Abstract

INFERÊNCIA APERFEIÇOADA DE NOOUTPUTOFPRIORPICSFLAG EM CODIFICAÇÃO DE VÍDEO. Um aparelho para codificar informação de vídeo de acordo com certos aspectos inclui um processador configurado para determinar um valor de um indicador associado com uma imagem atual de uma camada atual a ser decodificada, o indicador indicando se as imagens em um armazenador temporário de imagens decodificadas (DPB) devem ser produzidas, em que a imagem atual é uma imagem de ponto de acesso aleatório intra (IRAP) que inicia uma nova sequência de vídeo codificado (CVS) e em que a determinação do valor do indicador se baseia em ao menos um de: (1) o formato de croma da imagem atual e o formato de croma da imagem precedente, (2) a profundidade de bit das amostras de luma da imagem atual e a profundidade de bit das amostras de luma da imagem precedente, ou (3) a profundidade de bit das amostras de croma da imagem atual e a profundidade de bit das amostras de croma da imagem precedente.
