Abstract

A selective call communication system (10) has a scanner (14) for retrieving information from a source document (26). The source document (26) includes a region of interest (42) formatted in at least two format regions (50, 52, 54). The at least two format regions (50, 52, 54) include a first format region (50, 52) designated for a first type information, and a second format region (54) designated for a second type information. The scanner (14) further includes an encoder (708) for encoding and compressing the information; and a modem (710), coupled to the encoder (708), for transferring the information to a selective call terminal (28). The selective call terminal (28) has a receiver (202) for receiving the information; and a processor (20), coupled to the receiver (202), for processing the information. The processor (20) further comprises a first encoder (214) for encoding and compressing the first type information according to a first encoding and compression technique; and a second encoder (224) for encoding and compressing the second type information according to a second encoding and compression technique. A transmitter (30), coupled to the processor (20), transmits the information being processed to an at least one selective call receiver (40).
