Embodiment Construction

[0025] In order that the present invention may be fully understood, preferred embodiments thereof will now be described with reference to the accompanying drawings.

[0026] A high-density optical disc such as a Blu-ray ROM (BD-ROM) according to the present invention may have a file or data structure for managing reproduction of video and audio data as shown in FIG. 2 . Many aspects of the data structure according to the present invention as shown in FIG. 2 are the same as the BD-RW standard discussed with reference to FIG. 1 . These directions are therefore not described in great detail.

[0027] As shown in Figure 2, the root directory includes at least one DVP directory. Among other things, this DVP directory includes: general information file info.dvp, menu files menu.tidx and menu.tdt1, stored with playlist files (such as real ( * .rpls) and virtual ( * .vpls)), the PLAYLIST (playlist) directory stores clip information files ( * .clpi), and A / V stream clip files ( * ...

Abstract

The recording medium includes at least one navigation area storing navigation management information for managing reproduction of the multiple reproduction path video data recorded on the recording medium. The navigation area has a plurality of angle change recording information corresponding to each of a plurality of data blocks.

Description

technical field [0001] The present invention relates to a recording medium having a data structure for managing reproduction of at least a plurality of reproduction path video data recorded thereon, and methods and apparatuses for reproduction and recording. Background technique [0002] Standardization of new high-density read-only and rewritable optical discs capable of recording large amounts of high-quality video and audio data is rapidly advancing, and new optical disc-related products are expected to appear on the market in the near future. Blu-ray Disc Rewritable (BD-RW) is an example of this new type of optical disc. [0003] Fig. 1 shows the file structure of BD-RW. As shown, the data structure includes a root directory containing at least one BDAV directory. This BDAV directory includes: files such as "info.bdav", "menu.tidx" and "mark.tidx", storing playlist files ( * .rpls and * .vpls) PLAYLIST (playlist) subdirectory, which stores clip information files ( *...
