Abstract: front page image
(EN)An embodiment of the present invention relates to a Wi-Fi display (WFD) service initiation method comprising the steps of: in a method for a first apparatus that supports WFD initiating a WFD service, the first apparatus transmitting a WFD discovery frame to a second apparatus; and the first apparatus transmitting a real-time streaming protocol (RTSP) M1 message, wherein the first apparatus transmits one of a provision discovery request or a session initiation request to the second apparatus before transmitting the M1 message if there is an internet protocol (IP) connection established between the first apparatus and the second apparatus when transmitting the WFD discovery frame.
(FR)Un mode de réalisation de la présente invention concerne un procédé d'initiation de service d'affichage Wi-Fi (WFD) comprenant les étapes suivantes : dans un procédé implémenté dans un premier appareil supportant le WFD, initier un service WFD, le premier appareil transmettant une trame de recherche WFD à un second appareil ; et le premier appareil transmet un message M1 de protocole de flux en temps réel (RTSP). Le premier appareil transmet une demande de recherche de fourniture ou une demande d'initiation de session au second appareil avant de transmettre le message M1, si une connexion IP est établie entre le premier appareil et le second appareil lors de la transmission de la trame de recherche WFD.
(KO)본 발명의 실시예는, WFD(Wi-Fi Display)를 지원하는 제1 장치가 WFD 서비스를 초기화하는 방법에 있어서, 제1 장치가 WFD 디스커버리에 관련된 프레임을 제2 장치로 전송하는 단계; 및 상기 제1 장치가 RTSP(Real-Time Streaming Protocol) M1 메시지를 전송하는 단계를 포함하며, 상기 WFD 디스커버리에 관련된 프레임 전송 시 상기 제1 장치와 상기 제2 장치 사이에 IP(Internet Protocol) 연결이 수립되어 있는 경우, 상기 제1 장치는 상기 M1 메시지 전송 이전에 프로비전 디스커버리 요청 또는 세션 초기화 요청 중 어느 하나를 상기 제2 장치로 전송하는, WFD 서비스 초기화 방법이다.
