Interesting Picture

[Drizzle]

I could be completely wrong here, but I think the shot clocks provide the most accurate timing because there is less distance (less wire usually) from the scoreboard control to the display. Plus, they are LED displays so I would think they have faster response times than traditional displays.

Also, the difference between the shot clocks and timers on the scoreboard video displays (the ones that are becoming more common in the professional arenas) are even worse, I would guess because of the rendering needed to display the digits. I'll see if I can't snap some photos showing the difference when I go to my next game.

As for the TV insets, aren't they usually the clock from the shot clocks? I've only seen production on the local level (i.e. community broadcast), but I would think they have one camera pointed at the entire display to get the insets for both the shot clock and game timer.
