## Abstract

With this invention, at least one of a video file containing video information, a still picture file containing still picture information, and an audio file containing audio information and a management file having management information on a control method of reproducing the information in the file are recorded on an information storage medium. This realizes a data structure that causes the recording and deleting places on the information storage medium to correspond spuriously to places on a single tape, such as a VTR tape. Use of the data structure provides users with an easy-to-use interface.

## Claims

### Claim 1

A non-transitory machine readable information recording medium for access by an information reproducing apparatus, the non-transitory machine readable information recording medium comprising:
a first area configured to record a video file,
the video file including a video object, and
the video object including a video unit; and
a second area configured to record control information,
the control information including time information,
the time information including information relating to the video unit,
the control information specifying a first program chain, a second program chain and cells,
the first program chain designating first reproduction order of one part of the cells,
a first cell of the one part of cells referring to a first section of the video object,
the second program chain designating second reproduction order of another part of the cells,
a second cell of the another part of cells referring to a second section of the video object,
a part of the first section being able to overlap with the second section,
another part of the first section being able not to overlap with the second section,
the control information including program chain information representing the first program chain, and
the program chain information including information referring to the time information,
wherein
the video file is read by the information reproducing apparatus,
the control information includes information which relates to a specific time for playback, and
the control information is read and provided to play back the video file by the information reproducing apparatus, and the video file is accessed according to the read control information.

### Claim 2 (depends on 1)

An information reproducing method for reproducing information from the non-transitory machine readable information recording medium according to claim 1, wherein the information reproducing method comprises:
reading the control information; and
accessing and reproducing the video file based on the read control information.

### Claim 3 (depends on 1)

An information recording method for recording information on the non-transitory machine readable information recording medium according to claim 1, wherein the information recording method comprises:
recording a new video object on the non-transitory machine readable information recording medium; and
adding new information to the control information.

### Claim 4 (depends on 1)

The information reproducing apparatus for reproducing information from the non-transitory machine readable information recording medium according to claim 1, wherein the information reproducing apparatus comprises:
a unit configured to read the control information, and configured to access and to reproduce the video object based on the read control information.

### Claim 5 (depends on 1)

An information recording apparatus for recording information on the non-transitory machine readable information recording medium according to claim 1, wherein the information recording apparatus comprises:
a unit configured to record a new video object on the non-transitory machine readable information recording medium, and configured to add new information to the control information.
