Automatic extraction of secondary video streams
First Claim
Patent Images
1. A system to automatically generate a secondary video stream based on an incoming primary video stream, the system comprising:
- a computer configured to;
perform video analytics on the primary video stream to generate one or more analysis results, the one or more analysis results including information relating to first and second targets of interest;
detect the first and second targets of interest using the analysis results, and determine the first and second targets of interest are moving targets;
automatically extract a first secondary video stream from the primary video stream, the first secondary video stream capturing at least a portion of each of the first and second targets of interest in motion, the first secondary stream having a field of view smaller than a field of view of the primary video stream;
track the first and second targets of interest; and
display the first secondary stream including the at least the portion of each of the first and second targets of interest in motion.

Abstract
The automatic generation of one or more secondary video streams based on an input primary video stream may use analytics performed on the video to provide information on targets, events, and/or areas of interest to permit the one or more secondary video streams to concentrate on one or more targets, events and/or areas of interest.

23. A computer-implemented method of automatically generating a secondary video stream based on an incoming primary video stream, comprising:
-
performing video analytics on the primary video stream to generate one or more analysis results, the one or more analysis results including information relating to first and second targets of interest; detecting the first and second targets of interest using the analysis results, and determining the first and second targets of interest are moving targets; automatically extracting a first secondary video stream from the primary video stream, the first secondary video stream capturing at least a portion of each of the first and second targets of interest in motion, the first secondary video stream having a smaller than a field of view of the primary video stream; tracking the first and second targets of interest; and displaying the first secondary video stream including the at least the portion of each of the first and second targets of interest in motion.
