Transcode: Conversion of an audio or video data file from one form of encoding to another. Usually, an audio or video data file is transcoded in order to create a new instantiation in a format differing from the original for access or preservation purposes. Since “transcoding” involves re-encoding, it commonly introduces loss or degradation in the audible or visual signal when a “lossycodec is deployed. However, using a “lossless” codec such as JPEG2000 for video enables transcoding without degradation of visual information. [ Audio Glossary ] [ Video Glossary ] [ Archive Glossary ]
