11Huffman coding — Huffman tree generated from the exact frequencies of the text this is an example of a huffman tree . The frequencies and codes of each character are below. Encoding the sentence with this code requires 135 bits, as opposed of 288 bits if 36… …
12Advanced Audio Coding — AAC redirects here. For other uses, see AAC (disambiguation). Advanced Audio Codings iTunes standard AAC file icon Filename extension .m4a, .m4b, .m4p, .m4v, .m4r, .3gp, .mp4, .aac Internet media type audio/aac, audio/aacp, au …
13Distributed source coding — (DSC) is an important problem in information theory and communication. DSC problems regard the compression of multiple correlated information sources that do not communicate with each other.[1] By modeling the correlation between multiple sources …
14Non-coding RNA — A non coding RNA (ncRNA) is a functional RNA molecule that is not translated into a protein. Less frequently used synonyms are non protein coding RNA (npcRNA), non messenger RNA (nmRNA) and functional RNA (fRNA). The term small RNA (sRNA) is… …
15Algorithme de block-matching — Un algorithme de block matching ((en) Block Matching Algorithm) est une méthode utilisée pour encoder le mouvement dans une séquence vidéo en localisant des blocs similaires entre deux images. En compression vidéo, plusieurs normes vidéo telles… …
16Space-time block coding based transmit diversity — (STTD) is a method of transmit diversity used in UMTS third generation cellular systems. STTD is optional in the UTRAN air interface but mandatory for user equipment (UE). STTD utilizes space time block code (STBC) in order to exploit redundancy… …
17Advanced 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… …
18Audio 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… …
19Motion coding — is a technique that can be viewed as extensions of the standard block matching techniques in other MPEG standard to image sequences of arbitrary shape. Advanced motion compensation such as overlapped motion compensation and coding of motion… …
20Rate–distortion theory — is a major branch of information theory which provides the theoretical foundations for lossy data compression; it addresses the problem of determining the minimal amount of entropy (or information) R that should be communicated over a channel, so …
