TRANSMISSION SYSTEM FOR PICTURE AND VOICE

摘要

PURPOSE: To make the delay of an image which results from tampon memory 1/2 and to automatically delay a sound by sequentially transmitting an image and a sound at two times rate instead of parallelly transmitting them with two lines. CONSTITUTION: An output of an image encoder 14 and an output of a sound encoder 34 are connected to inputs 51 and 52 of a multiplexer 50 respectively. An output 53 of the multiplexer 50 has a cycle T=Ti+Ts which consists of an image signal having a duration time Ti and a sound signal having a duration time Ts. The output 53 is inputted 57 to a demultiplexer 56 by one transmission line 54. Then, an output 58 of the demultiplexer 56 is inputted to an image processing circuit 22, and this system operates T/Ti times faster (e.g. at two times rate) than when it always operates. Also, an output 59 of the demultiplexer 56 is inputted to a sound processing circuit 38, and it operates T/Ts times faster (e.g. at two times rate) than usual.
