Abstract
A coding apparatus of the present invention comprises coding circuit 1 for audio signals, coding circuit 2 for video signals, interface circuit 3 on input of scene data, coding circuit 4 for scene data, composition circuit 5, multiplexing circuit 6, display circuit 7 and clock generating circuit 8. Each of coding circuits 1, 2 and 4 outputs time information representing a decoding timing, and composition circuit 5 outputs time information representing a composition timing. Multiplexing circuit 6 multiplexes time information together with the compressed data given from each of coding circuits 1, 2 and 4, thereby generating a bit stream.
