BBC Dirac Video Codec

Experimental Open Source video codec. It aims to be a substitute for the famous MPEG2, used mainly in DVDs.
It should perform twice better than MPEG2 (50 per cent of the bandwidth used). Is designed as a conventional hybrid motion-compensated codec, except that the the function normally performed by a block transform in most MPEG standard and proprietary codecs is instead performed by the wavelet transform.
