摘要：A compressively-encoding-resultant video signal resulting from compressivelyencoding a video signal, a first compressively-encoding-resultant audio signal resultingfrom compressively encoding a first audio signal having a synchronized relation with the
video signal, a reference clock information signal relating to synchronization between thecompressively-encoding-resultant video signal and the first compressively-encoding-resultant audio signal, and an indication timing information signal designating anindication timing of the video signal are multiplexed to get an AV multiplexing-resultantsignal. A second audio signal is compressively encoded to get a second compressively-encoding-resultant audio signal. A sound-production-timing information signal is addedto the second compressively-encoding-resultant audio signal to get a substitutionplayback audio signal. During playback, the substitution playback audio signal can bereproduced instead of the first audio signal while being synchronous with the videosignal. The sound-production-timing information signal responds to the reference clockinformation signal, and relates to synchronization with the video signal.
