• Current Time (HH; MM; SS) and Date (DD; MM; YY).
• Camera Identifier (0…9 numeral and an ABC character).
• Power supply voltage (+ 18.60 V) with 1% accuracy.
• 4 mnemonic symbols corresponding to 4 discrete inputs.

TITR system includes two controllers: operating controller and backup controller.

Operating controller is designed to control video-signal structure, adapt to horizontal frequency of the used camera, collect information and display it on the screen. It also controls time.
