"In January 2003, BBC R&D produced a prototype video coding algorithm, based on wavelet technology, which is different from that used in the main proprietary or standard video compression systems. Our algorithm seems to give a two-fold reduction in bit rate over MPEG-2 for high definition video (e.g. 1920x1080 pixels), its original target application. It has been further developed to optimise it for internet streaming resolutions and seems broadly competitive with state of the art video codecs."
"At the moment the codec, called Dirac, is in the early stages of development. It has been developed as a research tool, not a product, as a basis for further developments. An experimental version of the code, written in C++, was released under an Open Source licence agreement on 11th March at http://sourceforge.net/."
