Abstract

"MéTODO DE CODIFICAçãO DE QUADROS DE VìDEO, TERMINAL DO ASSINANTE, CODIFICADOR DE VìDEO, E, PROGRAMA DE COMPUTADOR EXECUTANDO O MéTODO". O método de codificação de quadros de vídeo em um sistema telecomunicação compreende as etapas de: formar um quadro de vídeo de quadros estacionários consecutivos; armazenar os dados de reconstrução de quadro de pelo menos um quadro como um quadro de referência e os dados de movimento dos blocos vizinhos codificados anteriormente; definir por meio dos dados de movimento de um ou mais blocos vizinhos codificados anteriormente os dados de movimento do bloco a ser codificado, cujo bloco vizinho é formado por meio do quadro de referência armazenado; definir os dados de reconstrução do quadro e os dados de movimento representando o bloco a ser codificado, os quais provêem uma eficiência de codificação pré-definida com uma qualidade de imagem pré-definida.
