| codec As
the name implies, codecs are used to encode and decode (or compress and
decompress) various types of data--particularly those that would otherwise
use up inordinate amounts of disk space, such as sound and video files.
Common codecs include those for converting analog video signals into
compressed video files (such as MPEG) or analog sound signals into into
digitized sound (such as RealAudio). Codecs can be used with either
streaming (live video or audio) or files-based (AVI, WAV) content. |
