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. An optical disk comprising:

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

a management information region for storing a plurality of sequence information which indicates a reproduction order of video segments included in each video sequence and indicates positions on the optical disk of the video segments included in each video sequence, and sequence-link information which indicates which one of two or more video sequences follows each video sequence depending on a value of a reproduction apparatus'"'"'s register,

wherein at least one of the video segments includes control command information which enables the value of the reproduction apparatus'"'"'s register to be updateds wherein the control command information includes a register information indicating one of the reproduction apparatus registers, an immediate value information indicating a predetermined value, a condition information indicating a comparison expression of a value indicated by the immediate value information to a value of the register indicated by the register information, and a link information indicating video sequences to be reproduced when a comparison expression indicated by the current condition information is true.

2. An optical disk according to claim 1, wherein a comparison expression indicated by the condition information is at least one of “

equal,”

“

not equal,”

“

less than,”

“

greater than,”

“

less than or equal,” and

“

greater than or equal.”

3. A reproduction apparatus for reproducing an optical disk as claimed in claim 1, comprising:

a reading means capable of reading and reproducing the video segments, the sequence information, and the sequence-link information from the disk;

a memory for storing the sequence information, the sequence-link information and the control command information separated from a reproducing video segment;

a controller for controlling the reading means; and

an instruction receiving means which is allowed to receive an instruction for executing the control command information included in a reproducing video segment,

wherein the controller controls the reading means to read the sequence information and the sequence-link information from the optical disk, controls the reading means to read the video segments in accordance with the sequence information and the sequence-link information depending on a value of a reproduction apparatus register, and updates the value of the reproduction apparatus'"'"'s register in accordance with the control command information stored in the memory when the instruction receiving means receives an instruction executing the control command information.

4. A reproduction apparatus according to claim 3,

wherein, after the reproduction of one video sequence is finished, the controller selects one of the two or more video sequences indicated by the sequence-link information depending on a value of the reproduction apparatus'"'"'s register, and controls the reading means to read the video segments in accordance with the selected sequence information.

5. A method of reproducing an optical disk as claimed in claim 1, comprising the steps of:

reading the management information region;

storing sequence information and sequence-link information;

storing control command information in the reproduction apparatus register;

reading the video segments in accordance with the stored sequence information and sequence-link information depending on the control command information in the reproduction apparatus register;

updating the control command information in the reproduction apparatus register when a new video segment is read with new control command information; and

reproducing the video segments in accordance with the current status of the reproduction apparatus register.

6. A system for reproducing an optical disk as claimed in claim 3, wherein the system reproduces video data from the optical disk when operatively installed in the reproduction apparatus.
