    Abstract: The present specification may provide a method for forming, by a searcher terminal, an application service platform session with an advertiser terminal in a wireless communication system. The method for forming an application service platform session may comprise the steps of: performing discovery for the advertiser terminal and a first service; and forming an ASP session for the first service by performing connection with the advertiser terminal on the basis of a result of the performed discovery, wherein the discovery and the connection may be performed through at least one of multiple interfaces supported by application service platforms of the searcher terminal and the advertiser terminal when the searcher terminal and the advertiser terminal are first type terminals, and the discovery and the connection may be performed through a Wi-Fi direct interface when one of the searcher terminal and the advertiser terminal is the first type terminal and the other is a second type terminal.

    Abstract: Provided are a method and an apparatus for transmitting metadata in a WFD. More particularly, a WFD source transmits, to a WFD sink, a first transmission stream in which an audio stream and a video stream are superimposed and multiplexed. The WFD source receives, from the WFD sink, a first RTSP request message for requesting transmission of metadata for audio data and video data during the transmission of the first transmission stream. The WFD source transmits, to the WFD sink, a first RTSP response message in response to the first RTSP request message during the transmission of the first transmission stream. The WFD source transmits, to the WFD sink, a metadata stream including the metadata and a second transmission stream in which the audio stream and the video stream are superimposed and multiplexed.

    Abstract: Disclosed are a method for data communication between NAN devices, and a NAN device for performing data communication. The method for data communication between the NAN devices comprises the steps of: receiving a service discovery frame from a second NAN device by a first NAN device; transmitting a TIM element to a second NAN device by the first NAN device having received the service discovery frame and being triggered by a user action, wherein the TIM element includes information related to data buffered with respect to the second NAN device; performing, by the first NAN device, an authentication procedure and an association procedure with the second NAN device on the basis of a request of the second NAN device having received the TIM element; transmitting a falling frame from the second NAN device by the first NAN device; and transmitting, by the first NAN device, the data buffered with respect to the second NAN device, to the second NAN device in response to the falling frame.

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