ABSTRACT:
A method for encoding and transmitting video signals, the method including separating the video signals into consecutive base intervals, each base interval having a predetermined time duration; time delaying every other one of the base intervals for the predetermined time duration whereby consecutive pairs of the base intervals are available in parallel; time expanding by a factor of two each of the consecutive pairs of base intervals thereby reducing the bandwidth of the intervals by one-half; and amplitude modulating in quadrature the base intervals in the time expanded consecutive pairs of base intervals onto a carrier frequency located in a transmission band.
