Abstract: front page image
(EN)A method for concealing frame errors comprises: a step of predicting a parameter by performing a regression analysis for each group, for a plurality of groups of a plurality of bands of an error frame; and a step of concealing errors of the error frame using the parameter predicted for each group.
(FR)L'invention concerne un procédé de dissimulation d'erreurs de trame, lequel procédé comprend : une étape consistant à prédire un paramètre par réalisation d'une analyse de régression pour chaque groupe, pour une pluralité de groupes d'une pluralité de bandes d'une trame d'erreur ; et une étape consistant à dissimuler des erreurs de la trame d'erreur à l'aide du paramètre prédit pour chaque groupe.
(KO)프레임 에러 은닉방법은 에러 프레임을 이루는 제1 복수개의 대역들로부터 구성된 복수개의 그룹에 대하여, 그룹 단위로 회귀분석을 수행하여 파라미터를 예측하는 단계, 및 그룹별로 예측된 파라미터를 이용하여 상기 에러 프레임의 에러를 은닉하는 단계를 포함한다.
