Concerto — Installation and Service Manual 177
Glossary
FC
Frame Controller.
FET
Field Effect Transistor.
First Come First Served (FCFS)
Tieline status where it is not necessary to cre-
ate a reservation to use the specified Tieline.
Flag
A parameter that can be set in a control panel
template to control how the panel operates.
Flip-Flopping
Alternately connecting each of two different
Sources to a single Destination (at a designat-
ed switching rate (See:
Chop ).
GBR (Green, Blue & Red)
The three primary colors used in video pro-
cessing, often referring to the three un-en-
coded outputs of a color camera. The
sequence of GBR indicates the mechanical
sequence of the connectors in the SMPTE
standard. Also see: RGB.
GPI
General Purpose Interface.
GSC
Global Serial Channel.
Hardware
1. Electrical devices connected through phys-
ical wiring. 2. Electronic programming tech-
nique using physical connections and
therefore essentially unalterable.
HDTV
Television with a resolution approximately
four times that of Conventional Definition
Television and a 16:9 (H x V) picture aspect
ratio.
Heartbeat
A health status message provided by net-
worked frames that are polled by MCPUs.
Horizon
A Grass Valley line of routing switchers.
HX
Grass Valley Horizon Series Crosspoint
Routing System.
IBOP
Interconnect /Break Out Panel. An option
panel used to add BNC connectors to an au-
dio matrix using 50-pin D connectors.
ID or IDENT
A software routine that identifies a device
(e.g. a control panel). Includes such informa-
tion as:
• controlled Destination
• active tally level
• panel name
• software version
• system name
I/O
Abbreviation for input/output. Typically re-
fers to sending information or data signals to
and from devices.
Input
A single physical, numerically designated
connection point of an in-coming signal to a
matrix. One or more inputs can be assigned
to a Source name during System Configura-
tion.
Input Offset
Unlike traditional multi-level systems,
Sources do not have to use the same input
connector number on each matrix Level (i.e.
RGB inputs for one Source can use input #1
in one matrix for R, input #4 in another ma-
trix for G, etc.) The offset of the input num-
bers used is logged in the System
Configuration.
