ABSTRACT:
An image signal transmitting and receiving system for encoding image signals to be transmitted from a transmission side to a receiver side and for decoding the received encoded image signals at the receiver side is described wherein the transmission side includes an object image extracting circuit, encoding circuits for object and background images and a multiplexer, and the receiver side includes a demultiplexer, decoding circuits for object and background images and an image combining circuit. Input image signals are divided into object background signals at the extraction circuit and then are respectively encoded at the encoding circuits. The encoded object and background signals are transmitted by way of the multiplexer and respectively input to the object and background decoding circuits through demultiplexer to provide respective decoded signals. The decoded signals are combined at the combining circuit to provide the whole image signals corresponding to the input image signals.
