Abstract
sinalização de cabeçalho de imagem em codificação de vídeo. um método de decodificação é fornecido. o método inclui receber um fluxo de bits de vídeo incluindo uma unidade de imagem (pu) que tem um cabeçalho de imagem (ph) com uma estrutura de sintaxe de ph, em que a estrutura de sintaxe de ph inclui os seguintes elementos de sintaxe comuns para todas as fatias de uma imagem codificada associada à estrutura de sintaxe de ph: uma flag de imagem não-referência, um identificador (id) de conjunto de parâmetros de imagem (pps), um bit menos significativo (lsb) de contagem de ordem de imagem (poc), uma flag de não emissão de imagens anteriores, uma poc de ponto de recuperação, e uma flag de emissão de imagem; e decodificar a imagem codificada a partir da pu para obter uma imagem decodificada.
