Abstract (en)

[origin: WO2005122439A1] A method of generating a composite delta file based on the differences between an original file and an upgraded file. The method comprises the steps of: 1) segmenting the original binary file into segments of size N; 2) segmenting the upgraded binary file into segments of size N; 3) detecting a first set of differences between a first segment from the original binary file and a first segment from the upgraded binary file; and 4) generating a first delta file from the detected first set of differences. The method further comprises the steps of: 4) detecting a second set of differences between a second segment from the original binary file and a second segment from the upgraded binary file; and 5) generating a second delta file from the detected second set of differences. The first and second delta files are combined to form the composite delta file.
