Adaptive Spectral Perceptual Entropy Coding — (ASPEC) ist ein Verfahren zur Datenkompression von Audiosignalen, bei denen unter anderem pyschoakustische Modelle angewandt werden. Das Verfahren ist Basis von Advanced Audio Coding (AAC), AC 3 und MP 3. Literatur Thomas Görne: Tontechnik. 1.… … Deutsch Wikipedia
Entropy encoding — In information theory an entropy encoding is a lossless data compression scheme that is independent of the specific characteristics of the medium. One of the main types of entropy coding creates and assigns a unique prefix free code to each… … Wikipedia
Coding theory — is the study of the properties of codes and their fitness for a specific application. Codes are used for data compression, cryptography, error correction and more recently also for network coding. Codes are studied by various scientific… … Wikipedia
Coding — may refer to: Channel coding in coding theory Line coding Computer programming, the process of designing, writing, testing, debugging / troubleshooting, and maintaining the source code of computer programs The process of Statistical… … Wikipedia
Entropy (information theory) — In information theory, entropy is a measure of the uncertainty associated with a random variable. The term by itself in this context usually refers to the Shannon entropy, which quantifies, in the sense of an expected value, the information… … Wikipedia
Golomb coding — is a data compression scheme invented by Solomon W. Golomb in the 1960s. The scheme is based on entropy encoding and is optimal (in the sense of Shannon s source coding theorem) for alphabets following a geometric distribution, making it highly… … Wikipedia
Context-adaptive variable-length coding — (CAVLC) is a form of entropy coding used in H.264/MPEG 4 AVC video encoding. It is an inherently lossless compression technique, like almost all entropy coders. In H.264/MPEG 4 AVC, it is used to encode residual, zig zag order, blocks of… … Wikipedia
Context-adaptive binary arithmetic coding — (CABAC) is a form of entropy coding used in H.264/MPEG 4 AVC video encoding. It is a lossless compression technique. It is notable for providing much better compression than most other encoding algorithms used in video encoding, and is one of the … Wikipedia
Advanced Video Coding — H.264/MPEG 4 AVC ist ein Standard zur hocheffizienten Videokompression. Er wurde zunächst von der ITU (Study Group 16, Video Coding Experts Group) unter dem Namen H.26L entwickelt. Im Jahre 2001 schloss sich die ITU Gruppe mit MPEG Visual… … Deutsch Wikipedia
Scalable Video Coding — (SVC) is the name given to an extension of the H.264/MPEG 4 AVC video compression standard. H.264/MPEG 4 AVC was developed jointly by ITU T and ISO/IEC JTC 1. These two groups created the Joint Video Team (JVT) to develop the H.264/MPEG 4 AVC… … Wikipedia
Exponential-Golomb coding — An Exponential Golomb code (or just Exp Golomb code) of order k is a type of universal code, parameterized by a whole number k. To encode a nonnegative integer in an order k exp Golomb code, one can use the following method: # Take the number in… … Wikipedia
