The Pentagon’s Tivo

To counter these new threats, technology exists, or could be developed, to provide new levels of spatial, temporal, and spectral resolution and diversity. Furthermore, the ability to record terabyte and larger databases will provide an omnipresent knowledge of the present and the past that can be used to rewind battle space observations in TiVo-like fashion and to run recorded time backwards to help identify and locate even low-level enemy forces. For example, after a car bomb detonates, one would have the ability to play high-resolution data backward in time to follows the vehicle back to the source, and then use that knowledge to focus collection and gain additional information by organizing and searching through archived data.
