Potentially, the multiscale aspect of compatibly extend a predictive coder to higher bandwidths and higher resolution images.

In a predictive coder, for example, the prediction is derived from the difference between the actual input frame and the reconstructed previous image.

The particular model we endorse is a combination of pyramids and predictive coders, where the multiscale attibutes fo the pyramid are combined with the efficiency of prediction.
