Abstract

When moving pictures are recorded onto an optical disc, not only is text data recorded, but also video-recording start date and time, video-recording end date and time, and source name or channel number serving as primary text data are recorded in alphanumeric characters program by program or cell by cell, a program or a cell being used as a unit of video-recording. Other text data is recorded together with language code. Since the primary text data used to select video data is expressed in alphanumeric characters, a program or cell to be reproduced can be selected, regardless of language, and the text information in the same language as that of the apparatus can be searched for.

Claims

1. An information storage medium comprising:

a data area configured to store data relating to a plurality of sequences; and

a management area configured to store a play list search pointer table arranged to describe information for searching and accessing play lists, wherein,

said play list search pointer table comprises at least one play list search pointer,

said at least one play list search pointer comprises primary text information for searching for, or for identifying, one of said play lists,

said at least one play list search pointer comprises an item text search pointer number, wherein said item text search pointer number is information for searching for, or for identifying, one of said play lists, and

said management area is configured to store a text data manager including text data information comprising information of a number of item text search pointers.

2. A method for recording information on an information storage medium including a management area and a data area, comprising the steps of:

recording in said data area data relating to a plurality of sequences; and

recording in said management area a play list search pointer table arranged to describe information for searching and accessing play lists, wherein,

said play list search pointer table comprises at least one play list search pointer,

said at least one play list search pointer comprises primary text information for searching for, or for identifying, one of said play lists,

said at least one play list search pointer comprises an item text search pointer number, wherein said item text search pointer number is information for searching for, or for identifying, one of said play lists, and

said management area is configured to store a text data manager including text data information comprising information of a number of item text search pointers.

3. A system for recording information on an information storage medium including a management area and a data area, comprising:

a first recorder configured to record in said data area data relating to a plurality of sequences; and

a second recorder configured to record in said management area a play list search pointer table arranged to describe information for searching and accessing play list, wherein,

said play list search pointer table comprises at least one play list search pointer,

said at least one play list search pointer comprises primary text information for, searching for or for identifying, one of said play lists,

said at least one play list search pointer comprises an item text search pointer number, wherein said item text search pointer number is information for searching for, or for identifying, one of said play lists, and

said management area is configured to store a text data manager including text data information comprising information of a number of item text search pointers.

4. A method for reading information from an information storage medium including a management area and a data area, comprising the steps of:

reading from said management area a play list search pointer table arranged to describe information for searching and accessing play lists; and

reading from said data area data relating to a plurality of sequences, wherein,

said play list search pointer table comprises at least one play list search pointer,

said at least one play list search pointer comprises primary text information for, searching for or for identifying, one of said play lists,

said at least one play list search pointer comprises an item text search pointer number, wherein said item text search pointer number is information for searching for, or for identifying, one of said play lists, and

said management area comprises a text data manager including text data information comprising information of a number of item text search pointers.

5. A system for reading information from an information storage medium including a management area and a data area, comprising:

a first reader configured to read from said data area data relating to a plurality of sequences; and

a second reader configured to read from said management area a play list search pointer table arranged to describe information for searching and accessing play list, wherein,

said play list search pointer table comprises at least one play list search pointer,

said at least one play list search pointer comprises primary text information for, searching for or for identifying, one of said play lists,

said at least one play list search pointer comprises an item text search pointer number, wherein said item text search pointer number is information for searching for, or for identifying, one of said play lists, and

said management area comprises a text data manager including text data information comprising information of a number of item text search pointers.
