摘要
In a time division multiplexing transmission system for transmitting video signals and a plurality of channels of PCM-TDM audio signals alternately, the video and audio signals being divided into video and audio frames, each of which has an equal time duration of a predetermined unit frame period, and the video and audio signals being transmitted in a sequence of one video frame and subsequently first and second audio frames, two groups of audio signals are multiplexed in time division in the form of a PCM signal so as to form first and second signal series of PCM-TDM audio signals, each of which series contains a plurality of PCM frames having a PCM frame period equal to an integer ratio of a predetermined period of the horizontal synchronizing signal and including a plurality of PCM time slots to which the PCM-TDM audio signals are allotted in a predetermined PCM time slot sequence in which a real signal to be reproduced directly and a memory signal to be reproduced after temporary storage are gathered separately to one another, under control of a PCM synchronizing signal having a period equal to an integer ratio of the predetermined period, whereby the configuration of apparatus for regenerating synchronizing signals in a receiver can be simplified and also the receiver can be manufactured easily and cheaply.
