Abstract

Multi-modal sweep converter It consists of a deceleration circuit (33) to slow down the line of the video signal, and to choose to display. Return the said line A multiplexer (30) is held for selection to generate signals. Brightness or color signal to any signal that goes to the deceleration circuit Signal output From the deceleration circuit and the output signal from the multiplexer will be connected to the circuit in proportion (34), in which the circuit will combine the signals together proportionally (such as K and 1-K). The second (35), which produces a brightness signal at the output which is converted Which will be provided To choose to pass the brightness signal or color signal from the third multiplexer input circuit (36), which will produce the color signal at the output which is converted. It will be arranged to select. Through the color signal or the signal coming from the circuit into the said proportion
