Abstract
A method of transmitting and receiving encoded data generated from input data comprising readable text characters (102) in a communication system having an optical character recognition element (206) and a graphic encoding element (208), the communication system also having a transmitter (114) and a receiver (116), comprises accepting (602) the input data comprising the readable text characters (102) by a facsimile input (202). The method further comprises encoding (620, 622) as character code format data the readable text characters (102) received that are recognizable by the optical character recognition element (206), and encoding (610, 612, 614) as graphic code format data the readable text characters (102) received that are not recognizable by the optical character recognition element (206). The method further comprises assembling (632) the character code format data and the graphic code format data into an output data stream, the output data stream including information that describes original sizes and positions relative to one another of the readable text characters (102).
