Abstract

A multimedia optical disk is provided. The multimedia optical disk includes a data area for storing objects which include moving picture data and at least one of audio data and sub-picture data. The multimedia optical disk also includes an index area for storing reproduction orders of the objects. Route information in the index area includes a sequence of addresses of objects whose alignment represents a reproduction order. Chain control information in the index area corresponds to the route information. The chain control information, being effective in reproducing objects specified by the alignment of the sequence of addresses (objects specified by the alignment of the sequence of addresses are called a chain), instructs the reproduction apparatus to have a navigation control of the chain. A piece of moving picture data having a certain time period is reproduced at the same timing as a piece of audio data and a piece of sub-picture data. A piece of sub-control information, being effective in reproducing moving picture data, sub-picture data, and audio data stored in a small unit instructs the reproduction apparatus to have a navigation control of the data stored in the same small unit.

Claims

1. A machine readable recording medium comprising:

a data region storing a plurality of video sequences composed from a plurality of video segments, and

a management information region storing sequence information which indicates a reproduction order of video segments included in each video sequence and indicates positions of the video segments included in each video sequence, and sequence-link information indicating which video sequence follows each video sequence,

wherein the management information region includes a first command control information for at least one of the video sequences that is to be executed before the reproduction of the video segments in the video sequence and a second command control information, for at least one of the video sequences that is to be executed after the reproduction of the video segments in the video sequence.

2. The machine readable recording medium of claim 1, wherein the first command control information provides at least one set register value to control the manner in which the video segments are reproduced.

3. The machine readable recording medium of claim 2, wherein the set register value indicates whether a video segment has been previously reproduced.

4. The machine readable recording medium of claim 1, wherein the first command control information includes a command to generate a random integer for initialization of a register value.

5. The machine readable recording medium of claim 1, wherein the second command control information provides a set register value in response to the manner in which a video segment was reproduced.

6. The machine readable recording medium of claim 5, wherein the first command control information provides at least one set register value to control the manner in which the video segments are reproduced.

7. The machine readable recording medium of claim 6, wherein the set register value indicates whether a video segment has been previously reproduced.

8. The machine readable recording medium of claim 5, wherein the first command control information includes a command to generate a random integer for initialization of a register value.

9. The machine readable recording medium of claim 1, wherein the second command control information provides a branch command to another video sequence after reproduction of the video segments.

10. A machine readable recording medium comprising:

a data region storing a plurality of video sequences composed from a plurality of video segments; and

a management information region storing sequence information which indicates a reproduction order of video segments included in each video sequence and indicates positions of the video segments included in each video sequence, and sequence link information indicating which video sequence follows each video sequence,

wherein the management information region includes a first command control information, for at least one of the video sequences, that is to be executed before the reproduction of the video segments in the video sequence and a second command control information, for at least one of the video sequences, that is to be executed after the reproduction of the video segments in the video sequence, the first command control information includes values that are to be stored in a manner to enable the values to be overwritten by a user during the reproduction of the video segments, whereby an interactive feature of varying video images as a result of user interaction is provided.

11. The machine readable recording medium of claim 10, wherein the second command control information provides at least one set register values that can be overwritten in response to user interaction during the reproduction of the video segments.

12. A reproduction apparatus for reproducing data from a data region storing a plurality of video sequences composed from a plurality of video segments, and a management information region storing sequence information which indicates a reproduction order of video segments included in each video sequence and indicates positions of the video segments included in each video sequence, and sequence-link information indicating which video sequence follows each video sequence,

whereby the management information region includes a first command control information for at least one of the video sequences that is to be executed before the reproduction of the video segments in the video sequence and a second command control information, for at least one of the video sequences that is to be executed after the reproduction of the video segments in the video sequence, comprising:

a reading unit for reading and reproducing the video segments, the sequence information, the sequence-link information, the first command control information, and the second command control information;

a memory for storing the information that is read;

a receiving unit for receiving a user'"'"'s operation to provide an interactive choice from the user; and

a controller for executing the first command control information before the reproduction of the video segments in the video sequence, for reproducing the video sequence, and for executing the second command control information after the reproduction of the video segments in the video segments.

13. The reproduction apparatus of claim 12 further including a remote controller for inputting a user operation to the receiving unit.

14. A method of reproducing data from a plurality of video segments, sequence information which indicates a reproduction order of video segments included in each video sequence and indicates positions of the video segments included in each video sequence, sequence-link information indicating which video sequence follows each video sequence, a first command control information, for at least one of the video sequences, that is to be executed before the reproduction of the video segments in the video sequence and a second command control information, for at least one of the video sequences, that is to be executed after the reproduction of the video segments in the video sequence, comprising the steps of:

reading the data;

storing the data;

executing the first command control information to establish at least a first parameter prior to a subsequent reproduction of the video segments;

reproducing the video segments; and

executing the second command control information to establish at least a second parameter after the reproduction of the video segments.

15. The method of reproducing data of claim 14 further including the steps of:

receiving a user input command; and

changing one of the first and second parameters in response to the user input command, whereby the reproduction of the video segments may be altered by the first parameter and the reproduction of subsequent video segments in another video sequence may be set by the second parameter.
