Configuring for Switching
Note:
To avoid multicast stream over-subscription, configure your UHD stream sources and destinations
on a different level as the HD/3G sources and destinations. This will prevent SDNO from routing UHD IP
steams to a HD receiver channel.
SNP does not support clean switch between two different audio types, for example switching between
sources with stereo and monitor audio. Quiet switching, which mutes down, then switches, then
unmutes, can switch between various types of audio.
The Conversion personality supports both HD and UHD sources and destinations at the same time. The
last one used will be the one that is updated on the soft panel control.
Note:
If you switch to an empty multicast stream, the output video will freeze or go to black depending
on the setting for the Loss of Video (LOV) mode parameter. If it is set to freeze, the previous stream's
content will not be preserved.
SDNO Indexing
Programs in the SNP Manager GUI are indexed 1 to 4 per section. A popup lists the SDNO video stream
indexes for the different types of video streams (3G, UHD, and Proxy) in the header for each of the
following sections:
•
IP video Rx
•
IP video Tx (as below)
