Abstract

"SISTEMA E MéTODO PARA CODIFICAçãO INTRAFRAME PARCIAL PARA TRANSMISSãO DE MULTIMìDIA SEM FIO". Multimídia digital inclui informação de intraframe e informação de interframe. Em adição ao envio de intraframes completos separados, que são referidos por interframes, alguns interframes (quadros 'híbridos') contêm informação de intraframe parcial, de forma que se um intraframe completo for perdido, referência a interframes pode obter pelo menos alguma informação de intraframe dos quadros híbridos.
