Abstract

1 / 1 resumo “dispositivo e mã‰todo de codificaã‡ãƒo de imagem” a fim de resolver um problema no qual processamento de exibiã§ã£o se torna complicado em um dispositivo de exibiã§ã£o, um dispositivo de codificaã§ã£o de imagem ã© provido com: um meio de codificaã§ã£o que codifica um primeiro campo de um quadro especã­fico como uma intraimagem parada que ã© prevista usando apenas intraprevisã£o, e que codifica o primeiro campo do quadro especã­fico, um segundo campo do quadro especã­fico, uma imagem parada que ã© codificada depois do primeiro campo do quadro especã­fico e exibida antes do primeiro campo do quadro especã­fico, e uma imagem parada que ã© codificada e exibida depois do primeiro campo do quadro especã­fico nesta ordem; e um meio de multiplexaã§ã£o que multiplexa um fluxo contã­nuo de bits com informaã§ã£o que indica que o primeiro campo do quadro especã­fico ã© uma imagem parada que torna possã­vel iniciar a decodificaã§ã£o a partir de um ponto intermediã¡rio no fluxo contã­nuo de bits.
