Abstract

An information recording medium includes a first area (DA2) for storing picture data for forming a plurality of pictures, a second area (DA21) which is included in the first area and stores control data of the picture data, and a third area (INFO1) which is included in the second area and stores specifying data for specifying the storage position of representative picture data for forming a representative picture in the plurality of pictures.

Claims

1. An information recording reproducing apparatus for reproducing a representative picture recorded on an information recording disc, wherein the information recording disc includes a first area of a managing file in which management information is stored and includes a second area of an audio file or a video file in which video information is stored, the information recording disc having at least one object recorded in the audio or video file and management information recorded in the managing file, said object including object units, said object units each include at least one of a video pack in which video data is recorded and an audio pack in which audio data is recorded, and said management information includes a plurality of program chain information, cells, disc representative picture information for one disc representative picture, and a plurality of chapter representative picture information respectively prepared for said plurality of program chain information, said plurality of program chain information designate respective cell reproduction orders, said cells represent portions of the object, said disc representative picture information includes information regarding a program chain number, a cell number and a picture point as a presentation time of a picture representing recording contents of the disc in the object unit, and information regarding a time when the disc representative picture was made, and each of said plurality of chapter representative picture information include respective picture points for representative frames for the chapter representative pictures, the information recording reproducing apparatus comprising:

means for displaying the chapter representative pictures as print targets according to a control signal from a remote controller; and

means for instructing a printer to print the chapter representative pictures when a print target chapter representative picture is designated.

2. An information recording reproducing apparatus according to claim 1, further comprising:

means for successively skipping to the picture points and for playing back the chapter representative pictures.

3. An information recording reproducing apparatus according to claim 2, further comprising:

means for starting play back of a moving picture from a chapter corresponding to the target chapter representative picture when a control signal for designating the chapter representative picture is received.

4. An information recording reproducing apparatus for reproducing a representative picture recorded on an information recording disc, wherein the information recording disc includes a first area of a managing file in which management information is stored and includes a second area of an audio file or a video file in which video information is stored, the information recording disc having at least one object recorded in the audio or video file and management information recorded in the managing file, said object including object units, said object units each include at least one of a video pack in which video data is recorded and an audio pack in which audio data is recorded, and said management information includes a plurality of program chain information, cells, disc representative picture information for one disc representative picture, and a plurality of chapter representative picture information respectively prepared for said plurality of program chain information, said plurality of program chain information designate respective cell reproduction orders, said cells representing portions of the object, said disc representative picture information includes information regarding a program chain number, a cell number and a picture point as a presentation a time of a picture representing the recording contents of the disc in the object unit, and information regarding a time when the disc representative picture was made, and each of said plurality of chapter representative picture information include respective picture points for representative frames, the information recording reproducing apparatus comprising:

means for successively skipping to the picture points and for displaying the chapter representative pictures;

means for starting play back, based on program chain information, a moving picture from a chapter corresponding to the target chapter representative picture when a control signal for designating the chapter representative picture is received.
