INFORMATION STORAGE MEDIUM FOR RECORDING AUDIO STREAM MIXING INFORMATION

摘要

PURPOSE: An information storage medium for recording audio stream mixing information is provided to mix different channel components without changing a channel structure of different audio streams, and to reproduce the mixed components, then to dynamically change the channel components, thereby supplying adaptive audio contents. CONSTITUTION: A decoder(1) decodes audio streams including plural audio data obtained from plural channels, respectively. A mixer(2) mixes the decoded audio data in reference to mixing information. The mixer(2) controls an output level of the audio data of mixing target channels in reference to the mixing information, and adds an output of audio data of at least one channel to an output of audio data of at least one channel that configures different audio streams. If plural mixing information contents are generated, the mixer(2) performs an adaptive mixing process for one audio stream.
