Bildprediktor

The invention relates to a predictor intended to deliver in the guise of a block of pixels of a current image a set of p target pixels of the preceding image so that each target pixel corresponds in the image to the neighbouring pixels of the current pixel shifted by a specified displacement vector. This predictor comprises a search memory, each cell of which can be addressed independently in read and write mode; three write decoders (WWD1-3) for simultaneously write addressing three cells of three segments of the memory; p read decoders (RWD1-4, RBD1-4) for simultaneously read addressing p cells of p separate sub-segments of the memory; and means of control of the write decoders such that p successive writings of data of like nature corresponding to p neighbouring points in the image are carried out in each of the p sub-segments.
