Abstract
An encoder accepts an N byte set of values for each of a plurality of image components, with N being greater than one and, for each N byte set of values, identifies a compressed symbol length, K, wherein K is the smallest integer such that the difference between any two adjacent bytes is expressible in K bits or less, outputs an indication of K and outputs a K bit difference between the byte and an immediately prior byte, for each byte in the set.
