ABSTRACT:
A system for high-speed data transmission using a television signal to communicate encoded data. A multi-level encoding method is employed whereby raw data values are converted into one of a plurality of voltage levels. The encoding method allows for improved data transfer rates, conservation of bandwidth, and self-synchronization for decoding. Mock timing data signals are generated to comply with television signal standards, such as NTSC, SECAM, PAL and HDTV.
