Abstract
Apparatus for selecting a block of data in a previous frame to be used as a predicted block for a given block in a current frame in a system that reduces the bit rate by codifying the difference between the predicted block and the given block in a given manner by deriving the differences between the given block in the current frame and a plurality of blocks in the previous frame and selecting as the predicted block that block for which the codification of its differences with the given block requires the least number of bits. The apparatus can also select a predicted block from a number of blocks selected in accordance with ABD or SBD techniques.
