Title (EN) METHOD AND DEVICE FOR PERFORMING AUDIO/VIDEO STREAMING IN WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ ET DISPOSITIF POUR EFFECTUER UNE DIFFUSION EN FLUX AUDIO/VIDÉO DANS UN SYSTÈME DE COMMUNICATION SANS FIL
(KO) 무선 통신 시스템에서 오디오/비디오 스트리밍 수행 방법 및 장치
Abstract: front page image
(EN)The specification discloses a method for performing an audio/video (A/V)streaming between at least one source device and at least one sink device in a wireless communication system, the method comprising the steps of: receiving an A/V source discovery message for detecting A/V channel related information supported in the source device from the sink device by the source device; transmitting a response to the A/V source discovery message to the sink device; receiving A/V channel related information selected by the sink device from the sink device in order to perform the A/V streaming; performing an A/V stream connecting procedure for the sink device and the A/V streaming; and transmitting the A/V stream to the sink device using A/V channel related information selected by the sink device.
(FR)L'invention concerne un procédé pour effectuer une diffusion en flux audio/vidéo (A/V) entre au moins un dispositif source et au moins un dispositif collecteur dans un système de communication sans fil, le procédé comprenant les étapes consistant à: recevoir par le dispositif source, en provenance du dispositif collecteur, un message de découverte de source A/V servant à détecter des informations relatives au canal A/V prises en charge dans le dispositif source; transmettre au dispositif collecteur une réponse au message de découverte de source A/V; recevoir, en provenance du dispositif collecteur, des informations relatives au canal A/V sélectionnées par le dispositif collecteur de manière à effectuer la diffusion en flux A/V; effectuer une procédure de connexion de flux A/V pour le dispositif collecteur et la diffusion en flux A/V; et transmettre le flux A/V au dispositif collecteur à l'aide des informations relatives au canal A/V sélectionnées par le dispositif collecteur.
(KO)본 명세서는 무선 통신 시스템에서 적어도 하나의 소스 장치(Source Device)와 적어도 하나의 싱크 장치(Sink Device) 간 A/V(Audio/Video) 스트리밍을 수행하기 위한 방법에 있어서, 소스 장치는 싱크 장치로부터 상기 소스 장치에서 지원하는 A/V 채널 관련 정보를 발견하기 위한 A/V 소스 디스커버리(Source Discovery) 메시지를 수신하는 단계; 상기 싱크 장치로 상기 A/V 소스 디스커버리 메시지에 대한 응답을 전송하는 단계; 상기 싱크 장치로부터 A/V 스트리밍을 위해 상기 싱크 장치에서 선택되는 A/V 채널 관련 정보를 수신하는 단계; 상기 싱크 장치와 A/V 스트리밍을 위한 A/V 스트림 연결 절차를 수행하는 단계; 및 상기 싱크 장치에서 선택되는 A/V 채널 관련 정보를 이용하여 상기 싱크 장치로 A/V 스트림을 전송하는 단계를 포함하는 것을 특징으로 한다.
