Abstract

A system for automatically providing event non-video information usable for indexing event video information, where the event takes place at an event location for a duration of event time. The system includes a non-video information system for receiving or determining event non-video information and storing the non-video information in a non-video dataset, a video information system for receiving event video information captured by one or more filming cameras and storing the video information in a video dataset, and a video information retrieval system for randomly accessing the video dataset, where the random access includes: (a) using event non-video information to first determine an event time or duration of event time, and (b) using the determined event time or duration of event time to selectively access, retrieve, or provide event video information including one or more video images of the event.
