51Dictionary coder — A dictionary coder, also sometimes known as a substitution coder, is a class of lossless data compression algorithms which operate by searching for matches between the text to be compressed and a set of strings contained in a data structure… …
52Gray code — The reflected binary code, also known as Gray code after Frank Gray, is a binary numeral system where two successive values differ in only one digit.The reflected binary code was originally designed to prevent spurious output from… …
53Comparison of video codecs — A video codec is software or a device that provides encoding and decoding which may or may not include the use of video compression and/or decompression for digital video. The compression may employ lossy data compression, so quality measurement… …
54TurboGrafx-16 — TurboGrafx 16/PC Engine From Top to Bottom, The North American/UK design and the Japanese Design …
55Comparison of audio formats — The following tables compare general and technical information for a variety of audio formats and audio compression formats. For listening tests comparing the perceived audio quality of audio formats and codecs, see the article Codec listening… …
56Lempel-Ziv-Welch — (LZW) is a universal lossless data compression algorithm created by Abraham Lempel, Jacob Ziv, and Terry Welch. It was published by Welch in 1984 as an improved implementation of the LZ78 algorithm published by Lempel and Ziv in 1978. The… …
57Variable bitrate — (VBR) is a term used in telecommunications and computing that relates to the bitrate used in sound or video encoding. As opposed to constant bitrate (CBR), VBR files vary the amount of output data per time segment. VBR allows a higher bitrate… …
58Shannon's source coding theorem — In information theory, Shannon s source coding theorem (or noiseless coding theorem) establishes the limits to possible data compression, and the operational meaning of the Shannon entropy.The source coding theorem shows that (in the limit, as… …
59Consumer IR — Consumer IR, consumer infrared, or CIR, refers to a wide variety of devices employing the infrared electromagnetic spectrum for wireless communications. Most commonly found in television remote controls, infrared ports are equally ubiquitous in… …
60Differential coding — In digital communications, differential coding is a technique used to provide unambiguous signal reception when using some types of modulation. It makes data to be transmitted to depend not only on the current bit (or symbol), but also on the… …
