Google refers to delta updates as "smart updates." This has been implemented in Google's Android operating system devices that run on Android 2.3 or above. Google engineers have estimated that smart updates would be only about one third the size of a full update on average.
Delta Debugging has been applied to isolate failure-inducing program input (e.g. an HTML page that makes a Web browser fail), failure-inducing user interaction (e.g. the keystrokes that make a program crash), or failure-inducing changes to the program code (e.g. after a failing regression test).
Xdelta [3] is a command line tool for delta encoding, which stores or transmits the difference (deltas) between sequential data, instead of entire files.This is similar to diff and patch, except diff computes and shows the difference between two complete files, while patch is primarily designed for human-readable text files; Xdelta is designed for binary files and does not generate human ...
Delta encoding is a way of storing or transmitting data in the form of differences (deltas) between sequential data rather than complete files; more generally this is known as data differencing. Delta encoding is sometimes called delta compression, particularly where archival histories of changes are required (e.g., in revision control software).
VCDIFF is a format and an algorithm for delta encoding, described in IETF's RFC 3284.The algorithm is based on Jon Bentley and Douglas McIlroy's paper "Data Compression Using Long Common Strings" [1] written in 1999.
Binary delta compression is a technology used in software deployment for distributing patches. Explanation
The output is called a "diff", or a patch, since the output can be applied with the Unix program patch. The output of similar file comparison utilities is also called a "diff"; like the use of the word " grep " for describing the act of searching, the word diff became a generic term for calculating data difference and the results thereof.
