Abstract

A programmable synchronizing system for selectively providing synchronizing signals at different rates, such as for incorporation in a video signal decompression system, includes an oscillator and a programmable counter. The programmable counter is conditioned to count pulses from the oscillator by alternate moduli in predetermined sequences to generate the synchronizing signals. The desired synchronization rate is effectively the average of the counter output resulting from counting by the alternate moduli.
