System for recording digital information including audio information
View Patent ↗In recording audio information, an information medium in a format obtained by expanding the RTR (recordable/reproducible DVD) standard is used. For management information about each piece of information recorded on the information medium, an “audio information cell” is defined as a playback unit even for audio information as in the RTR standard. To a PGC (program chain) higher in level than the cell, “playback sequence” information about the relationship between other video information (movie cells) and/or still picture information (still picture cells) is given.
