Abstract
Abstract The present invention provides a method for loss-less compression of full motion video by utilizing the redundancy between a greater number of frames than in the prior art. Each frame is analyzed for a characteristic of change and only the change information is stored throughout the sequence of frames. Knowledge of future frames is also utilized to store base information in a library for use with the future frames.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
44 words
A method of compressing a digitized video, comprising the steps of: determining characteristics of change from a first frame of video to subsequent frames of video in a video scene; and providing instructions for encoding said subsequent frames based upon said characteristics of change.
Claim 2
Dependent Claim
29 words
The method of Claim 1, wherein said step of determining comprises analyzing said frames for localized, linear, angular, random, historical and part of scene exposed from previous frame change.
Claim 3
Dependent Claim
31 words
The method of Claim 1 or 2, wherein said step of providing instructions comprises giving a location of change and a number of frames if said characteristic is said localized change.
Claim 4
Independent Claim
41 words
The method of any of the preceding Claims, wherein said step of providing instructions comprises providing beginning coordinates, direction, incremental movement of a set of blocks comprising an object and maximum number of frames if said characteristic is said linear change.
Claim 5
Independent Claim
34 words
The method of any of the preceding Claims, wherein said step of providing instructions comprises providing beginning coordinates, radius, center, angular velocity and maximum number of frames if said characteristic is said angular change.
Claim 6
Independent Claim
34 words
The method of any of the preceding Claims, wherein said step of providing instructions comprises providing a sequence of coordinates for a maximum number of consecutive frames if said characteristic is said random change.
Claim 7
Independent Claim
38 words
The method of any of the preceding Claims, wherein said step of providing instructions comprises providing instructions to create re-exposed part from a previous frame if said characteristic is said part of scene exposed from previous frame change.
Claim 8
Independent Claim
35 words
The method of any of the preceding Claims, wherein said step of providing instructions comprises providing instructions to locate frame in a library of scenes plus any change if said characteristic is said historical change.
Claim 9
Independent Claim
25 words
The method of any of the preceding Claims, further comprising the step of decoding said instructions to reconstruct said digitized video into an analog video.
Claim 10
Independent Claim
30 words
The method of reducing storage space required for a digitized video, comprising the step of encoding only a change from previous frames in each frame of a plurality of frames.
Claim 11
Independent Claim
45 words
A system for compressing a digitized video, comprising means for determining characteristics of change from a first frame of video to subsequent frames of video in a video scene; and means for providing instructions for encoding said subsequent frames based upon said characteristics of change.
Claim 12
Dependent Claim
31 words
The system of Claim 11, wherein said means for determining comprises means for analyzing said frames for localized, linear, angular, random, historical and part of scene exposed from previous frame change.
Claim 13
Dependent Claim
33 words
The system of Claim 11 or 12, wherein said means for providing instructions comprises means for giving a location of change and a number of frames if said characteristic is said localized change.
Claim 14
Independent Claim
42 words
The system of any of Claims 11-13, wherein said means for providing instructions comprises means for providing beginning coordinates, direction, incremental movement of a set of blocks comprising an object and maximum number of frames if said characteristic is said linear change.
Claim 15
Independent Claim
35 words
The system of any of Claims 11-14, wherein said means for providing instructions comprises means for providing beginning coordinates, radius, center, angular velocity and maximum number of frames if said characteristic is said angular change.
Claim 16
Independent Claim
35 words
The system of any of Claims 11-15, wherein said means for providing instructions comprises means for providing a sequence of coordinates for a maximum number of consecutive frames if said characteristic is said random change.
Claim 17
Independent Claim
39 words
The system of any of Claims 11-16, wherein said means for providing instructions comprises means for providing instructions to create re-exposed part from a previous frame if said characteristic is said part of scene exposed from previous frame change.
Claim 18
Independent Claim
36 words
The system of any of Claims 11-17, wherein said means for providing instructions comprises means for providing instructions to locate frame in a library of scenes plus any change if said characteristic is said historical change.
Claim 19
Independent Claim
26 words
The system of any of Claims 11-18, further comprising the step of means for decoding said instructions to reconstruct said digitized video into an analog video.
