Connecting the SDI Video Output
Refer to Figure 2.4.

4:4:4/4:2:2:4/4:4:4:4 dual-link signals are sent to the FILL and KEY connectors.

4:2:2 single-link signals are sent to the FILL connector only.
In application control mode, using the APIs, an additional 4:2:2 signal can be sent to
the KEY connector.
Connecting to an External Sync Source

You can genlock the output to an external digital or analog sync source. Several
systems can also be frame-locked.
NVIDIA Genlock supports the following two external synchronization signal types:
•
SDI
•
Composite, which can be one of the following:
Composite Bi-level (NTSC or PAL sources use bi-level composite signals.)
Composite Tri-level (HDTV sources commonly use tri-level composite signals.)

To use an external sync source, connect the sync signal to the INPUT BNC connector
as indicated in Figure
using the NVIDIA Control Panel.
