Problems solved by technology

[0010] However, for figure 1 In the data form shown, the address information is embedded in the MPEG program stream, making readout time-consuming
That is, in determining the readout address of the still picture, stream data is read out from the disk, the data is analyzed by the main CPU of the player, and then the address of the access point of the still picture is determined, thus delaying the readout operation

[0063] (1-1) Data structure

[0064] Here, the structure of data recorded and / or reproduced by the information processing apparatus in the first embodiment of the present invention is explained. figure 2 A simplified structure of a still picture application format on a recording medium used in a recording and / or reproducing system according to the present invention is shown. This format has a structure similar to the application format described in the aforementioned Conventional Example 2, and has two layers, PlayList (PlayList) and Clip (Clip), for overseeing AV streams.

[0065] In the present first embodiment, a pair formed by a still picture group (picture file group) as a still picture set composed of one or more source groups and its auxiliary information is regarded as one object, which is referred to as clip unit to manage. Auxiliary information (image attribute information) of a still picture group is called clip information.

[0146] Next, a third embodiment of the present invention will be described. In this third embodiment, if the playback time of still images is predetermined as described above Figure 4 The first embodiment of the slide show or just specify the playback order of the still images Figure 7 or Figure 16 The playback control information designating a single playback path as a single play item, and a plurality of play items corresponding to the number of scenes or pages are provided, as described for scenes or pages in a slideshow of . The structure is similar to the structure of the play item in the information processing device described in prior art example 2 by employing each play item to represent a playback path (one playback domain), in prior art example 2, providing Playback domains of AV streams (play items represented by a pair of IN-point (in point) and OUT-point (out point) on the time axis) arranged into groups are defined, thereby further improving compatibility. ...

Abstract

An information processing device, which works as a recording device, creates a Clip Information file of a still image file (TS file) composed of a plurality of still images, creates a Playlist composed of a plurality of PlayItems indicating the reproduction path of a slide show, and records this information and the TS file on a DVD. The Clip Information file includes an EP_map, which is a table indicating the correspondence between the values of presentation type stamps PTS of the TS and the source packet numbers SPN in the TS indicated by the values. An information processing device, which works as a reproduction device, obtains the data addresses of the TS indicated by the Play Item reproduction start time, IN_time, and the reproduction end time, OUT_time, and reproduces still images by referencing the EP_map of the Clip Information and reading information therefrom.

Description

technical field [0001] The present invention relates to a recording medium having recorded thereon data composed of still images for a so-called slide show suitable for continuous reproduction of still images and auxiliary information thereof for recording and / or reproducing the data Information processing methods, information processing equipment and programs. [0002] This application claims Japanese Patent Application No. 2002-367235 filed in Japan on December 18, 2002, Japanese Patent Application No. 2003-067025 filed in Japan on March 12, 2003, and Japanese Patent Application No. 2003-067025 filed in Japan on May 9, 2003 priority of Japanese Patent Application No. 2003-132193, the entire contents of which are incorporated herein by reference. Background technique [0003] The DVD-Video standard has realized continuous reproduction of still images (so-called slide show). Each still picture signal is encoded into an intra picture (I picture) of MPEG2 (Moving Picture Exp...
