Abstract
To improve qualities of audio and picture signals by distributing adaptively the code quantities of audio codes and picture codes and by adopting variable rate audio coding. The audio/picture processing apparatus handles audio presence information, audio characteristics information, audio quality information, picture quality information, code quantity distribution information, and line capacity information. A code quantity control means decides the distribution of the audio and picture codes, an audio coding format, and a coding rate, whereby the audio signal and picture signal are coded by a picture encoder and an audio encoder. The outputs from the picture encoder and the audio encoder are multiplexed by a multiplexer in order to transmit a multiplexed bit stream onto the network.
