## Background
TECHNICAL FIELD
Embodiments of the present invention relate to a method of capturing a scene on a television (TV) screen and sharing the captured scene with a social service using a second device.
RELATED ART
When a user, for example, a viewer has viewed a television (TV) program or content, an impressive or interesting part on the side of the user may be separately provided, thereby maximizing the utilization of content.
With a social service being more active, the desire of a user to capture a favorite scene on a TV screen and to share the captured scene at a social service is also increasing. The user does not simply consume content but also creates a message relevant to the content such as after-view comments. Also, the user may serve to create and provide information by posting the created message at the social service.
Korean Patent Laid-Open Publication No. 10-2011-0085829 and No. 10-2011-0052137 propose a method and apparatus for sharing content based on a social network.
A user may post a message including feelings or opinions about content having been viewed by the user, at a social service being used by the user. The message may be related to a predetermined portion of the content, for example, a predetermined clip of the content.
However, currently, a method of capturing a scene on a TV screen is very limited. Although the above method is applicable by taking a photo using a smartphone and the like, it may cause a copyright issue.

In the case of, for example, Facebook, values of a user object provided through a social graph API as profile information of the user acquired in response to the capture request may be expressed by Table 1 and Table 2. Such information may be variously employed for marketing. Additionally, it is possible to collect information about even comments related to embedded content or linked content among bulletins registered by the user.
Hereinafter, a capture related principal method will be described with reference to FIG. 7.
FIG. 7 illustrates an example of a content capture process according to an embodiment of the present invention. The content capture process may be performed by a content playback device, a terminal, a service server, a media server, a content server, and a social service server described above with reference to FIGS. 1 through 6.
In response to a request from a user viewing content through the content playback device for capturing the content in operation 701, the capture module 320 of the terminal transmits a playback information request signal (playInfoRequest) to the playback information interface 220 of the content playback device in operation 702. Here, the playback information request signal may include identification information of the user (userId) and time information (datetime) as expressed by Table 3.
The playback information interface 220 of the content playback device determines a broadcast type, for example, a VOD or broadcasting, of the content being currently played back based on the playback information request signal in operation 703. In the case of broadcasting, the playback information interface 220 transfers a program information request signal (programInfoRequest) to the EPG information module 210 in operation 704.
In operation 705, the EPG information module 210 of the content playback device transfers program information of the content being currently played back to the playback information interface 220 as a response to the program information request signal (programInfoResponse).
Accordingly, in operation 706, the playback information interface 220 of the content playback device may provide, to the capture module 320 of the terminal, a response to the playback information request signal (playInfoResponse) including program information of the corresponding content. Here, the response signal (playInfoResponse) may include identification information of the user (userId), content playback information (contentOrder, contentId, contentTitle, and channel), and time information (datetime).

Here, ‘playInfoResponse’ may describe information on a ‘contentOrder’ field in the case of using a picture in picture (PIP) form in which a plurality of contents is displayed on a single screen. The order may be based on a top end of a screen layout or a screen size. Also, ‘contentId’ follows a uniform resource identifier (URI) configuration (RFC4151).
When the capture module 320 of the terminal is accurately aware of program information of the content being currently played back through the content playback device, the aforementioned process including operations 701 through 706 may be omitted.
When a capture request signal (captureRequest) for the corresponding content is received from the capture module 320 of the terminal in operation 707, and in this instance, when identification information (contentId) of the corresponding content is absent in the capture request signal, the capture interface 440 of the service server may request an open API center of a content server for identification information (contentId) of the content using time information (datetime) and channel information (channel) included in the capture request signal (captureRequest) in operation 708. Here, the capture request signal (captureRequest) may include identification information of the user (userId), time information (datetime), and content information (contentInfo). Here, ‘userID’ may use an open authorization (Oauth) key, and ‘contentInfo’ may include values of contentId, contentTitle, providerId, and channelInfo in a structural form.
Accordingly, in response to a request signal to content identification information (contentIdRequest) received from the capture interface 440 of the service server in operation 709, the open API center of the content server may transmit, as a respond (contentIdResponse), identification information of the content being currently played back at the content playback device of the user in operation 710.
In operation 711, the capture interface 440 of the service server transfers, to the capture display API 510 of the media server, the capture request signal (captureRequest) including identification information (contentId) of the corresponding content. In response thereto, in operation 712, the media server captures an image or a video of the content through a content capture engine and transfers a response signal (captureResponse) to the capture request signal to the service server through the capture display API 510. Here, in operation 713, the capture interface 440 of the service server transmits the capture response signal (captureResponse) to the terminal of the user. As expressed by Table 3, the capture response signal (captureResponse) may include identification information of the user (userId), content playback information (contentId and contentTitle), and capture request response information (captureRequest and captureRequestCode). Here, a ‘captureRequest’ value indicates a true or false value regarding whether the capture request is normally performed, and a ‘captureRequestCode’ value may define an error code (which may be arranged as a value, such as 0-O.K, 1-DRM not Free, and 2-Server Error).
FIG. 8 illustrates an example of the overall operation process of a capture service according to an embodiment of the present invention. The capture service method may be performed by a terminal, a service server, a media server, and a social service server described above with reference to FIGS. 1 through 6.
In operations 801 through 803, the terminal goes through a user authorization by executing an application associated with a capture service and inputs an agreement of a user relating to sharing user information for the capture service. Here, the user authorization may indicate an application-self authorization or an authorization through interaction with a social service being used by the user.
When the agreement relating to sharing information is transferred from the terminal of the user, the service server performs an authorization procedure on user information through interaction with the social service server in operation 804. Here, in operation 805, the social service server may verify a right associated with the corresponding user information to authorize the user information in response to the request of the service server.
