Abstract

resumo “definição de unidade de decodificação expandida”. um dispositivo de codificação de vídeo, tal como um codificador de vídeo ou um decodificador de vídeo, pode ser configurado para decodificar uma duração entre um tempo de remoção de buffer de imagem codificada (cpb) de uma primeira unidade de decodificação (du) em uma unidade de acesso (au) e o tempo de remoção cpb de uma segunda du, onde a primeira du compreende uma unidade de camada de abstração de rede (nal) da camada de codificação de não vídeo (vcl) com nal_unit_type igual a unspec0, eos_nut, eob_nut, na faixa de rsv_nvcl44 a rsv_nvcl47 ou na faixa de unspec48 a unspec63. o decodificador de vídeo determina um tempo de remoção da primeira du com base pelo menos em parte na duração decodificada e decodifica os dados de vídeo da primeira du com base pelo menos em parte no tempo de remoção. 1/1
