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: Proposed are a method and a device for multiple control of an IoT controlee device on the basis of C2C account linkage in a wireless LAN system in a smart home environment. Specifically, a first control device connects to a first cloud on the basis of a first account. A first control device receives commissioning information of a second control device for the controlee device on the basis of a connection between the first cloud and a second cloud. The first control device adds commissioning to the controlee device on the basis of the commissioning information. The second control device is connected to the second cloud on the basis of a second account. The first account and the second account are linked with each other.

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.
