A Primer…. Motion Imagery & Applications
Background & History • “Motion Imagery” instead of video because the term “video” excludes some non-traditional uses of multi-frame imagery • Specialized cameras for docking applications, payloads, etc.
Green Book Overview • Three main sections • Section 2 documents deployed digital video systems • Section 3 is a primer on digital video parameters • Section 4 outlines potential subjects for inclusion in a Magenta Book
Applications of motion imagery • Personal Video Conferencing • Medical • Situational Awareness • Engineering/Science • Public Affairs • HiRes/specialized motion imaging • Scenarios • Spacecraft to spacecraft • Spacecraft to ground station • Ground station to ground station • Ground station to spacecraft
