Abstract:
(EN) A method for regulating a playing delay comprises the steps of: regulating a playing delay surplus on the basis of a difference in value between a first playing delay obtained by a first method and a second playing delay obtained by a second method, and determining an adaptation type of a current frame according to whether a previous frame is an active frame; and modifying a time scale transformation according to an adaptation method determined by the comparison result of the first playing delay and the second playing delay and the comparison result of a target delay and the first playing delay, if the determined adaptation type is a signal-based adaptation.
(FR) L'invention concerne un procédé pour réguler un retard de lecture, lequel procédé comprend les étapes consistant à : réguler un surplus de retard de lecture sur la base d'une différence de valeur entre un premier retard de lecture obtenu par un premier procédé et un second retard de lecture obtenu par un second procédé, et déterminer un type d'adaptation d'une trame courante selon le point de savoir si une trame précédente est ou non une trame active; et modifier une transformation d'échelle de temps selon un procédé d'adaptation déterminé par le résultat de comparaison du premier retard de lecture et du second retard de lecture et le résultat de comparaison d'un retard cible et du premier retard de lecture, si le type d'adaptation déterminé est une adaptation basée sur un signal.
(KO) 재생지연 조절방법은 제1 방식으로 얻어진 제1 재생지연과 제2 방식으로 얻어진 제2 재생지연간의 차이값에 근거하여 재생지연 여분을 조절하고, 이전 프레임이 액티브 프레임인지에 따라서 현재 프레임의 적응화 타입을 결정하는 단계, 및 상기 결정된 적응화 타입이 신호 기반 적응화인 경우, 상기 제1 재생지연과 상기 제2 재생지연의 비교결과와 목표지연과 상기 제1 재생지연의 비교결과에 따라 결정된 적응화 방식에 따라서 시간축 변형을 수행하는 단계를 포함한다.
