Abstract:
A method for encoding color graphics and text messages for display on a color graphic screen into a commercial radio transmission, comprising the steps of:a) storing into memory a text message and graphics bits, said graphics bits indicating the size, style, and color of said text message; b) generating a subcarrier of the carrier frequency of said radio transmission; c) segmenting said text message into text segments and along with said graphics bits into blocks of binary data; d) assembling said blocks into groups of four blocks each, said groups comprising a data stream for transmission; e) encoding said groups with control bits, said control bits indicating the beginning and end of said text segments, and the number and location in the data stream of said text segments that comprise a complete message; f) modulating said subcarrier with said data stream; and g) transmitting said modulated subcarrier as part of said carrier frequency for receipt and display on a radio receiver.
