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 destination
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 con-
figuration has the appropriate inter-level set mapping.
The effect of this is that when you, the operator, choose a destination, the NV9000 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.
