21MPEG-4 Audio Lossless Coding — MPEG 4 Audio Lossless Coding, auch bekannt unter MPEG 4 ALS, ist eine Erweiterung zum MPEG 4 Audio Standard um verlustfreie Audiodatenkompression zu ermöglichen. Die Entwicklung dieser Erweiterung wurde im Dezember 2005 abgeschlossen.… …
22Adaptive Transform Acoustic Coding — (ATRAC) est une technique de compression audio avec pertes développée par Sony en 1992 et utilisée notamment dans les appareils MiniDisc. Seul le ATRAC Advanced Lossless propose une compression sans pertes. Aujourd hui, le format ATRAC est… …
23Adaptive Huffman coding — (also called Dynamic Huffman coding) is an adaptive coding technique based on Huffman coding. It permits building the code as the symbols are being transmitted, having no initial knowledge of source distribution, that allows one pass encoding and …
24Context-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… …
25Modified Huffman coding — is used in fax machines to encode black on white images (bitmaps). It combines the variable length codes of Huffman coding with the coding of repetitive data in run length encoding. External links Modified Huffman coding from UNESCO . Archived… …
26Audio Lossless Coding — MPEG 4 Audio Lossless Coding, also known as MPEG 4 ALS, is an extension to the MPEG 4 audio standard to allow lossless audio compression. The extension was finalized in December 2005.MPEG 4 ALS is similar to FLAC in its operation. Simply put it… …
27Fractal transform — The fractal transform is a technique invented by Michael Barnsley et al. to perform lossy image compression.This first practical fractal compression system for digital images resembles a vector quantization system using the image itself as the… …
28Discrete transform — In signal processing, discrete transforms are mathematical transforms, often linear transforms, of signals between discrete domains, such as between discrete time and discrete frequency.[1] Many common integral transforms used in signal… …
29Adaptive Transform Acoustic Coding — ATRAC ist die Abkürzung für Adaptive Transform Acoustic Coding (in etwa: Anpassungsfähige Tonumwandlungskodierung) und stellt ein Audiodatenkompressionsverfahren dar. Inhaltsverzeichnis 1 Technik 1.1 Aufbau 1.2 Vergleich 1.3 …
30Superdense coding — is a technique used in quantum information theory to send two bits of classical information using only one qubit, with the aid of entanglement. Overview Suppose Alice would like to send classical information to Bob using qubits, instead of… …
