Description

Information storage medium for storing metadata, system and method for processing metadata

technical field

The present invention relates to metadata, and more particularly, to an information storage medium for storing metadata supporting multiple languages, a system and a method for processing the metadata.

Background technique

An information recording medium such as a digital versatile disc (DVD) may store content such as audio/video (AV) data and information on the content such as metadata. Examples of metadata include information on the title of a movie stored on a disc, information on the production date of the movie, information on actors and actresses who starred in the movie, and information on the director of the movie. Accordingly, the user may search for content with a desired title or search for content of a specific actor or actress as a main character with reference to metadata.

If metadata is provided in multiple languages, people from different countries can easily search for content with reference to different versions of metadata written in multiple languages. In other words, a user can search and browse metadata by using a language he or she understands. In addition, metadata written in languages other than those stored on the information recording medium may also be downloaded over a network, or may be copied from another storage, for user's convenience.

FIG. 1 is a block diagram illustrating an exemplary format of subtitle data 100 . With reference to Fig. 1, subtitle data 100 comprises: text data 110, will be displayed as subtitle; Synchronization information 120, specify when to display text data 110 synchronously with AV stream; Display area information 130, specify where to display text data 110; and display style information 140 specifying that the text data 110 will be displayed in a specific display style. The display region information 130 may be expressed as region(1, t, w, h) to indicate that the text data 110 is to be displayed in a region of width "w" and height "h" at point (1, t). The display style information 140 includes font information, output direction information, and line interval information on the text data 110 to be displayed in the same area.

FIG. 2 is a block diagram of an exemplary reproducing apparatus 200 for reproducing subtitle data in synchronization with an AV stream. Referring to FIG. 2 , the reproducing device 200 reads the subtitle data 100 shown in FIG. 1 from the information storage medium 210, downloads the subtitle data 100 from the server 220 through a network such as the Internet 230, and reproduces the subtitle data 100 synchronously with the AV stream 240. . The subtitle data 100 and the AV stream 240 may be separately stored on the information storage medium in different units. In other words, subtitle data 100 placed on an image generated by decoding the AV stream may be recorded on the information storage medium separately from the AV stream. In order to provide users with subtitle data 100 or multiple types of subtitle data 100 in multiple languages, the reproducing device 200 can also download the subtitle data 100 from the server 220 through a network such as the Internet 230, and can share with the subtitle data obtained from the information storage medium 210. Downloaded subtitle data is reproduced in the same manner as the data.

As described above, for example, as shown in FIG. 2 , subtitle data 100 read from an information storage medium or downloaded from a server 220 through the Internet 230 may be provided to a user. As with subtitle data, for example, as shown in FIG. 2, metadata can be obtained from an information storage medium or from a remote server via the Internet, and provided to users. In other words, metadata written in multiple languages may be recorded in an information storage medium, and metadata written in some other languages may be stored in a remote server via the Internet, so that it can be read from the information storage medium and via the Internet The metadata is downloaded from a server. However, in the conventional method representing downloading metadata over a network, a large amount of storage capacity may be wasted for storing metadata. Also, in the study of metadata, two words written in different languages may be determined to mean different things even though they have the same meaning.

Contents of the invention

technical problem

Therefore, even if memory resources are limited in a reproduction device and/or an information storage medium, it is necessary to provide accessible and updateable metadata written in a plurality of different languages so that users can easily search for content in a desired language that can be understood. There is also a need to improve metadata search techniques so that multiple words with the same meaning but written in different languages are not mistaken for different metadata.

Technical solutions

Aspects of the present invention advantageously provide an information storage medium for storing metadata supporting multiple languages and a method of processing the metadata, the information storage medium enabling a user to use the Metadata in media or metadata in different languages downloaded from other storage media, metadata in a desired language is browsed through a reproduction device and desired content is searched with reference to the metadata.

Beneficial effect

As described in the present invention, only one language list that can be provided by a reproducing apparatus is provided, and metadata written in a desired language can be downloaded from a server storing metadata written in a desired language with reference to the stored language list. Thus, metadata in more than one language can be provided to the user even for rendering devices with limited memory resources. This is achieved by simply downloading metadata from the server. Also, in metadata search, it is now possible to easily determine whether a plurality of metadata written in different languages means the same as another metadata by using a plurality of parameter sets under descriptors written in different languages.

In addition to the exemplary embodiments and aspects described above, other aspects and embodiments of the present invention will become apparent by reference to the accompanying drawings and by study of the following description.

Detailed ways

The present invention is applicable for use with all types of memory or computer-readable media, recording and/or reproducing devices, and computer systems implementing the methods described according to various embodiments of the present invention.

According to various aspects of the present invention, metadata in multiple languages can be provided through three methods. In the first method, various versions of metadata written in a plurality of languages other than the predetermined language of the metadata stored on the disc can be provided by using a manifest file including Language code information for the language in which the metadata for each version is written, and a Uniform Resource Locator (URL) specifying the location of one or more remote servers over a network that store the metadata for the various versions in different languages. As a result, metadata can be provided in multiple languages by using a manifest file including language code information, disc identification information for identifying a disc, and URL information with ease using a reproducing apparatus having limited memory resources.

In the second approach, metadata can be classified into language-dependent and language-independent parts. Thereafter, representative metadata may be subsequently formed using common metadata including an identifier (ID) of the language in which the language-independent parts of the metadata, the language-dependent parts, are written. As a result, metadata in multiple languages can be provided conveniently with limited memory resources.

In a third approach, metadata in multiple languages can be provided by using multiple parameter sets written in each descriptor. Each descriptor may include multiple parameter sets written in different languages (eg, English, Chinese, and Korean). As a result, specific words written in different languages that have the same meaning can be clearly and easily identified during metadata searches.

Therefore, according to aspects of the present invention, metadata can be easily updated even if an information recording medium such as a disc is released on the market. In other words, the addresses of multiple remote servers can be stored in a manifest file stored on disk (the first method) or in a common metadata file (the second method), where the A remote server downloads multiple versions of metadata in addition to the metadata version stored on disk. Therefore, the user can determine which remote server stores the metadata of the desired version, and can download the metadata of the desired version based on the determined result. In the third method, metadata can be updated in units of descriptors.

The first to third methods mentioned above will now be described in detail with reference to FIGS. 3 to 8 .

FIG. 3 is a diagram for explaining a method of providing metadata in multiple languages using a manifest file according to an exemplary embodiment of the present invention. Referring to FIG. 3 , multiple versions of metadata to be written in multiple languages are stored as separate metadata files, for example, an English metadata file 310 , a Japanese metadata file 320 , and a Korean metadata file 330 . Server location information is stored in each of the respective metadata files 310, 320, and 330 regarding a plurality of servers from which some other corresponding language metadata is downloaded. The location information of the server may be Uniform Resource Locator (URL) information. The English metadata file 310, the Japanese metadata file 320, and the Korean metadata file 330 may have different URL information. Available languages are identified by the names of the respective language metadata files (eg, English metadata file 310, Japanese metadata file 320, and Korean metadata file 330). The names used may include language identifiers according to the ISO639-2 standard.

Manifest file 340 may include: disc ID information 342, used to identify information storage media such as discs; language code information 344, used to specify language codes corresponding to language metadata files 310, 320 and 330, for example, English, Japanese and Korean ; Server location information 346 for identifying one or more remote servers from which metadata in some other language may be downloaded over the network.

Thus, referring to the manifest file 340, the user can check the list of languages supported by the disc and select one of the listed languages, or as shown in FIG. 4, additionally download a version of the metadata written in the desired language from the server 420. For example, if a user wishes to download the French version of the metadata, the user may check the manifest file 340 that stores the URL of the server 420 where the French version of the metadata is stored. Thereafter, the user accesses the server 420 by clicking on the URL of the server 420, and then downloads the metadata of the French version from the server 420. The manifest file 340 may be formed to have information on each language of a size of 512 bytes, for example, the manifest file 340 includes disc ID information 342 , language code information 344 and server location information 346 as shown in FIG. 3 . Therefore, assuming that 32 versions of metadata written in 32 languages can be provided through a digital versatile disc (DVD), the manifest file 340 can be formed to have a size of approximately 16K bytes (=32×512 bytes), in which case Below, the maximum storage capacity required to store 1000 manifest files is about 16M bytes. In other words, the information storage medium only needs to store server location information for a small number of metadata files for some languages and desired metadata files for other languages, so as to minimize memory resources used.

Therefore, even if the reproducing device does not have sufficient memory resources, it is possible to provide multiple versions of metadata written in multiple languages with reference to the manifest file 340 without storing the multiple versions of metadata therein. The manifest file 340 includes disc ID information identifying a disc, language code information on the plurality of languages available, and server location information specifying where metadata of the plurality of versions can be found. Since multiple versions of metadata written in different languages can be stored on one or more remote servers or other storage media and easily accessed by users, it is convenient to make distributions in information storage media for metadata memory resources are minimized.

Turning now to FIG. 4 , FIG. 4 shows a flowchart of a method for displaying content using a manifest file according to an embodiment of the present invention. Referring to FIG. 4, when an information storage medium such as a disc 410 is inserted into the reproducing apparatus 400, the manifest file 340 of the disc 410 is stored in a memory of the reproducing apparatus 400 at operation S410. As shown in FIG. 3 , the manifest file 340 includes disc ID information 342 for identifying a disc, language code information 344 for specifying a language supported by the disc, and server location information 346 for identifying at least one server 420 . In operation S420, a URL of a server 420 storing a desired version of metadata written in a desired language is accessed with reference to the server location information 346 included in the manifest file 340. Referring to FIG. In operation S430, metadata of a desired version is downloaded from the server 420 accessed in operation S420, and the downloaded content is displayed on the display unit 430.

5 is a diagram explaining a method of naming each of a plurality of metadata files written in different languages (for example, an English metadata file 310, a Japanese metadata file 320, and a Korean metadata file 330 as shown in FIG. 3 ). diagram. Referring to FIG. 5, if the metadata file is named to specify (1) the disc ID to which the metadata file belongs and (2) the language code supported by the disc, the disc ID information and language code information can be easily obtained from the name of the metadata file. For example, as shown in FIG. 5, the metadata file is named "disc_id.kor.meta", which is used to identify not only the disc ID but also the Korean language in which the metadata is written. Similarly, the metadata file is also named "disc_id_eng.meta", which is used not only for identifying the disc ID but also for English in which the metadata is written. Likewise, the metadata file is also named "disc_id.jpn.meta" which is used to identify not only the disc ID but also the Japanese language in which the metadata is written. Therefore, only server location information (eg, URL information) needs to be included in the manifest file 340 . In other words, the manifest file 340 may only need to include server location information, and does not need to include disc ID information and language code information. Therefore, the size of the manifest file 340 may be about 8K bytes (=256 bytes×32), in which case the maximum storage capacity required to store 1000 manifest files 340 is about 8M bytes. As a result, a small memory device such as flash memory can be used instead of a hard disk. Therefore, a reproducing device 400 having a small storage capacity (for example, a reproducing device having a flash memory instead of a hard disk) can still provide metadata in multiple languages.

6 is a block diagram for explaining a method of providing metadata in multiple languages using representative metadata in which language-independent metadata that can be written in a common language is used according to an exemplary embodiment of the present invention. The section set as representative metadata. Referring to FIG. 6, metadata may be classified into language-dependent parts and language-independent parts. For example, language-dependent parts of metadata (e.g., actor or actress name, disc title, and content manufacturer's name) are content that can be input in different languages by a content provider and, therefore, can be stored as separate metadata files, that is, first to fourth language-related metadata files 610 to 640 . On the other hand, the language-independent portion of the metadata is stored as a common metadata file 650 . The language-independent parts included in the common metadata file 650 may include: content runtime, audio file type and spatial resolution provided by the disc 410 expressed identically regardless of language, selected from a list and may be represented as shown in FIG. 4 The reproduction device 400 mechanically translates the genre information.

The common metadata file 650 includes common data that can be reproduced from any one of the language-dependent metadata files 610, 620, 630, 640 on the disc 410 regardless of the language of reproduced content. Accordingly, common metadata file 650 may be designated as a representative metadata file. Language code information on the first to fourth language-related metadata files 610 to 640 may also be included in the common metadata file 650 . The language-dependent part of the metadata for another language (from the first to fourth language-related metadata files 610 to 640 not available) may be additionally downloaded from other storage media or from a remote server over a network for additional Languages can be supported.

7A and 7B are views for explaining a method of providing metadata in multiple languages using multiple parameter sets under a descriptor according to an exemplary embodiment of the present invention. 7A and 7B, metadata may be represented in the form of a metadata file 700 that includes a header 710 and a plurality of descriptors 720A-720N, each of which includes a Multiple parameter sets. As a result, multiple language settings for each descriptor are generated in multiple languages supported by an information storage medium such as the disc 410, instead of storing multiple versions of metadata written in multiple languages as separate metadata files. For example, the descriptor "actors/actresses" could include: a Korean parameter set including the names of multiple actors written in Korean, for example, Jackie Chan, Chris Tucker, Tom Wilkinson, and Tzi Ma; an English parameter including actors written in English names; and a Chinese parameter set, including actors' names written in Chinese. Multiple descriptors 720A-720N, each including multiple parameter sets written in multiple languages, may compose a single metadata file 700 available on an information storage medium such as disc 410 as shown in FIG. 4 . In addition, as shown in FIG. 4 , parameter sets written in languages other than the plurality of languages may also be downloaded from a remote server 420 through a network. In this way, the metadata file 700 can be updated in units of descriptors. When the metadata file 700 is updated, update information may be stored in the header 710 of the metadata file 700 . For example, referring to FIG. 7A , if a Japanese parameter set and a French parameter set are added to the descriptor 'actors/actresses', information about the added language may be recorded in the header 710 of the metadata file 700 .

In the method shown in FIGS. 7A and 7B , it is easy to determine whether various sets of parameters written in multiple languages represent the same thing. For example, in the method shown in FIG. 7A and FIG. 7B, the name of actor Jackie Chan written in different languages (e.g., English, Chinese, and Korean) can be classified as belonging to different parameter sets under one descriptor , making it easy to determine whether actors' names written in different languages refer to the same person. As a result, the possibility of determining multiple versions of metadata written in multiple languages as different metadata can be reduced.

In conclusion, according to the methods shown in Figs. 3, 6 and 7A, 7B, metadata can also be easily updated. In other words, according to the methods shown in FIGS. 3, 6 and 7A, 7B, metadata can be easily updated in the following ways: (1) As described in conjunction with FIG. A plurality of metadata files; (2) as described in conjunction with FIG. 6, download a plurality of language-related metadata files from each server; or alternatively, (3) as described in conjunction with FIGS. 7A-7B, download from each server Multiple parameter sets under descriptors written in multiple languages. In the case of updating metadata, disc ID information can be used to identify a disc, and additional ID information or URL information can be used to manage version information of metadata that can be updated.

FIG. 8 is a system diagram for updating metadata using an information storage medium and a manifest file stored on a server according to an embodiment of the present invention. Referring to FIG. 8 , the system includes: a reproduction device 800 , an information storage medium 810 and a remote server 820 . The reproducing apparatus 800 is provided with a memory (ie, a local storage unit) 802 and a search mechanism (not shown) to allow a user to search for content with reference to metadata. The manifest file 340 stored on the information storage medium 810 (eg, disk) includes URLs on a plurality of servers accessible through the network, and the manifest file 340 stored in the remote server 820 includes a list of languages that can be supported. Accordingly, metadata written in one of the listed languages may be selected and downloaded from the server 820 . For example, if the user has stored the English version of metadata on the information storage medium 810 and wishes to download another version of the metadata written in a language other than English (for example, Japanese or Korean) stored elsewhere , the user can use the manifest file 340 stored in the remote server 820 to check the list of websites that are created in languages other than English and that can be downloaded from the website in languages other than English Multiple versions of metadata authored. Then, the user can download the metadata file by selecting and downloading any one of various versions of metadata written in various languages other than English. Similarly, metadata classified into language-dependent parts and language-independent parts as described in connection with FIG. 6, and metadata files including descriptors as described in connection with FIGS. way is updated.

Various embodiments of the present invention for processing metadata can be written as computer programs, and can be implemented in general-purpose digital computers that execute the programs by using a computer-readable recording medium. Examples of the computer-readable recording medium include magnetic storage media (for example, ROM, floppy disk, hard disk, etc.), optical recording media (for example, CD-ROM, DVD, etc.), and media such as carrier waves (for example, transmission via the Internet) storage medium. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. In addition, functional programs, codes, and code segments for realizing the present invention can be easily deduced by programmers in the field to which the present invention pertains.

While there has been shown and described what are considered to be exemplary embodiments of the present invention, it will be understood by those skilled in the art that various changes and modifications in form may be made therein without departing from the spirit and scope of the invention. , and its components may be replaced by equivalents. For example, other computer-readable media, such as read-only memory ( ROM), random access memory (RAM), CD-ROM, magnetic tape, floppy disk, optical or data storage device, and carrier wave. Likewise, the central controller may be implemented as a chipset, or alternatively, as a general or special purpose computer programmed to perform the methods described with reference to Figures 3, 6 and 7A-7B. Therefore, it is intended that the invention not be limited to the various exemplary embodiments disclosed, but that the invention will include all embodiments falling within the scope of the claims.
