Abstract

The present invention involves facsimile systems that, at one or more points in the process, make use of the sign domain (also called the symbol domain; the ASCII character for "E" rather than a digitized image of a printed "E," for instance). By taking advantage of the fact that many documents are produced in sign-domain terms (on a computer word processor, for instance, rather than with a pen and ink), and that most documents, however, produced are capable of sign-domain interpretation, the invention reduces the time taken to transmit a typical document, and increases the accuracy of the reproduction at the receiving end, as well as enabling the reliable transmission of arbitrary binary data.
