Abstract
If, in a recording medium on which a plurality of programs are collected in a plurality of groups and supervised in this grouped state, a command for editing, such as dividing/linking/erasing the predetermined programs or groups, recorded on the recording medium, the management data is to be edited to perform the editing. The present invention contemplates to provide a solution to meet this request by a recording medium, an editing method and an editing apparatus.
Claims31
A recording medium in which a plurality of programs are collected into a plurality of groups and are managed and recorded in this form, comprising:
- a program recording area in which said programs are recorded;
- a first management data recording area in which the first management data for supervising the program names of said plural programs is recorded;
- and
- a second management data recording area in which the names of the programs collected in said plural groups and the names of said groups are correlated and are recorded as the second management data along with the separating information for separating the program names and the group names.
An editing apparatus for editing a program recorded on a recording medium including a program area for recording a plurality of programs for recording a plurality of programs, and a management area, having recorded therein the first management data for managing the program names for respective programs recorded in said program area, and the second management data, made up of the range information of program numbers making up each of a plurality of groups into which the plural programs recorded in said program area are collected, special codes partitioning said groups from one another, and group names, comprising:
- operating means for commanding changes in the sequence of predetermined ones of said plural groups;
- and
- editing means which, in case changes in the sequence of predetermined ones of said plural groups are commanded by said operating means, edits the correlation of said range information of program numbers making up each of a plurality of groups in said second management data and said group names to cause block movement of said predetermined groups.

- operating means for commanding division of a predetermined program of predetermined ones of said plural groups;
- and
- editing means which, in case division of a predetermined program of predetermined ones of said plural groups is commanded by said operating means, edits the correlation of said range information of program numbers making up each of a plurality of groups in said second management data and said group names.

- operating means for commanding linking of two of the programs making up a predetermined group of said plural groups;
- and
- editing means-which, in case linking of two of the programs making up a predetermined group of said plural groups is commanded by said operating means, edits the correlation of said range information of program numbers making up each of a plurality of groups in said second management data and said group names.
An editing apparatus for editing a program recorded on a recording medium including a program area for recording a plurality of programs for recording a plurality of programs, and a management area, having recorded therein the first management data for managing the program names for respective programs recorded in said program area, and the second management data, made up of the range information of program numbers making up each of a plurality of groups into which the plural programs recorded in said program area are collected, special codes partitioning said groups from one another, and group names, comprising:
- operating means for commanding division of a predetermined group of said plural groups into two;
- and
- editing means which, in case division of said predetermined group is commanded by said operating means, edits the correlation of said range information of program numbers making up each of a plurality of groups in said second management data and said group names.
An editing apparatus for editing a program recorded on a recording medium including a program area for recording a plurality of programs for recording a plurality of programs, and a management area, having recorded therein the first management data for managing the program names for respective programs recorded in said program area, and the second management data, made up of the range information of program numbers making up each of a plurality of groups into which the plural programs recorded in said program area are collected, special codes partitioning said groups from one another, and group names, comprising:
- operating means for commanding linking of predetermined ones of said plural groups;
- and
- editing means which, in case linking of predetermined ones of said plural groups is commanded by said operating means, edits the correlation of said range information of program numbers making up each of a plurality of groups in said second management data and said group names to cause block movement of said predetermined groups.
An editing apparatus for editing a program recorded on a recording medium including a program area for recording a plurality of programs for recording a plurality of programs, and a management area, having recorded therein the first management data for managing the program names for respective programs recorded in said program area, and the second management data, made up of the range information of program numbers making up each of a plurality of groups into which the plural programs recorded in said program area are collected, special codes partitioning said groups from one another, and group names, comprising:
- operating means for commanding block erasure of predetermined ones of said plural groups;
- and
- editing means which, in case block erasure of predetermined ones of said plural groups is commanded by said operating means, edits the correlation of said range information of program numbers making up each of a plurality of groups in said second management data and said group.
