摘要:
The invention relates to a recording medium, a corresponding recording apparatus and a corresponding reproducing apparatus. On the recording medium data are recorded as a sector and the sector is composed of a plurality of frames. The recording medium comprises a synchronous pattern disposed at a first portion of each of said frames, whereby the synchronous pattern represents a frame synchronization. Furthermore, a signal pattern is disposed at the first frame of the sector and adjacent to the synchronous pattern, whereby the signal pattern represents a delimitation of the sector.

In this invention, an information recording/reproducing apparatus (1) has an authentication function and directly transfers information to an MPEG board (134), sub-picture run-length board (135), speech coding/decoding board (136) without using a main CPU (111). Thus, information transfer between the information recording/reproducing apparatus (1) and various processing boards (134, 135, 136) can be performed without using a main controller (111), the load of the main CPU (111) can be alleviated and the main CPU (111) can perform another process during the information transfer period.

摘要:
A recording medium and a method for recording a signal on the recording medium having a first frame and a second frame, the first frame including a first synchronous pattern (23,24), a second synchronous pattern (25) that follows the first synchronous pattern and first data (25-33), the first data being modulated into RLL code, the second frame including the first synchronous pattern (41,42) and second data, the second data being modulated into the RLL code, one sector of the recording medium being composed of at least one first frame and a plurality of second frames, wherein a pattern that includes the maximum code inversion length of the RLL code and that does not correspond to a modulation rule of the RLL code is recorded as at least part of the first synchronous pattern, and/or wherein a first pattern that includes a plurality of successive sequences of the minimum code inversion length of the RLL code and that does not correspond to a modulation rule of the RLL code is recorded as at least part of the second synchronous pattern.

摘要:
Video data divided into a plurality of cells, attribute information for specifying the playback order of the plurality of cells, and a flag for specifying whether the playback can be effected or not for each of the plurality of cells are recorded on an optical disk. In a playback apparatus, the cell which is specified to be inhibited from being played back by the flag is not played back when a plurality of cells are played back based on the playback order specified by the attribute information.
