Lists
The NV9601 presents several items in lists: levels, MD devices, salvos, and category devices.
You can scroll through lists to view, and select, entries in the list.
Category device lists are different from other lists. The list itself does not appear on the
display. However, the display does show the device in the list you have presently chosen.
To scroll through category devices, a ‘Scroll’ button is required on your panel. Press a
category button, then press the ‘Scroll’ button to enable scrolling through devices, and
then use the ‘Page Up’ and ‘Page Down’ buttons to advance to the previous or to the next
device in the list.
The MD device list, the salvo list, and the level list do appear on the display. For MD devices,
salvos, and levels, it is sufficient just to press the ‘Page Up’ and ‘Page Down’ buttons to
scroll. The display scrolls in “pages” of 8 items at a time.
Operating Concepts
Status for most or all operations is presented on the alphanumeric display (and occasionally
on certain 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.)
Level Mapping
If a level was level-mapped, the display shows a plus sign next to the level name.
See Level Map on page 46 for usage information.
