Abstract

MÉTODO DE PROCESSAMENTO DE SINAL DE VÍDEO E DISPOSITIVO PARA O MESMO. Um dispositivo de decodificação de sinal de vídeo compreende um processador, em que: o processador decodifica uma sintaxe de carga útil de sequência de bytes brutos (RBSP) do conjunto de parâmetros de sequência (SPS) incluída em um fluxo de bits de um sinal de vídeo, e decodifica o fluxo de bits com base no resultado de decodificação da sintaxe de RBSP de SPS; a sintaxe de RBSP de SPS inclui um primeiro elemento de sintaxe relacionado ao número de uma ou mais subimagens configurando uma imagem, e um segundo elemento de sintaxe indicando se deve processar um limite das uma ou mais subimagens como um limite de uma imagem com base no primeiro elemento de sintaxe; e o segundo elemento de sintaxe é analisado apenas quando o número das uma ou mais subimagens é dois ou mais.
