Dynamic Markov compression — (DMC) is a lossless data compression algorithm developed by Gordon Cormack and Nigel Horspool [1]. It uses predictive arithmetic coding similar to prediction by partial matching (PPM), except that the input is predicted one bit at a time (rather… … Wikipedia
Lossless data compression — is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. The term lossless is in contrast to lossy data compression, which only allows an approximation of the original data to be… … Wikipedia
Audio compression (data) — For processes which reduce the amount of time it takes to listen to and understand a recording, see time compressed speech. Audio compression is a form of data compression designed to reduce the size of audio files. Audio compression algorithms… … Wikipedia
One-way compression function — In cryptography, a one way compression function is a function that transforms two fixed length inputs to an output of the same size as one of the inputs. The transformation is one way , meaning that it is difficult given a particular output to… … Wikipedia
Digital video — For other uses, see Digital video (disambiguation). Digital video is a type of digital recording system that works by using a digital rather than an analog video signal. The terms camera, video camera, and camcorder are used interchangeably in… … Wikipedia
Comparison of video codecs — A video codec is software or a device that provides encoding and decoding which may or may not include the use of video compression and/or decompression for digital video. The compression may employ lossy data compression, so quality measurement… … Wikipedia
