Abstract
A method of independently encoding an image with two information channels comprises generating an image which encodes a primary information channel based on brightness levels. The image is modified to encode a secondary information channel. This image modification comprises applying one of two image output values to the image portion, wherein the brightness of a modified image portion is not changed such as to change the primary information channel encoding.
