A codec encodes a data stream or signal for transmission, storage or [|encryption], or decodes it for play-back or editing. Codecs are used in video-conferencing, streaming media and video editing applications. A video camera's [|analog-to-digital converter (ADC)] converts its analog signals into digital signals, which are then passed through a video compressor for digital transmission or storage. A receiving device then runs the signal through a video decompressor, then a [|digital-to-analog converter (DAC)] for analog display. The term //codec// is also used as a generic name for a video conferencing unit. There are two different kids of compression quality for a codec, lossless and lossy codecs. Many of the more popular codecs in the software world are lossy, meaning that they reduce quality by some amount in order to achieve compression. Often, this type of compression is virtually indistinguishable from the original uncompressed sound or images, depending on the codec and the settings used. There are also many lossless codecs which are typically used for archiving data in a compressed form while retaining all of the information present in the original stream. Lossless codecs preserve the original quality of the stream and is more important than eliminating the correspondingly larger data sizes(Source: wikipedia.org) media type="custom" key="12120208"media type="custom" key="12198090"media type="googlemap" key="http://maps.google.com/maps/ms?ll=39.27479,-77.167969&spn=2.942527,4.916382&t=m&z=8&msa=0&msid=217988915226915527669.0004b7e7ba7aadf7599df" width="425" height="350"
