A data compression technique is described for use in systems employing frequency separation, such as wavelet separation, in which the sub bands (0 to 9) have different numbers of frequency component values therein. The sub bands are scanned to form a stream of data for feeding to an entropy encoder (30) in an order in which a number of samples from each sub band are taken in turn, that number being proportional to how many frequency component values are in the particular sub band. <IMAGE>
