Abstract: A method and apparatus for outputting a supplementary content in a WFD is disclosed. A method for outputting a supplementary content in a WFD may comprise the steps of: after a WFD source is connected to a WFD, transmitting, by the WFD source, an RTSP-based RTSP parameter request message to a WFD sink in order to perform a capability negotiation procedure with the WFD sink; transmitting, by the WFD source, an RTSP parameter response message to the WFD sink in response to the RTSP parameter request message; and after the capability negotiation procedure is performed, transmitting, by the WFD source, a transmission stream, obtained by overlapping and multiplexing a video stream including video data having first resolution and a supplementary stream including supplementary data having second resolution, to the WFD sink, wherein a WFD discovery response frame may include second resolution-related information for determining the second resolution and an RTSP parameter response frame may include the second resolution-related information.

Abstract: A wireless device includes a memory, a display unit configured to display a first image, a wireless communication unit configured to receive a mirroring image from an external device including a mobile display unit configured to display a second image, and a processor configured to control the display unit and the wireless communication unit. The processor is configured to automatically analyze a ratio of the second image based on the received mirroring image, and display a third image having the same ratio as that of the second image on the first image according to the analysis result.

Abstract: Disclosed are a method of controlling a source device in a sink device and apparatus therefor. The present invention includes the steps of outputting the video data received from the source device to a display unit, recognizing a text from a screen corresponding to the video data outputted to the display unit, saving the recognized text to a memory to correspond to location information on the screen corresponding to the video data, receiving a voice signal, converting the received voice signal into a text, and if a specific text including at least one portion of the converted text exists in the recognized text, sending a message corresponding to a user input of selecting the specific text from the screen corresponding to the video data to the source device.
