ABSTRACT:
A clamping circuit for use in a line sequential video processor sets separate dc voltage levels for a pair of color difference signals. The respective dc levels serve to identify the sequence of the color difference signals in the line sequential signal. By first setting the voltage offset between the respective levels, the dc voltage levels for both color difference signals are later established by clamping only to every other signal. The clamping circuit includes a monostable multivibrator that generates a clamping pulse only at the onset of every other color difference signal.
