General System Information

3.1 Overview

The M2ECHPT is a second generation AVC HD/SD COFDM transmitter that combines all the features
and capabilities of Cobham Surveillance's (CS's) Messsenger 2 AVC HD/SD Transmitter with the
additional features listed in the Key System Features section below. Key features include optional Dual
Audio/Video/Data processing with end to end system-level latencies of down to
CS Receiver/Decoders.
The Ultra-low system latency greatly enhances real-time operating when the link is used in time critical
situations like piloting Unmanned Aerial Vehicles (UAVs) or Unmanned Ground Vehicles (UGVs) or in
threat response. Optional Dual video processing enables 3D content collection which provides depth
perception and greater control for UGV applications requiring fine spatial operations like explosive
device de-arming. The M2ECHPT's 3D capability also enhances Entertainment, Sports, and ENG

applications.

The M2ECHPT can optionally provide time-correlated KLV-1 and KLV-2 META data processing
used in Airborne Surveillance Applications and Geospatial determination. The META data can be
extracted from the SDI/HD-SDI video's ancillary data space or input on a separate RS-422 interface.
3.2 Applications
The M2ECHPT Transmitters can be used in the following environments:
 Helicopter Links
 UAV/UGV Applications
 Audio/Video Surveillance
