  • Methods and circuits using frequency shift keying modulation to transfer data over transmission lines simultaneous with television signals
    Patent number: 6189148
    Abstract: Data is transferred using frequency shift keying modulation in a frequency range that is not within a television signal frequency range used to conduct the television signal over the transmission line. Consequently, the present invention may allow the television signal and the data to be conducted on the same cabling. The frequency shift keying modulation is provided by generating a modulated data signal based on information included in the data. For example, the frequency shift keying modulation generates a modulated data signal at a first frequency when the data is equal to a logical 0 and at a second frequency when the data is equal to a logical 1.
