Abstract
PREVENÇÃO DE ERRO DE SPS EM EXTRAÇÃO DE SUBFLUXO DE BITS. Um mecanismo de codificação de vídeo é revelado. O mecanismo inclui codificar uma sequência de vídeo de camada codificada (CLVS) para uma camada em um fluxo de bits. Um conjunto de parâmetros de sequência (SPS) referido pela CLVS é, também, codificado no fluxo de bits. O SPS está restringido a ter um valor de identificador de camada de cabeçalho de unidade de camada de abstração de rede (NAL) (nuh_layer_id) igual a um valor de nuh_layer_id da CLVS quando a camada não usar predição de camada inter. O fluxo de bits é armazenado para comunicação em direção a um decodificador.
