The TC8276 Series video processors digitally capture the
full video from four sources, reduces these images to
quarter-screen size, and combines them to provide a
quad display. The TC8276 Series will accept both
monochrome or color inputs. The output will be a
monochrome quad display. Any color inputs will display
color in the full screen mode.
The TC8276 accepts inputs from any EIA, RS-170 525
line, 2:1 interlaced source. The TC8276X accepts inputs
from any PAL, CCIR 625 line, 2:1 interlaced source.
These units will accept inputs having video signals in the
range of 0.5 Vp-p to 2.0 Vp-p. These units provide two
monitor outputs. The QUAD VIDEO OUT displays a
continuous quad display or a digitally-zoomed frozen
screen. The VIDEO OUT displays the quad presentation
or any of the four video outputs full screen. The VIDEO
OUT also displays a numeric on-screen camera identifier.
Automatic gain and level circuits provide balanced
brightness and contrast in all quadrants. The TC8276
Series achieve a real time update rate (30 frames-per-
second) when used with line-locked cameras that have a
phase error of less than 5 degrees.
Front panel controls allow manual operation for full
screen video or four quadrant display on the monitor.
These displays can be sequenced at a fixed two second
dwell. If selected, the quad display can be included in the
sequence.
Alarm contacts enable remote call up of any of the four
camera inputs on the VIDEO OUT monitor, and freeze
the quadrants on the QUAD VIDEO OUT monitor.
Flashing on screen "ALARM" indicates cameras in alarm.
An alarm output is provided for control of a VCR or other
alarm activated devices. Front panel push buttons
"freeze" the current picture in any quadrant for further
inspection. Flashing on-screen indicators identify frozen
quads. The frozen quadrant can be "zoomed" to a full
screen display.
