Abstract

PREVENÇÃO DE SINALIZAÇÃO REDUNDANTE EM FLUXOS DE BITS DE VÍDEO DE MÚLTIPLAS CAMADAS. Um método de decodificação é fornecido. O método inclui receber um subfluxo de bits tendo um conjunto de parâmetros de sequência (SPS) com uma estrutura de sintaxe perfil tier nível (PTL) para um conjunto de camadas de saída (OLS) com apenas uma camada; definir um número de camadas no OLS igual a um com base no OLS tendo a apenas uma camada; obter a estrutura de sintaxe PTL para o OLS com a uma camada a partir do SPS quando o número de camadas no OLS tiver sido definido igual a um; e decodificar uma imagem a partir da apenas uma camada usando a estrutura de sintaxe PTL para obter uma imagem decodificada. Um método de codificação correspondente também é fornecido.
