Abstract
A method provides greater reduction in the throughput rate and, at the same time, greater fidelity to the configuration of an HD source image. The method is applied to a multiprocessing system wherein, within the picture or picture image blocks, 'neutral' processing mode picture elements are determined, namely picture elements capable of accepting, without discrimination, at least two distinct sub-sampling processing modes; and it is chosen to associate, with each of the neutral processing mode picture elements, the one of the neutral processing modes that enables an optimal reduction in the throughput rate of the assistance data.
