Operating Concepts
A source shift button toggles all source 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. (The concept is similar to the shift key or
the ‘caps lock’ key on a keyboard.)
A destination shift button is a toggle. 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.
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.
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.)
Hold
Hold mode (and hold buttons) apply in ‘Single Destination with Breakaway’ mode and ‘Limited
X-Y’ mode.
Breakaway
In single-destination mode with breakaway, a hold button retains breakaway levels after a take.
Simply press the hold button at any time before the take.
A hold button is a toggle. Press it once to put the panel in hold mode; press it again to remove hold
mode.
