Embodiment Construction

[0051] Embodiments of the present invention for achieving the first object will be described below.

[0052] figure 1 The configuration diagram of Example 1 is shown. In the figure, first N (N is an integer greater than or equal to 1) still pictures (VOB) (1) coded by the above-mentioned MPEG I-picture etc. are collected as a still picture group (VOBG) (2). Control the time when the number of still pictures (1) in the still picture group (VOBG) (2) reaches a certain value (for example, 64, etc.) during still picture recording, and the time when the action mode is switched from animation pictures to still pictures, The next still picture group (VOBG) is generated (2). The data (coded stream data) of the still picture (VOB) (1) is recorded on the recording medium as a VOB file (11) described later, and the information for defining the still picture group (VOBG) (2) is recorded as a VOB management file ( 12) Recording on a recording medium.

[0053] The VOB management file (...

Abstract

A computer readable storage medium being capable of recording a large amount of still picture data thereon, allowing users to make a search based on recording times, and reducing the data size of recording time information, a recording apparatus, and a playback apparatus. When recording still pictures on a large-capacity storage medium, management information on recording times becomes so large that it becomes hard for the recording apparatus and the playback apparatus to process. To minimize the amount of data for managing still picture recording times, N (N is an integer equal to or larger than still pictures are grouped and, for each group, a first still picture recording time and a last still picture recording time are recorded as management information.

Description

[0001] This application is a divisional application of the application No. 99117504.2 with the filing date of August 6, 1999. technical field [0002] The present invention relates to a rewritable recording medium, a recording device and a playback device thereof, a recording method for the recording medium, and a computer program for realizing the recording method. It is especially suitable as a recording medium for an optical disc on which a large amount of still picture data is recorded. Background technique [0003] With the advent of optical disc recording media capable of large-capacity rewritability, such as DVD-RAM and DVD-RW, the development of technologies for recording data such as images and audios therein has sprung up. As video data, generally, data encoded by the MPEG (Moving Picture Experts Group) method described in the ISO / IEC11172 standard and the ISO / IEC13818 standard or the like is used. As the still picture data, generally, intra-coded data (I picture)...
