The TC8278 Series video processors
digitally capture the full video from up
to eight sources, display them
selectively full screen, or reduces these
images to quarter-screen size, and
combines them to provide a two page
quad display. The TC8278 Series will
accept monochrome and/or color
inputs and provide monochrome
and/or color display capabilities in the
full screen and quad modes.
The TC8278 requires no external
synchronization and accepts inputs
from any EIA, RS-170 525 line, 2:1
interlaced source. The TC8278X
accepts inputs from any PAL, CCIR
625 line, 2:1 interlaced source.
The TC8278 Series provide two
monitor outputs. The MON A output
displays two digital quad formats of the
eight 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 eight
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 TC8278
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. Monitor 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 eight 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.
