Abstract

SINALIZAÇÃO DE PARÂMETRO DE FILTRO DE DESBLOQUEIO. Um encodificador de vídeo pode sinalizar um conjunto de valores para um ou mais parâmetros de filtro de desbloqueio em um conjunto de parâmetros de alto nível. Um decodificador de vídeo pode receber e decodificar o conjunto de valores. O encodificador de vídeo também pode encodificar um índice para o conjunto de valores em um nível inferior. O decodificador de vídeo pode decodificar o índice e, em seguida, usar o índice para determinar o valor específico do conjunto de valores para determinar o parâmetro de filtro de desbloqueio.
