Abstract
sinalização de elementos de sintaxe não de nível de imagem no nível de imagem. um método implementado por um decodificador de vídeo e compreendendo: receber, pelo decodificador de vídeo, um fluxo de bits de vídeo compreendendo um indicador de rpl, em que o indicador de rpl igual a um primeiro valor especifica que sinalização de rpl está presente em um cabeçalho de imagem (ph), e em que o indicador de rpl igual a um segundo valor especifica que sinalização de rpl não está presente no ph e pode estar presente em cabeçalhos de fatia; e decodificar, pelo decodificador de vídeo usando o indicador de rpl, uma imagem codificada para obter uma imagem decodificada. um método implementado por um decodificador de vídeo e compreendendo: receber, pelo decodificador de vídeo, um fluxo de bits de vídeo compreendendo um indicador de sao, em que o indicador de sao especifica que informações de sao podem estar presentes ou não estão presentes em um ph ou especifica que informações de sao podem estar presentes ou não estão presentes em cabeçalhos de fatia; e decodificar, pelo decodificador de vídeo usando o indicador de sao, uma imagem codificada para obter uma imagem decodificada.
