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