Abstract	This paper will describe a method for providing a useful intelligence down a low-bandwidth output stream from a high-bandwidth input stream. Many intelligence systems take advantage of streaming video and utilize high-bandwidth data links to supply information. The issue is that high-bandwidth systems typically require larger equipment, better line-of-sight, and more complex gear to keep a reliable link. The intended platform for the system described in this paper is an unmanned aerial vehicle, so the limitations of high-bandwidth equipment become more significant in a tactical scenario. By providing snapshots from the high-definition (HD) video stream, the system is able to send data to users that may not have the capability, due to a myriad of reasons, to acquire a full HD video stream. The system was developed using a Gumstix Verdex 600Mhz computer and the frame acquisition algorithm is written in C. Testing was done using HD video files streamed by VideoLan Client (VLC). The system is capable of outputting JPEG images at a maximum interval of 30 seconds. The capture system provides a method of reaching out to more users and providing functional data.
