Abstract

derivação de informações de unidade de nal de fim de sequência para fluxos de bits com múltiplas camadas um aparelho para codificar informações de vídeo de acordo com certos aspectos, o qual inclui uma memória e um processador. a memória é configurada para armazenar informações de vídeo associadas a uma ou mais camadas. o processador é configurado para codificar uma unidade de acesso (au) atual em um fluxo de bits que inclui uma pluralidade de camadas, sendo que a pluralidade de camadas inclui uma camada de referência e pelo menos uma camada de melhoria correspondente. o processador é configurado adicionalmente para codificar uma primeira unidade de camada de abstração de rede (nal) de fim de sequência (eos) associada à camada de referência na au atual, sendo que a primeira unidade de nal de eos tem o mesmo identificador de camada (id) que a camada de referência. o processador também é configurado para codificar uma segunda unidade de nal de eos associada à camada de melhoria na au atual, sendo que a segunda unidade de nal de eos tem o mesmo id de camada que a camada de melhoria.
