Abstract: The present invention relates to a method for a NAN proxy client transitioning a state in a wireless communication system. Here, the method for a NAN proxy client transitioning a state may comprise the steps of: the NAN proxy client transitioning, to a NAN proxy server, a request message requesting the escrowing of a proxy service; receiving a response message from the NAN proxy server; performing registration to the NAN proxy server on the basis of the response message; and the state of the NAN proxy client transitioning. Here, if the registration to the NAN proxy server is performed, the state of the NAN proxy client can be transitioned to a first state.

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.
