So, with no video, if there's a light, we use the light to determine if the shot is good. If there's no light, then it's the horn.

With video, if we can see the clock, then the clock determines if it's good. If we can't see the clock, then the red light is used. If there's no light, then we listen for the horn on the tape.

Right?

I think that's right, but only if the clock that is shown is the "real" clock or is syncronized with the "real" clock. Sometimes (many times?) the clock on the screen is not official, so the light is used.
