Source Shift
Source shift applies in all modes.
Each source button can represent two sources. A ‘Source Shift’ button selects which of the two
sources the source button will select. (The concept is similar to the shift key or the ‘caps lock’ key
on a keyboard.)
A source shift button is a toggle that enables either the first or second source of source buttons.
The source shift button is low-tally when it has enabled the first source. It is high-tally when it
has enabled the second source.
A source shift button toggles all source buttons. However, source shift does not apply to
‘Source/Destination’ buttons.
Destination Shift
Destination shift applies only in ‘Limited X-Y’ mode.
Each destination button can represent two destinations. A ‘Destination Shift’ button selects
which of the two destinations the destination button will select.
A destination shift button is a toggle that enables either the first or second destination of desti-
nation buttons. The destination shift button is low-tally when it has enabled the first
destination. It is high-tally when it has enabled the second destination.
A destination shift button toggles all destination buttons. However, destination shift does not
apply to ‘Source/Destination’ buttons.
Levels
In NV9000-SE Utilities and in the NV9000 router control system, routes occur on levels. A level is
typically SD, HD, analog video, AES, analog audio, or machine control. Various devices are
defined as sending and receiving signals on certain levels. The set of levels handled by a device
belong to what is called a level set.
A source can be routed to a destination if it has the same set of levels, i.e., it belongs to the same
named level set. A source can be routed to a destination in a different level set if the NV9000
configuration has the appropriate inter-level set mapping.
The effect of this is that when you, the operator, choose a destination, the NV9000 software
recognizes which source devices are allowed to be routed to the destination and limits your
selection to those sources.
Breakaway
Routes can be all-level in which case they are taken on all levels defined for the destination. The
acceptable sources for a route have the same levels as, or some configured mapping to, the
levels of the destination.
A breakaway is where you take different sources to the same destination — on different levels.
It is not possible to take different sources to the destination on the same level. For instance, you
cannot take SD from two different sources. The outcome would be noise even if you could do it.
(That is because routers are not mixers.)
