Hey, congratulations on not having a life!

Looks like I've still got some work to do to catch up.

You can say that again, again.

Aw, never mind.

The difference in the clocks will NOT be due to wire length. For a 1/10th second difference, the wire to one display would have to be about 10,000 miles longer than the other one.

What is differnet is the control circuitry and the display technology.

The control circuitry that decodes the control signals from the console could be faster in one clock unit than the other.

The lights that illuminate the numbers could be of a different type...LED, Fluorescent, Incandescent, etc. Those have reaction times that are definitely different. LED's turn on/off nearly instantaneously while incandescents are much slower to change state. I think fluorescent's are also slow.


They are also not necessarily a full 1/10th apart. The could be just 1/1000th of a second apart and the camera captured the image just after one changed and just before the other changedd....giving the impression that they were 1/10th apart...could be 32.999 and 33.000. The only way to really tell would be to have high-speed video....the number of frames they're different times the duration of the frame would give you close to the real difference....if there are enough frames of difference to get a good measurement.

That's my guess.

That said, it would be really interesting to hear the discussion if a last second shot was counted/not counted based on one clock view, then a picture like this came out (with either shot clock at 0.1 and scoreboard at 0.0 or vice versa).

FWIW, when I do the clock, I watch the clock over the backboard. That's the only way I can see when the ball goes through and compare it to whether or not we're under (not at) 1:00.

There was a prominent game in this area last year where this was an issue.

SLU vs Missouri State at the Scottrade Center

Here's another photo of the difference. The wraparound LED video clocks are significantly slower. Watch the shot clocks.

Wow!!! This is better than the Discovery Channel!!!

Maybe you and I should go into the arena clock synch business together.

Lotta money out there to be made on this Camron... we can even upgrade them to Monster Cables

In the broadcast world, Monster Cables is like a swear word!

Yeah I know that but we won't be dealing with the techies... we'll sell this to the front office types. They'll love it!

If you don't know what we're talkng about check this out

So, instead of a monster cable product, would you like to buy a set of my super oxygen-free, aligned crystal, helical wound, spacially precise, carbon fiber jacketed, 110% copper, sound pipes?

I was going to until the mention of 110%. One can't have more than 100%.
