Abstract

A video multiplexor-encoder and decoder-converter includes a video multiplexor and encoder for selectively receiving, time-division multiplexing and encoding multiple video signals representing multiple video images for transfer and simultaneous display thereof in a selected pattern of multiple video windows on a video display device, and further includes a decoder and video converter for receiving, decoding and converting an encoded, time-division multiplexed video signal for selective, simultaneous display of the multiple video images in the selected pattern of multiple video windows on a video display device. The encoded, multiplexed video signal includes display control data which selectively represent a position, size and relative visibility priority for each one of the video images within the selected display pattern of multiple video windows.
