Problems solved by technology

[0007] In addition, in the conventional example, it is not considered that multiple users make selections and manage favorite playlist information.
For example, even if multiple users want to generate, select and manage their favorite playlist information, it is impossible to realize
In addition, in particular, the requirement for the user to select and manage any number of playlists within multiple playlists is not considered

Embodiment Construction

[0025] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 The management status of AV data on the recording medium in the recording and reproducing apparatus of the present invention is shown. 101 with figure 2 Similarly, 201 in the figure is the AV data itself on the recording medium, and shows the case where there are program #1 to program #3 as the recording unit.

[0026] 102 is equivalent to figure 2 202 in , here, shows the third management level (management level 3) of management information. Program information #1 to program information #3 show the entire reproduction range of program units of program #1 to program #3, respectively. In addition, program information #2a to program information #3a show the reproduction range of the whole or part of a program arbitrarily designated by the user, and here, a part of program #2 and a part of program #3 are respectively shown. In the places corresponding to progra...

Abstract

In order to provide a recording and reproducing device that allows a user to select and manage arbitrary play lists, a unit of management for managing all registered play list information and an upper management hierarchical level are added. The unit of management is adapted to be handled on the same level with unified information that indicates a reproduction range of all AV data. User-defined unified information is adapted to be handled on the added management hierarchical level. The user-defined unified information is formed to allow arbitrary reproduction ranges contained on a lower hierarchical level to be registered.

Description

technical field [0001] The present invention relates to a recording and reproducing apparatus for recording and reproducing data on a recording medium. Background technique [0002] With the development of high-efficiency coding technology, AV data such as images and sounds are converted into digital data to compress the code amount, making it possible to record in real time on large-capacity recording media such as hard disks and recordable optical discs. . In addition, in the recording and reproducing apparatus equipped with these recording media, when digital data is input from the outside in a state where the code size has been compressed by means of playback or communication, it is also necessary to record these digital data on the recording medium as they are. possible. [0003] In these recording and reproducing apparatuses, management information for managing digital data to be recorded is generated and correspondingly recorded on the same recording medium. In the...
