Method and apparatus for storing digital video content provided from a plurality of cameras
First Claim
Patent Images
1. A method of providing for digital data storage of a stream of image data and pattern recognition of at least one external pattern and an initially compressed external pattern on the stream of image data comprising the steps of:
- compressing a stream of digital image data using at least a first thread to obtain an initially compressed stream of digital image data and performing pattern recognition using the at least one external pattern and at least a second thread to attempt to recognize matches, the first and second threads being processed using a processing system;
transmitting the initially compressed stream of digital image data to another processing system; and
further compressing the initially compressed stream of digital image data using at least a third thread to obtain a further compressed stream of digital image data and performing pattern recognition of the at least one external pattern using at least a fourth thread and the initially compressed external pattern to attempt to recognize matches, the third and fourth threads being processed using the another processing system.

Abstract
The present invention provides a distributed surveillance system that allows for the digital storage of data, as well as the recognition of external patterns obtained in parallel operations. Further, digital data can be stored at different levels of compression, and pattern recognition achieved while the digital data is still in its compressed form.
