Abstract

"MéTODO PARA CODIFICAR E DECODIFICAR UMA INFORMAçãO DE VìDEO, CODIFICADOR PARA EXECUTAR A CODIFICAçãO DE MOVIMENTO COMPENSADO E DECODIFICADOR CORRESPONDENTE, ELEMENTO DE REDE, ESTAçãO MóVEL, E, ELEMENTO DE PROGRAMA". Método para codificar uma informação de vídeo é apresentado, onde uma peça da informação de vídeo atual é dividida em macro-blocos e um número exato de segmentações de macro-bloco disponível para segmentar um macro-bloco em blocos é definido. Em adição, para cada segmentação de macro-bloco disponível ao menos um método de predição disponível é definido, cada um dos métodos de predição produz os coeficientes de movimento de predição para os blocos dentro dos macro-blocos, resultando em um número finito exato dos pares do método-predição-segmentação-macro-bloco disponíveis. Para um macro-bloco, um dos pares do método-predição-segmentação-macro-bloco disponíveis é selecionado, e desse modo o macro-bloco é segmentado em blocos e os coeficientes de movimento de predição para os blocos dentro do macro-bloco são produzidos usando o par do método-predição-segmentação-macro-bloco selecionado. O método de decodificação correspondente, o codificador e o decodificador são também apresentados.
