Abstract
A frame of a video signal, wherein the frame is divided into non-overlapping blocks of M.times.N pixels, M and N being positive integers, respectively, is encoded by: arranging the blocks into groups of P.times.Q blocks, P and Q being positive integers, respectively; transforming each of the P.times.Q blocks in a group into a set of M.times.N transform coefficients by using a predetermined transform method, to thereby provide P.times.Q sets of M.times.N transform coefficients for the group, the transform coefficients in a set representing different frequency components; rearranging the P.times.Q sets of M.times.N transform coefficients to generate M.times.N sets of P.times.Q rearranged coefficients, the rearranged coefficients in a set being of an identical frequency component; and setting M.times.N sets of P.times.Q rearranged coefficients as encoded data for the group of P.times.Q block.
