## Abstract

On an optical disk, video object sets (VTST_VOBS) to be reproduced and video title set information (VTSI) serving as management information on the video object sets have been stored. In each video object set (VTST_VOBS), many data cells, each containing video, audio, and sub-picture data, are arranged. Management information on programs chains, which are combinations of programs to be reproduced one after another, has been written in a video title set PGC table (VTS_PGCIT). By referring to the program chain table (VTS_PGCIT) according to the user's input, the playback order of program chains can be changed, enabling the program chains to be reproduced one after another in various modes.

## Claims

### Claim 1

A non-transitory computer readable information storage medium comprising:
video manager information; and
video title set information,
the video title set information comprising video title set menu language unit search pointers and video title set menu language units grouped for each language,
one of the video title set menu language unit search pointers comprising a video title set menu language code,
the video title set information comprising a video title set menu program chain information unit table information, and
the video title set menu program chain information unit table information comprising an end address of video title set menu program chain information unit table,
wherein one of the video title set menu language units corresponding to the video title set menu language code is acquired when the video title set menu language code equals to a language code of a player, and
a video title set menu language unit search pointer which differs from the one of video title set menu language unit search pointers is acquired when the video title set menu language code does not equal to the language code of the player.

### Claim 2

A method for reproducing information from a non-transitory computer readable information storage medium including
video manager information, and
video title set information,
the video title set information comprising video title set menu language unit search pointers and video title set menu language units grouped for each language,
one of the video title set menu language unit search pointers comprising a video title set menu language code,
the video title set information comprising a video title set menu program chain information unit table information, and
the video title set menu program chain information unit table information comprising an end address of video title set menu program chain information unit table,
the method comprising:
acquiring one of the video title set menu language units corresponding to the video title set menu language code when the video title set menu language code equals to a language code of a player, and
acquired a video title set menu language unit search pointer which differs from the one of video title set menu language unit search pointers when the video title set menu language code does not equal to the language code of the player.

### Claim 3

An apparatus for reproducing information from a non-transitory computer readable information storage medium, including
video manager information, and
video title set information,
the video title set information comprising video title set menu language unit search pointers and video title set menu language units grouped for each language,
one of the video title set menu language unit search pointers comprising a video title set menu language code,
the video title set information comprising a video title set menu program chain information unit table information, and
the video title set menu program chain information unit table information comprising an end address of video title set menu program chain information unit table,
the apparatus comprising:
a processor configured to acquire one of the video title set menu language units corresponding to the video title set menu language code when the video title set menu language code equals to a language code of a player, and to acquire a video title set menu language unit search pointer which differs from the one of video title set menu language unit search pointers when the video title set menu language code does not equal to the language code of the player.
