Video processors are specialized hardware and software systems designed to handle the real-time manipulation, enhancement, and analysis of video feeds. They play a critical role in tactical and strategic defense operations by processing multiple video streams, integrating camera system inputs, and applying advanced algorithms for video compression, stabilization, object tracking, and scene interpretation.
These processors can be standalone modules or integrated into broader platforms such as unmanned aerial systems (UAS), manned surveillance aircraft, marine vehicles, and ground-based ISR towers. Their capabilities are often tailored for military-grade robustness, featuring high frame rates, encoded video transmission formats like H.264 and H.265, and support for standards such as MISB and KLV metadata.
