Abstract

This system is a unique development of apparatus and enabling software functionality specifically aimed at surveillance and monitoring activities and the statutes and administrative policies that govern them. The system incorporates video and audio capture devices and a conventional computer in which unique software functionality creates an authenticating evidentiary audit trail (frame-by-frame) during an optimal compression process while presenting a live view of the captured video data. This unique and uniquely combined process directly supports many public safety and other security operations with their need for a live monitoring view and a minimum capacity storage archive. The unique data construct also allows for such inventive features as a graphical content catalog to aid in finding captured video and/or audio, the evidentiary analysis functionality of variable speed forward and backward playback and a fully managed storage and distribution sub-system again with incorporated audit and activity tracking.

Claims

1. A method for measuring digital data and creating data files which can be:

uniquely authenticated, enable a usage audit, enable efficient mobile wireless distribution, enable interchangeable component (audio and video) playback and enable redaction without changing the data comprising a means for;

a) receiving digital data;

b) determining a measurement calculus for the digital data at a point in time; and

c) packing the digital data into files representing equally sized blocks of time, such that all of the blocks of time start and stop at the same time across the entire system.

2. the method in claim 1 where the digital data is video data;

3. the method in claim 1 where the digital data is audio data;

4. the method in claim 1 where the digital data is video data and audio data;

5. the method in claim 1 where the means for receiving comprises any microprocessor or computer;

6. the method in claim 1 where the measurement calculus applied to the digital data is calculated using an in-line mathematical process by a custom software developed for the inventive system;

7. the custom software in claim 6 creates a single datum or numerical representation for a point in time based on one or more of the component representations of the digital data;

8. the custom software in claim 6 creates a datum or numerical representation as an adjunct component process to a data compression process and a data packaging process which are done as an in-line continuing mathematical process;

9. the in-line mathematical process in claim 6 is managed by the custom software in claim 6 to efficiently package the data and the related or corresponding datum so that the files produced always cover the same unit of time, even if the digital data stream is stopped or started several times within the block of time;

10. the custom software in claim 6 can be applied during decompression to play the video data generating another datum providing a basis for comparison and the authentication of the video data at delivery;

11. the custom software in claim 6 can be applied during decompression and play of the audio data providing a basis for comparison and the authentication of the audio data at delivery;

12. the custom software in claim 6 allows reintegration of time blocks to continuous video data in claim 10 providing an opportunity for a usage audit to be taken;

13. the custom software in claim 6 allows reintegration of time blocks to continuous audio data in claim 11 providing an opportunity for a usage audit to be taken;

14. the usage audit in claim 12 or claim 13 can be fed into a database for the creation of an historical record of usage;

15. the custom software in claim 6 allows input of digital data from a plurality of sources for any time block allowing confirmation of the time sequence of activities monitored by separate recording devices;

16. the datum or numerical representation in claim 7 for video data is determined by the brightness and color of each pixel over all of the pixels in a frame, the frame representing the video sample at a point in time;

17. the datum or numerical representation in claim 7 for video data is determined by the brightness of each pixel over all of the pixels in a frame, the frame representing the video sample at a point in time;

18. the datum or numerical representation in claim 7 for video data is determined by the color of each pixel over all the pixels in a frame, the frame representing the video sample at a point in time;

19. the datum or numerical representation in claim 7 for audio data is determined by the amplitude of each frequency in the sample taken at a point in time.
