Abstract

resumo controle de filtragem de malha sobre fronteiras entre blocos um codificador de vídeo pode ser configurado para codificar um elemento de sintaxe que indica se uma operação de filtragem de malha, tal como filtragem desbloqueadora, filtragem de malha adaptativa ou filtragem por deslocamento adaptativo a amostras, é permitida através de uma fronteira entre blocos. um primeiro valor para o elemento de sintaxe pode indicar que a filtragem de malha é permitida através da fronteira entre blocos, e um segundo valor para o primeiro elemento de sintaxe pode indicar que a filtragem de malha não é permitida através da fronteira entre blocos. se a filtragem de malha através de uma fronteira entre blocos, elementos de sintaxe adicionais podem indicar especificamente para quais fronteiras a filtragem de malha é permitida ou desautorizada.
