Abstract

mensagens sei de aninhamento escalável para todas as camadas. um mecanismo de codificação de vídeo é revelado. o mecanismo inclui receber um fluxo de bits em um decodificador. o fluxo de bits compreende uma ou mais camadas e uma mensagem de informações suplementares de enriquecimento (sei) de aninhamento escalável em uma unidade de camada de abstração de rede (nal) sei atual. a mensagem sei de aninhamento escalável contém mensagens sei aninhadas escaláveis e uma flag de todas as camadas (all_layers_flag) de aninhamento escalável que especifica se as mensagens sei aninhadas escaláveis se aplicam a todas as camadas que têm um identificador (id) de camada que é maior que ou igual a um id de camada da unidade sei nal atual. uma imagem codificada é decodificada a partir da uma ou mais camadas para produzir uma imagem decodificada. a imagem decodificada é encaminhada para exibição como parte de uma sequência de vídeo decodificada.
