IPC: H04N9/64
Filed: 1982-01-21
Abstract: PURPOSE:To perform an automatic switch between the black/white and color pictures, by displaying a color or balck/white video in response to the detected potential at a prescribed section of a back porch of the luminance signal of a color input signal. CONSTITUTION:The input video signal is clamped 1, and its DC potential is fixed. Then the back porch of a synchronizing signal is sampled by a sample holding circuit 2 and then smoothed 3. In this case, if a TCM signal is applied as an input, the absolute level of the pedestal is fixed at 0V by a clamping circuit 1 to obtain +0.35V. In case a black/white TV siganl is applied as an input, the smoothed output is set at 0V. This smoothed output is compared 4 with the reference voltage 5, and a switch 8 is driven by the output of comparison. As a result, no color signal is delivered when a black/white signal is supplied, and a base band color signal is delivered via a color processing circuit 7 when the TCM signal is supplied.
