Introduction
The video, audio, and other signal types composing a device’s output are generally considered
levels in the broadcast industry. We say that devices send and receive signals on several levels.
In NV9000-SE Utilities, we call these virtual levels to contrast them with the physical levels that
partition routers.
Another way to think of levels is to imagine the two-dimensional X-Y router matrices switching
different signals being stacked into layers. The layers can be considered levels.
In NV9000-SE Utilities, virtual levels are abstractions that apply universally to (1) devices and (2)
routers in your system. Physical levels are concrete, not abstract, and apply only to one router
matrix or one section of a router matrix. Physical levels, as stated, are also called partitions.
The names of virtual levels are important and widely used. Control panel operators can see and
select virtual levels
— by name. The names of physical levels are known only to the few persons
who configure the NV9000 system.
In NV9000-SE Utilities, a virtual level type is a named entity that represents one or more signal
types. As an example, the virtual level type “HD” might correspond to the following signal types:
1080i / 59.94 720p / 29.97 1080p / 23.98
1080i / 50 720p / 50

These are the signal types that would be allowed to be switched in the physical level that corre-
sponds to any virtual level named “HD.” (More than one virtual level can be named “HD.”)
1. These are default signal types. They are identified in the ‘Signal Type’ table, but are not further defined
in NV9000-SE Utilities. You can modify the ‘Signal Type’ table to suit your system’s requirements.
