ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an optical disk for storing digital data of multimedia data including audio information and moving image information that are associated with each other, as well as an apparatus and a method for reproducing the same.
2. Description of the Related Art
Conventionally, CDs (compact disks) and LDs (laser disks) are known as optical disks for storing and reproducing audio information and/or moving image information.
A CD is an optical disk having a diameter of 12 cm. A CD carries audio information stored thereon which has been quantized by using a linear PCM method. CDs are widely prevalent as a storage medium for music-oriented applications.
An LD is an optical disk having a diameter of 30 cm. An LD carries moving image information stored thereon in the form of analog signals. LDs are widely prevalent as a storage medium for image-oriented applications such as movies.
In addition to such uses, applications which cannot be distinguished to be either simply music-oriented or image-oriented have emerged, e.g., operas and the recently-evolved music clips (i.e., music accompanied by images).
Herein, those uses which cannot be distinguished as either music-oriented or image-oriented will be referred to as being directed to “image-accompanied music”.
In the case of applications of image-accompanied music, each user may prefer a different mode of view/listening. Some users may think that the usual video reproduction is sufficient, while others may wish to only enjoy high quality sounds/voices without any images, and yet a number of users may wish to enjoy music in high quality sounds/voices while being able to enjoy interviews and the like along with images.
SUMMARY OF THE INVENTION
According to the present invention, there is provided an optical disk including: a data region; and a management region, wherein the data region stores: at least one audio object containing audio information; and at least one video object containing video information and audio information, and wherein the management region stores a plurality of first management information units for managing progress of reproduction of the at least one audio object and a plurality of second management information units for managing progress of reproduction of the at least one video object, each of the plurality of first management information units including audio reproduction attributes and first path information indicating a reproduction order of the at least one audio object, each of the plurality of second management information units including video reproduction attributes and second path information indicating a reproduction order of the at least one video object, and wherein the management region further stores a first connection table containing first connection information and second connection information, the first connection information indicating a relationship of connection between the plurality of first management information units and the plurality of second management information units, and the second connection information indicating a relationship of connection among the plurality of first management information units.
In one embodiment of the invention, the management region further stores a second connection table consisting of the second connection information indicating the relationship of connection among the plurality of first management information units.
In another aspect of the present invention, there is provided a reproduction apparatus for reproducing an optical disk, the optical disk including a data region and a management region, the data region storing: at least one audio object containing audio information; and at least one video object containing video information and audio information, wherein the management region stores a plurality of first management information units for managing progress of reproduction of the at least one audio object and a plurality of second management information units for managing progress of reproduction of the at least one video object, each of the plurality of first management information units including audio reproduction attributes and first path information indicating a reproduction order of the at least one audio object, each of the plurality of second management information units including video reproduction attributes and second path information indicating a reproduction order of the at least one video object, and wherein the management region further stores a first connection table containing first connection information and second connection information, the first connection information indicating a relationship of connection between the plurality of first management information units and the plurality of second management information units, and the second connection information indicating a relationship of connection among the plurality of first management information units, the reproduction apparatus including: a reading section for reading at least one of the plurality of first management information units from the management region; and a reproduction section for reproducing the audio information contained in the at least one audio object in accordance with the at least one first management information unit that has been read.
In another aspect of the present invention, there is provided a reproduction apparatus for reproducing an optical disk, the optical disk including a data region and a management region, the data region storing: at least one audio object containing audio information; and at least one video object containing video information and audio information, wherein the management region stores a plurality of first management information units for managing progress of reproduction of the at least one audio object and a plurality of second management information units for managing progress of reproduction of the at least one video object, each of the plurality of first management information units including audio reproduction attributes and first path information indicating a reproduction order of the at least one audio object, each of the plurality of second management information units including video reproduction attributes and second path information indicating a reproduction order of the at least one video object, and wherein the management region further stores a first connection table containing first connection information and second connection information, the first connection information indicating a relationship of connection between the plurality of first management information units and the plurality of second management information units, and the second connection information indicating a relationship of connection among the plurality of first management information units, the reproduction apparatus including: a reading section for reading at least one of the plurality of second management information units from the management region; and a reproduction section for reproducing the video information and audio information contained in the at least one video object in accordance with the at least one second management information unit that has been read.
In another aspect of the present invention, there is provided a reproduction apparatus for reproducing an optical disk, the optical disk including a data region and a management region, the data region storing: at least one audio object containing audio information; and at least one video object containing video information and audio information, wherein the management region stores a plurality of first management information units for managing progress of reproduction of the at least one audio object and a plurality of second management information units for managing progress of reproduction of the at least one video object, each of the plurality of first management information units including audio reproduction attributes and first path information indicating a reproduction order of the at least one audio object, each of the plurality of second management information units including video
