Abstract

RESTRIÇÕES GERAIS DE ELEMENTOS DE SINTAXE PARA CODIFICAÇÃO DE VÍDEO. Um exemplo de método inclui decodificar, a partir de um fluxo de bits de vídeo codificados, um primeiro elemento de sintaxe que especifica uma restrição para um segundo elemento de sintaxe que especifica se informações de imagem secundária estão ou não presentes no fluxo de bits de vídeo codificados e se é permitido ou não mais que uma imagem secundária estar presente no fluxo de bits de vídeo codificados; e decodificar, com base na restrição especificada pelo primeiro elemento de sintaxe, o segundo elemento de sintaxe.
