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.Methods and apparatus for processing multimedia data that enable efficient partial decoding of encoded transformed data are described. A decoder device receives transformed coefficients, where the transformed coefficients are associated with multimedia data. The decoder device determines a set of multimedia samples to be reconstructed. In one aspect, the set of samples to be reconstructed is a subset of an array of transformed multimedia samples. The decoder device determines a set of transformed coefficients to be used to reconstruct the multimedia samples. In one aspect, the transformed coefficients are used to scale partial base images associated with the coding method used to generate the transformed coefficients resulting in reconstructed multimedia samples.
