Abstract: front page image
(EN)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.
(FR)L’invention concerne un procédé et un appareil pour délivrer un contenu supplémentaire à partir d’un WFD. Le procédé pour délivrer un contenu supplémentaire à partir d’un WFD peut comprendre les étapes consistant : après qu’une source WFD est connectée à un WFD, à transmettre, par la source WFD, un message de requête de paramètre RTSP sur la base d’un RTSP à un WFD récepteur de façon à réaliser une procédure de négociation de capacité avec le WFD récepteur ; à transmettre, par le WFD source, un message de réponse de paramètre de RTSP au WFD récepteur en réponse au message de requête de paramètre de RTSP ; et après réalisation de la procédure de négociation de capacité, à transmettre, par le WFD source, un flux de transmission, obtenu par superposition et multiplexage d’un flux vidéo comprenant des données vidéo ayant une première résolution et d’un flux supplémentaire ayant des données supplémentaires ayant une seconde résolution, au WFD récepteur, une trame de réponse de découverte de WFD comprenant des informations associées à la seconde résolution pour déterminer la seconde résolution, et une trame de réponse de paramètre de RTSP comprenant les informations associées à la seconde résolution.
(KO)WFD에서 보조 컨텐츠를 출력하는 방법 및 장치가 개시되어 있다. WFD에서 보조 컨텐츠를 출력하는 방법은 WFD 소스가 WFD 연결 이후, WFD 싱크와 능력 협상 절차를 위해 RTSP을 기반으로 한 RTSP 파라메터 요청 메시지를 WFD 싱크로 전송하는 단계, WFD 소스가 RTSP 파라메터 요청 메시지에 대한 응답으로 RTSP 파라메터 응답 메시지를 WFD 싱크로 전송하는 단계와 WFD 소스가 능력 협상 절차 이후, 제1 해상도의 비디오 데이터를 포함하는 비디오 스트림, 제2 해상도의 보조 데이터를 포함하는 보조 스트림을 중첩 다중화한 전송 스트림을 WFD 싱크로 전송하는 단계를 포함할 수 있되 WFD 탐색 응답 프레임은 제2 해상도의 결정을 위한 제2 해상도 관련 정보를 포함하고, RTSP 파라메터 응답 프레임은 제2 해상도 관련 정보를 포함할 수 있다.
