Abstract
A method of decoding a coding pattern disposed on or in a substrate. The method comprises the steps of: (a) operatively positioning an optical reader relative to a surface of the substrate; (b) capturing an image of a portion of the coding pattern; (c) sampling and decoding control symbols contained in the imaged portion to provide rregistration symbols and rsecond symbols; (d) constructing an imaged registration codeword of length rusing the registration symbols ordered in a defined sequence; (e) identifying a distinct registration codeword corresponding to the imaged registration codeword; (f) determining a registration corresponding to the identified registration codeword; (g) constructing an imaged format codeword of length m using the determined registration and some of the rsecond symbols; (h) identifying a distinct format codeword corresponding to the imaged format codeword; (i) determining a distinct format corresponding to the identified format codeword; and (j) using the determined registration and the determined format to decode data symbols sampled from the imaged portion.
