Signal transmission system, signal transmitter, and signal receiver

Abstract

A signal transmission system has a signal transmission apparatus including a time-base compression unit for time-base-compressing an audio signal, and a multiplexing unit for time-division-multiplexing a control signal and the time-base-compressed audio signal in a blanking period of a video signal. The signal transmission apparatus transmits the time-division-multiplexed signal through a transmission path. The signal transmission system also has a signal reception apparatus including a demultiplexing unit for demultiplexing the signal in which the video signal, the control signal, and the time-base-compressed audio signal are time-division-multiplexed. The multiplexed signal is transmitted from the signal transmission apparatus to the signal reception apparatus and demultiplexed into the video signal, the control signal, and the time-base-compressed audio signal, respectively, and a time-base decompression unit for decompressing the time-base-compressed audio signal.
