52 Appendix B: Technical information
SDI video input connectors
The two SDI video input connectors on the Matrox Orion HD board are SMB
connectors, used to receive HD/SD 3G-SDI video signals. Each connector can
receive a different video stream. The SDI video input connectors need to be
connected to SMB to BNC cable adapters. The BNC connectors on these adapters
are high-quality
BNC connectors. The SMB to BNC cable adapters connected
to the Matrox Orion HD board and the BNC input connectors on the SMB to
BNC cable adapters are shown in the following image.
Their pin assignment is as follows:
You can use a standard BNC-to-BNC video cable (available from your local
electronics store) to interface an HD/SD 3G-SDI video source with one of these
connectors. If the cable has to be longer than normal, you will need a very good
cable to prevent loss. As the data rate increases, you should use a shorter cable for
a clear signal.
