Abstract

"MéTODO, EQUIPAMENTO, E SISTEMA PARA ENCODIFICAR E DECODIFICAR INFORMAçõES SECUNDáRIAS PARA TRANSMISSãO DE MULTIMìDIA". De acordo com um aspecto da presente invenção, são providos um método e equipamento, no qual dados de entrada (por exemplo, dados de vídeo de entrada) são encodificados de acordo com um primeiro padrão de codificação (por exemplo, MPEG-4) para gerar dados encodificados. Os dados de entrada também são encodificados com base em uma reconstrução dos dados de entrada para gerar informação secundária encodificada associada aos dados de entrada. Os dados encodificados são transmitidos para um destino (por exemplo, um subsistema de decodificação) através de um primeiro canal e a informação secundária encodificada é transmitida para o destino através de um segundo canal. Os dados encodificados e a informação secundária encodificada são decodificados e combinados no destino para gerar dados de saída.
