Abstract

"MéTODO E APARELHO DE CODIFICAçãO/DECODIFICAçãO DE VìDEO". A presente invenção refere-se a um aparelho de codificação de vídeo que compreende uma (um) memória de quadro/gerador de imagem preditiva 108 que tem um primeiro modo preditivo para a geração de um sinal de imagem preditiva 212 pela seleção de uma combinação dentre uma pluralidade de combinações de um número de imagem de referência e uma pluralidade de parâmetros preditivos, e um segundo modo preditivo para a geração de um sinal de imagem preditiva de acordo com um parâmetro preditivo computado com base em números de imagem de referência de uma pluralidade de imagens de referência e uma distância de imagem a imagem e um codificador de comprimento variável 111 para selecionar um dentre o primeiro e o segundo modos de predição pelo número de imagens de referência, e codificar uma informação de coeficiente de transformação ortogonal 210 concernente a um sinal de erro preditivo de um sinal de imagem preditiva 212 com respeito ao sinal de vídeo de entrada 100, uma informação de modo 213 indicando um modo de codificação, uma informação de vetor de movimento 214 e uma combinação de número de imagem de referência selecionado com a informação de índice de parâmetro preditivo 215 indicando uma combinação de informação de imagem de referência selecionada 213.
