Abstract
A computer-based method for generating a compressed data stream, including using a specially programmed computer to: access a first compressed data stream including a first plurality of sequentially arranged frames including respective compressed frame data; access a second compressed data stream including a second plurality of sequentially arranged frames including respective compressed frame data; compare respective compressed data for sequentially matched pairs of frames in the first and second pluralities of frames; select, based on the comparison, common and unique portions in the first data stream; and select, based on the comparison, first and second portions in the second data stream, matched with the common and unique portions, respectively, in the sequence. The first portion has respective compressed frame data equal to the respective compressed frame data for the common portion. The second portion has respective compressed frame data unequal to the respective compressed frame data for the common portion.
