Abstract
A video processing system is disclosed having a store (1) into which video signals, in the form of a sequence of pixels, are written into and read out of in response to common fixed clocking pulses, although the input video signal is synchronized independently of the output video signal. The phase of the pixels at the input to the store, and also the phase of the line and field synchronizing pulses, is adjusted to correct sub pixel phase error between input and output so that the common pixel clocking pulses can be used thereby substantially reducing cross talk between the input and output signals.
