Video event capturing system and method
First Claim
1. A process monitoring and event capturing system, comprising:
- (a) at least one video detector for monitoring a process and outputting a video signal and at least one event signal representing an event condition of the process being monitored;
(b) a recorder for recording the video signal and the event signal in a digital video file of a digital storage device having a predetermined data structure, the video file comprising;
(i) a file header at the front of the file for identifying the file format of the video file;
(ii) a plurality of chunk headers for identifying the beginning and end of a plurality of frame segments within the video file for storing the video signal; and
(iii) at least one event feature data structure at the end of the video file for storing the event signal representative of the captured event condition.

Abstract
A process monitoring and event capturing system, including at least one video detector for monitoring a process and outputting a video signal and at least one event signal representing an event condition of the process being monitored. A recorder records the video signal and the event signal in a digital video file of a digital storage device having a predetermined data structure. The video file is structured to include at least one event feature data structure at the end of the video file for storing the event signal representative of the captured event condition. The digital storage device includes a temporary data file for storing video segments for examination by the user. The file format structure stores event data from the end of the data file forward in reverse order, permitting additions of data without affecting the previous file structure.
