FIG. 1 is a diagram illustrating a configuration of a media cloud system capable of generating user content by recording and re-broadcasting broadcast content according to an embodiment of the present invention.

Referring to FIG. 1, a media cloud system includes a broadcaster system 110, a media cloud server 120, and at least one client device 130.

The broadcaster system 110 is a means for converting real-time broadcast contents into a predetermined codec format and transmitting them. A method of transmitting broadcast content in the broadcaster system 110 will be obvious to those skilled in the art and will not be described in further detail.

The media cloud server 120 is a means for accessing the broadcaster system 110 to acquire broadcast content, and to divide the broadcast content according to a predetermined method and store the divided content. In this manner, the media cloud server 120 separately stores and manages the broadcast program information in order to access the broadcast company system 110 to acquire and store the broadcast content.

For example, the media cloud server 120 may receive a specific broadcast content recording request from the client device 130. The media cloud server 120 may access the broadcasting system 110 for broadcasting the broadcast content requested to be recorded using the broadcast program information stored in the media cloud server 120, and may acquire and store the broadcast content. At this time, the media cloud server 120 may divide the broadcast content according to a predetermined method, and generate the divided content as a divided content, respectively, and store the divided content in a storage path according to a predetermined method.

In addition, the media cloud server 120 may generate the user content using the broadcast content recorded and stored according to a request of the client device 130, and may transmit the generated user content to the client device 130.

For example, the media cloud server 120 searches the additional data for the divided content according to the request of the client device 130, extracts at least one divided content suitable for the request, synthesizes the divided content, To the client device (130). At this time, the media cloud server 120 may transmit the corresponding user content to the client device 130 in a downloading or streaming manner.

In addition, the media cloud server 120 may store at least one of broadcast contents, divided contents, and user contents in a cloud storage space, and may continuously provide contents to allow N screen services among a plurality of client devices held by the user have. To this end, the media cloud server 120 may separately store and manage the content playback history for each client device 130. [

The client device 130 requests recording of the broadcast content to the media cloud server 120 and then receives and reproduces the recorded broadcast content or the re-processed user content according to the user's request using the recorded broadcast content to the media cloud server 120 ) To reproduce and reproduce data.

For example, the client device 130 may be an electronic device equipped with a wired / wireless communication module such as a TV, a set-top box, a mobile communication terminal, a notepad, a PDA, a tablet PC,

2 is a view showing a system for recording broadcast contents in general.

As shown in FIG. 2, a general broadcast content recording system includes a head end 210, a broadcast receiving apparatus 220, and a client device 130.

The headend 210 is means for providing real-time or on-demand broadcast content in accordance with broadcast programming information.

The broadcast receiving apparatus 220 is connected to the head end 210 to receive real-time or on-demand broadcast content.

Accordingly, in order for the client device 230 to record the specific broadcast content, the recording information including the recording time and the broadcast content information to be recorded may be registered through the broadcast receiving apparatus 220 connected to the client device 230, It is necessary to input the recording information on the broadcast receiving apparatus 220 through the controller operation.

Accordingly, the broadcast receiving apparatus 220 connects to the head end 210, records the broadcast content according to the recording information, and stores the broadcast content in the storage space in the broadcast receiving apparatus 220. Accordingly, when the client device 230 accesses the corresponding broadcast receiving apparatus 220, the client device 230 can reproduce only the recorded broadcast content.

Such a conventional recording method stores a recorded content in a storage space of the broadcast receiving apparatus 220 so that a user can actually access the recorded broadcast content except where the broadcast receiving apparatus 220 is located It did not exist.

Accordingly, as shown in FIG. 1, the broadcast content is recorded using broadcast programming information and then stored in the media cloud server 120, which is a cloud storage space, so that the user can enjoy the broadcast content requested by him / .

In addition, by storing the broadcast content recorded in the media cloud server 120 in the cloud storage space, the user has an advantage in that the user can reproduce the broadcast content recorded seamlessly through the connection between the plurality of client devices.

1 and 2, a method of recording and reproducing broadcast content through the media cloud server 120 according to an embodiment of the present invention is clearly understood from the difference from the prior art, Let us now focus on how to reprogram broadcast content to generate user content.

FIG. 3 is a diagram illustrating an internal structure of a media cloud server according to an exemplary embodiment of the present invention, and FIG. 4 is a diagram illustrating metadata for divided contents according to an exemplary embodiment of the present invention.

3, the media cloud server 120 according to an exemplary embodiment of the present invention includes a partitioning unit 310, a metadata management unit 315, a scenario management unit 320, a composing unit 325, 330, a memory 335, and a control unit 340.

The dividing unit 310 is a means for receiving and storing broadcast content using the broadcast program information stored in the memory 335, and dividing and storing the stored broadcast content according to a predetermined method.

For example, the division unit 310 may receive and store broadcasting contents transmitted from each broadcasting system 110 using broadcasting programming information. For example, the dividing unit 310 may receive and record only broadcasting contents according to the recording request received through the client device 130 through the broadcasting system 110. [

The division unit 310 may store the broadcast content transmitted through the broadcasting company system 110 and divide each broadcast content into a predetermined method. At this time, a method of dividing broadcasting contents can be various.

For example, the division unit 310 may divide the broadcast content into predetermined periodic units (e.g., hour, minute, second, etc.). For example, if the broadcast content is video content, the partitioning unit 310 may divide and store the content in units of frames.

In another example, the partitioning unit 310 may divide the broadcast content into a predetermined period, a sub-program unit, or a certain scene unit. The subprogram may be a unit program or each episode unit included in the broadcast content (for example, each episode unit constituting the broadcast content when the broadcast content is in the Obin bus format). For example, suppose the broadcast content is a gag concert. A distinct unitary program, such as " four ", " courageous guys ", and the like included in a gag concert may be sub-programs. In addition, it is needless to say that the divided unit 310 can divide the broadcast content by various methods.

In addition, the division unit 310 may generate and store a storage path according to a method specified for the divided broadcast contents (hereinafter, referred to as divided contents to facilitate understanding and explanation).

For example, the partitioning unit 310 may generate a storage path using at least one of the broadcast channel information, the broadcast date / time information, and the partitioning method, and then store each divided content.

For example, the partitioning unit 310 may generate a storage path as follows.

/ [Raw file folder] / [Broadcast channel identification information] / [Date and time information] / [

For example, suppose that a specific broadcast content of an EPG channel of Jan. 23, 2012 is recorded. The partitioning unit 310 may generate a storage path of the divided contents as follows.

/ RAW / EPG / 20120123/000000 / * 00:00 00:00 to 00:00 01:01 Video * /

/ RAW / EPG / 20120123/000001 / * Video from 00:00 01:00 to 00:00 02:02 * /

/ RAW / EPG / 20120123/000002 / * 00:00:00 02:00 ~ 00:00 03:02 Video * /

In addition, the division unit 310 may acquire and store meta data including a description of broadcast content through a broadcasting company system at the time of acquiring the broadcast content.

The metadata management unit 315 is a means for registering and managing respective pieces of metadata for each of the divided contents of the broadcast contents and the broadcast contents.

Here, the metadata for the divided content may be a description for describing the divided content. For example, the metadata for the divided contents may include at least one of channel information broadcasted by a broadcast content, program name, broadcast time by scene, performer by scene, plot by scene, keyword, weather, One can be included. It is needless to say that the metadata may further include various information for describing the divided contents. In addition, the keyword may be extracted from information included in the metadata (e.g., channel information, program name, broadcast time, cast, plot, etc.). The metadata for the split content is shown in Fig.

The scenario management unit 320 is a means for storing and managing user scenarios. Here, the user scenario may include a keyword that can retrieve metadata including at least one of performer, plot, place, and time.

For example, the client device 130 may send a content creation request, including a user scenario, to the media cloud server 120. Accordingly, if a user scenario is included in the content creation request, the scenario management unit 320 may extract and store the user scenario in the request.

In another example, the scenario management unit 320 may receive input in a designated format separately from the content generation request of the client device 130. [ In this case, the scenario management unit 320 may display a separate user interface for receiving user scenarios in a specified format, and receive and store user scenarios through the corresponding user interfaces.

The composing unit 325 is means for generating the user content using at least one divided content stored in response to receiving the content creation request from the client device 130. [

For example, the synthesizing unit 325 may extract a user scenario included in the content creation request upon receipt of the content creation request, and extract at least one keyword by analyzing the user scenario. Then, the composing unit 325 retrieves at least one keyword extracted from the user scenario, extracts at least one divided content corresponding to the matching metadata, synthesizes the extracted divided contents, Content can be generated. At this time, the combining unit 325 may search for and match the keywords and the metadata, and extract and combine at least one divided content corresponding to the metadata having the highest degree of matching. Here, the degree of matching indicates a matching ratio between the matched keyword and the meta data. For example, if there are three keywords and the first meta data matches two, the matching degree may be 67%.

The user scenario may include scenario-specific scenario information. In this case, the synthesizing unit 325 extracts at least one keyword from the scenario information for each scene, and searches for at least one meta data having the highest degree of matching through the matching search with the metadata, Can be extracted.

In such a case, the composing unit 325 may generate the user content by arranging the extracted divided contents according to the user scenario and synthesizing them. That is, the divided contents extracted in the order of each scene included in the user scenario can be synthesized to generate user contents.

In this specification, in order to facilitate understanding and explanation, the divisional contents are extracted and combined through matching of keywords and meta data. In addition, the divisional contents are extracted and synthesized through a user scenario and metadata matching It is possible.

Content provider 330 is a means for providing user content to client device 130. [

For example, the content provisioner 330 may provide the user content to the client device 110 in a downloading or streaming manner. The method of providing the content to the client device 110 through the downloading or streaming method itself is a known technique, and thus a separate description thereof will be omitted.

In addition, since the contents provider 330 stores the user contents in the cloud storage medium, when there are a plurality of client devices 110 used by the user, Lt; / RTI > for playback). In order to provide the N screen service, the content providing unit 330 may separately store and manage the playback history of the user content. The playback history is a log related to playback of the user content. The playback history may store information about a point at which the user content is reproduced. Even if the user changes the client device 110 to request playback of the user content, The content can be reproduced by connecting from the point where the reproduction has been completed to the device.

Such a user content may be shared through a client device owned by another user in addition to the N screen service between a plurality of client devices owned by the user. At this time, the content providing unit 330 may generate a content list based on the user content generated by the user, and may provide the generated content list to the client device owned by another user. In such a case, it is needless to say that the user content may be set separately as a user or a user group to be shared as attribute information.

The memory 335 stores broadcast program information, recorded broadcast contents, divided contents for each broadcast content, and metadata.

The control unit 340 may include internal components (e.g., an encoder 210, a segmentation unit 310, a metadata management unit 315, a scenario management unit (not shown) of the content generation apparatus 120 according to an exemplary embodiment of the present invention 320, a composing unit 325, a content providing unit 330, a memory 335, and the like).

In addition, the control unit 340 can receive and record the broadcasting contents according to the user's recording request through the broadcasting company system 110. FIG. Of course, the control unit 340 may record and record the broadcast contents transmitted through the broadcasting system 110 using the broadcast programming information, respectively.

5 is a flowchart illustrating a method of storing broadcast content in a media cloud server according to an embodiment of the present invention. Each of the steps described below is performed by each internal component of the media cloud server, but will be collectively referred to as a media cloud server in order to facilitate understanding and explanation.

In step 510, the media cloud server 120 records broadcast content transmitted from each broadcasting system 110 using broadcast programming information and stores the broadcast content.

Of course, according to the implementation method, the media cloud server 120 can access only the broadcast contents according to the recording request of each client device 130 by connecting to the broadcasting company system 110, and record it.

In step 515, the media cloud server 120 divides the recorded broadcast content according to a predetermined method, and stores the divided content as divided contents.

3, the media cloud server 120 generates a storage path for storing the divided contents using at least one of the metadata and the division method for the broadcast contents, and then stores the divided contents in the corresponding storage path Respectively.

In FIG. 5, the media cloud server 120 can store the metadata of the broadcast content using the broadcast schedule information, although it is not mentioned in the process of separately storing the metadata according to the broadcast content. Of course, it is natural that, according to the implementation method, it is possible to further receive the metadata about the broadcast content through the broadcasting company system 110 at the time of receiving the broadcast content.

In step 520, the media cloud server 120 registers and stores metadata for each divided content. Here, the meta data for each divided content may include at least one of broadcast channel information, performers for each scene, storyline for each scene, scene for each scene, and broadcast time, as described above.

5, it should be understood that broadcast contents, divided contents, user contents, and the like are stored in the cloud storage space.

6 is a flowchart illustrating a method of generating a user content using broadcast content according to an exemplary embodiment of the present invention. Hereinafter, it is assumed that at least one broadcast content is recorded and stored and then stored as a divided content according to a designated method, and the metadata for each divided content is stored. .

At step 610, the client device 130 sends a content creation request to the media cloud server 120. Here, the content creation request may include a user scenario. Of course, depending on the implementation method, the content creation request may also include a user scenario. That is, the client device 130 may separately transmit the user scenario to the media cloud server 120 before or after the content generation request.

For example, the client device 130 may be provided with a separate user interface for receiving a user scenario from the media cloud server 120 before or after a content creation request, and may input a user scenario through the corresponding user interface You may.

Also, the user scenario may include scenario information for each scene, or the entire scenario may be described without a scene.

Hereinafter, the following description will be made on the assumption that the user scenario is included in the content creation request transmitted from the client device 130. [

As described above, the user scenario may include at least one of a plot, a place, a time, and a performer so that metadata search for each divided content is possible.

In step 615, the media cloud server 120 extracts user scenarios included in the content generation request received from the client device 130, analyzes the metadata, and searches metadata corresponding to the respective divided data, One divided content is extracted.

For example, the user scenario includes at least one of a plot, a place, a time, and a performer, as described above, and may be information included in each metadata of the divided data. Then, the media cloud server 120 extracts a meaningful keyword from the user scenario through morphological analysis, and then extracts the divided content having the highest degree of matching through the matching search between the metadata of each divided data and the extracted keywords have.

Of course, when there are a plurality of keywords extracted from the user scenario, the content generation apparatus 120 searches the user scenario for the extracted keyword and the additional data, and then matches the additional data with the highest degree of matching (highest matching ratio) The contents can be extracted in the order of the divided contents.

In operation 620, the media cloud server 120 generates the user content by combining the extracted at least one divided content. At this time, the media cloud server 120 may generate the user contents by synthesizing the extracted divided contents in the order included in the user scenario. The user contents thus stored are stored in the cloud storage space.

In step 625, the media cloud server 120 receives a user content provision request from the client device 130. [

Accordingly, in step 630, the media cloud server 120 transmits the user content according to the request to the client device 130 in a downloading or streaming manner.

The media cloud server 120 may store the playback history for each user content. Here, the reproduction history may include the reproduction end point.

Accordingly, the media cloud server 120 can provide seamless streaming service of user contents between a plurality of client devices owned by the user.

Meanwhile, a method of generating user content suitable for a user scenario using broadcast contents according to an embodiment of the present invention may be implemented in the form of a program command that can be executed through a variety of means for processing information electronically, .
