CHAPTER 2 NVIDIA Graphics-to-SDI Connecting the SDI Video Output Refer to Figure 2.1. • 4:4:4/4:2:2:4/4:4:4:4 dual-link signals are sent to the V1 Out and V2 Out connectors (corresponding to the fill + key signals respectively). • 4:2:2 single-link signals are sent to the V1 Out connector only. In application control mode, using the APIs, an additional 4:2:2 signal can be sent to the V2 Out connector. Connecting to an External Sync Source • You can genlock the output to an external digital or analog sync source. 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 appropriate BNC connector as indicated in Figure 2.1. You can connect to both types of sync sources at the same time. The software gives precedence to the SDI signal, but you can use the control panel to choose which signal to use (see "Synchronizing the SDI Output to an External Source" on page 22.)

Connecting the SDI Video Output
Refer to
Figure 2.1
.
•
4:4:4/4:2:2:4/4:4:4:4 dual-link signals are sent to the
V1 Out
and
V2 Out
connectors
(corresponding to the fill + key signals respectively).
•
4:2:2 single-link signals are sent to the
V1 Out
connector only.
In application control mode, using the APIs, an additional 4:2:2 signal can be sent to the
V2 Out
connector.
Connecting to an External Sync Source
•
You can genlock the output to an external digital or analog sync source.
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 appropriate BNC
connector as indicated in
Figure 2.1
.
You can connect to both types of sync sources at the same time. The software gives
precedence to the SDI signal, but you can use the control panel to choose which signal
to use (see
“Synchronizing the SDI Output to an External Source” on page 22
.)
