the video signal, the control signal, and the time-base-compressed audio signal, respectively, and a time-base decompression unit (104) for decompressing the time-base-compressed audio signal.
