Abstract
PURPOSE: To divide the high-quality television signal into the non-wide band signals of two channels via the memory element to which the memory capacity equivalent to one line is sufficient and then to transfer these divided signals with the signal process carried out in accordance with the property of each signal.
CONSTITUTION: The high-quality input TV signal sent from input terminal 1 along with the sampling signal from input terminal 2 are led to sampling circuit 1 to carry out the sampling of the high-quality TV signals, and the sampling output is led directly to Hadamard conversion circuit 3 and also led to circuit 3 with a delay of one line applied via delay circuit 2. Conversiin output signal H1 and H2 whose time axes are extended each are introduced to emphasis circuit 4 and 5 each from circuit 3 and then furthermore transmitted through the transmission line transmitting the standard TV signals and via FM modulator 6 and 7. At the receiver side, the opposite operation to the above is given to restore the original high-quality TV signals.
