Abstract
Signal processors for permitting the transparent, simultaneous transmission and reception of a volume of information in the video bandwidth is disclosed. The volume of data is selected in response to receiving a signal at a transmitter site. The signal processor in the transmitter rasterizes the volume of information at the horizontal scanning rate and modulates the volume of information with a data carrier at a non-integral multiple of the horizontal scanning rate to provide a frequency interleaved combined signal. The combined signal is transmitted during the active video portion of each video line.
