Abstract

1/1 resumo codificação de vídeo com unidades de camadas de abstração de rede que incluem múltiplas partições de imagens codificadas um codificador de vídeo gera uma unidade de camada de abstração de rede (nal) que contém uma pluralidade de partições de imagens codificadas dos dados de vídeo. o codificador de vídeo gera um fluxo de bits que inclui um valor de comprimento variável que representa um primeiro elemento de sintaxe codificado por entropia, um valor de comprimento variável que representa um segundo elemento de sintaxe codificado por entropia, e valores de comprimento fixo que representam elementos de sintaxe de deslocamento. os comprimentos de cada um dos elementos de sintaxe de deslocamento podem ser determinados com base no primeiro elemento de sintaxe. um decodificador de vídeo utiliza o primeiro elemento de sintaxe, o segundo elemento de sintaxe e os elementos de sintaxe de deslocamento ao codificar as partições de imagens codificadas.
