*Protection against loss or degradation of picture. Low protection does not
necessarily mean picture loss or degradation will result, as this would depend on
the network architecture and numerous other factors.
**The term
latency
is referring to latency on the network. The network in
this context refers to the IP Mini Converters end-to-end — from video into IP
Transmitter to video out of IP Receiver, including IP switches along the way.
Unlike the five pre-built System Modes just described, each of which are "safe,"
the Advanced Mode, described below, does not guard against a user applying
contradictory settings that could provide unpredictable results.
