摘要：
In a video signal processing system apparatus for differentiating between video field types includes circuitry for measuring an interval between a vertical signal component and a predetermined transition of a horizontal signal component. Measured values from successive fields are compared to provide a signal related to the respective field type, e.g., odd/even.
