Abstract
Signal processors for permitting the transparent reception of a data signal in the video bandwidth of a cable television system is disclosed. The received signal has video and data components that are frequency interleaved in the video bandwidth in the active video intervals. The data signal is modulated with a carrier at a non-integral multiple of the horizontal scanning rate of the video signal. The receiver selects a forward channel transmitting the combined signal responsive to a control signal and extracts the data portion of the transmitted combined signal.
