Device for multiplexing video signals

摘要

A video signal multiplexing device for generating a video signal of a quality corresponding to a generating bit rate x includes a receiver stage 4 simultaneously receiving different image signals Yi at the respective inputs 2. The bit rate yi of the received signals is less than the generating bit rate x. The received image signals are stored in the storage stage 5 and read out by the data retrieval stage 8 at the generating bit rate (x) for generating the video signal which is composed of successive time segments of the different image signals Yi. Cameras 17 generate the image signals, each camera storing image signals and transmitting the image signals at the bit rate yi to the inputs 2 in accordance with control signals from a processor.
