Benefits of technology

[0012] Further, another object of this invention is to make it possible to reproduce data halfway when data to be dealt with is linear audio data, and make it possible to easily detect the environment in which data can be used when data to be dealt with is computer data.

Problems solved by technology

However, in this case, the user can add but two kinds of data classification which, and the expandability is limited.
As a result, it becomes impossible to freely deal with various classifications of data items and cope with the condition in the multimedia age.
Further, if a maximum data length is set for packets of data other than MPEG audio data and if the data length of the packet cannot be divided by the number of data items of a completed frame data block, the preceding data block will enter the packet and there occurs a possibility that the starting address of the frame data block cannot be determined, and when data is reproduced halfway, it may be impossible to reproduce the data.

Embodiment Construction

[0076] Hereinafter, referring to the accompanying drawings, an optical disk reproducing apparatus according to an embodiment of the present invention will be explained.

[0077]FIG. 1 is a block diagram of an optical disk reproducing apparatus that reproduces the data from an optical disk associated with an embodiment of the present invention. FIG. 2 is a block diagram of the disk drive section that drives the optical disk shown in FIG. 1. FIG. 3 shows the structure of the optical disk shown in FIGS. 1 and 2.

[0078] As shown in FIG. 1, the optical disk reproducing apparatus comprises a key / display section 4, a monitor section 6, and a speaker section 8. When the user operates the key / display section 4, this causes the recorded data to be reproduced from an optical disk 10. The recorded data contains video data; sub-picture data, and audio data, which are converted into video signals and audio signals. The monitor section 6 displays images according to the video signals and the speaker...

Abstract

Data is recorded in a data area of a disk in a hierarchical structure of program chains, programs, cells and packs, each pack is constructed by a pack header for identifying the pack and a packet having a data stream recorded therein, the packet has a packet header having a stream ID indicating at least a private stream and a sub-stream ID indicating the classification of the private stream described therein, and the classification indicates packet data of Dolby AC3 audio data, packet data of linear audio data, packet data of sub-picture data, or packet data of computer data.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a recording medium such as an optical disk for recording data items of different classifications used for different purposes, for example, compressed moving picture data and audio data, a recording apparatus for recording data into the recording medium, a recording method for recording data into the recording medium, a reproducing apparatus for reproducing data from the recording medium, and a reproducing method for reproducing data from the recording medium. [0003] 2. Description of the Related Art [0004] Conventionally, as a system for compressing (coding) digital moving picture image data and audio data, an MPEG (Moving Picture Experts Group) system is internationally standardized. The MPEG compression system is a system for subjecting digital moving picture image data and audio data to the variable-length compression. [0005] Further, the system format system corresponding to the MPEG co...
