Abstract

An optical disk includes an audio data storage area for storing audio data; a still picture data storage area for storing a plurality of pieces of still picture data; and a management area for storing reproduction control information for controlling reproduction of the audio data and the plurality of pieces of still picture data. The reproduction control information has flag information representing specified still picture data among the plurality of pieces of still picture data.

Claims

1. An optical disk, comprising:

an audio data storage area for storing a plurality of pieces of audio data for at least one audio program;

a still picture data storage area for storing a plurality of pieces of still picture data; and

a management area for storing reproduction control information which defines a reproduction order of the plurality of pieces of audio data and a display order of the plurality of pieces of still picture data to be displayed simultaneously with the reproduction of the plurality of pieces of audio data, the reproduction order of the plurality of pieces of audio data and the display order of the plurality of pieces of still picture data being defined separately by the reproduction control information,

wherein the reproduction control information has specified still picture information indicating specified still picture data to be independently displayed by a specified operation regardless of the display order of the plurality of pieces of still picture data.

2. An optical disk according to claim 1, wherein the specified still picture information represents that specified still picture data is not included in the plurality of pieces of still picture data.

3. A reproduction apparatus for reproducing information stored on the optical disk according to claim 1, the reproduction apparatus comprising:

a reading section for reading the plurality of pieces of audio data and the plurality of pieces of still picture data from the optical disk; and

a reproduction control section for controlling a display order of the plurality of pieces of still picture data to be displayed simultaneously with the reproduction of the plurality of pieces of audio data in accordance with the reproduction control information,

wherein the reproduction control section specifies the specified still picture data among the plurality of pieces of still picture data in accordance with the specified still picture information.

4. A reproduction apparatus according to claim 3, wherein the specified still picture information represents that specified still picture data is not included in the plurality of pieces of still picture data.

5. A reproduction method for reproducing information stored on the optical disk according to claim 1, the method comprising the steps of:

reading the plurality of pieces of audio data and the plurality of pieces of still picture data from the optical disk; and

controlling a display order of the plurality of pieces of still picture data to be displayed simultaneously with the reproduction of the plurality of pieces of audio data in accordance with the reproduction control information,

wherein the step of controlling includes the step of specifying the specified still picture data among the plurality of pieces of still picture data in accordance with the specified still picture information.

6. A reproduction method according to claim 5, wherein the specified still picture information represents that specified still picture data is not included in the plurality of pieces of still picture data.

7. A recording medium having recorded thereon a program for causing a reproduction apparatus to carry out a reproduction method for reproducing information stored on the optical disk according to claim 1, wherein the reproduction method includes the steps of:

reading the plurality of pieces of audio data and the plurality of pieces of still picture data from the optical disk; and

controlling a display order of the plurality of pieces of still picture data to be displayed simultaneously with the reproduction of the plurality of pieces of audio data in accordance with the reproduction control information,

wherein the step of controlling includes the step of specifying the specified still picture data among the plurality of pieces of still picture data in accordance with the information.

8. A recording medium according to claim 7, wherein the specified still picture information represents that specified still picture data is not included in the plurality of pieces of still picture data.
