Abstract:
The present invention enables audio data to be recorded or played back more easily. LPCM samples from an LPCM sample 301-1 of a first channel to an LPCM sample 304-1 of a fourth channel in audio data are combined in order to generate a GOLS 310-1. An even number of GOLS are combined to generate an audio frame. Header information is added to the audio frame to generate an audio PES packet, which is multiplexed with a video PES packet and recorded onto a recording medium. As a result, the number of bits of the audio frame is an integral multiple of 32. This increases an affinity with a recording and playback apparatus.
