Abstract

método e aparelho para processar dados de vídeo, e, mídias de armazenamento e de gravação legíveis por computador não transitórias. um método para processamento de vídeo inclui realizar uma conversão entre uma unidade de vídeo de um vídeo e uma representação codificada do vídeo usando pelo menos uma figura de vídeo. apenas um de um modo de codificação de subfigura ou um modo de codificação com mudança de resolução é habilitado para a unidade de vídeo. o modo de codificação de subfigura é um modo no qual a figura de vídeo é dividida em múltiplas subfiguras, e o modo de codificação com mudança de resolução é um modo no qual uma resolução da figura de vídeo é ajustada durante a conversão.
