Adjusting playout timing to match E to E timing
In E to E Timed Output mode, all playout timing is delayed from the system reference
by +16 lines to match the E to E delay through the system. This ensures clean switching
between video inputs and decoders outputs. You can use the Output Timing Offset
adjustment, provided for each video output, to meet downstream timing requirements.
To adjust playout timing to match E to E timing:
1. Choose
Video Timing
in the Configuration Manager window. The Video Output
Timing dialog box appears.
2. Click
Next
to navigate to Video Timing page 4 of 5, Reference Timing Offset.
3. Select
E to E
output timing mode, then click
Finish
. Playout timing is now set to
match E to E timing.
NOTE: If you changed the playout timing mode, restart all Profile applications
currently using the system.
4. Some playout timing adjustment may be required to satisfy downstream timing
requirements in your system. If so, adjust playout timing as follows:
a. Select
Video Timing
in the Configuration Manager window. The Video Timing
dialog box appears.
b. Click
Next
to navigate to Video Timing page 3 of 5.
