Abstract: A sub-picture category (SP_CAT) is added to a sub-picture unit header (SPUH) configuring a sub-picture unit, and a flag “Raw” indicating pixel data run length compression/non-compression is provided in the header. Original data with a 4-bit/1-pixel configuration is subjected to run length compression, and if the data after compression exceeds the size of the original data, flag “Raw”=1 (non-compression) is specified. If the data is slightly compressed, flag “Raw”=0 (compression) is specified, thereby enabling efficient recording of sub-picture information in a recording medium.

Abstract: The present invention provides an information recording method and an information recording apparatus, which are capable of recording reproduction controlling information in information recording medium such as DVD. An operation portion designates a division timing in the audio information in case of dividing continuous audio information to record it in the DVD. A pickup records the audio information before the designated division timing and the audio information after the designated division timing in the DVD. A system controller repeats generating object recording sequence information in associated with the audio information before and after the division timing, respectively, to record them in the DVD every time when the division timing is designated.

Abstract: In a button mode (BTN_MD), there is provided a flag (HDGR) indicating whether or not an HD button group is recorded, thereby switching the contents of the following button group display type (BTNGR#n_DSP_TY). When the flag HDGR=1 (when the HD button group exists), no button group coexists with a button group having a conventional SD normal aspect ratio (4:3). Thus, the use of a data structure is facilitated by allocating the HD button group to the flag.
