Synchronizing The Sdi Output To An External Source - Nvidia Quadro K4000 User Manual

Synchronizing the SDI Output to an External Source

You can synchronize the SDI output with other equipment in a broadcast or post
production environment.
Supported Synchronization Methods
The SDI Signal Settings tab provides two methods for synchronizing the SDI output to
a common sync source—pixel-accurate or frame-accurate synchronization.

Pixel-accurate synchronization synchronizes the pixel scanning of the SDI output
to the house sync signal. When using pixel-accurate synchronization, the SDI refresh
rate is determined by the sync signal.

Frame-accurate synchronization synchronizes the frame rate of the SDI output to
the house sync signal. The sync signal determines the available SDI signal formats.
Supported Synchronization Signals
The NVIDIA driver 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.)
Connecting to an External Synchronization Source
To use an external sync source:
1
Connect the sync signal to the INPUT BNC connector.
You can connect multiple systems to the same house sync by daisy-chaining the house
sync cable to each card using BNC T-connectors.
2
Follow the instructions in
external sync signal.
The driver will not detect a valid sync signal until the correct signal type is configured
in the NVIDIA Control Panel.
