Abstract

"MODIFICAçãO DE SINAIS DE VìDEO PELA CONVERSãO DE NãO INTRA-IMAGENS". A invenção refere-se a um método (200) e um sistema (10) para gravar em um meio de armazenamento (26) um segmento de vídeo. O método inclui as etapas de: receber o segmento de vídeo (210), em que o segmento de vídeo contém pelo menos uma imagem de predição; e converter seletivamente a pelo menos uma imagem de predição em uma intra-imagem, substituindo-se assim a pelo menos uma imagem de predição pela intra-imagem. Em uma disposição, o segmento de vídeo pode conter pelo menos uma imagem de predição introdutória, e a etapa de converter pode incluir também decodificar seletivamente um número predeterminado das imagens de predição introdutórias de modo a se obter uma imagem de predição adequadamente decodificada (212). Além disto, o segmento de video pode conter pelo menos uma imagem de predição subseq³ente e a etapa de converter pode incluir decodificar seletivamente as imagens de predição subseq³entes (214) e recodificar seletivamente em intra-imagens as imagens de predição subseq³entes, as imagens de predição introdutórias ou uma combinação delas (216).
