Abstract
MÉTODO E APARELHO DE DECODIFICAÇÃO DE VÍDEO, E MEIO DE ARMAZENAMENTO LEGÍVEL POR COMPUTADOR. A presente divulgação divulga um método e aparelho de decodificação de vídeo empregando SVT com tipo de transformada adaptativa. O método compreendendo: determinar (501) o uso de SVT-V ou SVT-H para um bloco residual; determinar (504) uma posição de bloco de transformada de um bloco de transformada do bloco residual; determinar (505) um tipo de transformada do bloco de transformada, em que o tipo de transformada indica uma transformada horizontal e uma transformada vertical para o bloco de transformada, em que pelo menos uma da transformada horizontal e a transformada vertical é DST-7; e reconstruir (507) o bloco residual com base no tipo de transformada, na posição de bloco de transformada e em coeficientes de transformada do bloco de transformada. Ao empregar a solução da presente divulgação a qualidade de decodificação pode ser aprimorada.
