Abstract

"CODIFICAçãO E DECODIFICAçãO GRADUáVEIS DE DADOS DE VìDEO DIGITAL ENTRELAçADOS". Trata-se de um codificador e um decodificador completamente graduáveis para vídeo entrelaçado. Um método para codificar uma seqüência entrelaçada de dados de vídeo digital decompõe a seqüência de vídeo entrelaçada (I) em primeiros (FI) e segundos (F2) campos, efetua filtragem digital (SF1) para obter sinais componentes de freqüência mais baixa (L) e de freqüência mais elevada (H) dos primeiros campos (FI) e utiliza filtragem espacio-temporal (STF) e estimativa de movimento (MEI) para gerar sinais de camada base (P, MV1) adequados para a reconstrução de uma seqüência de vídeo no modo progressivo (V1, V2) em um receptor. Vantajosamente, tanto o filtro espacio-temporal (STF) no codificador quanto o processo inverso (STS) no receptor podem efetuar graduação nas dimensões espacial e temporal. Os segundos campos (F2) são utilizados para gerar sinais de aperfeiçoamento (FF2, MV2), que permitem que um receptor reproduza uma seqüência de vídeo entrelaçada de resolução espacial e/ou temporal completa, ou graduada.
