Abstract
A presente invenção relaciona-se a um método para decodificar um sinal de vídeo com base nas transformadas múltiplas adaptativas (AMT), o método compreendendo as etapas de: obter um índice AMT a partir do sinal de vídeo, em que o índice AMT indica qualquer uma de uma pluralidade de combinações de transformada em um grupo de configuração de transformada, e o grupo de configuração de transformada inclui a transformada discreta de seno tipo 7 (DST7) e a transformada discreta de cosseno tipo 8 (DCT 8); derivar uma combinação de transformadas correspondendo ao índice AMT, em que a combinação de transformadas consiste de uma transformada horizontal e uma transformada vertical, e inclui pelo menos uma dentre a DST-7 ou a DCT-8, realizar uma transformada inversa em um bloco atual com base na combinação de transformadas, e restaurar o sinal de vídeo usando o bloco atual transformado inversamente, em que a AMT representa um esquema de transformadas que é realizado com base em uma combinação de transformadas selecionada adaptativamente a partir de uma pluralidade de combinações de transformada.
