Signal transmitter and signal receiver

摘要

A signal transmitter and a signal receiver comprises a time base compression part ( 101 ) for compressing an audio signal on a time base to output the compressed signal as a time base compressed audio signal and a multiplexing part ( 102 ) for multiplexing a video signal, a control signal, and the time base compressed audio signal to output the multiplexed signal to the external as a video/audio control multiplexed signal. The thus constituted signal transmitter and the signal receiver realize a signal transmission system for multiplexing and transmitting the video signal, audio signal, and control signal, for consequently transmitting high-quality diverse digital audio signals without conversion into an analog signal, and for transmission at high speed with minimal error.
