Using SDNO with SNP
Using SDNO with SNP
SNP requires SDNO version 2.8.1 or newer.
Configure the SNP independently via the SNP Manager UI. Specific SNP settings that the SDNO
Controller requires are covered here.
Note: SDNO only supports multicast routing.
For the purposes of the SDNO, an SNP transmitter channel is a source, because it is receiving SDI and its
output is IP. A SNP receiver channel is a destination, because it is receiving IP and its output is SDI.
SDNO Controller 2.6 and up support reading and setting source addresses for SNP in the SDNO System.
This functionality is useful when using Source Specific Multicast as the method of routing multicast
signals; for example, if you have SNP in your SDNO System, you can now route their signals via SDNO
Controller in an SSM environment.
As of SDNO Controller 2.5, the source address is read from the transmitting device and
written/populated onto the receiving device channel that corresponds with the multicast group being
requested. When a Take operation is performed, the Primary Mcast Src 2 address is set to the
transmitter's secondary stream source address and the Secondary Mcast Src 2 address is set to 0.0.0.0 .
Workflow for SNP and SDNO
SNP needs to be defined as an endpoint in SDNO, a point where content comes in and goes out of the
routing system.
If you are using the SDNO Client, you must launch it using Internet Explorer.
1. In the SDNO main window, click Configure System, and then choose Device Foundry > Endpoint
Device > Add Device on the subsequent screens.
