Description



PRIORITY

[0001] This application claims priority under 35 U.S.C. .sctn.119(a) to a Korean Patent Application filed on Feb. 17, 2016, in the Korean Intellectual Property Office and assigned Serial No. 10-2016-0018627, the entire disclosure of which is incorporated herein by reference.

BACKGROUND

[0002] 1. Field of the Invention

[0003] The present disclosure relates generally to electronic devices, and more particularly, to an electronic device that displays and shares video with an external electronic device wirelessly connected thereto, in real-time.

[0004] 2. Description of Related Art

[0005] With the development of mobile communication technology and processor technology, portable terminals (i.e., electronic devices) have been equipped with various functions as well. Electronic devices have been designed to include a touch panel-based display, which is capable of displaying videos created through various functions thereon. As used herein, the term "video" refers to a video or an image related to an application, web browser, video content, a display screen, etc.

[0006] As many electronic devices are capable of transmitting/receiving data to/from the same or different types of external devices via wired/wireless communication modes, when the electronic device is equipped with a video sharing technology (or a mirroring technology) the device is capable of simultaneously displaying video on both the electronic device and an external device. Video sharing technology allows an electronic device with a display to share screen data with an external device in such a way that the electronic device is able to transmit video displayed on the display screen of the electronic device to the external device, in a peer-to-peer (P2P) mode, via short-range wireless communication, such as WiFi, etc. The external device displays the received video on the display screen, thereby simultaneously displaying the same screen on both the electronic device and the external device. In general, video sharing technology has been used in situations when video on an electronic device with a relatively small display size needs to be displayed on a relatively large display size of an external device.

[0007] Conventional video sharing technologies of electronic devices establish a wireless communication connection between a source apparatus configured to transmit video and a sink apparatus configured to display video received from the source apparatus. The video is continuously transmitted therebetween until the connection is disconnected. When a user of the source apparatus wants to stop sharing a video with the sink apparatus, the user must manually release the wireless communication connection from the sink apparatus. When the user of the source apparatus wants to resume the transmission of the video to the sink apparatus, the user must manually operate to establish the wireless communication connection with the sink apparatus.

[0008] Therefore, when a user pauses the sharing of a video and then resumes sharing the video between the source and sink apparatuses via conventional video sharing technologies, the user is required to perform a number of processes, such as releasing the connection, searching for the sink apparatus, establishing the connection, etc., which causes user inconvenience.

SUMMARY

[0009] The present disclosure has been made to address the above-mentioned problems and/or disadvantages, and to provide at least the advantages described below.

[0010] Accordingly, an aspect of the present disclosure provides a method for an electronic device to control video sharing between a source apparatus and a sink apparatus, in such a way as to establish a connection for sharing video between the source apparatus and the sink apparatus, pause sharing of the video without additionally performing a separate connection release, and resume the sharing of the video.

[0011] In accordance with an aspect of the present disclosure, an electronic device is provided. The electronic device includes a display, a communication circuit, a control circuit, and a memory electrically connected to the control circuit, where the memory stores instructions enabling the control circuit to control the communication circuit to transmit a first video to an external device connected to the electronic device, when a video sharing function is executed, display an icon on the display, when transmitting the first video, and control the communication circuit to pause the transmission of the first video and to transmit a second video to the external device, in response to a first input applied to the icon.

[0012] In accordance with another aspect of the present disclosure, a method of an electronic device for controlling video sharing is provided. The method includes transmitting a first video to an external device, when a video sharing function is executed, displaying an icon on a display of the electronic device, when transmitting the first video, and pausing the transmission of the first video and transmitting a second video to the external device, in response to a first input applied to the icon.

[0110] Hereinafter, various embodiments of the present disclosure describe a method of sharing video, pausing transmission of the video, and resuming transmission of the video, with reference to FIGS. 4A to 9.

[0111] In the present disclosure, when a video sharing function is executed in an electronic device, the electronic device serves as a source apparatus configured to transmit video to an external device.

[0112] Accordingly, when the video sharing function is executed, the external device serves as a sink apparatus configured to receive video from the electronic device and display the received video. The external device may be the same type as the electronic device.

[0113] Alternatively, the external device may be a device that differs in type from the electronic device, e.g., a digital TV, a monitor device, etc. The external device according to the present disclosure may be various types of electronic devices which are equipped with a wireless communication function and a display function.

[0114] In the following description, the electronic device is a portable terminal (a mobile device) with a relatively small display size and the external device is a television with a large display size; however, the present disclosure is not limited to the embodiments described.

[0115] Further, the electronic device and the external device are connected to each other, using a wireless mode, such as via WiFi, Bluetooth, NFC, GNSS, etc. The external device receives video data from the electronic device via the wireless mode and displays the received video data on the display screen.

[0116] The video sharing function is a function that transmits a video from an electronic device to an external device in wireless mode and displays the video on the display screen of the external device. When the video sharing function is executed, the electronic device operates in a first mode where a first video (e.g., a content video or a video displayed on the display screen of the electronic device) is transmitted to an external device, in real time, and in a second mode where the transmission of the first video is paused and a second video (e.g., a video corresponding to a freeze screen, or a still image) that differs from the first video is transmitted to an external device. When the video sharing function is executed, the electronic device establishes the wireless communication connection with an external device, and maintains a communication channel (e.g., a data channel and a control channel) with the external device in the first mode and the second mode.

[0117] FIGS. 4A and 4B illustrate a method of sharing video between an electronic device and an external device, according to an embodiment of the present disclosure.

[0118] Referring to FIG. 4A, an electronic device 410 and an external device 1000 are provided. When a video sharing function is executed and the electronic device 410 and the external device 1000 are connected to each other in wireless mode, the external device 1000 is capable of displaying the same video as that displayed on the display screen of the electronic device 410. For example, in a state where the electronic device 410 displays a home screen showing icons corresponding to various applications on the display screen, when the video sharing function is executed, the electronic device 410 transmits the video of the home screen to the external device 1000, and then the external device 1000 displays the same home screen as that of the electronic device 410 on the display screen.

[0119] Referring to FIG. 4B, an electronic device 420 and the electronic device 1000 are provided. When the electronic device 420 transmits a content video to the external device 1000, the external device 1000 displays the received content video on the display screen of the external device 1000. In addition, the electronic device 420 may display, on a display screen of the electronic device 420, a control video for controlling the playback of the transmitted content video, simultaneously or at any other time, when the external device 1000 displays the received content video.

[0120] As shown in FIG. 4B, the control video is configured in such a way that a name of content and an icon showing a list of executable content items are located on the top and a play slide bar, and an icon for searching for content and pausing or playing content and a volume control icon are shown on the bottom. The control video shown in FIG. 4B is provided for illustration purpose only and the present disclosure is not limited thereto.

[0121] In various embodiments, the electronic device 420 is capable of transmitting content video to the external device 1000, in a streaming mode, in real-time.

[0122] When the video sharing function is executed and the electronic device 410 or 420 and the external device 1000 are connected to each other in wireless mode, the electronic device 410 or 420 transmits a video to the external device 1000 and displays, on the display screen of the electronic device 410 and 420, an icon 430 for pausing the transmission of the video, resuming the transmission of the video, or releasing the connection with the external device 1000. The icon 430 is displayed on part of the screen area of the electronic device 410 or 420 while transmitting the first video or pausing the transmission of the first video. The icon 430 may not be displayed on the display screen of the external device 1000.

[0123] The icon 430 may change to a floating state according to a user input (e.g., a long touch). When the icon 430 is in a floating state, it may move on the display screen according to a user input (e.g., a drag or a flick).

[0124] FIG. 5 is a block diagram of an electronic device, according to an embodiment of the present disclosure.

[0125] Referring to FIG. 5, an electronic device 500 is provided. The electronic device 500 includes a control circuit 510, a memory 520, a communication circuit 530, a display 540 and an audio processing circuit 550. The electronic device 500 may also be modified in such a way that part of the components are removed or replaced with equivalent components. The electronic device 500 may further include part of the components in the electronic device 101 shown in FIG. 1 and/or the electronic device 201 shown in FIG. 2.

[0126] The display 540 displays video. The display 540 may be implemented with LCD, LED display, an OLED display, a MEMS display, an electronic paper display, etc. The display 540 may further include part of the components in the display 160 shown in FIG. 1 and/or the display 260 shown in FIG. 2. The display 540 includes a touch screen panel. In this case, the touch screen panel detects a touch input or a hovering input applied to the window of the display 540.

[0127] The communication circuit 530 transmits/receives data to/from the external device 1000. The communication circuit 530 may include part of the components in the communication interface 170 shown in FIG. 1 and/or in the communication module 220 shown in FIG. 2. The communication circuit 530 communicates with the external device 1000 in a short-range wireless communication mode, e.g., Wi-Fi, etc. The communication circuit 530 is configured to include two or more antennas that are capable of performing the transmission/reception of data via different frequency bands. When the electronic device 500 receives video in a streaming mode via a network and transmits the received video to the external device 1000, in real-time, using the video sharing function, the communication circuit 530 receives the streaming videos from an access point connected to the network via one antenna and transmits the received videos to the external device 1000 via another antenna.

[0128] The memory 520 is implemented to include a volatile memory and a non-volatile memory, but is not limited thereto. The memory 520 is electrically connected to the control circuit 510. The memory 520 stores instructions enabling the control circuit 510 to perform corresponding functions. The instructions include control commands for instructing the control circuit 510 to perform arithmetic operations, logic operations, data transfer function, input/output functions, etc.

[0129] The control circuit 510 controls components in the electronic device 500, performs functions related to communication, and processes data. The control circuit 510 includes part of the components in the processor 120 shown in FIG. 1 and/or in the application processor 210 shown in FIG. 2. The control circuit 510 is electrically connected to components in the electronic device 500, such as, the display 540, the memory 520, the communication circuit 530, the audio processing circuit 550, etc.

[0130] The control circuit 510 is not limited to the operations/functions and the data process function of the electronic device 500 described above. The control circuit 510 controls the display 540 to display video and the communication circuit 530 to transmit the video to the external device 1000. The control circuit 510 loads instructions from the memory 520 and executes the instructions to perform corresponding functions.

[0131] The audio processing circuit 550 processes audio signals and amplifies and outputs the signals. The audio processing circuit 550 may output the audio signals via a speaker built in the electronic device 500 or earphones (or an external speaker) connected in wired/wireless mode to the electronic device 500.

[0132] The electronic device 500 is capable of establishing a wireless communication connection with the external device 1000 according to the execution of the video sharing function. For example, the communication circuit 530 of the electronic device 500 connects to the external device 1000, in wireless mode, via Wi-Fi direct (or Wi-Fi P2P). When the electronic device 500 receives a discovery signal, broadcast periodically from the external device 1000 via the communication circuit 530, the electronic device 500 considers that it can connect to the external device 1000 and attempts to connect to the external device 1000 according to a user's selection. The communication circuit 530 forms a group with the selected external device 1000 and creates a session with the external device 1000. The created session may be maintained, regardless of the transmission of a first video, until the communication circuit 530 is disconnected from the external device 1000.

[0133] When the electronic device 500 establishes the wireless communication connection with the external device 1000 according to the execution of the video sharing function, the electronic device 500 transmits a first video to the external device 1000 via the communication circuit 530. The first video may be the same video (e.g., a home screen) as that displayed on the display 540 of the electronic device 500. Alternatively, the first video may be a content video which is stored in the memory 520 of the electronic device 500 or is received in a streaming mode from external to the electronic device 500 via the communication circuit 530.

[0134] The control circuit 510 displays a first video or a control video for controlling the first video on the display 540, simultaneously or at any other time, when the communication circuit 530 transmits the first video to the external device 1000. For example, when the first video is a video displayed on a home screen of the electronic device 500, the control circuit 510 displays the first video on the display 540. When the first video is a content video, the control circuit 510 displays the control video on the display 540.

[0135] When the first video is transmitted, simultaneously or at any other time, the control circuit 510 displays an icon on at least part of the display 540. The icon is for pausing execution of the video sharing function, resuming transmission of the video, or releasing the connection with the external device 1000. The icons displayed according to the execution of the video sharing function will be described in detail with reference to FIGS. 8C to 8F.

[0136] The icon may be implemented with a toggle button. When the control circuit 510 detects a first input and a second input applied to the icon, the control circuit 510 changes the video sharing function from a first mode to a second mode or vice versa. The first mode refers to an operation where the control circuit 510 transmits the first video to the external device 1000. The second mode refers to an operation where the control circuit 510 pauses the transmission of the first video and transmits, to the external device 1000, a second video that differs from the first video.

[0137] The first input and the second input may be the same type of input. For example, the first input and the second input may be a touch input or a hovering input applied to the icon. The display 540 detects the first input and the second input via the touch screen panel and transfers the detected input to the control circuit 510.

[0138] The second input refers to an input detected in a second mode for pausing the transmission of the first video. In addition, a third input refers to an input detected in a first mode and a second mode. The third input differs from the first input and the second input.

[0139] When the control circuit 510 detects a first input applied to the displayed icon, it pauses the transmission of the first video and transmits a second video to the external device 1000 via the communication circuit 530. The second video may be a video corresponding to a freeze screen. For example, the second video may be a still image containing text, e.g., pause. The video sharing function changes a first mode to a second mode according to the first input. The second mode is a state pausing the transmission of the first video, maintaining the wireless communication connection between the communication circuit 530 and the external device 1000, like the first mode. In the second mode, the session between the communication circuit 530 and the external device 1000 is maintained and the channel for performing the transmission of data (e.g., a data channel and a control channel) is also maintained.

[0140] When a conventional electronic device continuously or automatically transmits the first video to the external device 1000, the conventional electronic device may transmit video or data that the user does not want to share, e.g., a list of photographs, personal information, along with the first video. In this case, in order to pause the sharing of the first video with the external device 1000, the user needs to release the wireless connection with the external device 1000. To resume sharing the first video, the user needs to operate the conventional electronic device to search for the external device 1000 and to establish the connection, which causes user inconvenience.

[0141] To resolve the above-mentioned problem, the electronic device 500, according to various embodiments of the present disclosure, operates in a second mode pausing the execution of the video sharing function, or in sharing the first video. During the second mode, the electronic device 500 transmits a second video corresponding to a freeze screen to the external device 1000, while maintaining the connection with the external device 1000. In addition, during the second mode, the external device 1000 displays the received second video on the display screen, thereby informing the user that the video sharing function is in a `pause` state.

[0142] The second video may be a still image corresponding to a pause state of the screen. The second video will be described in detail with reference to FIGS. 7A and 7B.

[0143] The control circuit 510 controls the communication circuit 530 to pause the transmission of a first video, in response to the detection of a first input, and to transmit a second video as a still image at a preset period. The external device may release the connection with the electronic device 500 when additional video data is not received from the electronic device 500 for a preset period of time. To resolve the problem, the electronic device 500 is performs a transmission of a second video to the external device 1000 periodically (e.g., every one minute or five minutes). In this case, the electronic device 500 maintains the wireless communication connection with the external device 1000 in a second mode.

[0144] When the electronic device 500 operates the video sharing function in the second mode according to the first input, a second video may be transmitted only once.

[0145] When the video sharing function is executed, the control circuit 510 transmits the first video to the external device 1000, and simultaneously or at any other time, displays the first video as shown in FIG. 4A or a control video for controlling the first video as shown in FIG. 4B on the display 540.

[0146] When the control circuit 510 displays the first video on the display 540 and the control circuit 510 detects a first input, transmission of the first video to the external device 1000 may be paused. In this case, the control circuit 510 may still display the first video on the display 540.

[0147] When the control circuit 510 displays a control video for controlling the first video on the display 540 and the control circuit 510 detects a first input, the first video is displayed on the display 540. That is, while the electronic device 500 displays the first video on the display 540, the external device 1000 displays a second video on the display screen. In this case, the user of the electronic device 500 views the first video on the display 540 of the electronic device 500. However, users viewing the external device 1000 do not view the first video on the display screen of the external device 1000 and instead view the second video.

[0148] The control circuit 510 controls the communication circuit 530 to resume the transmission of the first video, in response to the detection of a second input applied to an icon. The second input may be the same type as the first input (e.g., a touch input or a hovering input applied to an icon) received in the second mode.

[0149] The control circuit 510 controls the communication circuit 530 to release the wireless communication connection with the external device 1000, in response to the detection of a third input applied to an icon. The third input may be an input that differs in type from the first input and the second input. For example, the third input may be a touch input for dragging and dropping an icon from on location to another. The third input is detected in a first mode and a second mode. Therefore, the third input may terminate the video sharing function while transmitting the first video or pausing the transmission of the first video.

[0150] The control circuit 510 controls the communication circuit 530 to transmit the first video and first audio data corresponding to the first video to the external device 1000. In this case, while the electronic device 500 displays the first video or the control video for controlling the first video on the display 540, the external device 1000 outputs the first video and the corresponding first audio data. When the control circuit 510 detects a first input, it pauses the transmission of the first video and the first audio data, displays the first video on the display 540, and transfers the first audio data to the audio processing circuit 550, thereby enabling the audio processing circuit 550 to output the first audio data via a speaker, built in the electronic device 500, or earphones (or an external speaker) connected in wired/wireless mode to the electronic device 500. In another embodiment, the control circuit 510 may control not to output the first audio data via the external device 1000 or the electronic device 500, in response to the first input.

[0151] When the control circuit 510 detects a second input, the first video and the first audio data are transmitted to the external device 1000 as before detecting the first input. In this case, the first audio data may not be output via the electronic device 500.

[0152] The icon may include a first sub icon related to the transmission of a first video and a second sub icon related to the transmission of first audio data.

[0153] The control circuit 510 pauses/resumes the transmission of the first video to the external device 1000, in response to the detection of an input applied to the first sub icon. The control circuit 510 also pauses/resumes the transmission of the first audio data to the external device, in response to the detection of an input applied to the second sub icon. Therefore, the user of the electronic device 500 may selectively transmit or pause the transmission of the first video and the first audio data, separately and independently, to the external device 1000.

[0154] The first sub icon may vary in type according to a condition as to whether to transmit the first video or to pause the transmission of the first video, and the second sub icon may vary in type according to a condition as to whether to transmit the first audio data or to pause the transmission of the first audio data. The first sub icon and the second sub icon will be described in detail with reference to FIG. 8F.

[0155] FIGS. 6A and 6B are block diagrams illustrating data flow between an electronic device and an external device in a first mode and a second mode, when a video sharing function is executed, according to an embodiment of the present disclosure.

[0156] Referring to FIG. 6A an electronic device 600a and the external device 1000, in a first mode when the video sharing function is executed, is provided, i.e., when the electronic device 600a transmits a first video to the external device 1000.

[0157] The electronic device 600a includes a control circuit 610a, a memory 620a, a communication circuit 630a, a display 640a, and an audio processing circuit 650a. When the video sharing function is executed, the control circuit 610a establishes a wireless communication connection with the external device 1000, operates in a first mode, and transmits a first video to the external device 1000. More specifically, the control circuit 610a synchronizes a first video with first audio data corresponding to the first video and transfers the first video and the first audio data to the communication circuit 630a. The communication circuit 630a transmits the first video and the first audio data to the external device 1000.

[0158] When the first video is transmitted, simultaneously or at any other time, the control circuit 610a displays the first video or a control video for controlling playback of the first video on the display 640a. The first mode may be set in such a way that an audio signal is not output via the audio processing circuit 650a of the electronic device 600a, but first audio data is output via the external device 1000.

[0159] Although FIG. 6A illustrates a method by which both the first video and the first audio data are transmitted to the external device 1000, the control circuit 610a may pause the transmission of the first video or the first audio data according to a user's selection of an icon. In this case, the icon may include a first sub icon related to the transmission of a first video and a second sub icon related to the transmission of first audio data.

[0160] Referring to FIG. 6B an electronic device 600b and the external device 1000, in a second mode when the video sharing function is executed, is provided, i.e., when the electronic device 600b pauses the transmission of a first video to the external device 1000.

[0161] The electronic device 600b includes a control circuit 610b, a memory 620b, a communication circuit 630b, a display 640b, and an audio processing circuit 650b. The control circuit 610b changes the video sharing function from a first mode to a second mode in response to detection of a first input. In the second mode, the control circuit 610b transfers a second video, corresponding to a freeze screen, to the communication circuit 620b, and the communication circuit 620b transmits the second video to the external device 1000. In this case, the control circuit 610b controls the communication circuit 620b to transmit the second video to the external device 1000 periodically (e.g., every one minute or five minutes) or once when the mode is changed to a second mode. In the second mode pausing the transmission of the first video, the wireless communication connection between the communication circuit 620b and the external device 1000 may be maintained.

[0162] The control circuit 610b displays the first video on the display 640b simultaneously when pausing the transmission of the first video to the external device 1000. The control circuit 610b transfers first audio data to the audio processing circuit 650b, thereby enabling the audio processing circuit 650b to output the first audio data to a speaker built in the electronic device 600b or to earphones (or an external speaker) connected in wired/wireless mode to the electronic device 600b.

[0163] When the control circuit 610b detects a second input applied to an icon, the control circuit 610b changes the mode to the first mode and resumes transmitting the first video and the first audio data, as described with respect to FIG. 6A.

[0164] FIGS. 7A and 7B illustrate screens of an electronic device and an external device, when pausing video sharing, according to an embodiment of the present disclosure.

[0165] Referring to FIG. 7A, an electronic device 710 and the external device 1000 are provided. When a first video is the same as that displayed on the display screen of the electronic device 710 (e.g., a home screen), both the displays of the electronic device 710 and the external device 1000 display the same first video in a first mode, as described with respect to FIG. 4A. In this case, the electronic device 710 further displays an icon for changing the mode of the video sharing function according to the execution of the video sharing function. The icon may be displayed on a separate layer that differs from the first video, and thus may not be displayed on the display screen of the external device 1000. In this case, the icon may be displayed in a form corresponding to the first mode.

[0166] When the electronic device 710 detects a first input, it transmits a second video to the external device 1000, while displaying the first video on the display screen of the electronic device 710. That is, while the electronic device 710 displays the first video on the display screen, the external device 1000 displays a second video representing that the transmission of a video is paused. The second video may be a still image containing text, e.g., the `PAUSE` image shown in FIGS. 7A and 7B, but is not limited thereto.

[0167] Referring to FIG. 7B, an electronic device 720 and the external device 1000 is provided. When the first video is a content video, the electronic device 720 transmits the first video to the external device 1000, as shown in FIG. 4B, and displays a control video for controlling the first video on the display screen of the electronic device 720. In this case, the electronic device 720 is creates an icon on a separate layer that differs from the control video, and displays the icon on the display screen of the electronic device 720.

[0168] When the electronic device 720 detects a first input, the electronic device 720 transmits a second video to the external device 1000 and displays the first video on the display screen of the electronic device 720. In this case, the icon may vary in type according to the change to the second mode. The control video may be displayed on a layer higher than that displaying the first video. When the electronic device 720 has not detected an input for a preset period of time, the electronic device 720 displays the first video and the icon without displaying the control video. Simultaneously or at any other time, the external device 1000 displays a second video representing pausing the transmission of a video.

[0169] FIGS. 8A to 8F illustrate screens of an electronic device and an external device, when the electronic device executes a video sharing function, pauses video sharing, and resumes the video sharing, according to an embodiment of the present disclosure.

[0170] Referring to FIG. 8A, a screen for executing a video sharing function in an electronic device 810 is provided.

[0171] The electronic device 810 displays a contact list containing details of a number of users on the display screen of the electronic device 810, based on a user input. When the electronic device 810 detects a user input (e.g., long touch input) applied to one of the contacts on the contact list, it displays a menu list related to the selected contact, as shown in FIG. 8A. The menu list may contain a menu icon 815 for executing a video sharing function. When the menu icon 815 is selected (touched/activated by a use input), the electronic device 810 establishes a wireless communication connection with an external device 1000 of the selected contact to share a video with the external device 1000.

[0172] Referring to FIG. 8B, a screen for executing the video sharing function in an electronic device 820 is provided. The electronic device 820 displays a menu list on the top of a home screen. The menu list may contain a menu icon 822 for executing a video sharing function. When the menu icon 822 is selected (touched/activated by a use input), the electronic device 820 displays a list 824 of connectable external devices. The external device list 824 is displayed with information regarding external devices connectable to the electronic device 820, e.g., external device names, icons corresponding to types of electronic devices, etc. When a user input is applied to one of the external devices on the external device list 824, the electronic device 820 establishes a wireless communication connection with the selected external device to share a video with the external device.

[0173] Referring to FIG. 8C, a screen of an electronic device 830 in a first mode of the video sharing function is provided. The electronic device 830 transmits a first video to the external device 1000 in a first mode, and simultaneously or at any other time, displays the first video on a display screen of the external device 1000. When the electronic device 830 displays the first video on the display screen of the external device 1000, simultaneously or at any other time, the electronic device 830 displays an icon 832 on the display screen of the electronic device 830 for changing the mode of the video sharing function. The icon 832 displayed in a first mode may have a form to show that the first video is being transmitted to the external device 1000, but is not limited to the form shown in FIG. 8C. The icon 832 is displayed on the display screen of the electronic device 830 and may not be displayed on the display screen of the external device 1000.

[0174] Referring to FIG. 8D, a screen of an electronic device 840 in a second mode of the video sharing function is provided.

[0175] The electronic device 840 pauses the transmission of a first video to the external device 1000 in response to the detection of a first input (e.g., a touch input or a hovering input) applied to the icon 832, shown in FIG. 8C, displayed in the first mode. In this case, the electronic device 840 still displays the first video on the display screen of the electronic device 840. The icon 832 is changed to an icon 842 as the mode is changed to a second mode, as shown in FIG. 8D. The icon 842 displayed in the second mode may have a form to show a state of pausing the transmission of the first video to the external device 1000, but is not limited to the form shown in FIG. 8D. The icon 842 is displayed on the display screen of the electronic device 840 and may not be displayed on the display screen of the external device 1000.

[0176] Referring to FIG. 8E, a screen of an electronic device 850 having released the wireless communication connection with the external device 1000 is provided.

[0177] The electronic device 850 releases the wireless communication connection with the external device 1000, in response to the detection of a third input applied to an icon 852. For example, when the electronic device 850 detects a long touch input applied to the icon 852, an area 854 for removing icons is displayed on the top of the display screen of the electronic device 850. When the user drags and drops the icon 852 in the area 854, the electronic device 850 considers the user input to be a third input.

[0178] When the electronic device 850 detects the third input, the wireless communication connection with the external device 1000 is released. In this case, the electronic device 850 pauses the transmission of the first video and the second video to the external device 1000 and removes the displayed icon 854. When the electronic device 850 releases the wireless communication connection with the external device 1000, the first video remains displayed on the display screen of the electronic device 850.

[0179] Although FIG. 8E illustrates a method in which the electronic device 850 releases the wireless communication connection with the external device 1000 during the transmission of the first video, the electronic device 850 may also release the wireless communication connection with the external device 1000 in a state of pausing the transmission of the first video, as shown in FIG. 8D. That is, while the electronic device 850 displays an icon 842 showing a state of pausing the transmission of the first video, as shown in FIG. 8D, when the icon 842 is dragged and dropped in the area 854, shown in FIG. 8E, the electronic device 850 releases the wireless communication connection with the external device 100.

[0180] The icons shown in FIGS. 8C to 8E are provided for a better understanding the present disclosure, and the icons may be implemented in various forms. For example, when an icon is long touched, the electronic device may display a list of menus for pausing the transmission of a first video, resuming transmission of the first video, releasing the connection with an external device, etc. In this case, when one of the menus on the list is selected, the electronic device performs a function corresponding to the selected menu. Alternatively, the electronic device may display, on the display screen, a number of icons corresponding to each of the functions for pausing the transmission of a first video, resuming transmission of the first video, releasing the connection with an external device, etc.

[0181] Referring to FIG. 8F, an electronic device 860 displaying an icon 862 is provided. The icon 862 is implemented to include a first sub icon 862a related to the transmission of a first video and a second sub icon 862b related to the transmission of first audio data. In this case, the first sub icon 862a and the second sub icon 862b may be implemented with a toggle button, respectively.

[0182] When the electronic device 860 transmits the first video and the first audio data to the external device 1000 according to the execution of the video sharing function, the first sub icon 862a may be displayed in a form corresponding to the transmission of the first video and the second sub icon 862b may be displayed in a form corresponding to the transmission of first audio data.

[0183] When the electronic device 860 receives a user's first input (e.g., a touch input or a hovering input) applied to the first sub icon 862a, the transmission of the first video is paused and the form of the first sub icon 862a is changed to a form 864a showing a state of pausing the transmission of the first video. In addition, when the electronic device 860 receives a user's first input (e.g., a touch input or a hovering input) applied to the second sub icon 862b, the transmission of the first audio data is paused and the form of the second sub icon 862b is changed to a form 864b showing a state of pausing the transmission of the first audio data.

[0184] Therefore, the user of the electronic device 860 may selectively and independently transmit or pause transmission of the first video and the first audio data to the external device 1000.

[0185] In various embodiments, an electronic device is configured to include: a display; a communication circuit; a control circuit electrically connected to the display and the communication circuit; and a memory electrically connected to the control circuit. The memory stores instructions enabling the control circuit to: control the communication circuit to transmit a first video to an external device wirelessly connected to the electronic device, according to the execution of a video sharing function; display an icon on part of the display, simultaneously or at any other time, when transmitting the first video; and control the communication circuit to pause the transmission of the first video and to transmit a second video that differs from the first video to the external device, in response to the detection of a first input applied to the displayed icon.

[0186] The second video may be a video corresponding to a freeze screen.

[0187] The control circuit controls the communication circuit to transmit the second video to the external device at a preset period.

[0188] The control circuit controls the display to display the first video when transmitting the second video to the external device.

[0189] The first video is a content video and the control circuit displays a control video for controlling the output of the first video to the display, simultaneously or at any other time, when the first video is transmitted to the external device.

[0190] The control circuit controls the display to stop displaying the control video and to display the first video, in response to the detection of a second input.

[0191] The control circuit controls the communication circuit to resume the transmission of the first video, in response to the detection of a second input applied to the icon.

[0192] The control circuit releases the wireless communication connection between the communication circuit and the external device, in response to the detection of a third input applied to the icon.

[0193] The icon includes a toggle button for altering the video sharing function from a first mode to a second mode according to the first input and from the second mode to the first mode according to the second input.

[0194] The icon is displayed on a layer on the display screen, which differs from a layer displaying the first video.

[0195] The first input and the second input are the same type of input.

[0196] The control circuit controls the communication circuit to transmit the first video along with first audio data corresponding to the first video to the external device and to pause the transmission of the first video and the first audio data, in response to the detection of the first input.

[0197] The electronic device may further include an audio processing circuit for processing and outputting audio signals. The control circuit transfers the first audio data to the audio processing circuit in response to the detection of the first input.

[0198] FIG. 9 is a flowchart of a method for controlling video sharing in an electronic device, according to an embodiment of the present disclosure

[0199] In step 910, the electronic device displays a first video on the display screen of the electronic device. The first video may be a graphic user interface (GUI) created according to the operations of the electronic device, e.g., a home screen, a screen created according to the execution of applications, a content video stored in the memory of the electronic device or received from external systems, etc.

[0200] In step 920, the electronic device determines whether an input for executing a video sharing function is received. If the electronic device detects the input for executing the video sharing function, in step 930, the electronic device establishes a wireless communication connection with an external device. If the electronic device does not detect the input for executing the video sharing function, the electronic device returns to step 920.

[0201] In step 940, the electronic device transmits the first video to the external device. When the first video is the same video (e.g., a home screen) as that displayed on the display screen of the electronic device, the electronic device displays the first video on the display screen of the electronic device, simultaneously or at any other time, when the first video is transmitted to the external device. When the first video is a content video, the electronic device transmits the first video to the external device, and displays a control video for controlling the first video on the display screen of the electronic device.

[0202] The electronic device displays an icon on the display screen of the electronic device, simultaneously or at any other time when transmitting the first video to the external device. The icon is for pausing the execution of the video sharing function, resuming the transmission of the video, or releasing the connection with the external device. The icon may be displayed on a different layer than a layer displaying the first video, and thus may not be displayed on the display screen of the external device when the video is transmitted to the external device.

[0203] The electronic device may additionally transmit first audio data corresponding to the first video to the external device. In stem 950, the electronic device determines whether a first input applied to the displayed icon during the transmission of the first video is detected.

[0204] When the first input is detected, in step 960, the electronic device pauses the transmission of the first video and transmits a second video, which differs from the first video, to the external device. The electronic device performs the transmission of the second video to the external device at a preset period or periodically (e.g., every one minute or five minutes), or once when a first or third mode is changed to a second mode. In this case, the external device pauses the display of the first video on the display screen of the external device, and displays a second video corresponding to a freeze screen. In the second mode pausing the transmission of a first video, the wireless communication connection between the electronic device and the external device may be maintained.

[0205] The electronic device pauses the transmission of a first video to the external device, and simultaneously displays the first video on the display screen of the electronic device. The electronic device outputs first audio data to a built-in speaker or to earphones (or an external speaker) connected to the electronic device. The electronic device changes the form of the displayed icon to a form corresponding to the second mode in response to the detection of a first input.

[0206] When the first input is not detected, the electronic device returns to step 950. In step 970, the electronic device determines whether a second input applied to the displayed icon is detected. The second input may be the same type as the first input, e.g., a touch input or a hovering input.

[0207] When the second input is detected, in step 980, the electronic device resumes the transmission of the first video. That is, the electronic device performs the same operation as performed in step 940.

[0208] When the second input is not detected, the electronic device returns to step 970.

[0209] In step 990, the electronic device determines whether a third input applied to the displayed icon is detected. The third input differs in type from the first input and the second input. Although step 990 is described as being performed while the electronic device is in the second mode, i.e., after step 980, step 990 may alternatively be performed while the electronic device is in the first mode, i.e., after step 940.

[0210] When the third input is detected, in step 995, the electronic device releases the wireless communication connection with the external device.

[0211] When the third input is not detected, the electronic device returns to step 990.

[0212] In various embodiments, a method of controlling the sharing of videos via an electronic device is implemented to include transmitting a first video to an external device wirelessly connected to the electronic device, according to the execution of a video sharing function; displaying an icon on part of a display, simultaneously or at any other time, when transmitting the first video; and pausing the transmission of the first video, and transmitting a second video that differs from the first video to the external device, in response to the detection of a first input applied to the displayed icon.

[0213] The second video may be a video corresponding to a freeze screen.

[0214] The transmission of the second video includes transmitting the second video to the external device at a preset period

[0215] The first video is a content video. The method further includes displaying a control video for controlling the output of the first video to the display, simultaneously or at any other time, when the first video is transmitted to the external device.

[0216] The method further includes stopping the display of the control video on the display screen, and displaying the first video, in response to the detection of a second input.

[0217] The method further includes resuming the transmission of the first video, in response to the detection of a second input applied to the icon.

[0218] The transmission of a first video to an external device includes: transmitting the first video along with first audio data corresponding to the first video to the external device; and pausing the transmission of the first video and the first audio data, in response to the detection of the first input, and outputting the first audio data via the electronic device.

[0219] While the present disclosure has been described with reference to various embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the present disclosure, which is defined, not by the detailed description and embodiments, but by the appended claims and their equivalents.
