[Prior Art] Optical storage media such as optical disks have been widely used to store various types of media such as audio, video, materials and images. In the development of optical disc technology, a large number of physical or logical disc formats have been produced and commercialized. For example, physical media has gone through CDs to DVDs, to Bh_ray discs, and to other new optical storage media in the future. As for the logical format of the disc, there are CD-Audio 'pictures CD, vCD, SVCD, DVD, etc. The content types of the media include content types of audio formats such as MPEG1, MPEG2, AC-3, and Mp3, and content types of video formats such as MpEG1, MpEG2, and G4 DIVX. Describe each of these formats has lengthy and detailed specifications. Producers of the player must provide support for each format or suffer from a decline in market lock sales. Therefore, any new type of (physical or logical) introduction is a process of consumption and danger of resources, including, for example, content providers, player producers, etc., in close cooperation with = participants. Further, consumers are attracted to buy a new generation of players for each newly adopted disc format, but this is not possible to support other disc formats that compete with them. In addition, the new format is not supported by all content providers. As a result, there has been a big (four) confusion among consumers and a significant increase in the conditions for adopting the new format.

SUMMARY OF THE INVENTION The invention provides a compact disc having a general logical format. The disc has a data structure defined as being independent of the content type (i.e., data type and media encoding scheme) and physical media. According to an embodiment of the present invention, a data storage medium is provided, which is accessed by a data processing system. The data storage medium includes a data structure stored in the media for describing different bedding contents stored therein. The data structure includes at least one in-house object containing the content of the material, an object definition file associated with the object for describing the object, and an index file including a table of contents having object reference content. The general logical format of the present invention can be easily adapted to any new content type without defining a complete new format. Still further, different types of content may be stored on the same disc, and the content may be related or irrelevant. Furthermore, since the general logical format is independent of physical media, it may be in any existing or It will be executed in future disc media (such as DVD, Blu_ray disc, etc.). The invention may be more completely understood by reference to the following description of the appended claims and the appended claims. [Embodiment] According to the present invention, a general logic format having a data structure is used.

This is achieved by making the application layer of the disc independent of the physical level of the disc. In addition, the content identification file, usually located in the CD-in area, is moved from the physical level to the application level. By this method, the different data types of the content and the different uses of the content can be independent of the physical format of the optical disc, and coexist and interact on the same optical disc. Thus, for example, the -CD_audio format can exist on the -disc media and vice versa. Further, existing financial schemes (e.g., DVD viewing) can be easily executed on any future optical disc media and other storage media such as hard disk and flash memory having random access capabilities. 1 shows a general-purpose logical format 10' on a disc application level according to an embodiment of the present invention. The optical disc may be a recordable optical disc or a released ROM disc. The general logical format 1() includes a plurality of content object files 12 containing various material types of different programming schemes, and a plurality of object definition files 13 associated with the content object files 12, storing expression files relating to expression definitions of the playback objects. 16, and an index file index file 2G used as a startup file includes a content table (T〇c) 22, which includes a video file 26, an audio file 32, a data file 36, etc. on the optical disk. The reference content of the different file types to which the content object file 12 is associated. In the example, the index file 2G uses a meta language such as XML (extensible, language-speaking. Moreover, each content object file 12 is associated by including internal names, content types, content descriptions, etc. Object definition

Each object definition file 13 is preferably written in a meu language (e. g., XML). The presentation file 16 includes a menu and a playlist and is written in a meta language such as SMIL (Synchronized Multimedia Synthesis Language) to control synchronization and timing. The SMIL file is capable of obtaining the overall XML information about the content object file 12 from the associated object definition file for displaying the content object on the television screen. Of course, these files do not have to be written in XML or SMIL. Other _ languages including user-defined _language can also be used for the same purpose. Figure 2 is a flow chart showing the operation of a player having a disc having a general logical format in accordance with an embodiment of the present invention. The player typically includes a microprocessor. When the disc is read (step 102), the player will determine if there is a suitable analysis program (such as an XML parser) on the player. If there is no suitable knife on the player, it will determine whether the analysis program can be obtained from the CD (step, (7) or the Internet (step 116). If the analysis program is not available, the player will not be able to use the user. If the disc is unrecognizable (step calls and refuses to play the disc), if the analysis program is available from the disc or the network, the analyzer will obtain the analysis program (step 126). Once the analysis program is acquired, the analysis will be used. The program analyzes the index file 20 (step 132) 'to 7.

If it is not the last one, the steps between step 136 and step 156 will be repeated. After all objects have been analyzed, the player will display the filtered TOC with playable content to the customer on the TV screen (step 162). The filtered TOC is different from the playlist of the presentation file, which includes the reference content of the content objects that are only playable on a particular player. The file system is not required in the present invention, but the file system may be included in the optical disc as the case may be. In this case, the file system and the index file are independent of each other, and the player can address the content object by the file name from the file system or the track number from the index file. Although the present invention has been described in connection with the specific embodiments thereof, it will be readily apparent to those skilled in the art that various alternatives, modifications and variations can be made in accordance with the above description.
