Message of VC application running on Centaurus: decodeFrameNumber[Port0]...

Hi,

I just want to know what the following messages mean that appear during the VC application run time.

decodeFrameNumber[Port0]: 44400

frameNumber[Port0]: 45000

(1) - 30 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

(0) - 30 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

And, what if the number '30' is changed to some lower value? Say,

(1) - 29 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

(0) - 30 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Thanks!
