Abstract An apparatus for processing video signals receives an input digital video signal corresponding to a displayed image and occurring in successive samples derived at a sampling clock frequency. The input digital video signal is divided into successive groups of samples corresponding to successive intervals of time, each group being further divided into N sections of successive samples and the samples within each section corresponding to a defined area of the displayed image. The received samples are written into an addressable memory at selected write addresses and are read out from selected read addresses. The read addresses are generated so as to cause cyclically sequential read out of the N sections, with the samples being read out in the order of entry and starting from the initial samples in each of the N sections. The N sections read from the memory are supplied to respective latch circuits, the outputs of which constitute N channel signals.
