This past Sunday I was on vacation and the video team had some problems. For reasons they, nor I, can understand the program bus was freezing intermittently. I cannot even think of how to duplicate this if I wanted to. According to the director, they were not doing anything differently at all when the freezes occurred.
We are using 3 JVC KY17 cameras, and a Laird Phatcat system to save on cabling costs. We are component into the SX8 from JVC RMP200 CCUs. It is very simple and straight forward.

I have never had any trouble whatsoever with the Cat5 system and do not want to blame it on that. I suspect a carbon based error, but I am not sure what the director might have done, and have no desire whatsoever to blame anyone.

I watched the DVD and the freezes are desaturated (although the yellows and reds remain saturated) and the audio continues underneath in sync. I could not determine a consistent time of the freezes although they each lasted for a few seconds. Also, there is no discernible pattern to when they occur (IE every 5 minutes). 2 of the 3 cameras froze, the other was not used very often and I did not see it freeze. I had previously removed all of the transitions from the bin except the crossfade to avoid crazy choices on the tape.

My RS-8 was being serviced (again) so they were directing using our logitech wireless keyboard and mouse.

Any thoughts?

...they were directing using our logitech wireless keyboard and mouse. Any thoughts? Preliminary thought from myself Mike, is that a wireless keyboard and mouse combo is potentially a disastrous way to live-switch, as it can be terribly unreliable with unexplained, unpredictable, problematic results.

Goodness knows I wish our recently purchased high-performance PC had not shipped with a high-end wireless combo out-of-the-box, from Microsoft!

One other thing: The use of high-efficiency compact fluorescent lighting have also been known to potentially wreak havoc with the operation of some electrical appliances including computer based systems.

Thanks for that info. Both of those items were in play. Wireless keyboard and mouse and the lovely, mood setting fluorescent lights in my closet...ahem..control room.

I will continue to do some testing but definitely factor that in.

There have been times when nearby cel-phones (and maybe cordless phones?) also caused havoc ...
