Method and apparatus for segmented video compression
First Claim
Patent Images
1. A video recording apparatus comprising:
- image receiving circuitry for receiving electronic images;
storage means;
processing circuitry, coupled to the image receiving circuitry and the storage means, for;
receiving a current image from the image receiving circuitry at a specified index;
allocating the current image to a plurality of predefined sectors each containing a predefined sector image that is a portion of the current image;
for each of a plurality of the predefined sector images;
comparing the predefined sector image with a plurality of previously generated profile sector images stored in the storage means;
determining whether the predefined sector image matches a profile sector image within a predetermined threshold; and
associating the index and a plurality of the predefined sectors with profile sector images that match the predefined sector images of the plurality of predefined sectors within the predetermined threshold.

Abstract
An archival video system uses profile images as a background for an image and delta images to indicate the difference between a current image and a profile image. An image may be segmented into multiple sectors, with each sector compared to a profile sector. The resulting image may be constructed using references to previously stored sectors from different images.
