Abstract
The invention concerns receive circuitry for extracting horizontal and vertical synchronization signals from a digital synchronization signal associated with a video signal, the digital synchronization signal having a plurality of pulses, the receive circuitry including detection circuitry arranged to determine a first value indicative of the time delay between a timing edge of a first pulse and a timing edge of a second pulse of the digital synchronization signal; and a synchronization extraction block arranged to determine that one of the plurality of pulses is a vertical synchronization pulse based on a comparison between the first value and a reference value.
