ABSTRACT:
A data communication system in which video data is digitized, compacted, and transmitted by a frequency modulated radio station having a subsidiary communication authorization. The data is broadcast on a subcarrier channel to a radio receiver, which is connected to a microcomputer. This microcomputer generates a visual graphic display on a screen, and performs various other functions, such as error checking and permitting the user to alter the display. One application of the invention is real time monitoring of visual information by a remote receiving station. Furthermore, the invention may include a receiver that is turnable, thereby providing data to a mobile receiving station, such as an airplane. Although the invention is especially useful for monitoring weather information, it is adaptable for use with any visual graphics data that is desired to be transmitted via FM subcarrier frequencies.
