Method and device for editing program search information

The present invention relates to the field of optical storage, and more particularly to a method and apparatus for editing program retrieval information.

The development of optical storage technology has made optical discs and their broadcast products a popular entertainment product. Personalization and networking have become two important directions in the development of optical storage. For example, in the Blu-ray Disc format, the introduced Java application allows users to design their own operating interface that suits their preferences and is more linkable than before. The enhanced DVD disc format of the Internet, the Blu-ray Disc format has a stronger network link function.

The implementation of the disc playback function is mostly based on the ability of the disc playback device to retrieve the disc program. For example, the reason why users can selectively play different programs and different chapters is because the description information of different programs and different chapters has been edited and managed as disc retrieval information, such as editing into programs or Thumbnail Picture of the chapter, etc. for retrieval. Therefore, in order to realize the enhanced disc playing function, it is necessary to perform an enhanced search on the disc program.

Enhanced search allows the user to retrieve all scenes including the particular actor or specific location, etc., using a particular actor, place, or other constituent element in the scene as a search key. Compared with the original search for chapters or sections, enhanced search has more rich search keywords and a lower search level, so it can also support more powerful playback functions, such as interactive performance of CD playback.

In traditional optical disc retrieval, the retrieval information is defined in the file system (such as a menu file) or in a playlist file (Playlist). Through the menu file or playlist file, the keyword information (such as program name, chapter, section, etc.) is used as an indicator to guide the disc playback control file to access the description information (such as time, address, etc.) of the corresponding retrieved object. Other files can be used to retrieve CD programs.

For enhanced retrieval, because the retrieval level is low and accurate to each scene, the amount of information is relatively large regardless of whether the keyword information or the description information of each scene is retrieved. A large amount of information for retrieval will make the traditionally cumbersome search process more cumbersome, and if it is placed in the file system as well as the menu file, the management of the file system will also cause certain difficulties.

Therefore, there is a need to provide a method and apparatus for editing program retrieval information to enable enhanced retrieval of optical disc programs in a simple process.

The technical problem to be solved by the present invention is to provide a method and apparatus for editing program retrieval information to overcome the problems in the prior art.

According to an embodiment of the present invention, a method for editing program search information is provided, the method comprising the steps of: obtaining description information of a scene of the program, the description information including a description of a scene element; generating according to the description information a scene retrieval information unit; and, according to the scene retrieval information unit, a search information file for searching for the program.

In the above method, the scene search information unit may include a title of the search information unit, a description of the corresponding scene, a description of an element in the corresponding scene, and the like, wherein the search information file may be a search information list.

According to an embodiment of the present invention, there is provided an apparatus for editing program search information, the apparatus comprising: an obtaining means for acquiring description information of a scene of the program, the description information including a description of a scene element; a generating device, configured to generate a scene search information unit according to the description information; and an editing device, configured to edit a search information file according to the scene search information unit for searching the program.

The other objects and attainments of the present invention will be apparent from the description and appended claims.

The concept of the present invention is as follows: in order to implement a simple and enhanced search, when a CD program is stored on a disc or when an optical disc program is edited offline, a search information unit is generated according to the scene description information of the disc program, including the scene. The description and description of the scene elements therein are then edited in a search information archive (such as a news manifest file) for enhanced disc retrieval. With such a scheme, the retrieval of keyword information and the description information of the scene and the description information of the scene elements are unified and used directly as the retrieved information for retrieval, without the need to search for a search file such as a traditional menu search. The index information is used to search, which simplifies the process of enhanced search.

1 is a flow chart of a method of editing program retrieval information in accordance with one aspect of the present invention. This example illustrates the online burning of a disc program. When the optical disc is burned, the optical disc burning device first receives the optical disc program to be burned from the network or other storage medium (step S110). Of course, the program to be burned can also be stored in the storage unit of the optical disc burning device.

Then, the description information of a scene in the CD program material and the scene elements therein is acquired (step S120). A CD program includes many scenes. Correspondingly, the CD program data also includes a plurality of scene materials, and each scene material includes data for the entire scene, and information for each element therein. Based on this information, information about the description of the entire scene and descriptions of each of the scene elements can be obtained, such as time description information, address description information, name information of a specific scene or a specific element, and other scene or scene elements. Related information, status information of scene elements, type information of scene elements, quantity information, and the like. Such description information enables the disc playback device to retrieve scenes and scene elements by various search keywords in future disc playback.

Then, based on the acquired description information, a search information unit is generated (step S130). The search information unit generated includes the name of the search information unit, the name of the corresponding scene, the description information of the corresponding scene (such as time, address, etc.), and the description information of the corresponding elements in the scene (eg, The name of the actor, the costume, etc., and the description of the scene location, etc.).

Then, the generated search information unit is edited in a search information file (such as a news list) (step S140). The search information file may be a separate search information list file, which includes each search information unit for retrieval, or may be a part or a piece included in a playlist file for retrieval.

Finally, the program and the search information file are stored on the optical disc (step S150). This method of establishing a search information file can be used in editing a CD-ROM or in a rewritable disc. For rewritable discs, offline editing of the disc program can also be performed after the disc program has been stored on the disc.

According to the above method, the description information corresponding to a scene and its elements is included in a corresponding retrieval data unit, and is edited in a disc retrieval information file for enhanced retrieval. When playing a disc, the user can retrieve the keyword information by using a specific scene element (such as the name of the actor), and directly search the information file by the disc to realize enhanced retrieval of the disc program.

2 is a block diagram of an apparatus 200 for editing program retrieval information in accordance with one aspect of the present invention. The device 200 includes an obtaining device 210 for obtaining description information of a scene of a section, including a description of a scene element. For example, a scene is a scene list number of the program or chapter, a name of a scene element (person, place, etc.) included in the scene, a description of the state of each scene element, and the like.

The device 200 also includes a generating device 220, configured to generate a scene search information unit according to the description information, including information based on the scene element as a search keyword. Corresponding to a scene, a search information unit is generated, and the information unit includes a name of the search information unit, a name of the corresponding scene, and description information (such as time, address, data amount, etc.) of the corresponding scene, and corresponding scenes. Descriptive information about the elements in the middle (such as the name of the actor, clothing, etc., and description of the scene location, etc.).

The device 200 also includes an editing device 230 for editing a search information file according to the scene retrieval information unit for searching the optical disc program. The search information units corresponding to each scene are edited together to form a search information file, and the scene search information unit can also be added to an existing search information file, that is, the search information file can be open and updateable. A plurality of scene retrieval units may be included in the retrieval information list file.

The device 200 can be included in a compact disc burning device. The optical disc burning device including the device 200 may further include a disc program receiving device for receiving the optical disc program to be burned on the optical disc.

The present invention will now be described by way of an example in which a disc program of a rewritable Blu-ray Disc (Blu-ray RE) can be enhancedly searched.
