Glossary
AES/EBU
(Audio Engineering Society/European Broadcasting Union). AES and EBU are standards
organizations.
Breakaway
A condition where a destination has multiple sources on different levels.
Category
A category represents a set of devices. (The concept of categories exists to make it easier to
select devices at a control panel.) A category can contain sources, destinations, or devices that
are both sources and destinations. Each device in the category has a unique selection index
within that category. Each category has a mnemonic ID associated with it.
Data Routing
Data routing (a.ka., machine control routing) is a bidirectional form of routing. Routes are char-
acterized by a controlling device and controlled device(s). The NV9649 provides certain data
routing options including a ‘Broadcast’ button.
Device
A “device” is a grouping of input and output ports that define a logical entity. (The logical entity
often represents a real device, but it does not have to be a real entity.) For example, a system
might have 3 levels: video, AES, and time code. A hypothetical device in this system is Camera 1,
which consists of video on input port 1 of the video router, AES on input port 5 of the AES router,
and time code on input port 8 of the time code router.
GPIO
General Purpose Input and Output. A generic term for the NV9649’s tally interface. The tally
interface is called the “GPI Interface” at the rear of the NV9649.
Level set
A level set is a group of virtual levels that are commonly used together when switching devices.
A level set also defines the mapping of each virtual level within the level set to a single physical
level. All levels in a level set have a unique display index within that level set.
Multi-Desti-
nation
(Mode)
A mode on an NV9000 control panel that presents many destinations at once, in contrast to X-Y
mode. An operator may route sources to multiple destinations in a single take. Multi-destination
mode does not permit the selection of breakaway levels.
Operator
The term operator (a.k.a. user) usually refers to users other than the system administrator or
configurer. An operator is responsible for making the routes.
Physical Level
Multiple routers provide different “physical levels” on which to switch the signals of devices. Any
particular device might send or receive HD, SD, AES, time-code, or machine-code signals.
PIN
The system administrator may create a single “super user” personal identification number (PIN)
that functions as a passcode. A PIN is 4–6 digits in length. The PIN allows certain operators to
perform functions such as (1) forced release on a control panel that is configured for normal
release or (2) changing the ID of a control panel.
Port
A port is the physical connection on a router. A port can only be an input port or an output port.
Salvo
A salvo is a stored group of commands that can be recalled and executed at a NV9000 control
panel.
Source/
Destination
The term “source device” is used interchangeably with “source” and the term “destination
device” is used interchangeably with “destination.” A source is a device that is connected to one
or more input ports. A destination is a device that is connected to one or more output ports. An
example of such a device would be a monitor.
