    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: An electronic device includes a reception equalizer that performs, a first equalization on a first signal based on a first coefficient, and one or more second equalizations on one or more second signals based on the first coefficient, the one or more second signals being based on a second coefficient associated with one or more characteristics of a transmission equalizer of the external device, and circuitry that iteratively sends control information generated based on the first coefficient to the external device until a termination condition is satisfied with regard to the first coefficient, the control information causing the second coefficient to be increased or decreased, the iteratively sent control information causing a first absolute value of the first coefficient corresponding to a final equalization of the one or more second equalizations to become smaller than a second absolute value of the first coefficient corresponding to the first equalization.
