Abstract:
1. An after-recording apparatus comprising: first means for compressively encoding an audio signal into encoding-resultant audio data divided in units; second means for compressively encoding a video signal into encoding-resultant video data by using MPEG encoding method divided in units; third means for adding an audio time stamp for audio-vide audio-video synchronous reproduction to every unit of the encoding-resultant audio data generated by the first means to generate time-stamp-added audio data; fourth means for adding a video time stamp audio-video synchronous reproduction to every unit of the encoding-resultant video data generated by the second means to generate time-stamp-added video data; fifth means for multiplexing the time-stamp-added audio data generated by the third means and the time-stamp-added video data generated by the fourth means into main data by using MPEG multiplexing method; sixth means for, to first after-recording-purpose encoding-resultant data for at least one of encoding-resultant audio data generated by the first means and the encoding-resultant video data generated by the second means which form the main data, adding a time stamp for reproduction synchronous with a portion of the main data and identification information for identifying the after-recording-purpose encoding-resultant data to convert the encoding-resultant audio data in main data into after-recording-purpose encoding-resultant data; and seventh means for recording the main data, the after-recording-purpose encoding-resultant data, and play list information on a recording medium, the play list information by number of play items providing link between the main data and the after-recording-purpose encoding-resultant data.
