Abstract

A surveillance system having a plurality of MPEG compressed data streams each originating from a separate video/audio source. The data is streamed onto a plurality of media of different type in real time. The plurality of media are selected from the group consisting of: a digital tape, a hard disk, a semiconductor memory, a CVD, a DVD, and an optical disk. The system generates directory information which is also stored on a plurality of different media.

Claims

1. A mobile video surveillance system, comprising:

a source of a video signal, said source carried by a mobile vehicle;

a video signal compression system carried by said mobile vehicle and electrically connected to said source and providing a compressed video signal;

a plurality of digital storage media carried by said mobile vehicle, said plurality of digital storage media selected from the group consisting of;

a digital tape, a hard disk, a semiconductor memory, a CVD, a DVD, and an optical disk; and

a digital recording system carried by said mobile vehicle and communicating with said compression system for writing said compressed video signal to said plurality of digital storage media.

2. A mobile video surveillance system as in claim 1 wherein one of said digital storage media is a digital tape.

3. A mobile video surveillance system as in claim 1 wherein one of said digital storage media is a hard disk.

4. A mobile video surveillance system as in claim 1 wherein one of said digital storage media is a solid state memory.

5. A mobile video surveillance system as in claim 1 wherein said compression system is an MPEG compression system.

6. A mobile video surveillance system as in claim 5 wherein said video compression is selected from the group consisting of MPEG-1, MPEG-2, MPEG-4, and H.264.

7. A mobile video surveillance system as in claim 1 wherein said video signals are high density (HD) video signals.

8. A mobile video surveillance system as in claim 1 and further including a directory generator for generating directory information, and wherein said directory information is written into each of said plurality of storage media.

9. A mobile video surveillance system as in claim 8 wherein said digital medium is a tape cassette, said tape cassette has a solid state memory incorporated into it, and said directory information is contained in said sold state memory.

10. A method of mobile video surveillance, said method comprising:

providing on a mobile vehicle a video source producing a video signal;

compressing said video signal at said mobile vehicle to form a stream of compressed video data; and

recording said stream of compressed video data to a first recording medium and to a second recording medium on said mobile vehicle;

wherein said first recording medium is a different type of recording medium than said second recording medium.

11. A method as in claim 10 wherein said recording comprises recording to a digital tape and recording to either a semiconductor memory or a hard drive.

12. A method of video surveillance as in claim 10 wherein said recording comprises recording to a semiconductor memory.

13. A method of video surveillance as in claim 12 wherein said semiconductor memory is selected from Flash memory or FeRAM memory.

14. A method of video surveillance as in claim 10 wherein said compressing is selected from the group consisting of MPEG-1, MPEG-2, MPEG-4, and H.264 compression.

15. A method of video surveillance as in claim 10 wherein said video signal is a high density (HD) video signal.

16. A method of video surveillance as in claim 10 wherein said recording comprises recording to a tape cassette having a solid state memory incorporated into it, and said method further comprises writing directory information regarding said compressed video signal into said solid state memory.

17. A method of video surveillance as in claim 10 wherein said recording said video data comprises recording to a third recording medium different from said first and second recording media.
