Description

Technical Field [0001] The present invention relates to a video content providing server,

The present invention relates to a video content providing server and a method for providing video content, and more particularly, to a video content providing server and a method of providing video content, And a method of providing a video content providing server.

Due to the development of video technology and communication technology, various video contents are produced and distributed through a communication network such as the Internet. User-generated content (UGC) produced by general users and Professionally Generated Content (PGC) produced by experts such as TV programs, commercials, movies, and music videos can be distinguished according to the producers of video contents. PGC has higher quality than UGC because it is created by professional editing of various video sources generated by professional shooting. In recent years, however, due to the development of imaging equipment and the development of editing equipments, there is a need to produce UGC of higher quality since the UGC of the quality close to PGC is generated by the general user.

Meanwhile, a method of enhancing the quality of video contents is a method of photographing the same event or subject through a plurality of camera devices and editing the same. For example, in order to generate video contents of three minutes in length, the first camera photographs the face of the subject in close-up, the second camera photographs the upper half of the subject, and the third camera photographs the whole body of the subject. In the editing, the face image of the first camera is used for the first minute, the upper half body image of the second camera is used for the next minute, and the whole body image of the third camera is used for the next minute . This multi-camera image editing can enhance the image quality by giving a liveliness to the monotonous video contents.

US Patent Publication No. 2004-0179816 to Sony Corporation, entitled " Picture Material Editing Apparatus and Picture Material Editing Method " and US Patent No. 6,353,461 to Panavision, Inc., entitled " Multiple Camera Video Assist Control System " An editing apparatus for editing a plurality of camera video data to generate video contents is disclosed. Such editing devices provide the effect of producing high quality video content through non-linear editing of camera video data generated from multiple camera devices. However, the camera video data generated from a plurality of cameras is provided only to a video editing specialist, and when a specific camera viewpoint is selected for video contents, there is a problem that a scene at another camera viewpoint can not be viewed afterwards. For example, when the edited video content is uploaded to the video content providing service, the user accesses the corresponding service through the communication network and receives the edited video content continuously. Due to this characteristic, the user who watched the video contents is not motivated to watch the same video contents again, and even if he / she views the video content again, he / she feels a tired feeling.

U.S. Patent No. 8,249,153 to In Extenso Holdings, Inc., entitled " Distributed Synchronized Video Viewing and Editing ", transmits a plurality of camera video data shot by a plurality of cameras to a editing user via a communication network in a single composite stream, ≪ / RTI > FIG. 1 shows a system for producing video content through an editing operation selecting a plurality of camera video data. According to this, since the editing user receives all the camera video data shot by the plurality of cameras through the communication network as a synthesized video stream, the editing user at the remote site can review all camera video data and perform video editing. However, even in such a system, a user who consumes video content that has been subjected to video editing has a problem of continuously watching only the fixed camera video data selected by the editing user.

In order to overcome the inevitability of such video contents, it is necessary to add subtitles or advertisements to the video contents later or to add an interactive object for guiding to a specific web page, so that the reproduced video contents . ≪ / RTI > However, this method can not change the image itself, which is the most prominent part of the video contents, and thus it does not provide sufficient motivation to attract the viewer to view it again.

US Patent Publication No. 2016-0105707 entitled " Systems and Methods for Delivering Secondary Content to Viewers " of DISNEY ENTERPRISES, INC. Discloses a system for providing a secondary product including an audio track of an originally generated video content and a different audio track do. According to such a system, since the original video contents and the reproduced video contents are provided, there is an advantage that the user can continuously attract attention. However, this is limited to the change of the audio track and can not provide the change of the video itself which is the most prominent part of the video contents.

Another method is to simultaneously provide a plurality of camera views to a user in video contents photographed by a multi-camera device or change the camera viewpoint according to a user's selection. This method has the advantage that the user can enjoy video contents at various camera viewpoints.

US Patent No. 7,196, 722 to iMove, Inc., which is incorporated herein by reference in its entirety, provides a high-resolution image of a selected camera among multiple camera video data generated by a plurality of cameras, As a thumbnail image. According to such a system, the user of the video contents can enjoy the video contents by selecting a desired camera view. However, since users of general video contents commonly use video contents passively, there is a disadvantage that they are rather inconvenienced in positively selecting a camera view.

FIG. 1 illustrates a video content providing server 200 according to an embodiment of the present invention. The video content providing server 200 according to the present invention includes a camera video data storage module 210, a video content production module 220, a video content storage module 230, a video content reproduction module 240, 250).

The camera video data storage module 210 performs a function of simultaneously recording the first camera video data (data_video_cam_1) to nth camera video data (data_video_cam_n) (n is an integer of 2 or more) do. The camera video data storage module 210 may be configured as a conventional data storage device, and may be an optical storage device, a magnetic storage device, or a semiconductor storage device. The camera video data storage module 210 stores camera video data received from the multiple camera device 100 and the multiple camera device 100 is configured to capture the same event in various camera views. For example, the first camera device 101 may photograph a close-up face of a performer, the second camera device 102 may photograph an upper body of a performer, and the third camera device 103 may be configured to photograph a body of a performer have. In some embodiments, all or part of the multiple camera apparatus 100 may be configured to be capable of camera movement control, pan control, tilt control, and zoom control to generate a dynamic image Do. The multiple camera apparatuses 100 are configured to photograph the same event. At this time, not all of the multiple camera apparatuses 100 need to photograph the same subject. For example, when shooting the performance of a singer, the first camera apparatus 101 and the second camera apparatus 102 photograph the singer, (103) can be configured to shoot a crowd or performer.

The first camera video data (data_video_cam_1) to the nth camera video data (data_video_cam_n) may store the data generated by the multiple camera apparatus 100 as they are, and the data subjected to the image conversion processing may be stored. For example, video data that has undergone correction processing to equalize images of each camera, data compression processing to reduce data storage amount, or image processing to remove unnecessary portions from the image may be stored in the camera video data storage module 210 .

The video content production module 220 generates edited video data (data_video_edit) based on the first camera video data (data_video_cam_1) to the nth camera video data (data_video_cam_n). At this time, the edit video data (data_video_edit) selects any one of the first camera video data (data_video_cam_1) to the nth camera video data (data_video_cam_n) in the first variable interval constituted by some sections of the playback section as the first selected camera video data data_video_cam_select_1). Edit video data (data_video_edit) is a content that has undergone video editing process and is generated by editing by an automated editing or editing expert. Automated editing may be performed in a manner that prior specifies camera video data to be used in video content, or may be performed through known methods such as image analysis, speech analysis, or machine learning. The edit video data (data_video_edit) itself may be in the form of a multimedia file including video information, but according to an embodiment, an EDL (edit) data composed of source data used for editing and a markup file designating an editing effect Decision List) file.

The video editing is performed by a method of selecting camera video data to be used for each time interval of the edited video data (data_video_edit). Fig. 2 shows an example of edit video data (data_video_edit). For example, the first camera video data (data_video_cam_1,401) is video data of the face of the performer, the second camera video data (data_video_cam_2,402) is video data of the upper part of the performer and the third camera video data (data_video_cam_3 , ≪ / RTI > 403) are video data of the entire body of the performer. When the 3-minute video is created through video editing, the first camera video data (data_video_cam_1,401) is selected in the first section from 0 minutes to 1 minute, and the first camera video data (data_video_cam_1,401) is selected in the second section from 1 minute to 2 minutes 2 camera video data (data_video_cam_2,402), and the third camera video data (data_video_cam_3,403) is selected in the third section from 2 minutes to 3 minutes to generate edited video data (data_video_edit, 410) have. In this case, the first variable section 411 is from 0 minute to 1 minute in the first section, and the first selected camera video data (data_video_cam_select_1) is the first camera video data (data_video_cam_1,401).

The variable section is a section that can change from reedited video data (data_video_reedit) described later to camera video data not used in editing. In the embodiment of FIG. 2, the variable interval may be selected as a single edit video data (data_video_edit), for example, from 0 minute to 1 minute, and two edit video data (data_video_edit) , And one edit video data (data_video_edit) may be selected as a part of the selected section, for example, from 30 seconds to 1 minute. In order to improve the intention of video editing in selecting a variable section, it is necessary to set a variable section so as to reduce the rate of change of the reedited video contents and to increase the rate of change of the reedited video contents, Can be set larger.

The video content storage module 230 functions to store edited video data (data_video_edit). The video content storage module 230 may be configured as a conventional data storage device similar to the camera video data storage module 210, and may be an optical storage device, a magnetic storage device, or a semiconductor storage device. The video content storage module 230 may be physically separated from the camera video data storage module 210 or may be configured as a single device.

The video content reproduction module 240 performs a function of generating reedited video data data_video_reedit in response to a reediting request (request_reedit) for the edited video data (data_video_edit) received through the communication network from the user terminal 300 . At this time, the reedited video data (data_video_reedit) is the first selected camera video data (data_video_cam_select_1) among the first camera video data (data_video_cam_1) to nth camera video data (data_video_cam_n) in the first variable section of the edited video data And includes any one of them as the first reselected camera video data (data_video_cam_reselect_1) at random or according to a predefined rule.

The user terminal 300 refers to a user terminal 300 connected to a web page on which a web service is provided by a web service module 250 described later through a communication network. The user terminal 300 is not particularly limited and may be an information terminal such as a PC, a smart phone, or a tablet PC, which can access a web page through a communication network such as the Internet or an intranet. The user terminal 300 receives the edited video data (data_video_edit) stored in the video content storage module 230 through the web service module 250 and transmits the edit video data (data_video_edit) to the video content providing server 200 through the re- And requests re-editing of the video data (data_video_edit). The request for re-editing (request_reedit) can be implemented in various ways. For example, when the user edits the corresponding edited video data (data_video_edit) on the video viewer screen 500 on the user terminal 300 as shown in FIG. When the "re-edit" icon 502 is selected, the user terminal 300 can be implemented as a method of transmitting a re-edit request (request_reedit) to the video content providing server 200 through the communication network. The user identified by the user terminal 300 or the user identifier receiving the edited video data data_video_edit again requests the video content providing server 200 to reproduce the same video content 501 through the communication network, The providing server 200 may recognize the request as a request for re-editing (request_reedit). Meanwhile, the video content reproduction module 240 generates the reedited video data (data_video_reedit) according to the request for re-editing (request_reedit) of the user terminal 300 or the user who made the content request for the edited video data (data_video_edit) . This allows the user who has not watched the edited video data (data_video_edit) to preferentially be provided with the reedited video data (data_video_reedit) by preferentially receiving the edited video data (data_video_edit) reflecting the editing intention to the user in the corresponding video contents .

The reedited video data (data_video_reedit) is generated by replacing the camera video data used in the first variable section of the edited video data (data_video_edit) with another camera video data. Selection of other camera video data may be performed by randomly selecting camera video data other than the first selected camera video data (data_video_cam_select_1) used in the first variable section according to a predefined rule or the first selected camera video data (data_video_cam_reselect_1) . The predefined rule is set to the first camera video data (data_video_cam_select_1) as the first camera video data (data_video_cam_1) and the second camera video data (data_video_cam_2) as the next camera video data adjacent thereto if the first selected camera video data data_video_cam_select) is the first camera video data (data_video_cam_1), and the third camera video data (data_video_cam_3), which is the next camera video data adjacent thereto, as the first selected camera video data (data_video_cam_select) data_video_cam_select) is the first camera video data (data_video_cam_1), the first camera video data (data_video_cam_1), which is the next camera video data adjacent to the first camera video data (data_video_cam_select) It may be a rule that includes a (data_video_cam_reselect_1). Or the rule that the editor selects the camera video data ranked in the order of the first variable section as the first reselected camera video data (data_video_cam_reselect_1). Alternatively, in the case of selecting the first reselected camera video data (data_video_cam_reselect_1) at random, a rule for minimizing the overlap between the camera video data selected in the preceding section or the following section and the first reselected camera video data (data_video_cam_reselect_1) May be added. The first reselection camera video data (data_video_cam_reselect_1) is automatically selected by a random or predetermined rule rather than by the editor, and may be implemented so that the same reedited video data (data_video_reedit) is provided to all users, Edited video data (data_video_reedit) may be provided. The reediting video data (data_video_reedit) itself may be in the form of multimedia files including video information such as AVI, WMV, MP4, FLV, ASF, MKV, MOV, etc. In some embodiments, Or an EDL (Decision List) file composed of a markup file specifying data and an editing effect. The reediting video data (data_video_reedit) may be stored in the video content storage module 230 according to an embodiment.

2, the video content reproduction module 240 generates the first camera video data (video_video_cam_select_1) selected by the first selected camera video data (data_video_cam_select_1) from 0 minute to 1 minute as the first variable section 421 the second camera video data (data_video_cam_2, 402) or the third camera video data (data_video_cam_3, 403) excluding the data_video_cam_1, data_video_cam_1 401 can be selected as the first reselection camera video data (data_video_cam_reselect_1) The third camera video data (data_video_cam_3, 403) which does not overlap with the second camera video data (data_video_cam_2, 402) in the following section is selected as the first reselected camera video data (data_video_cam_reselect_1) , 420 are generated.

The web service module 250 provides the edited video data (data_video_edit) and reedited video data (data_video_reedit) to the user terminal 300 through a communication network. The web service module 250 may be, for example, a web server providing a web page capable of providing a plurality of video contents, and may be provided by a method of providing a plurality of video content lists to a user, May be implemented to provide the user with specific video content. The web service module 250 provides the edited video data (data_video_edit) or the reedited video data (data_video_reedit) to the user terminal 300 in a streaming or downloading manner. Edited video data (data_video_edit) and re-edited video data (data_video_reedit) may be provided in the form of a moving picture file or may be transformed into a file of a suitable size in consideration of the communication environment or the system environment of the user terminal 300 and provided. If the edited video data (data_video_edit) and the reedited video data (data_video_reedit) are in the form of an EDL file, a moving picture file conforming to the EDL can be generated and provided to the user terminal 300.

According to such a configuration, the video content providing server 200 according to the present invention automatically generates re-edited video content modified from the original video content, thereby increasing the motivation to re-view the video content of the user and causing continuous interest.

On the other hand, it is desirable to re-edit the re-edited video contents according to the continuous viewing of the video contents. To this end, the video content reproduction module 240 performs a reediting process according to a reediting request (request_rereedit) for the reedited video data (data_video_reedit) received through the communication network from the user terminal 300 that has issued a reediting request (request_reedit) One of the first camera video data (data_video_cam_1) to the nth camera video data (data_video_cam_n) except for the first reselected camera video data (data_video_cam_reselect_1) is randomly or predefined in the first variable interval of the video data (data_video_reedit) Edited video data (data_video_rereedit) that has been edited so as to be included in the first re-selection camera video data (data_video_cam_rereselect_1) in accordance with the rule that the re-editing video data (data_video_rereedit) To the user terminal 300 via the Internet.
