Abstract

Se describen método y aparatos para procesar datos de multimedia que posibilitan la decodificacion parcial eficaz de datos transformados codificados. Un dispositivo decodificador recibe coeficientes transformados, donde los coeficientes transformados están asociados con datos de multimedia. El dispositivo decodificador determina un conjunto de muestras de multimedia para ser reconstruidos. En un aspecto, el conjunto de muestras a ser reconstruidos es un subconjunto de una matriz de muestras de multimedia transformadas. El dispositivo decodificador determina un conjunto de coeficientes transformados para ser utilizados para reconstruir las muestras de multimedia. En un aspecto, los coeficientes transformados son utilizados para escalar imágenes en base parcial asociados con el método de codificacion utilizado para generar los coeficientes transformados resultando en muestras de multimedia reconstruidas.
