Abstract

"MéTODO E APARELHO PARA ESTIMATIVA DE PROGNóSTICO PONDERADO UTILIZANDO UM DIFERENCIAL DE QUADRO DESLOCADO". Trata-se de um codificador de vídeo (200, 300) e dos métodos correspondentes (600, 700) que são proporcionados para estimativa de prognóstico ponderado utilizando uma diferença ou diferencial de quadro deslocado, o codificador incorporando um método (700) para receber (712) um bloco de imagem substancialmente não compactado, designar (714) um fator de ponderação para o bloco de imagem correspondendo a uma imagem de referência particular possuindo um índice correspondente, calcular (716) vetores de movimento correspondendo à diferença entre o bloco de imagem e a imagem de referência particular, compensar o movimento (718) da imagem de referência particular em correspondência com os vetores de movimento, multiplicar (720) a imagem de referência com movimento compensado pelo fator de ponderação designado para formar uma imagem de referência com movimento compensado ponderada, subtrair (722)a imagem de referência com movimento compensado ponderada do bloco de imagem substancialmente não compactado e codificar (724) um sinal indicativo da diferença entre o bloco de imagem substancialmente não compactado e a imagem de referência com movimento compensado ponderada junto com o índice correspondente da imagem de referência particular.
