ABSTRACT:
Device for processing digital signals constituted by image blocks and hierarchically arranged types of data. This device comprises an addressable memory (40) for storing said signals, a circuit (10) for counting, per section, the number of bits corresponding in these signals to each type of data, a circuit (20) for assigning, to each of the image sections and in accordance with a given proportion, the number of bits to be transmitted in channels of different priorities, and at the output of said circuits a control circuit (30) for redistributing the bits for each of the sections and in packets of given lengths comprising at least the first bits of a block and possibly the leftover bits of the other blocks. The invention also relates to the device for inverse processing at the receiver end.
