An electronic device is provided. The electronic device includes a display, a communication circuitry, memory storing one or more computer programs, and one or more processors communicatively coupled to the display, the communication circuitry, and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors, cause the electronic device to connect to an external display device, display a first screen on the display, transmit, to the external display device, first data related to a second screen differing from the first screen, display a third screen corresponding to the second screen, on at least a portion of the first screen, and, in response to a touch input on the third screen, transmit updated second screen-related second data to the external display device via the communication circuitry.

Electronic device for controlling external display device, and operation method thereof

An example source device includes a wireless communication module, a memory, and a processor. The processor may transmit an expanded screen, generated by the source device to be displayed on a sink device connected to the source device, to the sink device through the wireless communication module. The expanded screen may be a screen displayed on a display of the sink device in association with a first screen displayed on a display of the source device to expand a task space of the source device. The source device may identify a screen focused by an input device connected to the source device among the first screen displayed on the display of the source device and a second screen displayed on the display of the sink device. The source device may switch a processing scheme to process an input event generated by the input device, based on at least one of a display mode of the sink device or whether the focused screen is the first screen or the second screen.

Source device and sink device for sharing expanded screen, and methods of operating the same

An electronic device is provided. The electronic device includes a display, communication circuitry, and a processor operatively connected to the display and the communication circuitry, wherein the processor is configured to transmit audio data to an external device through the communication circuitry, receive a user input for adjustment of a volume level of an audio output through the external device, in response to the user input, check whether a first volume level being set in the electronic device is within a specified range, select one of the first volume level of the electronic device or a second volume level of the external device to be adjusted corresponding to the user input based on whether the first volume level being set in the electronic device is within the specified range, display a volume panel UI comprising the selected one of the first volume level or the second volume level and a graphic object indicating the one of the electronic device or the external device, when adjusting the selected one of the first volume level or the second volume level, and change the graphic object indicating the selected one of the electronic device or the external device to a graphic object indicating other of the electronic device or the external device and switch the selected one of the first volume level or the second volume level to other of the first volume level or the second volume level to be adjusted corresponding to the user input, when adjusting the other of the first volume level or the second volume level while displaying the volume panel UI.

Electronic device and method for controlling audio volume thereof

An example method of an electronic device according to various embodiments of the present disclosure may include indicating that a first screen related to a first application operating in a background state is being displayed in an external electronic device, connected to the electronic device, based on data transmitted from the electronic device; and displaying an object floating on a second screen being displayed on the electronic device.

Electronic device and method for sharing screen

An electronic device is disclosed. An electronic device comprises a display, a communication circuit configured to communicate with a first peripheral device, a memory configured to store first authentication information associated with the first peripheral device, and a processor, wherein the processor is configured to control the electronic device to: broadcast a first message via the communication circuit, receive a connection request message from the first peripheral device receiving the first message, authenticate the first peripheral device based on the first authentication information associated with the first peripheral device in response to the reception of the connection request message, and transmit screen data being displayed on the display to the first peripheral device via the communication circuit based on the authentication being valid.

Electronic device and method for sharing screen data

A method of an electronic device according to various embodiments of the present disclosure may comprise the operations of: indicating that a first screen related to a first application operating in a background state is being displayed in an external electronic device, connected to the electronic device, on the basis of data transmitted from the electronic device; and displaying an object floating on a second screen being displayed on the electronic device.

A receiver includes a sampler that samples first voltage levels corresponding to a first logical value of data and second voltage levels corresponding to a second logical value of the data, based on a sampling clock. An equalizer receives and adjusts the first and second voltage levels. A clock and data recovery circuit recovers the sampling clock, based on the first and second voltage levels from the equalizer. An eye opening measurement circuit: (1) tracks a first sigma level by a first step unit depending on upper voltage levels greater than a first reference voltage level among the first voltage levels, (2) tracks a second sigma level by a second step unit depending on lower voltage levels less than a second reference voltage level among the second voltage levels, and (3) calculates a difference between the first sigma level and the second sigma level.
