As the amount of content increases, there is a need for technology that can improve the usability and accessibility of the customers. To this end, efforts are being made to provide a personalized UI / UX (User Interface / User Experience) environment for each customer. Typical examples include content search / recommendation service reflecting individual use tendency, target advertisement service, and service that can be used to search contents on various terminals by querying usage history for each customer.

Currently, domestic VOD operators provide services that allow subscribers to watch domestically produced broadcasting contents at any time by organizing live broadcasting channels into VOD services immediately after broadcasting. It is provided in real time broadcasting or VOD format on the screen.

In order to provide a personalized UI / UX environment for each customer, various log analysis such as VOD usage history, broadcasting viewing history, search history, and recommendation result usage history are required.In order to increase the accuracy of usage pattern analysis, supply and demand in various ways If the transmitted contents are the same series / movie / broadcast, there is a need for a method for detecting them, a technology for automatically extracting the relationship between the contents and the series is needed, and the related metadata for each content / series is integrated. It is necessary to manage.

When a VOD provider receives a video content and services it on various screens, the content is matched by encoding the content in an optimized manner for each screen and giving the same unique identifier so that these files are generated from the same source. And content group management belonging to the same series, but when the same content is received through various supply and demand paths for each service platform, it is difficult to extract the relationship between the contents and the VOD service has already been provided for each service platform. Integration is not easy Therefore, there is a need for a technology capable of assigning a unique identifier by automatically mapping a relationship between various VOD contents and a VOD content and a real-time channel broadcasting program, and managing metadata in a standardized manner based on the identifier.

In addition, in order to provide content / series-related information that customers may be interested in according to the organization of VOD contents on 3Screen dynamically, new data / series information is extracted to obtain data that changes in real time and integrated metadata DB Real-time linkage with recommendation / search server and server providing UI / UX environment is essential.

Hereinafter, with reference to the accompanying drawings will be described in detail VOD content and broadcast program mapping method and apparatus according to the present invention.

1 is a view showing the configuration of an example of the VOD content and broadcast program mapping apparatus according to the present invention.

Referring to FIG. 1, the VOD content and broadcast program mapping apparatus includes a metadata collector 100, a genre sorter 110, a mapping data extractor 120, a mapper 130, a genre mapping table 140, and the like. An integrated metadata table 150 is included.

The metadata collector 100 collects metadata about VOD content or metadata about a real time broadcast program. More specifically, the metadata collection unit 100 collects metadata on VOD content from a content management system (CMS) that VOD service providers manage to provide various information to users when providing VOD services. Collect or collect metadata about the real-time broadcast program from the EPG-related information received from the real-time broadcast information provider. The metadata collector 100 will be described in detail with reference to FIG. 2.

The genre sorter 110 normalizes each genre of the VOD content and the broadcast program included in the metadata for the VOD content and the broadcast program through the genre mapping table 140. The genre mapping table 140 is a database that extracts all genre expressions from genre systems defined by each VOD service platform and real-time broadcast information provider, sets mapping relationships between genres, and stores standardized genre expressions.

The mapping data extracting unit 120 extracts a series number or a turn number from metadata of the VOD content and metadata of a broadcast program for mapping, and extracts key expressions according to each genre. That is, the mapping data extracting unit 120 defines various patterns expressing a series number or a series number, extracts the series number and the series number through a text mining process based on the defined pattern, and defines a terminology database for each genre. Extract key terms by genre for VOD content and real-time broadcast program using. The genre sorting unit 110 and the mapping data extracting unit 120 will be described in detail with reference to FIG. 4.

The mapping unit 130 performs mapping between the content and the broadcasting program based on the series number or the turn number extracted from the mapping data extracting unit 120 and the core expression, and stores the mapping number 130 together with the unique identification number in the integrated metadata data table 150. . That is, when the similarity between the metadata of the VOD content and the real-time broadcasting program is equal to or greater than a predetermined threshold, the mapping unit 130 determines whether the same series or the sequel is based on the series number or the turn number, If the similarity of metadata is greater than or equal to a certain threshold, the same content is identified. This gives the same unique identification number for the same content and can determine the relationship to the series. The mapping unit 130 will be described in detail with reference to FIGS. 5 and 6.

In addition, in order to respond to changes in content organization such as VOD content or real-time broadcast program, the metadata collector 100 periodically receives metadata about VOD content or real-time program and stores mapping relations between previously constructed contents. The mapping process is performed when there is no identical to the metadata of the mapping table. A process of periodically collecting metadata will be described in detail with reference to FIG. 2.

2 is a diagram illustrating a detailed process of the metadata collector according to the present invention.

Referring to FIG. 2, the metadata collection unit is a content information DB, a series information DB, a series and content of a content management system (CMS) 200 which service providers manage to provide various information to users when providing a VOD service. The metadata for each content or series is collected through an inter-mapping DB table (210). Examples of collected metadata include content ID, series ID, title, genre, year of production, country of production, director (director), actor, show time, release date (date of broadcast), synopsis, and the like. The metadata collector stores the collected content / series metadata in the content / series metadata table 220.

In addition, the metadata collector is a program code, program type, broadcast date, broadcast time, broadcast length, program source, genre, After collecting metadata 240, such as party information and management grade, the metadata is stored in the broadcast program metadata table 250 based on the program code.

Based on the metadata stored in the content / series metadata table 220 and the broadcast program metadata table 250, the contents are mapped by identifying whether the content is the same content or a series relation through the configuration to be described below. The unique identification information is given and stored in the mapping table 260, and the unique identification information and the corresponding metadata are combined into one record and stored in the integrated metadata data table 270.

3 is a diagram illustrating an example of a configuration for detecting new metadata according to the present invention.

Referring to FIG. 3, the metadata collector periodically receives the VOD contents / series schedule 300 from each VOD platform, and removes the duplicates of program codes, content IDs, and series IDs included in the schedule, and lists them. (S310). In addition, when the metadata collection unit does not exist in comparison with the values stored in the existing mapping table 260 (350), it is determined that the new VOD content / series and the ID of the new VOD content / series to determine the new metadata table ( 360).

In addition, the metadata collector periodically receives the real-time channel programming information 320, removes and duplicates the program code, content ID, and series ID included in the programming information (S330), and the existing mapping table. If the corresponding value does not exist in comparison with the stored values (S350), it is determined as a new program and the new code value is stored in the new metadata table (S360).

And mapping between contents / series / program by comparing the information stored in the integrated metadata table 270 with the metadata stored in the new metadata table 360 or comparing the metadata stored in the new metadata table 360. Perform a relationship extraction.

4 is a diagram illustrating an example of a detailed process of a genre sorting unit and a mapping data extracting unit according to the present invention.

Referring to FIG. 4, the genre system defined by each VOD service platform and real-time broadcasting information provider is slightly different in its representation and management system in order to provide an optimized UI environment for service operation and customers by platform. Mapping is required. For example, 'cartoon' in real-time broadcasting information and 'animation' in IPTV VOD are determined to be the same genre, and a process of matching them with a unified expression is required.

To this end, the genre sorter 400 extracts all genre representations of the genre system defined by each VOD service platform and real-time broadcast information provider, and then generates a mapping operation and standardized genre representations between them in the genre mapping table 410. . In addition, the genre sorting unit may expose a new genre expression that does not exist in the existing genre mapping table in the new metadata table 360 so that the manager can map one of the existing genre expressions or define a new genre. To help.

When mapping between each program code and VOD series / content ID for contents, series, and new program stored in the new metadata table 360, a comparison operation is performed between contents / series / programs belonging to this genre. In case of failure, mapping work with content / series belonging to genre with high genre similarity is performed. After the mapping operation is performed, the integrated metadata is stored in the integrated metadata table, and the genre field is stored in the standard genre representation defined in the genre mapping table 410.

The mapping data extractor 420 extracts information necessary for mapping between content / series from the content title, the VOD menu information, and the like through the pattern analysis 430. The series season number 440 may be an important value for mapping in the series, and the content may be a key value such as a broadcast date and a turn number 460. That is, the mapping data extracting unit includes 'season', 'time', 'tue', 'edition', 'river', 'part', year expression, month expression, and day for the series number 440 and the turn number 460. After defining a pattern for the expression, the series number 440 and the turn number 460 are automatically extracted from the metadata through a text mining process. The remaining portion of the series title except the series number 440 and the series number pattern value becomes the series basic title 450. Since the content title often includes a broadcast date 470, relevant information is extracted and then converted into a standardized expression (eg, 2010-08-30).

In addition, the mapping data extraction unit extracts key expressions for each genre from metadata fields such as contents / series / program titles, organization menus, synopsis, etc. through dictionary construction (S490). Expressions important for each genre are constructed in advance by genre-specific glossary 480 and extracted when a matching expression comes out, and can be used as a key value for content / series / broadcasting program mapping. For example, in the case of a sports genre, information necessary for content / series mapping may be extracted through pre-construction of a sports item name, a professional name, a competition name, and a tee name.

5 is a diagram illustrating an example of a series mapping process among detailed processes of the mapping unit according to the present invention.

Referring to FIG. 5, a series mapping operation is performed prior to the content mapping operation. In order to understand the propensity for each customer, it is necessary to understand the preferences for a specific series. Therefore, the mapping between the series and broadcasting series for each VOD platform extracts the same series and the relationship between the series, and provides them to the application service platform that needs personalization.

Basically, in the case of real-time channel programming information, when a broadcast program is a broadcast series, it is delivered based on the series title, and additionally provides channel name, genre name, and cast information. Since different titles are often assigned to the same series by channel or VOD platform, there is a lot of error when matching with only the series title. In the case of terrestrial broadcasting, there are many cases of self-produced series, but in case of PP channels that broadcast through cable, satellite, and DMB, the producers of the series being aired are often terrestrial or overseas broadcasters. It is often the case that the broadcast was broadcasted on

Therefore, the mapping unit performs mapping between series using various metadata fields as well as channel name information on which the corresponding series (500, 502) is broadcasted (510). For example, based on the title of the series, the name of the director, the name of the performer, and the degree of match for each genre. As a result, when the average value of the similarity exceeds a certain threshold (520), it is determined that the two series are similar. The mapping unit checks whether the season numbers match for two series having similar properties (530), and if they match, determines that the two series are the same series (540). If the season numbers are incorrect, the mapping unit determines the sequel relationship (550). ). For example, 'Friend Season 3' and 'Friend 3' are considered to be the same series, and 'Friend Season 3' and 'Friend 4' are sequel relationships with incorrect season numbers.

6 is a view showing an example of the content mapping process of the detailed process of the mapping unit according to the present invention.

Referring to FIG. 6, when the contents 600 and 602 are lower contents of a specific series (610), the mapping unit compares the recurrence information, the airing date, and the like with the contents having the same series ID as the upper series in the mapping table. In operation 620, it is determined that the two contents match.

If the content (650,652) is not a series, the mapping unit determines that the two contents match when the average value of the similarity exceeds a certain threshold based on the content title, genre name, director name, actor name, etc. between the two contents (660,670). ).

The mapping unit newly assigns unique IDs to IDs for which mapping between series and mapping between contents is completed, and stores new unique ID information in the mapping table. Also, after searching the metadata corresponding to the ID value mapped to the unique ID in the new metadata table, it is integrated into one table record and stored in the integrated metadata table.

7 is a diagram illustrating an example of providing information to a service platform according to the present invention.

Referring to FIG. 7, in order to provide a personalized service, the service unit uses VOD usage history, real-time broadcast viewing history, search result usage history, and recommendation result usage history for each customer based on a unique ID value viewed by a customer through a mapping table. Analysis is possible. Relevant metadata needed in the usage log analysis process in order to provide personalized service in each service group can search the integrated metadata table by unique ID value to grasp the propensity of each customer.

The present invention can also be embodied as computer-readable codes on a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like. 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.
