Triggering flash

    I have an analog camera that outputs a PAL signal. I'm capturing frames from
    the camera using a capture card which is all working well. The problem I
    have is getting a flash timed to the frame of the camera. Is there a way to
    get some sort of sync signal from the camera and use that to trigger the
    flash? What I was thinking was the PC could tell the flash to arm itself
    through USB or serial and the flash could then be triggered by the sync
    signal. I can do the serial or usb part and make a circuit but am not sure
    how to get the signal from the camera.

    Thanks for any replies,
