Embodiment Construction

[0023] In order to fully understand the present invention, examples thereof will be described below with reference to the accompanying drawings.

[0024] High-density optical discs such as Blu-ray ROM (BD-ROM), BD-RE etc. according to the present invention can have such figure 2 File or data structure shown for managing the reproduction of video and audio data. figure 2 Many aspects of data structures according to the present invention are shown in with reference to figure 1 The data structure of the discussed BD-RE standard is similar. As such, these aspects will not be described in detail.

[0025] Such as figure 2 As mentioned above, the root directory contains at least one DVP directory. This DVP catalog includes a general information file info.dvp, menu file menu.tidx, menu.tdtl etc., store the PLAYLIST catalog that play list file (for example, real (*.rpls) and imaginary (*.vpls)), store There is a CLIPINF directory of a clip information file (*.clip), and a STRE...

Abstract

The recording medium has a data structure for managing reproduction of at least multiple reproduction path video data recorded on the recording medium. A data area of the recording medium stores clip files of at least a video data stream, and each clip file is associated with one of a common reproduction path portion and a particular reproduction path portion of the video data stream.

Description

technical field [0001] The present invention relates to a recording medium having a data structure managing reproduction of at least multi-path reproduction path video data, and methods and apparatus for reproduction and recording. Background technique [0002] The standardization of new high-density read-only and rewritable optical discs capable of recording large amounts of high-quality video and audio data has been rapidly advanced, and related new optical disc products are expected to be launched on the market in the near future. Blu-ray Disc Rewritable (BD-RE) is one of these new discs. [0003] figure 1 Indicates the file structure of the BD-RE. This file structure or data structure is provided for managing reproduction of video and audio data recorded on the BD-RE. As shown, the data structure includes a root directory containing at least one BDAV directory. The BDAV directory includes files such as 'info.bdav', 'menu.tidx', and 'mark.tidx', a PLAYLIST subdirector...
