Viterbi decoder. A 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 ...
Forms terms denoting conditions relating to eating or ingestion Greek φαγία (phagía) eating < φᾰγεῖν (phageîn), to eat Sarcophagia-phago-eating, devouring Greek -φᾰ́γος (-phágos), eater of, eating phagocyte: phagist-Forms nouns that denote a person who 'feeds on' the first element or part of the word
In information technology, lossy compression or irreversible compression is the class of data compression methods that uses inexact approximations and partial data discarding to represent the content. These techniques are used to reduce data size for storing, handling, and transmitting content. The different versions of the photo of the cat on ...
Decodable text is a type of text often used in beginning reading instruction. Decodable texts are carefully sequenced to progressively incorporate words that are consistent with the letters and corresponding phonemes that have been taught to the new reader. Therefore, with this type of text new readers can decipher words using the phonics ...
The Viterbi algorithm is a dynamic programming algorithm for obtaining the maximum a posteriori probability estimate of the most likely sequence of hidden states—called the Viterbi path —that results in a sequence of observed events. This is done especially in the context of Markov information sources and hidden Markov models (HMM).
Transcoding. Transcoding is the direct digital-to-digital conversion of one encoding to another, [1] such as for video data files, audio files (e.g., MP3, WAV ), or character encoding (e.g., UTF-8, ISO/IEC 8859 ). This is usually done in cases where a target device (or workflow) does not support the format or has limited storage capacity that ...
An audio coding format [1] (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 ...
Data compression. In information theory, data compression, source coding, [1] or bit-rate reduction is the process of encoding information using fewer bits than the original representation. [2] Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy.
