Figure 1 - AD 1476 SuperQuad HR
SYSTEM DESCRIPTION
The AD1476 SuperQuad HR combines a high-resolution quad
display, a multi-function video switcher, and a VCR quad
playback expander with a microprocessor control unit in a
single rack/tabletop enclosure. The VCR playback functions
provide jitter-free expanded pictures from full frame recorders
and digitally enhanced enlargements from single-field, time-
lapse recorders.
The built-in sequential switcher adds the channel-input number
and a user-entered 8-character camera identification data to
each video input. On-screen menus are provided for setup of all
user-programmable functions. Manual or automatic alarm
callup to the Call output are provided. The SuperQuad also
adds date/time data to the on-screen display and provides
RS232 remote control.
