Abstract: A method and a device for transmitting metadata in a WFD are provided. Particularly, a WFD source forms a WFD frame including a WFD header and metadata. The WFD source transmits, to a WFD sink, a packet stream created by packetizing a metadata stream including the WFD frame. The WFD header includes a metadata structure field and a metadata update indicator. The metadata structure field indicates whether the metadata has a video metadata structure or an audio metadata structure. The metadata update indicator indicates that previous metadata is updated such that all of the previous metadata is replaced with new metadata, or that the previous metadata is incrementally updated together with updated metadata.

Abstract: The present specification may provide a method for performing data exchange by NAN terminal in a wireless communication system. In this instance, the method in which the NAN terminal performs data exchange may comprises the steps of: discovering a first service by a first NAN terminal using at least one of a publish message and a subscribe message; transmitting a data request message associated with the discovered first service to a second NAN terminal by the first NAN terminal; receiving a data response message from the second NAN terminal by the first NAN terminal; and performing data exchange relating to the first service with the second NAN terminal by the first NAN terminal. In this case, the data request message may be transmitted on the basis of a data request method called by the first NAN terminal, and service protocol type information and port number information, which are returned as a return value, may be included in the data request message and may be transmitted on the basis of the data request method.

Abstract: A method and an apparatus for switching an input character in a WFD are disclosed. The method for switching an input character in a WFD comprises the steps of: transmitting, by a first WFD device, a character switch capability parameter to a second WFD device through a UIBC capability negotiation process with the second WFD device; transmitting, by the first WFD device, a first character switch establishment parameter to the second WFD device through a UIBC capability UIBC establishment process so as to establish the first character outputted onto each screen of the first WFD device and the second WFD device; transmitting, by the first WFD device, a key code for a character switch button through a UIBC to the second WFD device through a user input device of the first WFD device; and transmitting, by the first WFD device, a second character switch establishment parameter to the second WFD device through a UIBC re-establishment process so as to switch, to the second character, the first character outputted onto each screen of the first WFD device and the second WFD device.

Abstract: The present specification relates to a method for performing service discovery by a first terminal in a wireless communication system. Here, the method for performing service discovery by a first terminal may comprise the steps of: performing a service discovery procedure with a second terminal; and establishing a session connection with the second terminal, wherein the service discovery procedure may be performed through an mDNS on the basis of an ASP. In addition, the service discovery procedure may comprise the steps of: exchanging PTR query messages on the basis of the mDNS; and exchanging SRV and TXT query messages on the basis of the mDNS, wherein the TXT record of the SRV and TXT query message may essentially include advertisement ID information for the service.
