Abstract

método implementado por decodificador, mídia legível por computador não transitória e dispositivo de decodificação. um mecanismo de codificação de vídeo é revelado. o mecanismo inclui codificar uma imagem codificada em uma ou mais unidades de camada de abstração de rede (nal) de camada de codificação de vídeo (vcl) em um fluxo de bits. uma unidade não-vcl nal é codificada no fluxo de bits de modo que um identificador temporal (temporalid) para a unidade não-vcl nal seja restringido para ser igual a um temporalid de uma unidade de acesso (au) contendo a unidade não-vcl nal quando um tipo de unidade nal (nal_unit_type) da não-vcl nal indicar uma mensagem de informações suplementares de enriquecimento (sei). um conjunto de testes de conformidade de fluxo de bits é realizado no fluxo de bits com base na mensagem sei. o fluxo de bits é armazenado para comunicação em direção a um decodificador.
