Abstract

a presente invenção se refere a um decodificador de vídeo configurado para, para um grupo de blocos de vídeo dos dados de vídeo, determinar que um número de grupos mesclados para uma pluralidade de classes é igual a um grupo mesclado; receber uma primeira marcação indicando que as informações de coeficientes de filtro para pelo menos um grupo mesclado não são codificadas nos dados de vídeo; receber, para o grupo mesclado único, uma segunda marcação, em que um primeiro valor para a segunda marcação indica que as informações de coeficientes de filtro mapeadas para o grupo mesclado único são codificadas nos dados de vídeo, e em que um segundo valor para a segunda marcação indica que as informações de coeficientes de filtro mapeadas para o grupo mesclado único são, todas, valores zero; determinar que a segunda marcação é igual ao segundo valor e determinar um ou mais filtros do conjunto de filtros usando todos os valores zero.
