Embodiment Construction

[0038] In order to fully understand the present invention, exemplary embodiments thereof will now be described in detail with reference to the accompanying drawings.

[0039] A high-density recording medium according to the present invention, such as a high-density optical disc (for example, Blu-ray ROM (BD-ROM), BD-RE, etc.), may have a file or data structure for managing figure 2 Reproduction of the video and audio data shown in . as in figure 2 Several embodiments of the data structures of the present invention shown in are similar to those represented by figure 1 BD-RE standard shown. Examples such as these will not be discussed in more detail here.

[0040] as in figure 2 As shown in , the root directory includes at least one DVP directory. The DVP directory includes a PLAYLIST directory in which the general information file info.dvp, menu file menu.tidx, especially menu.tdt1, playlist files (for example, real (*.rpls) and virtual (*.vpls) are stored, selected In...

Abstract

A method for recording a data structure used for managing the reproduction of video data in a recording media comprises the steps: recording video data including a first reproduction path and a secondreproduction path on the recording media; recording an excerption information file including the time information of the video data on the recoding media; recoding a first play list file and a secondplay list file on the recording media; and recording a navigation file on the recording media; wherein both of the first play list file and the second play list file comprise a play item representingthe play interval in the excerption of the video data, and the first play list file and the second play list file respectively represent the first reproduction path and the second reproduction path;the navigation file comprises a first path item and a second path item, wherein the first path item comprises a first navigation command used for starting the first play list file, and the second pathitem comprises a second navigation command used for starting the second play list file.

Description

[0001] The present invention is filed on November 19, 2003, and the application number is 200380100241.3 (the international application number is PCT / KR2003 / 002489), and the title of the invention is "Having a data structure for managing the reproduction of at least video data recorded thereon The divisional application of the international application for the recording medium and its recording and reproducing method and device". technical field [0002] The present invention relates to a method and apparatus for recording a data structure for managing the reproduction of video data on a recording medium. Background technique [0003] Standards for new high-density read-only and rewritable optical discs capable of recording large amounts of high-quality video and audio data have been rapidly developed, and related products of the new optical discs are expected to be commercially available in the near future. Blu-ray Disc Rewritable (BD-RE: Blu-ray Disc Rewritable) is an exam...
