Abstract

The subject matter of the invention is essentially to permit an efficient coding by using the characteristic of monotonically decreasing level values, said characteristic being often satisfied in such a video coding. According to the invention, the range of values to be coded and therewith the number of code words can be limited and, for example, information about the presence of such a monotony must be transferred only block by block.
