ABSTRACT:
Methods and apparatus for detecting movement in a composite television signal. A first difference signal is generated according to the difference between an Nthframe and an N−2thframe of a composite television signal. A second difference signal is generated by Y/C separation of an Nthframe and the N−1thframe of the composite television signal. A smooth signal is generated according to the smoothness of the Nthframe and the N−1thframe of the composite television signal. The first and second difference signals are output selectively according to the smooth signal.
