Configuring Your GV Matrix
Timecode
2 Click the URS Generation Mode pulldown.
3 Click to select the URS Generation mode:
Mode Means
Normal The URS frame rate matches the selected reference input, i.e. only 29.97 or
25 Hz.
Free Run All URS synchronization signals are generated, even the frame-rate-
mismatched ones. So, in the same frame, some cards can work in 25Hz
frame rate and other cards in 29.97Hz. The phase relation between these
two frame rates will be arbitrary, thus the name "free run"
Note:
In this release, only NORMAL is supported, no matter what is selected in the pulldown.
