Audio coding formatAn audio coding format (or sometimes audio compression format) is a content representation format for storage or transmission of digital audio (such as in digital television, digital radio and in audio and video files). Examples of audio coding formats include MP3, AAC, Vorbis, FLAC, and Opus. A specific software or hardware implementation capable of audio compression and decompression to/from a specific audio coding format is called an audio codec; an example of an audio codec is LAME, which is one of several different codecs which implements encoding and decoding audio in the MP3 audio coding format in software.
Viterbi decoderA Viterbi decoder uses the Viterbi algorithm for decoding a bitstream that has been encoded using a convolutional code or trellis code. There are other algorithms for decoding a convolutionally encoded stream (for example, the Fano algorithm). The Viterbi algorithm is the most resource-consuming, but it does the maximum likelihood decoding. It is most often used for decoding convolutional codes with constraint lengths k≤3, but values up to k=15 are used in practice. Viterbi decoding was developed by Andrew J.
Z-bufferthumb|Contenu d'un Z-Buffer En infographie, le Z-buffer ou tampon de profondeur est une méthode employée dans le cadre de l'affichage d'une scène 3D. Le Z-Buffer permet de gérer le problème de la visibilité qui consiste à déterminer quels éléments de la scène doivent être rendus, lesquels sont cachés par d'autres et dans quel ordre l'affichage des primitives doit se faire. Il est principalement utilisé par l'accélération matérielle de la 3D, mais l'est aussi dans beaucoup de moteurs 3D logiciels.
