[0146] Figure 5 is a flowchart illustrating an example method of operating a display device according to various embodiments.

[0147] refer to Figure 5 In operation 510, the display device 100 may display content. The display device 100 may receive content from various content providing sources and may display the content. For example, the display device 100 may retrieve and display content stored in an internal memory of the display device 100, may display content received from an external input device connected via a wired / wireless interface, or may display content received via the Internet or a broadcast network. The content displayed on the display device 100 may include various types of content. For example, the content may include various types of content such as moving image content, still image content, and game content.

[0148] In operation 520 , the display apparatus 100 may recognize that the displayed content is sharable content.

[0149] The display device 100 according to an embodiment of the present disclosure can identify whether the content is shareable content, so that the content can be shared with other adjacent devices according to the content sharing technology through the content sharing operation between the multiple content displayed on the display device 100. Whether the content is shareable content can be identified by checking whether the content is content free of copyright issues. Therefore, when identifying whether the content is shareable content, it can refer to, for example, identifying whether the content can be shared through content sharing technology. For content free of copyright issues, the display device 100 can perform shooting or sharing operations according to content sharing technology. However, for content that is not free of copyright issues, the display device 100 may not perform shooting or sharing operations according to content sharing technology. Content free of copyright issues may refer to content without copyright issues, such as content where the copyright itself does not exist, content where the copyright has expired, or content with limited copyright. Because the display device 100 according to an embodiment of the present disclosure enables content free of copyright issues to be shared with other devices according to the user's intention, the user can conveniently use the content.

[0150] According to an embodiment of the present disclosure, the display device 100 can identify that the displayed content is shareable content based on the attribute information of the displayed content. The display device 100 can obtain the attribute information of the content through metadata of the content, etc. The attribute information of the content may include at least one of the identification information of the content, the category of the content, or the copyright information of the content.

[0151] According to an embodiment of the present disclosure, the display device 100 may identify whether the content is sharable content, ie, content free from copyright issues, using at least one of identification information of the content, category of the content, or copyright information of the content.

[0152] According to an embodiment of the present disclosure, the display device 100 can identify that the content is shareable content by communicating with an external server that provides copyright information of multiple contents. For example, the display device 100 can use the identification information of the content displayed on the display device 100 for the copyright information of the content, obtain the copyright information of the content by querying the external server that provides copyright information of various contents, and receive the copyright information of the content in response to the query, and the display device 100 can identify that the content is shareable content based on the obtained copyright information.

[0153] According to an embodiment of the present disclosure, when the display device 100 is in the game mode automatically, the display device 100 can recognize that the displayed content is shareable content. For example, when the automatic low latency mode (ALLM) is recognized in the game mode, the display device 100 can recognize that the displayed content is shareable content. ALLM is one of the HDMI 2.1 standard specifications and relates to a technology for reducing the delay time between controller input and game content output. For example, a device such as a PC or a game console that supports HDMI 2.1 includes ALLM information in an HDMI infoframe, and the display device 100 can check the ALLM information from the HDMI infoframe received from the device such as a PC or a game console.

[0154] In operation 530 , the display apparatus 100 may broadcast a signal including state information indicating that the displayed content is sharable content.

[0155] The display device 100 may broadcast a signal including status information indicating that the content currently displayed on the display device 100 is a photographable content (i.e., a shareable content), so that a neighboring electronic device receiving the signal recognizes that content sharing can be requested. That is, when a signal including status information indicating that the content is shareable content is broadcast, an electronic device that wishes to share the content from among the electronic devices receiving the broadcast signal may send a content sharing request to the display device 100.

[0156] According to an embodiment of the present disclosure, the display device 100 may broadcast a signal including status information indicating that the displayed content is shareable content using any of various short-range communication technologies. For example, the display device 100 may broadcast a signal using any of various short-range communication technologies such as Wi-Fi communication technology, Bluetooth communication technology, or BLE communication technology.

[0157] In operation 540 , the display apparatus 100 may receive a content sharing request for sharing content based on the broadcast signal from the electronic device 200 .

[0158] When display device 100 broadcasts a signal including status information indicating that displayed content is shareable content using any of a variety of short-range communication technologies, an electronic device from one or more electronic devices receiving the broadcast signal that wishes to share content displayed on display device 100 may send a content sharing request to display device 100, and display device 100 may receive the content sharing request.

[0159] According to an embodiment of the present disclosure, the display apparatus 100 may use any of various communication technologies to receive a content sharing request from the electronic device 200. For example, the display apparatus 100 may use any of various short-range communication technologies such as Wi-Fi communication technology, Bluetooth communication technology, or BLE communication technology to receive a content sharing request from the electronic device.

[0160] According to an embodiment of the present disclosure, the display device 100 can receive a query from the electronic device 200 to identify whether the sender of the broadcast is the display device 100, can send a response signal indicating that the sender of the broadcast signal is the display device 100 to the electronic device 200 in response to the query of the electronic device 200, and can receive a content sharing request from the electronic device.

[0161] In operation 550 , the display apparatus 100 may transmit at least a portion of the content output to the display to the electronic device 200 in response to the content sharing request using a content sharing technology.

[0162] According to an embodiment of the present disclosure, the display apparatus 100 may transmit at least a portion of the content displayed on the display to the electronic device in response to a content sharing request of the electronic device, using any of various content sharing technologies.

[0163] According to an embodiment of the present disclosure, the display device 100 can use content sharing technology to send the entire content displayed on the display to the electronic device. In this case, when the content displayed on the display includes video content and graphic content (such as a user interface overlaid on the video content), the display device 100 can use content sharing technology to send both the video content and the graphic content. In this case, the graphic content sent in addition to the video content may be content that the user of the electronic device does not want.

[0164] According to an embodiment of the present disclosure, the display device 100 can use content sharing technology to send only some of the content displayed on the display (i.e., only the video content) to the electronic device. Because the user of the electronic device may want to use only the video content, the display device 100 can filter and send additional content such as a user interface other than the video content.

[0165] Figure 6 is a flowchart illustrating an example method of operating an electronic device to share content displayed on a display device according to various embodiments.

[0166] refer to Figure 6 , in operation 610, the electronic device 200 may obtain an image of a screen of the display device 100 displaying content through a camera.

[0167] For example, a user carrying the electronic device 200 may want to use the content displayed on the display device 100 for personal purposes while viewing the content through the display device 100. The user may want to capture or record a portion of the content displayed on the display device 100, and use the captured or recorded content for personal purposes. For example, the user may want to capture or record a portion of movie content displayed on the display device 100, and upload the captured or recorded portion of the content to a social networking service application or the like. In this case, the user can use the camera of the electronic device 200 to control shooting or previewing the screen of the display device 100.

[0168] In operation 620 , the electronic device 200 may receive a broadcast signal including state information indicating that content displayed on the display apparatus 100 is sharable content.

[0169] According to an embodiment of the present disclosure, the electronic device 200 may receive a broadcast signal from the display device 100 using any of a variety of short-range communication technologies, and may check status information indicating that the content displayed on the display device 100 is shareable content from the received broadcast signal. For example, the electronic device 200 may include a BLE communication module that may always receive a BLE signal, and such status information may be extracted from the received BLE signal through the BLE communication module.

[0170] In operation 630, the electronic device 200 may identify (eg, determine whether) a display device of an image obtained through a camera is a display device that transmits the broadcast signal using the broadcast signal.

[0171] In a space where a user enjoys content through the display device 100, there may be more display devices other than the display device 100, and other display devices may also display content. In various cases including this case, the electronic device 200 needs to identify whether the display device that sends the broadcast signal is the same as the display device that actually displays the content. Therefore, the electronic device 200 may perform an operation of checking whether the display device that sends the broadcast signal is the same as the display device that actually displays the content.

[0172] According to an embodiment of the present disclosure, the electronic device 200 may send a signal for requesting identification of whether the display device 100 is the device currently displaying content to the display device 100 that sends the broadcast signal, and when the display device 100 provides a response to the identification request signal, the electronic device 200 may check the response to identify whether the display device 100 is the device currently displaying content.

[0173] According to an embodiment of the present disclosure, the electronic device 200 may send a signal for requesting identification of whether the display device 100 is the device currently displaying the content to the display device 100 that transmits the broadcast, and the display device 100 may output predetermined (e.g., specified) response information to the display of the display device 100 in response to the identification request signal. The electronic device 200 may check whether the display device 100 is the device currently displaying the content by analyzing an image of the screen of the display device 100 obtained by a camera and extracting the response information from the image of the analyzed screen. For example, the display device 100 may insert a visible or invisible watermark into the content displayed on the display as predetermined response information, and the electronic device 200 may check whether the display device 100 is the device currently displaying the content by identifying or extracting the visible or invisible watermark from the image of the screen of the display device 100 obtained by a camera.

[0174] In operation 640, when the electronic device 200 checks (eg, determines whether) the device transmitting the broadcast signal is the display device currently displaying the content, the electronic device 200 may transmit a content sharing request for sharing the content to the display device.

[0175] According to an embodiment of the present disclosure, when checking, the electronic device 200 may automatically send a content sharing request to the display apparatus 100 .

[0176] According to an embodiment of the present disclosure, when checking, the electronic device 200 may ask the user whether he or she really wants to share content, and when there is a user selection or input for the inquiry, the electronic device 200 may send a content sharing request to the display apparatus 100 .

[0177] According to an embodiment of the present disclosure, the electronic device 200 may transmit a content sharing request to the display apparatus 100 using any of various short-range communication technologies.

[0178] According to an embodiment of the present disclosure, when sending a content sharing request, the electronic device 200 may include and send information for requesting to filter graphic content such as a graphic user interface and to send only video content.

[0179] In operation 650 , the electronic device 200 may receive at least a portion of the content output to the display of the display device in response to the content sharing request from the display device 100 through the content sharing technology.

[0180] According to an embodiment of the present disclosure, the electronic device 200 can output the content received from the display device 100 through the display of the electronic device 200 using the content sharing technology. That is, before receiving and displaying the content through the content sharing technology, the electronic device 200 outputs the image of the display screen of the display device 100 obtained by the camera of the electronic device 200 as a preview, but when the electronic device 200 receives the content through the content sharing technology, the electronic device 200 can display the content received through the communication network on the display. Therefore, because the electronic device 200 displays the content received through the communication network, it is possible to prevent and / or reduce the disadvantages of capturing the image of the screen of the display device 100 and displaying the image on the display, for example, also obtaining images around the display device, other objects are reflected on the display screen of the display device, or the screen of the display device is distorted.

[0181] According to an embodiment of the present disclosure, the electronic device 200 may provide various user interfaces for implementing operations such as recording or capturing content displayed on the display of the electronic device 200, and may perform operations of recording or capturing content based on user input received through the provided user interfaces.

For example, the display device 100 may retrieve and display content stored in an internal memory of the display device 100, may display content received from an external input device connected through a wired / wireless interface, or may display content received through the Internet or a broadcast network. The content displayed on the display device 100 may include various types of content. For example, the content may include various types of content, such as moving image content, still image content, and game content.

[0184] In operation 702, the electronic device 200 may obtain content displayed on the screen of the display device 100 through, for example, a camera. In order to allow the user of the electronic device 200 to capture or record at least a portion of the content displayed on the display device 100 while enjoying the content displayed on the display device 100, the electronic device 200 may use a camera application of the electronic device 200 to make the camera of the electronic device 200 face the screen of the display device 100, obtain an image of the screen of the display device 100 through the camera, and may display a preview image on the display of the electronic device 200.

[0185] Not necessarily in Figure 7 Operation 702 is shown to be performed before operation 705 of detecting a broadcast signal, and operation 702 only needs to be performed before operation 706 .

[0186] In operation 703 , the display apparatus 100 may recognize that content displayed on the display is sharable content.

[0187] The display device 100 according to an embodiment of the present disclosure needs to identify whether the content is shareable content, so as to share the content with other adjacent devices according to the content sharing technology, and the content is available through the content sharing operation among the multiple content displayed on the display device 100. Whether the content is shareable content can be identified by checking whether the content is free of copyright issues.

[0210] The display device 100 may insert and output a predetermined watermark into the content output to the display as identification response information. Fig. 9, the display device 100 may output text 900 that reads, for example, <capture> to the content as a predetermined watermark. In this way, when the display device 100 includes and outputs the text 900 that may be a watermark in the output content, the electronic device 200 that captures the image of the screen of the display device 100 may obtain the image of the screen of the display device 100 including the text 900, and may check whether the display device currently captured by the electronic device 200 is a device that transmits a broadcast signal including status information by extracting or recognizing the text 900 as a predetermined watermark from the obtained image. Although in Fig. 9 The predetermined watermark is visible to the user, but the predetermined watermark may be invisible.

[0211] Return to reference Figure 7 , when the display apparatus 100 outputs the identification response information indicating the response to the device identification request signal at operation 708, the electronic device 200 may obtain an image of the screen of the display apparatus 100 including the identification response information, and may identify the identification response information in the obtained image at operation 709. The electronic device 200 may check the display apparatus 100 based on the identified identification response information. That is, the electronic device 200 may check whether the device to which the electronic device 200 sends the device identification request signal is the same as the display device whose screen image is currently captured by the electronic device 200.

[0212] In operation 710 , when checking of the display apparatus 100 is completed, the electronic device 200 may transmit a sharing request signal for sharing the content displayed on the display apparatus 100 to the display apparatus 100 .

[0213] According to an embodiment of the present disclosure, when checking, the electronic device 200 may automatically send a content sharing request to the display apparatus 100 .

[0215] According to an embodiment of the present disclosure, the electronic device 200 may use any of various short-range communication technologies to send a content sharing request to the display apparatus 100. The various short-range communication technologies may include Wi-Fi communication technology, Bluetooth communication technology, and BLE communication technology.

[0216] According to an embodiment of the present disclosure, the electronic device 200 may perform an operation of establishing a connection with the display apparatus 100 by sending a BT MAC, a Wi-Fi MAC, or a P2P MAC using a Wi-Fi direct communication technology, and may send a content sharing request through the connection.

[0217] In operation 711 , when the display apparatus 100 receives a content sharing request from the electronic device 200 , the display apparatus 100 may transmit the sharing request content to the electronic device 200 .

[0218] According to an embodiment of the present disclosure, the display apparatus 100 may transmit at least a portion of the content displayed on the display to the electronic device 200 in response to a content sharing request of the electronic device, using any of various content sharing technologies.

[0219] According to an embodiment of the present disclosure, the display device 100 can use content sharing technology to send the entire content displayed on the display to the electronic device. In this case, when the content displayed on the display includes video content and graphic content (such as a user interface overlaid on the video content), the display device 100 can use content sharing technology to send both the video content and the graphic content. In this case, the graphic content sent in addition to the video content may be content that the user of the electronic device does not want.

[0220] According to an embodiment of the present disclosure, the display device 100 can use content sharing technology to send only some of the content displayed on the display (i.e., only the video content) to the electronic device. Because the user of the electronic device may want to use only the video content, the display device 100 can filter and send additional content such as a user interface other than the video content.

[0221] In operation 712 , the electronic device 200 may receive at least a portion of the content output to the display of the display apparatus in response to the content sharing request from the display apparatus 100 using the content sharing technology.

[0222] According to an embodiment of the present disclosure, the electronic device 200 can output the content received from the display device 100 through the display of the electronic device 200 through the content sharing technology. That is, before receiving and displaying the content through the content sharing technology, the electronic device 200 outputs the image of the display screen of the display device 100 obtained through the camera of the electronic device 200 as a preview, but when the electronic device 200 receives the content through the content sharing technology, the electronic device 200 can display the content received through the communication network on the display. Therefore, because the electronic device 200 displays the content received through the communication network, it is possible to prevent and / or reduce the disadvantages of capturing the image of the screen of the display device 100 and displaying the image on the display, for example, also obtaining images around the display device, other objects are reflected on the display screen of the display device, or the screen of the display device is distorted.

[0223] Fig.10 is a diagram illustrating an example in which an electronic device outputs shared content received from a display device according to various embodiments.

[0224] refer to Fig.10 Because the electronic device 200 captures an image of the screen of the display device 100 through the camera using the camera application before receiving the shared content from the display device 100 , the display of the electronic device 200 may display a background image 40 including a screen image 30 of the display device and the surroundings of the display device 100 .

[0225] When the electronic device 200 checks the display device 100, sends a content sharing request to the display device 100, and receives the sharing request content, the electronic device 200 can directly output the shared content on the display. Therefore, the display of the electronic device 200 can directly display the shared content 1000 received from the display device 100, rather than the screen image of the display device obtained by the camera.

[0226] According to an embodiment of the present disclosure, when the electronic device 200 outputs the shared content received from the display device 100, the electronic device 200 can output the shared content through the camera application. Therefore, in this case, for the part other than the part outputting the shared content, the user interface of the camera application can be used as it is.

[0227] According to an embodiment of the present disclosure, when the electronic device 200 outputs the shared content received from the display device 100, the electronic device 200 can output the shared content through the content sharing application. Therefore, in this case, for the part other than the part outputting the shared content, the user interface of the content sharing application can be used as it is.

[0228] According to an embodiment of the present disclosure, when the electronic device 200 outputs shared content received from the display apparatus 100, the electronic device 200 may output the shared content through a dedicated application.

[0229] According to an embodiment of the present disclosure, the electronic device 200 may provide various user interfaces for implementing operations such as recording or capturing content displayed on the display of the electronic device 200, and may perform operations of recording or capturing content based on user input received through the provided user interfaces.

[0230] Fig.11 is a diagram illustrating an example user interface that may be provided when the electronic device 200 displays shared content according to various embodiments.

[0231] refer to Fig.11 , the electronic device 200 may display the shared content 1000 received from the display apparatus 100 , and may provide a user interface 1100 for manipulating the shared content 1000 .

[0232] According to an embodiment of the present disclosure, the user interface 1100 may include a capture item 1110 for capturing displayed shared content in units of images. When the capture item 1110 is selected, the electronic device 200 may capture and store an image of the content displayed when the capture item 1110 is selected.

[0233] According to an embodiment of the present disclosure, the user interface 1100 may include a recording item 1120 for recording the displayed shared content as a video within a specified period of time. When the recording item 1120 is selected, the electronic device 200 may store the content from the time when the recording item 1120 is selected to the time when the recording item 1120 is deselected.

[0234] According to an embodiment of the present disclosure, the user interface 1100 may include an exit item 1130 for ending display of the shared content. When the exit item 1130 is selected, the electronic device 200 may end displaying the shared content and may return to a screen state before displaying the shared content.

[0235] Fig.12 is a signal flow chart illustrating an example method of operating a display device and an electronic device to share content according to various embodiments. Figure 7 In the example of FIG. 1 , the electronic device 200 checks the display device 100 and then automatically sends a content sharing request signal, but in Fig.12 In the example, the electronic device 200 may check the display apparatus 100 and may then send a content sharing request signal according to the user's selection.

[0236] refer to Fig.12 , operations 1201 to 1209 and Figure 7Operations 701 to 709 are the same or similar, and thus, repeated descriptions may not be provided.

[0237] In operation 1210, when checking the display device in operation 1209, the electronic device 200 may provide a user interface for asking whether to capture the content displayed on the display device. Because the user attempted to capture an image of the display device 100 by facing the camera of the electronic device 200 toward the display device 100 in the previous operation (e.g., operation 1202 or 1206), the electronic device 200 may determine that the user has the intention to capture the content displayed on the display device 100. Therefore, in Figure 7 In the embodiment, the electronic device 200 is configured to automatically send a content sharing request signal to the display device immediately after checking the display device. Fig.12 In the example of , a user interface for rechecking the user's intent can be provided.

[0238] In operation 1211 , the electronic device 200 may receive a user input selecting content capture.

[0239] In operation 1212 , the electronic device 200 may transmit a signal for requesting sharing of content to the display apparatus 100 based on the received user input.

[0240] Operations 1212 to 1214 and Figure 7 Operations 710 to 712 of FIG. 7 are the same or similar, and thus, repeated descriptions may not be provided.

[0241] Fig.13 is a diagram illustrating an example process in which an electronic device checks a user's capture intention after checking a display device according to various embodiments.

[0242] refer to Fig.13 Before the display device is checked and the electronic device 200 sends a content sharing request to the display device 100, the electronic device 200 may output a user interface 1300 for inquiring about the user's intention to capture content again. The user interface 1300 may include a message saying, for example, "Do you want to capture or record an image? OK, cancel."

[0243] When the user selects <OK> in response to the user interface 1300, the electronic device 200 may send a content sharing request to the display device 100, and when receiving shared content from the display device 100 according to the content sharing request, the electronic device 200 may display the received shared content 1000 on the display. When the user selects <Cancel> in response to the user interface 1300, the electronic device 200 may not send the content sharing request and may end the operation.

[0244] When playing video content, the display device 100 may output a notification message for notifying the user, an advertising message, or a user interface for menu selection together with the video content. The notification message may include a message indicating a chat text notification of a chat service or a message received by an email, a disaster alert text message, or an alert message such as the usage environment or status of the display device 100. However, according to the example of the present disclosure, because the display device 100 sends content to the electronic device 200 to enable the user to utilize the content displayed on the display device 100 (i.e., the video content as the main content) for personal use, the notification message may not be the content that the user wants. Therefore, it may be preferable to prevent and / or reduce additional content other than the video content from being recorded or captured when the user records or captures video content in the electronic device 200. Reference will be made to Figures 14 to 19 Various examples of filtering contents other than video contents from among the plurality of pieces of contents displayed on the display device 100 are described in more detail.
