Compression (Coding) is basically the process of removal of redundancy in the digital video signal. Compression techniques (Coding of video signals) can be classified as Source coding and Entropy coding. Source coding deals with the source material (video input) and yields lossy results where the picture quality gets degraded on reproduction of video during playback. Entropy coding uses the statistical property of video signals. In theory, it is a lossless coding technique, which do not yields in the loss of video signals on reproduction.
