"Coder-decoder " A device that converts analog video and audio signals into a digital format for transmission Also converts received digital signals back into analog format
Short for compressor/decompressor, a codec is any technology for compressing and decompressing data Codecs can be implemented in software, hardware, or a combination of both Some popular codecs for computer video include MPEG, Indeo and Cinepak In telecommunications, (short for coder/decoder) a device that encodes or decodes a signal For example, telephone companies use codecs to convert binary signals transmitted on their digital networks to analog signals converted on their analog networks The translation of a binary value into a voltage that can be transmitted over a wire
(1 coder/decoder) (n ) In communications engineering, integrated circuits or chips that convert data to be used in, for example, a modem A codec uses analog-to-digital conversion and digital-to-analog conversion in the same chip See decoder, encoder (2 compression/decompression) (n ) An algorithm or computer program for reducing byte consumption in large files and programs See data compression
A device or program capable of performing transformations on a data stream or signal
Device that converts analog voice signals into digital signals for transmission, and then reconverts them to the original voice form It can be in the telephone or part of the PBX
Coder/decoder Codecs convert data between uncompressed and compressed formats, reducing the bandwidth a clip consumes
Short for compressor/decompressor; a codec is any technology for compressing and decompressing data Codecs can be implemented in software, hardware, or a combination of both
Computing & media A COmpressor DECompressor is a piece of computer hardware or software used for the compression and/or decompression of digital media (most usually audio or video) The most common file formats created and read by CODECs include MP3 for compressed audio, and MPEG-1, MPEG-2, QuickTime-1 and M-JPEG for digital video
Compresses information so that it can be sent across a network faster, and decompresses information received via the network
Short for "compressor/decompressor"; refers to the hardware in a cell phone and in the cell network that compresses digitized voice prior to transmission AND takes received compressed voice and decompresses it prior to passing it to either a cell phone speaker or into a wireline system Codec allows the cell network to essentially pass a lot of data in compressed form to permit additional users on the system and to save bandwidth The idea behind codec is that human voices are highly lossy and a significant amount of the conversation can be removed since human ears can fill in the removed gaps at the other end Each technology has different codec algorithms -- for CDMA there is 13K and 8K
A coder-decoder that is used to convert analog signals such as video or voice into digital form for transmission over digital medium and, upon reception, reconverts the signals to the original analog form May also perform other signal processing functions: coder-decoder or compressor-decompressor (Novak)
Short for compressor/decompressor An algorithm or scheme used when recording digital video or audio A codec is used, for example, when video is transmitted over the Internet; the video is compressed on the sending end and decompressed on the receiving end Windows Media Tools provides a choice of codecs for ASF content Users can select a codec based on the audio or image quality, and image size preferred
(acronym for “COmpression/DECompression”) A specialized computer program used to reduce the size of large video and audio files Examples of common codecs are MPEG and Cinepak
a term used for a "code/decode" electrical device which converts an analog electrical signal into a digital form for transmission purposes It is generally used to transform video signals into digital form for transmission over digital transmission systems Generally speaking, this digital information must be reconverted into analog form at its point of reception
Codec stands for compression / decompression A codec is a small program that's installed on your computer which then allows Windows to compress and/or decompress audio to and from certain formats Codecs which allow for higher quality compression are available for download separate from any specific software program, but are not useful unless you have a program that supports that Codec For example, Blaze Audio RipEditBurn supports both the Fraunhofer and LAME codecs when creating MP3 files
Equipment used to transform analog voice signals to digital signals (coder) and digital signals to analog signals (decoder) May be in digital PABX or in the device/instrument itself
Acronym for coder-decoder 1 An assembly consisting of an encoder and a decoder in one piece of equipment (188) 2 A circuit that converts analog signals to digital code and vice versa 3 An electronic device that converts analog signals, such as video and voice signals, into digital form and compresses them to conserve bandwidth on a transmission path (188) Note: Codecs in this sense are used in this sense for video conferencing systems
Compression-Decompression Various CODECs exist to handle media, optimising the efficiency with which they are stored and delivered using compression and decompression technology A compressed file must be decompressed, or reinterpreted, before it can be delivered to the end user This process usually means loss of quality
Pertaining to adapters that compress and decompress video files The letters "CODEC" represent "compression/decompression"; in the past, they represented "coder/decoder "
