Description
Dirac is an open source video codec, developed by BBC Research and Development. It uses motion estimation, wavelet transforms and arithmetic coding to obtain performance comparable with commercially available video codecs. Software implementation is available at http://dirac.sourceforge.net/
The Dirac Specification can be found in the docs section of the project CVS.

Status
- Fixed precision prototype of arithmetic coder and decoder available.
- Documentation added for fixed-probability prototype.
- Context-dependent prototype now available.
- Components for Exp-golomb encoding and decoding added.
- Adaptive encoding now implemented.
- Arithmetic coding and decoding bitwidths and exp-golomb data format converged to the Dirac specification. Arithmetic coding and decoding modules are now COMPLETE.
