1. Method for encoding video data, comprising the following steps:

  • obtain the digital file of an original image to be processed;

    process the image with estimation to obtain an approximation of said image, represented by motion vectors;

    calculate the difference between said original image and said approximation to obtain a residual image;

    obtain the bit plans of said residual image, represented by quadtrees;

    process said quadtrees with estimation to obtain an estimation quadtree file;

    calculate the difference between quadtrees of said residual image and quadtrees of said estimation to obtain a difference quadtree file;

    encoding quadtrees of said estimation quadtree file and said difference quadtree file; and

    output said motion vectors and data of said encoded quadtrees.
