Abstract
Movement detection in a PAL television signal is effected on that portion of the television signal which is located within the chrominance signal band. This portion (obtained via 3) is demodulated into color difference signals (11, 13) which are added (29) and subtracted (27). The subtracted signal is delayed for one picture period and combined (39) with the added signal. Then the absolute value is produced (45), so that a signal is obtained which only reports movement and does not interpret crosstalk from the luminance signal of a still picture to the chrominance signal as movement.
