Glossary Of Terms - Philips Allegiant LTC 8500 Series Instructions For Use Manual

AUXILIARY - An auxiliary is an additional function of
the remote receiver/driver which permits on/off
control of outputs available to the user. In the
Allegiant system, there are four relay outputs
available which can be configured for contact
closures, 24 VAC output, or LINE voltage output.
They can also be set to activate either momentarily
or in a latching mode.
BOOTSCREEN - A unique feature of the Allegiant
system wherein a section of nonvolatile memory can
be used to store specialized factory programming. A
program of this type could then provide custom
features which ordinarily would not be obtainable.
DITHER - A receiver/driver feature which provides
added protection to very low light level cameras by
periodically panning a few degrees left and right
automatically.
LOCKOUTS - The ability of a switcher/controller
system to restrict access of operations to certain
system functions or features. The Allegiant system
has two modes of lockouts. The first mode is based
on operator priority level. This allows a higher priority
level operator to lockout lower level operators from
either viewing or controlling specific cameras. The
second mode involves Master Control Software
setups which can:
1. Restrict operators/keyboards from viewing/
accessing any camera.
2. Restrict operators/keyboards
controlling/
accessing any pan/tilt.
3. Restrict operators
keyboards,
4. Restrict operators/keyboards from accessing
certain monitors.
LOG-ON, LOG-OFF - A selectable feature of the
Allegiant system which requires operators to enter a
User number and an optional password into the
keyboard prior to having
operations.
MATRIX SWITCHING - The ability of a switching
system to display any camera on any monitor or the
same camera on all monitors.
PHASED CAMERAS - Properly integrated cameras
which give a roll-free video display when switching
from one camera to the next in a sequential switcher
system. Phased cameras are the result of line-locked
cameras being powered from the same AC power,
externally synchronized,
adjusted on cameras equipped with this option.

PRE-POSITION - The ability to store the position of
a pan/tilt and zoom lens so that the same desired
scene can be later recalled automatically. With the
Allegiant system, there can be multiple preset scenes
stored for each pan/tilt camera. For each scene, the
pan, tilt, zoom, and focus settings are stored.
SalvoSwitching - The ability of the Allegiant system
to switch multiple video monitors as a synchronized
group. Since multiple monitors switch together, the
operator can view multiple scenes of a specific area
or zone before switching to the next area.
SEQUENCE - A series of camera scenes that can be
preprogrammed to automatically
Allegiant system can store up to 60 separate
sequences, with each one capable of having a
random camera order, individual camera dwell times,
and SalvoSwitching steps.
TIME EVENT - An Allegiant system feature
(available with the optional TC8850 Graphical User
Interface software or the optional TC8x59 Master
Control Software) that enables various system
functions to be periodically activated automatically.
Event functions such
broadcasts, sequence and switching operations,
receiver/driver actions, message printing, alarm
settings, and execution
programming can be stored in the system memory to
be executed at a pre-determined time. The task can
be specified to begin on a specific year, month, day,
and time, and can be programmed to repeat at
intervals ranging from every five minutes up to a
year.
VERTICAL INTERVAL SWITCHING - Vertical
Interval switching is a method of switching video
from camera to camera during the vertical blanking
interval period of the video signal. This minimizes
visual switching disturbances such as rolling, jitter,
video flashes, etc. and eliminates frame information
loss when used with video tape machines.
VersAlarm - A flexible system of configuring alarms
using the optional TC8850 Graphical User Interface
software or the optional TC8x59 Master Control
Software. Multiple groups of monitors can be
programmed to respond to alarm conditions in
various ways. In addition, each alarm may call up
from 1 to 4 cameras with user-selectable remote
operations. Alarm video may also be programmed to
display user-defined alarm titles on the monitor
overlay display rather than the usual camera titles.
