Abstract

aninhamento escalável para mensagens sei de sufixo. um mecanismo de codificação de vídeo é revelado. o mecanismo inclui codificar uma ou mais imagens codificadas em um fluxo de bits. uma unidade de camada de abstração de rede (nal) de informações suplementares de enriquecimento (sei) com um tipo de unidade nal (nal_unit_type) igual a um tipo de unidade sei nal de sufixo também é codificado no fluxo de bits. a unidade sei nal contém uma mensagem sei de aninhamento escalável. um conjunto de testes de conformidade de fluxo de bits é realizado no fluxo de bits com base na mensagem sei de aninhamento escalável. o fluxo de bits é armazenado para comunicação em direção a um decodificador.
