Abstract
método de decodificação de vídeo, método de codificação de vídeo, e dispositivode codificação de vídeo. um método e dispositivo de decodificação de vídeo para determinar se um modo de predição de um bloco atual é um modo afim; dividir, quando o modo de predição do bloco atual for o modo afim, um bloco luma do bloco atual em uma pluralidade de blocos sub luma tendo uma forma quadrada com base em um tamanho de bloco sub predefinido; determinar um vetor de movimento médio luma para quatro blocos sub luma vizinhos entre a pluralidade de blocos sub luma, usando um vetor de movimento de um bloco sub luma superior esquerdo dos quatro blocos sub luma e um vetor de movimento de um sub luma inferior direito bloco dos quatro blocos sub luma; determinar o vetor de movimento médio luma como um vetor de movimento de um bloco de sub croma atual correspondente aos quatro blocos sub luma; e realizar predição no bloco de sub croma atual usando o vetor de movimento determinado, em um processo de codificação e decodificação de vídeo são sugeridos.
