Embodiment Construction

[0052] Embodiments of the present invention for achieving the first object will be described below.

[0053] figure 1 The configuration diagram of Example 1 is shown. In the figure, 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.

[0054] The VOB management file (VOBGI)...

Abstract

To provide an optical disk that records a huge amount of still image data, realizes retrieval based on its recording time and reduces a data size of recording time information, and to provide an optical disk recorder and an optical disk reproducing device. In order to minimize a data quantity to manage a recording time of a still picture, N (N is an integer of 1 or over) sets of still images are grouped and a recording time of a still image recorded at first for each group and a recording time of a still image finally recorded by each group are recorded as management information.

Description

[0001] The application number is 200410034238.2, and the application date is August 6, 1999. [0002] A divisional application of the invention patent application titled "Playback Device and Playback Method". technical field [0003] 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 [0004] 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 t...
