A decoder is a device which does the reverse of an encoder, undoing the encoding so that the original information can be retrieved. The same method used to encode is usually just reversed in order to decode. An encoder is a device used to encode a bitstream or other signal or data into a form that is acceptable for transmission or storage. ...
The word encoding has a number of meanings. ...
For other senses of the word code, see code (disambiguation). ...
An endec is a device which both encodes and decodes, either with the same or separate circuitry or algorithm. The combining of these names is a portmanteau. A portmanteau (plural: portmanteaux or portmanteaus) is a word that is formed by combining two words. ...
The general difference between an endec and a codec is that hardware is usually considered to be an endec, while software is considered to be the codec. Similarly, the word "encoding" is usually used for hardware, while "coding" is usually used in regards to software. Codec is a portmanteau of coder/decoder, which describes a device or program capable of performing transformations on a data stream or signal. ...
Hardware is equipment such as fasteners, keys, locks, hinges, wire, chains, plumbing supplies, tools, utensils, cutlery and machine parts, especially when they are made of metal. ...
The term coding has the following meanings: In communications systems, the altering of the characteristics of a signal to make the signal more suitable for an intended application, such as optimizing the signal for transmission, improving transmission quality and fidelity, modifying the signal spectrum, increasing the information content, providing error...
A program (or hardware) which uses a compression algorithm to create MPEG audio and/or video is often called an encoder, and one which plays back such files is a decoder. However, this is technically a codec, especially if performed in software. Hardware is equipment such as fasteners, keys, locks, hinges, wire, chains, plumbing supplies, tools, utensils, cutlery and machine parts, especially when they are made of metal. ...
In computer science, data compression or source coding is the process of encoding information using fewer bits, or information units, thanks to specific encoding schemes. ...
The Moving Picture Experts Group (MPEG) is a small group charged with the development of video and audio encoding standards. ...
Audio can mean: sound that can be heard electronics or other signals of frequencies audible to humans (about 20__20,000 Hz) broadcasting or reception of sound high_fidelity sound reproduction sound recording and reproduction in general I hear in Latin This is a disambiguation page — a navigational aid which lists other...
Video is the technology of processing electronic signals representing moving pictures. ...
Computer software (or simply software) refers to one or more computer programs and data held in the storage of a computer for some purpose. ...
Examples of encoders, decoders, and endecs:
Other things which are encoded or decoded: A modem (a portmanteau word constructed from modulator and demodulator) is a device that modulates an analog carrier signal (sound), to encode digital information, and that also demodulates such a carrier signal to decode the transmitted information. ...
For the musical use of modulation, see modulation (music). ...
A Demodulator is an electronic circuit used to recover the information content from the carrier wave of a signal. ...
The Emergency Alert System (EAS), is a national system in the U.S. put into place in 1997, superseding the Emergency Broadcast System and administered by the Federal Communications Commission (FCC). ...
A stereo generator is an electronic device designed to encode stereophonic information for transmission over radio or television. ...
Note: broadcasting is also the old term for hand sowing. ...
