VISUAL INCIDENT DETECTION EVALUATION OPERATION V.I.D.E.O. FINAL REPORT
The V.I.D.E.O. project undertook the development and deployment of an image transmission system that could transport pictures from a remote site to a control point. This transmission was to occur over common carrier, low cost lines. The project upgraded the state-of-the-art slow scan image transmission from one picture every 71 seconds, first with jet propulsion hardware to one picture every 30 seconds. Dalmo Victor then was able to improve this to one picture every 2 seconds. Both of these utilized 9.6 bits per second condition telephone line. The effectiveness of Compressed T.V. Transmission as a detection tool was checked using speed measurement tests. The speed measurements determined from the image compression system were comparable with those made by an observer using a normal frame rate full resolution T.V. system. The positioning test clearly indicated the need for a supplementary system to aid in positioning the camera.
