The TC8277 Series video processors
digitally capture the full video from
four sources, reduce these images to
quarter-screen size, and combine them
to provide a quad display. The TC8277
Series will accept monochrome and/or
color inputs and provide monochrome
and/or color display capabilities in the
full screen and quad modes.
The TC8277 requires no external
synchronization and accepts inputs
from any EIA, RS-170 525 line, 2:1
interlaced source. The TC8277X
accepts inputs from any PAL, CCIR
625 line, 2:1 interlaced source.
The TC8277 Series provide two
monitor outputs. The MON A output
displays a digital quad display of all four
inputs or a full screen image of any of
the input cameras. Full screen displays,
including the VCR input, have
positional 2X electronic zoom
capability. Freeze and zoom
capabilities are available with MON A.
The second output, MON B, is used
for selecting analog full screen displays
of the four video inputs. A user
programmable sequence is available on
the MON B output. Both the MON A
and MON B outputs display a user
display selectable camera ID number,
programmable titles, time/date, and on-
screen status information.
Automatic gain and level circuits
provide balanced brightness and
contrast in all quadrants. The TC8277
Series achieve a real-time update rate
(30 frames-per-second) when used
with line-locked cameras.
Front panel controls allow password
protected menu access, and full manual
operation of both MON A and
MON B functions. MON B sequence
features offer a 16 entry list which can
include the quad display, and adjustable
dwell of 1 to 99 seconds.
On-screen menu access provides user
programmable operational and display
modes.
Alarm contacts provide remote call up
of any of the four camera inputs on
the MON B monitor, and selectable
full screen on MON A monitor. Other
alarm features include a flashing on
screen "ALM" indicator, an alarm
output relay for control of a VCR or
other alarm activated devices, front
panel alarm clear, and user
programmable alarm capture.
