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.
