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 management area and a data area,

said data area being provided for recording data in such a manner that the data is managed by one or more sequences and at least one sequence is composed of one or more programs corresponding to one or more cells,

said management area including a sequence management table for managing program sequences by determining an order of playback of said cells, and including a program management table for managing said programs, wherein

said program management table is configured to store first text information expressed in characters, and

a specific area, which is different from a recording area of said program management table in said management area, is configured to store second text information,

said program management table is configured to further record search information which includes a search pointer number of the second text information,

said specific area is configured to further store a search pointer indicating a location of the second text information, the search pointer number of the program management table corresponding to the search pointer when searching for the second text information,

wherein a first portion of the first text information describes primary text using an ASCII character set, and a second portion of said first text information describes primary text using another character set defined by a character set code included in a management table of said management area.

2. A method for recording information on an information storage medium, comprising the steps of:

recording a management area; and

recording a data area,

wherein;

said data area being provided for recording data in such a manner that the data is managed by one or more sequences and at least one sequence is composed of one or more programs corresponding to one or more cells,

said management area including a sequence management table for managing program sequences by determining an order of playback of said cells, and including a program management table for managing said programs, wherein

first text information expressed in characters is recorded in said program management table,

second text information is recorded into a specific area which is different from a recording area of said program management table in said management area,

said program management table is configured to further record search information which includes a search pointer number of the second text information,

said specific area is configured to further store a search pointer indicating a location of the second text information, the search pointer number of the program management table corresponding to the search pointer when searching for the second text information,

wherein a first portion of the first text information describes primary text using an ASCII character set, and a second portion of said first text information describes primary text using another character set defined by a character set code included in a management table of said management area.

3. A system for recording information on an information storage medium, comprising the steps of:

recording a management area; and

recording a data area,

wherein;

said data area being provided for recording data in such a manner that the data is managed by one or more sequences and at least one sequence is composed of one or more programs corresponding to one or more cells,

said management area including a sequence management table for managing program sequences by determining an order of playback of said cells, and including a program management table for managing said programs, wherein

first text information expressed in characters is recorded in said program management table,

second text information is recorded into a specific area which is different from a recording area of said program management table in said management area,

said program management table is configured to further record search information which includes a search pointer number of the second text information,

said specific area is configured to further store a search pointer indicating a location of the second text information, the search pointer number of the program management table corresponding to the search pointer when searching for the second text information,

wherein a first portion of the first text information describes primary text using an ASCII character set, and a second portion of said first text information describes primary text using another character set defined by a character set code included in a management table of said management area.

4. A method for reading information on an information storage medium, comprising the steps of:

reading a management area; and

reading a data area,

wherein;

said data area being provided for storing data in such a manner that the data is managed by one or more sequences and at least one sequence is composed of one or more programs corresponding to one or more cells,

said management area including a sequence management table for managing program sequences by determining an order of playback of said cells, and including a program management table for managing said programs, wherein

first text information expressed in characters is recorded in said program management table,

second text information is recorded into a specific area which is different from a recording area of said program management table in said management area,

said program management table is configured to further record search information which includes a search pointer number of the second text information,

said specific area is configured to further store a search pointer indicating a location of the second text information, the search pointer number of the program management table corresponding to the search pointer when searching for the second text information,

wherein a first portion of the first text information describes primary text using an ASCII character set, and a second portion of said first text information describes primary text (using another character set defined by a character set code included in a management table of said management area.

5. A system for reading information on an information storage medium, comprising the steps of:

reading a management area; and

reading a data area,

wherein;

said data area being provided for storing data in such a manner that the data is managed by one or more sequences and at least one sequence is composed of one or more programs corresponding to one or more cells,

said management area including a sequence management table for managing program sequences by determining an order of playback of said cells, and including a program management table for managing said programs, wherein

first text information expressed in characters is recorded in said program management table,

second text information is recorded into a specific area which is different from a recording area of said program management table in said management area,

said program management table is configured to further record search information which includes a search pointer number of the second text information,

said specific area is configured to further store a search pointer indicating a location of the second text information, the search pointer number of the program management table corresponding to the search pointer when searching for the second text information,

wherein a first portion of the first text information describes primary text using an ASCII character set, and a second portion of said first text information describes primary text using another character set defined by a character set code included in a management table of said management area.
