Sound and image transmission system |
摘要 |
A sound and image transmission system which is applicable to television-telephony, uses a single transmission line and multiplexes the image signal and the sound signal with an output which is essentially identical to the rhythm of an encoded image and the sound of the latter image. The encoder and decoder for the image processing lines function for only part of the time, but faster than if they functioned continuously.
