Embodiment Construction

[0023] In order that the present invention may be fully understood, exemplary embodiments thereof will be described in detail below with reference to the accompanying drawings.

[0024] A high-density recording medium such as a high-density optical disc (for example: Blu-ray ROM (BD-ROM), BD-RE) according to the present invention may include figure 1 A file or data structure for the reproduction of video and audio data as shown in. figure 1 Some aspects of the data structure according to the present invention shown in , are the same as those of the well-known BD-RE standard, so these aspects are reviewed and not described in detail.

[0025] Such as figure 1 As shown in , the root directory contains at least one BD directory. The BD directory includes general files (not shown), a PLAYLIST directory in which playlist files (eg: *.mpls) are stored, a CLPINF directory in which clip information files (*.clpi) are stored, and clip information files and STREAM directory of A / V st...

Abstract

The recording medium includes a data structure with presentation data stored in a data area of the recording medium. The presentation data is divided into still picture units with each still picture unit including at least one still picture and associated related data.

Description

(1) Technical field [0001] The present invention relates to a method and apparatus having a data structure for managing at least reproduction of still pictures recorded thereon, and recording and reproduction. (2) Background technology [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 progressing rapidly, and new optical disc-related products are expected to be commercially available soon. Blu-ray Disc Rewritable (BD-RE) and Blu-ray Disc ROM (BD-ROM) are examples of these new optical discs. [0003] Although the standard of BD-RE has been published, the standardization of high-density read-only optical discs such as Blu-ray ROM (BD-ROM) is still in progress. Therefore, an effective data structure for managing reproduction of still images recorded on a high-density read-only optical disk such as a BD-ROM has not yet been obtained.
