Abstract

codificação de indicador de bloco codificado um codificador de vídeo gera uma sequência de bits que inclui um quadtree residual (rqt) para uma unidade de codificação (cu). a cu é maior do que um tamanho máximo permitido de unidade de transformação (tu) e a rqt inclui uma hierarquia de nós. um nó raiz da rqt corresponde à cu como um todo e nós folha da rqt correspondem às tus da cu. o nó raiz é associado com um indicador de bloco codificado (cbf) para um componente de crominância. o cbf para o componente de crominância indica se qualquer uma das tus da cu são associadas com um bloco de coeficiente significante que é baseado em amostras do componente de crominância em particular. um decodificador de vídeo recebe a sequência de bits e determina, com base no cbf, se os blocos de coeficiente associados com as tus que correspondem aos nós folha incluem coeficientes diferentes de zero.
