Abstract
An information recording apparatus of this invention includes a MAIN MPU for generating manager information representing the correspondence between a compressed content and a program for expanding the content, and a disc drive section for recording the content, program, and manager information on an information recording medium.
Claims21
An information recording apparatus comprising:
- a first input means for inputting a compressed content;
- a second input means for inputting a program for expanding the content;
- generation means for generating manager information representing a correspondence between the compressed content and the program;
- and
- recording means for recording the content, program, and manager information on an information recording medium,
- wherein the manager information contains
- information representing a compressing scheme of the content and presence/absence of a program corresponding to the compression scheme,
- information representing a recording start position of the program for expanding the content, and
- information representing a size of the program for expanding the content.
6 more elements
An information recording method comprising:
- inputting a compressed content and a program for expanding the content;
- generating manager information representing a correspondence between the compressed content and the program;
- and
- recording the content, program, and manager information on an information recording medium,
- wherein the manager information contains
- information representing a compression scheme of the content and presence/absence of a program corresponding to the compression scheme,
- information representing a recording start position of the program for expanding the content, and
- information representing a size of the program for expanding the content.
5 more elements
An information reproduction apparatus comprising:
- read means for reading out, from an information recording medium, manager information representing a correspondence between a compressed content and a program for expanding the content and reading out the content and program on the basis of the manager information;
- and
- reproduction means for expanding and reproducing the content on the basis of the program read by said read means,
- wherein the manager information contains
- information representing a compression scheme of the content and presence/absence of a program corresponding to the compression scheme,
- information representing a recording start position of the program for expanding the content, and
- information representing a size of the program for expanding the content.
4 more elements
An information reproduction method comprising:
- reading out, from an information recording medium, manager information representing a correspondence between a compressed content and a program for expanding the content;
- reading out the content and program on the basis of the manager information;
- and
- expanding and reproducing the content on the basis of the readout program,
- wherein the manager information contains
- information representing a compression scheme of the content and presence/absence of a program corresponding to the compression scheme,
- information representing a recording start position of the program for expanding the content, and
- information representing a size of the program for expanding the content.
5 more elements
An computer-readable medium encoded with a computer program comprising:
- a content recording area in which a compressed content is recorded;
- a program recording area in which a plurality of programs corresponding to a plurality of compression schemes are recorded together, each of the programs expanding the compressed content;
- and
- a manager information recording area in which the manager information representing a correspondence between the compressed content and the program for expanding the content is recorded,
- wherein the manager information contains
- information representing a compression scheme of the content and presence/absence of a program corresponding to the compression scheme,
- information representing a recording start position of the program for expanding the content, and
- information representing a size of the program for expanding the content.
