Minimizing Glass-to-Glass Latency and Enhancing Situational Awareness

Video management systems provide those who are operating manned and unmanned ground vehicles with critical visibility and situational awareness. To ensure the safety and security of people and equipment inside and outside the vehicle, this vital visual information needs to be available as close to real-time as possible.

It doesn’t take much imagination to consider the effects a video system with high latency can have on situational awareness. The critical delays caused by video latency can mean warfighters inside the vehicle are unaware of an approaching enemy, man-made or natural obstacles, or warfighters or civilians outside the vehicle, until it’s too late.

The viewing experience of these delayed images can also cause motion sickness for those inside the vehicle. When what you see doesn’t match what you feel, the discrepancy can cause inner ear disturbances that lead to nausea, dizziness, and vomiting. These uncomfortable physical manifestations can easily become a distraction, further impacting a warfighter's situational awareness.

Ground Vehicle System

Ground Vehicle Video System

While the risks to human safety are less when unmanned ground vehicles are used, the remote location of the vehicle driver means the video stream must travel further before it can be acted upon. This distance naturally increases latency, compounding the dangers associated with delayed video streams.

No matter what the vehicle type or mission, video latency, and its effects on situational awareness, make it extremely difficult for operators to have complete confidence that what they are seeing aligns with reality. The combination of uncertainty and delayed images can cause hesitancy which increases threat response time. This delay in response time can result in collisions with obstructions or humans or entering dangerous situations or landscapes.

The key to increasing situational awareness for today's ground combat vehicles is in designing a video management system that reduces latency from end to end. From the cameras to the ruggedized displays – each component in the video management system needs to be designed with low latency in mind.
