Abstract

De acuerdo con un aspecto de la presente invencion, se proporciona un metodo y aparato en el cual son codificados los datos de entrada (por ejemplo, datos de entrada de video), de acuerdo con un primer estandar de codificacion (por ejemplo, MPEG-4) para generar datos codificados. Los datos de entrada son codificados tambien basados en una reconstruccion de los datos de entrada para generar informacion lateral codificada asociada con los datos de entrada. Los datos codificados son transmitidos a un destino (por ejemplo, un subsistema de descodificacion) por un primer canal y la informacion lateral codificada es transmitida al destino por un segundo canal. Los datos codificados y la informacion lateral codificada son descodificados y combinados en el destino para generar los datos de salida.
