In a signal transmission apparatus and a signal reception apparatus according to the present invention, the signal transmission apparatus side comprises a time-base compression unit (101) for compressing an audio signal on the time axis to output a time-base-compressed audio signal, and a multiplexing unit (102) for multiplexing a video signal, a control signal, and the time-base-compressed audio signal to output a multiplexed video-audio-control signal to the outside. According to the signal transmission apparatus and the signal reception apparatus so constructed, a multiplexed video-audio-control signal can be transmitted. Therefore, it is possible to realize a signal transmission system which can transmit a large variety of high-quality digital audio signals without converting them into analog signals, and perform high-speed transmission with fewer errors.
A signal transmission apparatus comprising:
A signal transmission apparatus for transmitting RGB video signals as serial data, wherein a control signal for controlling a monitor or the like which is to be connected is multiplexed into a blanking section of a video signal in either one or all of the signal lines RED, GREEN, and BLUE, and the multiplexed signal is transmitted.
A signal reception apparatus for receiving a video-audio-control signal in which a video signal, a time-base-compressed audio signal, and a control signal are multiplexed, comprising:
A signal reception apparatus for receiving RGB video signals as serial data, wherein a control signal for controlling a monitor or the like which is to be connected, that is multiplexed into a blanking section of a video signal in either one or all of the signal lines RED, GREEN, and BLUE, is extracted.
