Abstract

uso genérico de mensagens sei hevc para codecs de múltiplas camadas em um exemplo, um método de codificação de dados de vídeo inclui a codificação de uma ou mais unidades de camada de abstração de rede (nal) da camada de codificação de não vídeo (vcl) de uma camada de uma sequência de bits de múltiplas camadas de dados de vídeo, onde uma ou mais unidades nal não vcl contêm uma mensagem sei possuindo um tipo de carga útil sei. o método também inclui a determinação de um ou mais valores de sintaxe da sequência de bits de múltiplas camadas à qual a mensagem sei se aplica com base no tipo de carga útil sei.
