Abstract

sinalização de parâmetros de dpb para fluxos de bits de vídeo multicamadas. um método de decodificação é fornecido. o método inclui receber um fluxo de bits de vídeo incluindo uma pluralidade de camadas e um conjunto de parâmetros de sequência (sps) incluindo uma flag, em que cada uma dentre a pluralidade de camadas que se referem ao sps tem um mesmo conjunto de parâmetros de (dpb) independentemente de se cada uma dentre a pluralidade de camadas é uma camada de saída ou uma camada sem saída quando a flag tiver um primeiro valor, e em que cada uma dentre a pluralidade de camadas que se referem ao sps tem um primeiro conjunto de parâmetros de dpb que se aplicam a camadas de saída e um segundo conjunto de parâmetros de dpb que se aplicam a camadas sem saída quando a flag tiver um segundo valor; e decodificar uma imagem a partir de uma dentre a pluralidade de camadas para obter uma imagem decodificada. um método de codificação correspondente também é fornecido.
