Techniques For Converting Analog Data To Digital Format For Film Or Television Annotation
D. L. Trone · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1982
Data Acquisition Systems interface between the real world of physical parameters, which are analog, and the artificial digital world. When the analog world is recorded digitally on film or video tape, analog parameters such as speed, azmiuth, elevation, pitch/roll and time can be converted to digital information and recorded on film or video tape along with a "picture" of the event. This paper provides an overview of some of the techniques of converting the analog data to digital information for annotation purposes.
