4 is a flowchart illustrating a method for producing and sharing a video clip using metadata according to an embodiment of the present invention, which is applied to the apparatus of FIGS. 1-3 and will be described in parallel with the operation of the apparatus.

First, the video providing unit 210 of the video server 200 transmits the first video content (the original video or the video of a specific part) through the wired / wireless communication network 100 according to communication with the user terminal 300. Provided in (S401).

Next, the user terminal 300 receives the first video content through the video receiving unit 370, selects a specific part of the received first video according to user selection through the video selecting unit 310, and metadata The generation unit 330 generates metadata UCB for the video of the selected specific portion (hereinafter referred to as second video content) (S403). For example, the second video content may be selected from the total amount of the first video content (ie, the original video) as shown in FIG. 5.

The start time and the end time of a specific part may correspond to the video (A) of a specific part clipped (or referred to as a bookmark). In this case, metadata about the second video content is generated according to the format of Table 1, Third field (desc) for the bookmark purpose or classification information of the second video content, the fourth time for the start time information and the end time information of the second video content that is the video (A) of a specific part of the first video that is the original video Field (start_time) and fifth field (end_time), the sixth field (open_flag) for sharing information on the second video content, and the eighth field (open_name) for creator information on the second video content, respectively. It can be generated by selectively recording the data of the information. That is, as an example of the metadata (UCB) format for the second video content according to the present embodiment, as shown in FIG. 6, ID information (corresponding to data in the second field) of the original video and the original video are shown. Bookmark information including the start time information (corresponding to the data in the fourth field) and the end time information (corresponding to the data in the fifth field) in the original video. Or bookmark description information including information on the classification information (corresponding to the data in the third field), sharing information (corresponding to the data in the sixth field), preference information (corresponding to the data in the seventh field), and UCB. And additional information of the bookmark including sharing information having the producer name information (corresponding to the data of the eighth field).

When clipping or bookmarking a specific portion of a video, the original video ID, start time, and end time may be included. UCB (User Created Bookmark) with additional information added to these bookmarks can be created and applied to education or entertainment. As illustrated in FIG. 6, the additional information may include shared information such as a bookmark reason, a description of a bookmark such as classification information, an indication of whether to share it, a user's preference, and a producer's name.

For example, a video clip of 10-12 minutes from the start of the news, which is a press time for a total eclipse, was broadcasted on July 22, 2009 by an elementary school teacher to explain the total eclipse during the fifth grade science class. , The original video of the bookmark (data in the second field) is' TV news', the start time (data in the fourth field) is '10 minutes' and the end time (data in the fifth field) is' 12 '. Minutes. If the teacher creates a UCB, in addition to the basic bookmark information, the UCB description or classification information (data in the third field) is known as' Grade 5 / 2nd Semester / Science / 07. The Family of the Sun / [1st Time] View ', sharing status (data in the sixth field) is' allow sharing', UCB author (data in the eighth field) is' teacher name '. UCBs are classified and managed according to the classification information so that users with the same interests can easily select and use UCBs created by other users. If other teachers use and recommend the shared UCB, it is reflected in the preference information (data in the seventh field) so that other teachers can easily select and use the highly preferred UCB by referring to this preference information.

Another example of an entertainment application is that when servicing a TV program, viewers can produce scenes that the performer makes a mistake in the UCB with bookmark classification information (the third field of data) called 'Star NG Scenes', or It is also possible to make the kiss scenes as UCBs with bookmark classification information (the data in the third field) called 'Kiss scene' so that they can be easily shared, modified and evaluated while watching.

In the present embodiment, the selection of the specific portion A through the video selection unit 310 is an example of the specific portion A to be bookmarked using a video editing tool as shown in FIG. 7. The start point and the end point of the corresponding section may be grasped and dragged, and corresponding information of the fourth field start_time and the fifth field end_time may be generated by the metadata generator 330. In addition, as shown in FIG. 7, when a corresponding part is selected from a category list for classification displayed in a pop-up window, the metadata generating unit 330 generates corresponding classification information of the third field. In addition, when a user selects a sharing check box portion in the pop-up window as shown in FIG. 7, the metadata generating unit 330 generates corresponding sharing information of the sixth field. In the present embodiment, when the shared information of the sixth field is shared 'Yes' and 'None', the corresponding metadata UCB is transmitted to the server 200 to make a database, but the shared information is YES. If the corresponding metadata (UCB) is shared and made available to the user as well as other users, and shared 'no', for example, other users cannot use it and only the user can log in with their own ID. Can be.

Subsequently, the metadata transmitter 350 of the user terminal 300 transmits the metadata generated by the metadata generator 330 to the video server 200 (S405).

Next, the metadata storage unit 230 of the video server 200 receives and stores the metadata transmitted from the user terminal 300 (S407).

Next, the video receiving unit 370 of the user terminal 300 receives the second video content as a video of a specific part from the video server 200 in association with the metadata of the constructed database (S413) and the corresponding metadata (UCB). Second video content) is used (S415).

Finally, the user evaluates the second video content of the metadata UCB (S417), and generates recommendation information for recommending the second video content to others through the metadata generator 330, or The same process as in step S403 is performed on the second video content to generate the modified metadata for the third video content (for example, a specific portion of the second video content), and the generated recommendation information or the modified metadata. The transmission is transmitted to the video server 200 through the metadata transmission unit 350 (S419). For example, the recommendation information according to the present embodiment may be generated by selecting a thumb-up button for video content of a specific metadata UCB from the UCB list displayed on the screen as illustrated in FIG. 8. .

In addition, the metadata storage unit 230 of the video server 200 stores the received recommendation information or the correction metadata, and the database builder 250 receives the received information at step S405 based on the recommendation information or the correction metadata. After modifying or selecting the metadata (S409), a database for the owned video is constructed based on the modified and / or selected metadata (S411).
