Abstract
A marker encoded and provided in the side channel of an analog rendering provides digital information about the analog rendering with which it is simultaneously provided. Perceptible non-intrusive, computer-interpretable encodings, incorporated into printed, handwritten, pictorial or video communication renderings, and audible, non-intrusive, computer-perceptible encodings in audio renderings, using available side channel bandwidth in those media, allow generating or preprocessing computer-to-recognizing computer communication of a wide range of information relating to the generation and reproduction of the main channel analog information, such as error correction encoding, scan order encoding, object identification and algorithms used in generating the analog information.
