Operation
Source Shift
Source Shift
Source shift also applies in either mode.
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: it 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 affects all source 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. In most cases, you would take only certain levels of a new source to a destination
that already has a source on its various 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 'Limited X-Y' mode.
Breakaway
In limited X-Y mode (with breakaway), a hold button retains breakaway level selections
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.
