Best Mode for Carrying Out the Invention [28] Hereinafter, the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. [29] The term "a personal information processor" refers to a terminal such as MP3 player, handheld PC, electronic dictionary, and portable phone including a memory means and a microprocessor having a calculation function. [30] A caption information providing method and a system thereof according to the present invention will now be described referring to the accompanying drawings.
[31] FIG. 1 is a view showing a network connection of a client terminal, a caption server, and a personal information processor according to an embodiment of the present invention.
[32] A user can receive multimedia contents 111 from a contents providing system 130 by using a client terminal 110. The client terminal 110 transmits a caption information query associated with the multimedia contents 111 to a caption server 120. The client terminal 110 receives an acknowledge response from the caption server 120 as a response to the caption request query. The client terminal 110 combines the caption information with the multimedia contents 111 to generate contents-caption information, and transmits the contents-caption information to a personal information processor 140 connected to the client terminal 110.
[33] FIG. 2 is a flow chart showing a caption providing method performed by a client terminal 110 according to an embodiment of the present invention.
[34] In step 201, the client terminal 110 receives multimedia contents from the contents providing system 130. The contents system 130 may be a server, which runs at least one web site capable of uploading/downloading sound source files or moving image files. The sound source files or the moving image files are files that the personal information processor 140 can execute.
[35] According to an embodiment of the present invention, multimedia contents may be multimedia contents encrypted by a Digital Rights Management (referred to as "DRM" hereinafter) module. There are sound source files such as MP3, WMA, AAC, MID, RA, or MP4 having a predetermined contents identifier, or moving image files such as AVI, MPG, RAM, or RM having a predetermined contents identifier as an example of the multimedia contents.
[36] DRM is a technique that stably protects a contents provider's rights and profits, prevents illegal copying, and supports all the management procedures such as a levy of a usage fee and settlement execution from generation of contents to circulation thereof. The DRM includes a digital copyright management that allows legal users to use the contents and pay a usage fee, software and security technique for copyright approval and execution, and payment/settlement technique.
[37] Furthermore, the DRM is supported by Digital Object Identifier (DOI), INDECS, and watermarking technique. The DOI is a contents identifier, which is given to digital contents. Watermarking is a technique to identify who is a digital copyright holder when a dispute of a copyright occurs after secret information was hidden in digital data. The DRM prohibits a user from using the contents when the user does not pay a usage fee by installing security authorization system every contents.
[38] In step 202, the client terminal 110 extracts a predetermined contents identifier included in the received multimedia contents. In this case, the client terminal 110
decrypts at least a part of the multimedia contents by a predetermined decrypting module to extract a contents identifier.
[39] Further, according to an embodiment of the present invention, unlike the aforementioned description, in step 202 of extracting predetermined contents included in the multimedia contents, the client terminal 110 may extract the contents identifier from head information included in a DRM module, which encrypts the multimedia contents without a decrypting operation. That is, upon using DRM head information as an embodiment of the present invention, a decrypting procedure may be unnecessary.
[40] According to another embodiment of the present invention, the extracted contents identifier is a unique identifier given in a predetermined manner through a web site managed by the contents providing system 130 associated with multi-media contents. Each contents identifier is used to uniquely identify each multimedia contents. In this case, a unique file name of the multi-media contents given from the web site managed by the content providing system 130 may be used as the contents identifier. As will be described later, the contents identifier can be used to extract caption information and additional contents information by the caption server 120.
[41] According to a further embodiment of the present invention, the step 202 of extracting the contents identifier includes the sub-steps of extracting a predetermined contents identifier included in the received multi-media contents, and extracting a site identifier included in the multi-media contents. The site identifier is a unique identifier to identify a web site associated with the contents providing system 130. For example, the client terminal 110 extracts an identifier of 'A7321MB' from contents distributed from a web site A, and can identify that the contents are contents received from the web site A based on the extracted identifier of 'A7321MB'. Further, the client terminal 110 extracts an identifier of 'B5394MB' from contents distributed from a web site B, and can identify that the contents are contents received from the web site B based on the extracted identifier of 'B5394MB'. As will be explained below, a use of the extracted site identifier causes the caption information to be easily extracted.
[42] In step 203, the client terminal 110 transmits a caption request query including a contents identifier to request caption information associated with the multi-media contents.
[43] In step 204, the caption server 120 receives the caption request query from the client terminal 110 over a communication network, and transmits caption information associated with the content identifier in response to the reception thereof.
[44] In step 205, the client terminal 110 receives an acknowledge response including the caption information from the caption server 120.
[45] In accordance with an embodiment of the present invention, in steps 203 through
205, the client terminal 110 transmits a caption information query obtained by adding
the site identifier to the caption request query including the content identifier. The caption server 120 receives the caption information query from the client terminal 110, and transmits an acknowledge response including the caption information to the client terminal 110 in response to the reception thereof. The client terminal 110 receives an acknowledge response including caption information associated with the content identifier and the site identifier. That is, when the caption server 120 maintains the caption information based on the site identifier as well as the contents identifier, it searches the caption information using the site identifier more simply and transmits the caption information to the client terminal 110.
[46] In step 206, the client terminal 110 generates contents-caption information by associating the received caption information with the multi-media contents. Namely, the client terminal 110 combines the received caption information with the multi-media contents to generate one contents-caption information.
[47] In step 207, the client terminal 110 encrypts the generated contents-caption information in a predetermined manner through a encrypting module, and transmits the encrypted contents-caption information to the personal information processor 140.
[48] FIG. 3 is a flow chart showing a caption providing method performed by a caption server according to an embodiment of the present invention.
[49] In step 301, the caption server 120 stores a database including caption information associated with the contents identifier.
[50] FIG. 4 is a view showing a construction of a database 400 including caption information associated with a contents identifier according to and embodiment of the present invention. As shown in FIG. 4, the database 400 includes contents identifier 401, a caption identifier 402, caption information 403, and additional contents 404.
[51] The contents identifier 401 is a unique identifier given in a web site managed by the contents providing system 130 associated with multi-media contents. When the caption server 120 receives a caption request query including a contents identifier from the client terminal 110, it extracts the contents identifier 401 of the database 400 and caption information based on the contents identifier 401.
[52] The caption identifier 402 is an identifier to identify caption information to associate with the contents identifier 401. According to an embodiment of the present invention, the caption information 403 may be a lyric or text file of hexa, binary, or Unicode format. According to another embodiment of the present invention, the caption information 403 may be a path of a caption information file in which caption information is located.
[53] On the other hand, the additional contents 404 may be all kinds of multi-media data such as main image, music information, and artist image of album, which corresponds to multi-media contents associated with the contents identifier 401.
[54] According to an embodiment of the present invention, the caption server 120 may receive contents information with respect to added/updated multi-media contents from a predetermined contents providing system 130 connected thereto over a communication network. In this case, the contents information includes a contents identifier corresponding to the added/updated multi-media contents. For example, the caption server 120 receives contents information indicates that a singer 'LEE Soo- Young's new song 'Goodbye' is added as new sound source contents. In this case, for example, the contents information may include 'B2005SYMB', which is a contents identifier of the added sound source contents.
[55] The caption server 120 can generate caption information corresponding to the added/updated multi-media contents, and add/update it in the database 400 to associate with the contents identifier.
[56] Further, the caption server 120 may add/update the caption information in the database 400 at predetermined time intervals, namely, by times, by dates, by weeks or based on addition/update period set according to the number of the added/updated multi-media contents.
[57] In step 302, the client terminal 110 transmits a caption request query including the content identifier to the caption server 120 over a communication network.
[58] In step 303, the caption server 120 receives the caption request query from the client terminal 110.
[59] In step 304, the caption server 120 extracts caption information corresponding to the received contents identifier based on the database 400 in response to the caption request query.
[60] For example, when the caption server 120 receives a caption request query including the contents identifier 'A1032MISAMB', it may identify a contents identifier corresponding to the contents identifier 'A1032MISAMB' based on the contents identifier 401 of the database 400, and extract 'misalyrics.bin' of the caption information 403 corresponding to the contents identifier. Moreover, when the identified contents identifier is 'Gv321BRMV, the caption server 120 can extract caption information through a path '/home/mv/gloomy.txt' of a caption information file of the caption information 403 corresponding thereto.
[61] Hereinafter, another embodiment of the present invention will be explained with reference to FIG. 5 and FIG. 6.
[62] FIG. 5 is a flow chart showing a method for extracting caption information by a caption server using a database according to an embodiment of the present invention.
[63] In step 501, the caption server 120 maintains a caption query table including a caption identifier corresponding to each contents identifier.
[64] FIG. 6 is a view showing an example of the caption query table 600 maintained by a
caption server 120 according to an embodiment of the present invention. As shown in FIG. 6, the caption query table 600 includes fields of the contents identifier 601 and the caption identifier 602. The contents identifier 601 can be obtained by mapping at least one contents identifier and one caption identifier. At least one contents identifier may be a unique identifier given from a plurality of different web sites.
[65] In step 502, when the caption server 120 receives the caption request query, it identifies a caption identifier 602 corresponding to a contents identifier 601 included in the caption request query using the caption query table 600. For example, when the caption server 120 receives a caption request query including a contents identifier 'A1032MISAMB', it can identify a caption identifier '@34M532DR' based on the contents identifier 601 of the caption query table 600 shown in FIG. 6.
[66] In step 503, the caption server 120 extracts caption information corresponding to the identified caption identifier from the database 400. For example, the caption server 120 may search the caption information corresponding to the identified caption identifier '@34M532DR' from the database 400 of FIG. 4, and extract 'misalyrics.bin', which is a corresponding caption information.
[67] According to another embodiment of the present invention, in steps 502 and 503, when the caption server 120 receives the caption request query, it may identify the caption identifier 602 corresponding to the contents identifier 601 included in the caption request query using the caption query table 602, and extract caption information and additional contents corresponding to the identified caption identifier 602 from the database 400. For example, when the caption server 120 receives a caption request query including the contents identifier 'C3016GODMB', it can identify a caption identifier '@ 52Ml 34 IRP' based on the contents identifier 601 of the caption query table 600 shown in FIG. 6. Furthermore, the caption server 120 may search caption information and additional contents corresponding to the identified caption identifier '@ 52Ml 34 IRP' from the database 400 of FIG. 4, and extract the caption information '/home/Lyric/godlyrics.txt' and the additional contents 'godmain.jpg' image therefrom.
[68] In step 305, the caption server 120 transmits an acknowledge response including the extracted caption information to the client terminal 110. In this case, according to another embodiment of the present invention, the caption server 120 may transmit additional contents besides an acknowledge response including the caption information to the client terminal 110.
[69] In step 306, the client terminal 110 receives the acknowledge response including the caption information from the caption server 120.
[70] According to the aforementioned operation of the present invention, because the client terminal receives caption information from the caption server based on contents
