ABSTRACT:
A video coding apparatus receives a video signal containing moving-picture information, together with other information present in certain horizontal scanning lines in the vertical blanking intervals. The video coding apparatus compresses the moving-picture information into a compressed digital video data stream, assembles the other information into packets, and multiplexes the packets with the compressed digital video data stream to generate an output signal. A video decoding apparatus demultiplexes this signal to separate the packets from the compressed digital video data stream, decompresses the compressed digital video data, and outputs a video signal having information obtained from the packets in certain horizontal scanning lines in the vertical blanking intervals, and decompressed moving-picture information in other horizontal scanning lines.
