Record medium with managed digest portions of programs, reproducing apparatus thereof, and reproducing method thereof

A reproducing apparatus for reproducing data from a record medium having a program region in which at least one program is recorded and a management region in which management information is recorded, the management information managing the number of programs recorded in the program region, the record positions of the programs, and the position of digest information of at least one program recorded in the program region, the reproducing apparatus comprising:

• reproducing means for reproducing a management information and a program recorded on a record medium;
• extracting means for extracting a position information of a digest information of the program from the management information;
• operating means for designating a digest reproduction;
• and
• controlling means for controlling the reproducing means so as to successively reproduce programs recorded in the program region corresponding to the position information extracted from the extracting means when the operating means designates the digest reproduction.

A reproducing method for reproducing data from a record medium having a program region in which at least one program is recorded and a management region in which management information is recorded, the management information managing the number of programs recorded in the program region, the record positions of the programs, and the position of digest information of at least one program recorded in the program region, the reproducing method comprising the steps of:

• (a) reproducing a management information and a program recorded on a record medium;
• (b) extracting an identifier from the management information reproduced at step (a) and determining whether or not a digest information is managed;
• (c) if the digest information is managed as the determined result at step (b), extracting the position from the management information and storing the extracted position;
• (d) determining whether or not a digest reproduction has been reproduced;
• and
• (e) if the digest reproduction has been designated at step (d), successively reproducing programs recorded in the program region corresponding to the position information being stored.

A method of reproducing data from a record medium having a program region in which at least one program is recorded and a management region in which management information is recorded, the management information managing the number of programs recorded in the program region, the record positions of the programs, and the position of digest information of at least one program recorded in the program region, the method comprising the steps of:

• reproducing a management information and a program recorded on a record medium;
• extracting a position information of a digest information of the program from the management information;
• designating a digest reproduction;
• and
• successively producing programs recorded in the program region corresponding to the position information extracted from the extracting means when the designating means designates the digest reproduction.
