Abstract

resumo “tempos de chegada e remoção nominal de buffer de imagem codificada na codificação de vídeo”. um dispositivo de codificação de vídeo, tal decodificador de vídeo podendo ser configurado para derivar pelo menos um dentre um tempo de chegada ao buffer de imagem codificada (cpb) e um tempo de remoção nominal para uma unidade de acesso (au) em ambos um nível de unidade de acesso e um nível de sub-imagem independentemente de um valor de um elemento de sintaxe que define se uma unidade de decodificação (du) é toda a au. o dispositivo de codificação de vídeo pode ser adicionalmente configurado para determinar um tempo de remoção da au com base pelo menos em parte em um dentre um tempo de chegada ao cpb e um tempo de remoção nominal do cpb e para decodificar os dados de vídeo da au com base pelo menos em parte no tempo de remoção.
