Abstract

um aparelho para decodificar dados de vídeo inclui uma memória configurada para armazenar pelo menos uma parte de um fluxo de bits de dados de vídeo de várias camadas e um ou mais processadores configurados para receber uma primeira unidade de camada de abstração de rede (nal) de delimitador de unidade de acesso (aud) para uma primeira unidade de acesso, no qual o identificador de camada para a primeira unidade nal aud é igual a zero; receber uma segunda unidade nal aud para a primeira unidade de acesso, no qual o identificador de camada para a segunda unidade nal aud é maior que zero; e decodificar a primeira unidade de acesso.
