AbstractSignal 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 receiver selects a forward channel transmitting the combined signal responsive to a control signal and extracts the data portion of the transmitted combined signal.
