Abstract

A radio frequency (RF) communication system transmits information including multiple data formats. The RF communication system receives the information (102) and parses the information into a plurality of nibbles (126), each of the nibbles comprising a predetermined number of bits. The plurality of nibbles are then provided to a terminal (10) as a message (154), the message is encoded by the terminal (10), and the encoded message is transmitted to a transmitter (15) for transmission therefrom.
