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), a pu incluindo uma unidade de camada de abstração de rede (nal) de cabeçalho de imagem (ph) que tem um tipo de unidade nal de cabeçalho de imagem (ph_nut) e uma unidade nal de camada de codificação de vídeo (vcl) associada, o ph_nut significando que um identificador (id) de camada da unidade ph nal é igual a um id de camada da unidade nal de camada de codificação de vídeo (vcl) associada e um id temporal da unidade ph nal é igual a um id temporal da pu; e decodificar uma imagem codificada a partir da pu para obter uma imagem decodificada.
