Chapter 04 : Linux—Using the Graphics to Video Out Control Panel
Using Frame Lock
Frame lock synchronizes the frame rate of the SDI output to an external synchronization
source.
When using frame lock, only modes that are valid for the frame rate of the sync source
can be used for the SDI output. The valid modes will appear in the
Output Video
Format
list.
Supported Synchronization Signals
NVIDIA Genlock supports the following external synchronization signal types:
SDI
Composite Bi
‐
level (NTSC or PAL sources use bi
‐
level composite signals.)
Composite Tri
‐
level (HDTV sources commonly use tri
‐
level composite signals.)
Synchronization Instructions
Basic Setup
The following are the basic steps to synchronize the SDI output.
1
Connect the external sync source to the appropriate BNC connector on the graphics
card.
See
“Understanding the Connections” on page 9
for instructions on connecting the
external sync signal to the graphics card.
2
Configure the sync source.
a
Open the
Graphics to Video Out: Synchronization Options
page.
Figure 0.4
Synchronization Options Page
b
Click the
Sync Mode
list arrow and then click either
Genlock
or
Framelock
synchronizing modes.
