DL Micro™ Digital Data Link and Video Processor

warfighter holding unmanned aerial vehicle

SRI’s DL Micro™ digital data link and video processor delivers actionable video from unmanned air and ground vehicles. This OEM module uniquely combines H.264 encoding and an IP-based digital data link with the fundamental benefits of image stabilization. Weighing only 46 grams, the module meets the low size, weight, and power (SWaP) requirements of unmanned defense systems.

The DL Micro digital link uses advanced image processing to maximize image quality for better compression. Without DL Micro image stabilization, video from moving vehicles is shaky, making it hard for operators to interpret the content. Critical information can become ambiguous or compromised. Additionally, image shake wreaks havoc on digital video compression, stealing bandwidth away from detail.

With the DL Micro digital data link, video becomes easier to transmit. It maximizes the real-time information delivered from unmanned platforms, enhancing situational awareness. Decision-making becomes faster and more accurate.
