Auxiliary content delivery module that delivers ancillary content, such as subtitle files, to your systems 20, 22, and / or 24 Module 108.

In addition, the system 100 of the present invention efficiently stores and manages a content key / secondary content key database 144 and a plurality of auxiliary content for storing and operating content and auxiliary content keys that specify content and auxiliary content therefor. And an auxiliary content database 146 such as a subtitle file. Of course, the content key / auxiliary content key database 144 and the sub content database 146 such as a subtitle file may be implemented in physically the same storage device.

Further, the system 100 may include various hardware 140 included in the conventional computer system and various software 142 executed using the same, and perform a function performed by the conventional computer system. Accordingly, the system 100 of the present invention may be implemented as an online server such as a wired / wireless web server that can be connected through a wired or wireless internet, and in this case, a plurality of web pages as a kind of the software 142. It should be noted that each module may be implemented as a component of the web page. The implementation of the databases 144 and 146, hardware 140 and software 142 is already well known in the art and will be omitted.

Hereinafter, the modules will be described in more detail. First, the content key / auxiliary content key database 144 will be described. The content key / auxiliary content key database 144 has a content key table and an auxiliary content key table corresponding to each content and auxiliary content. 4 is a diagram illustrating an example of a content key table stored in a content key / auxiliary content key database 144 of the auxiliary content management system 100 such as a caption file related to the multimedia content of FIG. 2.

According to the present invention, a plurality of elements constituting a content key capable of specifying the content are provided, thereby enabling a highly accurate and efficient search and management service. In this embodiment, the content is a video material. As shown in FIG. 4, each content key table of the content key / auxiliary content key database 144 includes a serial number field, a title field, a registration date field, a file name field, and a file size. Field, check sum field, format field, playback time field, screen size field, subscriber comment field, and subtitle language field.

The serial number field stores serial numbers assigned in a predetermined order in which each content is stored in the content key / auxiliary content key database 144. The title field stores the title of the content, and the registration date field stores the date when the content is stored in the content key / secondary content key database 144.

The file name field stores a file name except an extension of the content file, and the file size field stores a file size of the content file. The checksum field stores a result of obtaining a predetermined checksum for the content file, and the format field stores information about the format of the content file, that is, the extension.

In addition, the playback time field stores the total playing time when the content is played by a predetermined player, and the screen size field stores the horizontal and vertical sizes displayed on the screen when the content is played.

The registrant comment field stores a comment by which the content key registered details the content. Finally, the subtitle language field stores information about which language (eg, Korean or English) the subtitle is written.

Next, the auxiliary content key table will be described with reference to FIG. 5. As described later, the auxiliary content key is information necessary for searching for auxiliary content such as a subtitle file that is efficient and accurate when registering auxiliary content such as a subtitle file.

FIG. 5 is a diagram illustrating an example of an auxiliary content key table stored in the content key / auxiliary content key database 144 of the auxiliary content management system 100 such as a caption file related to the multimedia content of FIG. 2. According to the present invention, similarly to the content key, a plurality of elements constituting the auxiliary content key capable of specifying auxiliary content such as a subtitle file can be provided, thereby enabling a highly accurate and efficient search and management service.

As shown in Fig. 5, each secondary content key table of the content key / secondary content key database 144 includes a serial number field, a content serial number field, copyright information, a registrant ID field, a registration date field, a file size field, a checksum field, a registrant. It may include a comment field and a subtitle language field.

In the content serial number field, the serial number of the content corresponding to the auxiliary content such as the subtitle file is stored, and the copyright information stores information such as the name of the producer who produced the auxiliary content such as the subtitle file or the homepage thereof. The registrant ID field stores a unique identifier of the registrant who registered auxiliary content such as a subtitle file. Other fields have a similar role to each of the fields in the content key table, and thus description thereof will be omitted.

Information about auxiliary content such as content and subtitle files stored in the content key / auxiliary content key database 144, that is, content key and auxiliary content keys may be generated and stored by an operator of the system 100, as described below. A content key and an auxiliary content key may be received from a user and stored and managed. According to the present embodiment, the system 100 receives a content key and an auxiliary content key from a user, and stores and manages the content key and the auxiliary content key database 144.

Next, the user side module operation module 102 installs and controls the operation of the user side module 120 which interacts with the system 100 of the present invention and transmits and receives information necessary for obtaining auxiliary content such as a subtitle file requested by the user. The user module 120 may be implemented as a plug-in suitable for a browser of the user system using a method such as Active X control, Java, or Java script, or the user It may be implemented as a separate independent application program suitable for the system, or may be implemented in combination.

Next, the user-side module 120 includes a content key generation unit 122. The content key generation unit 122 generates a content key specifying content corresponding to auxiliary content such as a subtitle file that the user wants to use. That is, the content key generation unit 122 transmits the content to the content stored in the predetermined storage device of the system 20 to 28 of the user so as to transmit information for searching for the auxiliary content such as the subtitle file desired by the user to the system 100. Create a key. According to the present invention, the content key generation unit 122 generates the content key using the binary checksum, the content file size, the content file playing time, the content file format, the content file name, and the like.

Here, binary checksum is a good way to compare and search the same data, but it can handle the checksum from the beginning to the end of the file, but in this case it is inefficient in time, so it is preferable to generate the key by checking only the beginning of the file. . In the present embodiment, the MD5 checksum is used in various checksum methods, and a 16-byte MD5 checksum is generated for 1MB of the front part of the file. If the total file size is 1MB or less, a method of generating an MD5 checksum for the entire file may be adopted.

In the case of a video content file, since the file size is extremely rare, the file size (that is, the total capacity of the file) can be used as the content key. In addition, as described above, the information on the playback time of the content file, the format of the content file, that is, the information on the file extension (for example, AVI, MPG, ASF, WMV, etc.), information on the file name, etc. It can be used as a key.

Next, the content key receiving module 104 receives the content key of the content corresponding to the auxiliary content such as a subtitle file that the user wants to use generated by the content key generation unit 122 of the user side module 120.

Next, the content key retrieval extraction module 106 retrieves whether a content key identical or similar to the content key received by the content key receiving module 104 exists in the content key / auxiliary content key database 144 and extracts the corresponding content key. Here, the content key retrieval extraction module 106 stores information about the received content key value, that is, the binary checksum, the content file size, the content file playing time, the content file format, the content file name, and the like, as described above, and the content key / secondary content key database 144. The content key values stored in the table of contents are compared and searched. In addition, according to the present invention, the content key search extraction module 106 can be provided to the user by extracting the same content key value as well as the case of having a similar content key value using a variety of content key values, For example, if there is no exactly the same title or file name, the inefficiency of not being able to use auxiliary content such as the subtitle file is eliminated.

In addition, the content key retrieval extraction module 106 retrieves the similarity of the content key by assigning different weights to each component of the content key. 6 is a table illustrating a relationship between each content key value and a weight value when the content key retrieval extraction module 106 of the auxiliary content management system 100 such as the caption file relating to the multimedia content of FIG. 2 determines the similarity of the content key. Example.

As shown, in the present embodiment, a weight of 20% is assigned to a file size, a checksum, a format, and a reproduction time among content key values, and a weight of 10% is assigned to a file name and a screen size. That is, usually, when a content key value has a higher influence on determining the similarity of content, the content key value is weighted higher.

For example, it is assumed that an MPG file and a WMA file having the same file name and the same playback time have 40% similarity to each other. As another example, a partial AVI file that has not been properly transferred to the back of the file during transfer has 80% similarity between each other if the binary checksum, format, filename, screen size, and content playback time are the same as, for example, an MPG file. Shall be. On the contrary, according to the present embodiment, it is determined that two content files having different checksums, file formats, and screen sizes are not similar to each other.

Next, the auxiliary content delivery module 108 has the same and / or similar content key as the content key of the content having the content key extracted by the content key retrieval extraction module 106, that is, the content corresponding to the auxiliary content such as a subtitle file desired by the user. Information about auxiliary content such as a subtitle file corresponding to the content having a key and / or auxiliary content such as the subtitle file is transmitted to the user system. In addition, when a plurality of the same and similar content keys exist, the auxiliary content transmission module 108 such as a subtitle file first transmits information about auxiliary content such as a plurality of subtitle files corresponding to the content key to the user system for the user's selection. If the user confirms this and selects one or more of them, the auxiliary content such as the selected subtitle file may be transmitted. This will be described with reference to FIG. 7. FIG. 7 illustrates a screen in which information about auxiliary content, such as a plurality of subtitle files, is displayed on a user system when a plurality of identical and similar content keys exist. As shown. Briefly displays information on file size, checksum, and playback time, which are information of content corresponding to auxiliary content, such as subtitle files desired by the user, and similarity, copyright, and registrants, which are information on auxiliary content, such as a plurality of corresponding subtitle files. ID, file size and comments are displayed. Therefore, the user can select the auxiliary content such as the desired subtitle file after confirming the information.

Meanwhile, according to the present invention, in order to enable the user to register auxiliary content such as a subtitle file, the user module 120 generates auxiliary content key for specifying auxiliary content such as subtitle file that the user wants to register. Further including key generation unit 124 (see FIG. 3), content key generation unit 122 further generates a content key specifying multimedia content corresponding to auxiliary content such as a subtitle file that the user wants to register.

In addition, the system 100 may further include a content key received by the auxiliary content key receiving module 110, the content key receiving module 104, and / or the auxiliary content key receiving module 110 receiving the auxiliary content key generated by the auxiliary content key generating unit 124. A search of the content key / secondary content key search module 112 and the content key / secondary content key search module 112, which retrieves from the content key / secondary content key database 144 the presence of the same content key and / or secondary content key as the secondary content key. According to a result, the auxiliary content registration module 114 further receives auxiliary content such as a subtitle file from the systems 20 to 28 of the user who wants to register the auxiliary content and stores the auxiliary content in the auxiliary content database 146 such as a subtitle file to register the auxiliary content. do.

Furthermore, the system 100 searches for and extracts another auxiliary content corresponding to the content having a predetermined content key from the auxiliary content database 146 such as a subtitle file according to the search result of the content key / secondary content key retrieval module 112. And similar similar content delivery module 116 for transmitting to systems 20-28. Such a configuration enables to implement not only a service for providing auxiliary content such as a subtitle file to a user but also a service that enables registration of auxiliary content such as a subtitle file. Each module will be described in detail below.

First, the auxiliary content key generation unit 124 of the user side module 120 generates an auxiliary content key for specifying auxiliary content that is information necessary for searching for auxiliary content such as a caption file. In this case, the auxiliary content key generation unit 124 checksums the auxiliary content that is the subject of registration stored in the predetermined storage device of the system 20 to 28 of the user who wants to register auxiliary content such as a subtitle file, similarly to the content key generation unit. And the secondary content key using the file size. Since the auxiliary content has a smaller file size than the content file, the MD5 checksum is processed for the entire file. If the file is larger than 1MB, it is not a normal file.

Meanwhile, the content key generation module 122 of the user module 120 searches for a content corresponding to auxiliary content such as a subtitle file to be registered from a predetermined storage device and generates a content key for specifying the content. Since the operation of generating the content key by the content key generation module 122 has been described above, a description thereof will be omitted.

The auxiliary content key receiving module 110 receives an auxiliary content key that specifies auxiliary content such as a subtitle file that a user wants to register, generated by the auxiliary content key generating unit 124 of the user side module 120.

Next, the content key / auxiliary content key retrieval module 112 determines whether there is a same content key as the content key specifying the content corresponding to the auxiliary content that the content key receiving module 110 wants to register, and the auxiliary content key receiving module 110. The content key / auxiliary content key database 144 searches whether there is an auxiliary content key identical to the received auxiliary content key.

The auxiliary content registration module 114 determines whether to register auxiliary content such as a subtitle file to be registered by the user according to the search result of the content key / secondary content key search module 112. That is, the auxiliary content registration module 114 does not register auxiliary content such as a subtitle file when the same auxiliary content key already exists in the content key / secondary content key database 144. In this case, the auxiliary content registration module 114 such as a caption file may transmit the effect to the systems 20 to 28 of the user.

In addition, if the auxiliary content registration module 114 such as a caption file does not exist and the same content key does not exist, the auxiliary content registration module 114 receives an auxiliary content such as a caption file from the user system. Stored in the content database 146. In this case, the auxiliary content registration module 114, such as a subtitle file, registers auxiliary content such as a subtitle file, information about auxiliary content such as the subtitle file, that is, a content key and auxiliary information received from the user's system 20 to 28. It is preferable to store the content key in the content key table and the auxiliary content key table of the content key / auxiliary content key database 144 so that it can be used for retrieval of auxiliary content such as a subtitle file later.

On the other hand, if the similar auxiliary content transmission module 116 does not have the same auxiliary content key but the same content key exists, the similar auxiliary content transmission module 116 searches for and extracts auxiliary content such as another subtitle file corresponding to the content having the same content key, and then stores the subtitle file. It may be transmitted to the system 20 to 28 of the user who wants to register the auxiliary content and information about it. In this case, the auxiliary content registration module 114 such as a subtitle file checks the auxiliary content such as another subtitle file and its information, and then provides information on the difference between the auxiliary content such as a subtitle file and the auxiliary content such as another subtitle file. It can be received and stored as an auxiliary content key along with auxiliary content such as a subtitle file.

Next, an auxiliary content management method such as a subtitle file or the like relating to multimedia content according to an embodiment of the present invention will be described in detail. 8A to 9B are flowcharts schematically illustrating a method for managing an auxiliary content such as a subtitle file related to multimedia content according to an embodiment of the present invention. FIG. 8A is a flowchart illustrating a process performed in user systems 20 through 28 and providing auxiliary content to user systems 20 through 28. FIG. 8B is a process performed in the system 100 and is a flowchart illustrating a process of providing auxiliary content to the user systems 20 to 28. FIG. 9A is a flowchart illustrating a process performed in user systems 20 through 28 and registering auxiliary content in system 100. FIG. 9B is a flowchart illustrating a process performed in the system 100 and registering auxiliary content in the system 100.

Referring to FIGS. 8A and 8B, first, in system 20 to 28 of a user who wants to use auxiliary content, a content key specifying content corresponding to the desired auxiliary content is generated (step S202), and transmitted to system 100 (step S202). Step S204).

In response to this, the system 100 receives the generated content key (step S302) and searches the database for the existence of the same content key (step S304). Next, the system 100 determines whether the same content key exists (step S306), and if the same content key exists, transmits a list of corresponding auxiliary contents to the user systems 20 to 28 (step S308).

In contrast, the user systems 20 to 28 receive a list of auxiliary content from the system 100 (step S206), display a list of the received auxiliary content, and select the auxiliary content to be transmitted from the user (step S208), The system 100 requests to transmit the selected auxiliary content (step S210).

In contrast, when the system 100 receives the request for transmitting the auxiliary content from the user systems 20 to 28 (step S310), the system 100 extracts the auxiliary content from the database and transmits the auxiliary content to the user systems 20 to 28 (step S312).

On the other hand, the system 100 determines whether the same content key exists (step S306). If the same content key does not exist, the system 100 searches for a content key similar to the received content key (step S314). If a similar content key exists, a list of corresponding similar auxiliary contents is sent to the user systems 20 to 28 (step S308). The following process is the same as the above steps 206 to S212 and S310 to S312 except that the auxiliary content is changed to similar auxiliary content, and thus description thereof will be omitted.

Next, a process of registering the auxiliary content by the user will be described. 9A and 9B, first, in the user systems 20 to 28, an auxiliary content key for specifying auxiliary content to be registered and a content key for specifying content corresponding to the auxiliary content are generated (step S402), and the system is generated. Transfer to 100 (step S404).

In contrast, the system 100 receives the content key and the auxiliary content key from the user systems 20 to 28 (step S502), so as to retrieve from the database whether the same content key and the auxiliary content key as the received content key and the auxiliary content key exist. (Step S504). Next, when the system 100 determines that the same auxiliary content key exists (step S506), the system 100 transmits the effect to the user systems 20 to 28 (step S508), and the process ends.

In contrast, when the user systems 20 to 28 receive information indicating that the same auxiliary content key exists from the system 100 (step S4062), the user system displays the message so that the user can see it (step S4082), and the process is completed.

On the other hand, when the system 100 determines that the same content key exists but another auxiliary content key exists (step S510), the system 100 transmits the auxiliary content having the other auxiliary content key and information about it (step S510). S512).

In contrast, when the user systems 20 to 28 receive the auxiliary content having the other auxiliary content key and the information about it from the system 100 (step S4064), the user system 20 to 28 displays the other auxiliary content and the information to the user, and assists the user to register. By checking the difference from the content (step S4084), the auxiliary content to be registered and information about it are transmitted to the system 100 (step S410), and the process is completed.

On the other hand, when the system 100 receives the auxiliary content to be registered from the user systems 20 to 28 and information on it (step S514), the system 100 registers the received auxiliary content by storing it in a database (step S516), and the process is completed. .

On the other hand, if the system 100 does not have the same content key and the same auxiliary content key as a result of the search (step S510), the system 100 provides information for requesting to transmit the auxiliary content to be registered in the user systems 20 to 28 and related information. Transfer (step S518).

In contrast, when the user systems 20 to 28 receive a request for transmission of auxiliary content to be registered from the system 100 and related information (step S4066), the user system displays the effect to the user and allows the user to confirm ( Step S4086). The subsequent process is the same as the steps 4084 to S410 and steps S514 to S516, and a description thereof will be omitted.

On the other hand, although not shown, the auxiliary content management method according to an embodiment of the present invention, when a user who wants to use and / or register auxiliary content accesses the auxiliary content management system 100, the system 20 to 28 of the user. The method may further include checking whether a user-side module for generating a content key and / or an auxiliary content key is installed, and if not installed, installing the content key and / or the auxiliary content key in the system 20 to 28 of the user.

Next, another Example of this invention is described. 10 is a block diagram schematically illustrating a configuration of a user module 120 according to another embodiment of the present invention. As shown, the user side module 120 according to the present embodiment includes a reproduction control unit 126 and an automatic registration setting unit 128 in addition to the content key generation unit 122 and the auxiliary content key generation unit 124 of the above embodiment. Except for the reproduction control unit 126 and the automatic registration setting unit 128, the description of the same matters as in the above embodiment will be omitted.

The system 100 according to the present embodiment allows the auxiliary content corresponding to the content to be played back automatically during the playback of the content, and also enables the auxiliary content corresponding to the content being played back to be automatically registered in the system 100 during the playback. . Hereinafter, the configuration of the user module 120 according to the present embodiment will be described in detail.

When the content is played back in the user systems 20 to 28, the playback control unit 126 controls the playback of the content for automatic playback of the auxiliary content corresponding to the content to be played back. That is, in the case of automatic playback of auxiliary content, the playback control unit 126, when the content is played back in the user systems 20 to 28 by the user's command, stops the playback of the corresponding content until the corresponding auxiliary content is provided from the system 100.

In addition, when the auxiliary content is provided, the reproduction control unit 126 resumes the reproduction of the content, and causes the supplied auxiliary content to be reproduced in synchronization with the content.

In the case of the automatic registration of the auxiliary content, the automatic registration setting unit 128 allows the user to set in advance that the auxiliary content is automatically registered in the system 100 at the time of reproduction of the corresponding content, and stores information on this. In addition, the automatic registration setting unit 128 may set the system 100 to automatically perform registration without receiving confirmation of the information on the registered items from the user, even during the registration process.

Next, an auxiliary content management method according to another embodiment of the present invention will be described. 11 is a flowchart illustrating an automatic playback process of auxiliary content performed in user systems 20 to 28.

Referring to Fig. 11, when predetermined content is played back in the user systems 20 to 28 by the user's playback command in the user systems 20 to 28 (step S201), the playback control unit 126 of the user module 120 performs playback of the content. On a temporary basis, the content key generation unit 122 generates a content key of the content to be played back (step S2022). Subsequent processes are the same as steps S204 to S210 of FIG. 8A and steps S302 to S312 of FIG. 8B, and thus description thereof will be omitted.

Next, when the transmission control unit 126 of the user side module 120 receives the transmission of the auxiliary content or the similar auxiliary content from the system 100 to the user systems 20 to 28 (step S212), playback of the held content resumes, and the received auxiliary The content or the similar auxiliary content is reproduced in synchronization (step S214).

Next, an auxiliary content management method according to another embodiment of the present invention will be described. 12 is a flowchart illustrating an automatic registration process of auxiliary content performed in user systems 20 to 28.

12, first, in the user systems 20 to 28, the automatic registration setting unit 138 of the user side module 120 sets the user to automatically register the auxiliary content in the system 100 during reproduction of the corresponding content (step S4012). .

Next, when there is a playback instruction of the content by the user in the user systems 20 to 28 (step S4014), the content key generation unit 122 and the auxiliary content key generation unit 124 are respectively connected to the content being played and the auxiliary content played in synchronization with it. A content key and an auxiliary content key are generated (step S4022). The subsequent process is the same as the steps S404 to S410 of FIG. 9A and the steps S502 to S516 of FIG. 9B, and thus description thereof will be omitted.

Meanwhile, as another embodiment, in steps S404 to S410 of FIG. 9A and steps S502 to S516 of FIG. 9B, registration is uniformly performed in advance without checking whether a user newly registers auxiliary content in the system 100. It may be specified in advance (for example, it may be performed in step S4012), and in this case step S4084 may be omitted.

As mentioned above, although preferred embodiment was described about this invention, it is clear that the technical idea of this invention is not limited to this and should be interpreted based on a claim.

According to the present invention, since the content key and the auxiliary content key can be searched for the same case as well as similar content, it is possible to provide auxiliary content such as a subtitle file related to the multimedia content efficiently and uniformly and with high reliability. It is possible to register.

Further, according to the present invention, auxiliary content such as a subtitle file corresponding to the content being played back can be automatically played back during the playback of the content.
