SIGNAL TRANSMITTING DEVICE AND SIGNAL RECEIVING DEVICE

摘要

A signal transmitting device which uses a multiplex unit (102) to multiplex image signals and time-axis-compressed voice signals based on multiple control signals, and transmit them via a data line (106); and a signal receiving device which uses a separation unit (103) to separate image/voice multiplexed signals received via the data line (106) into the original image signals and voice signals using separation control signals. In addition, horizontal synchronous signals or vertical synchronous signals of image signals are used as multiple controls signals and separation control signals; and voice signals are time-axis-compressed on a transmitting side, multiplexed into gaps between video signals, and are time-axis-expanded on receiving side. The signal transmitting device and the signal receiving device constructed as above can implement a DVI standard-compliant signal transmission system that can transmit image signals along with voice signals.
