There are actually several patents that are claimed BY the BBC, so  
that the BBC can defend the project against other companies sueing  
based on patent claims. In comparison to the other codecs the wavelet  
field holds much less claims overall however.

Also I saw the new versions and the Dirac hardware at IBC and was  
REALLY impressed. There has been made huge progress and visually it's  
almost on par with H.264
The problem is still the speed of course. It's one of the major  
reasons they are also working on hardware I guess.

I would like to point out the true commitment the BBC is making here.  
Many people don't seem to realize that the BBC has vowed to make  
their entire production chain Open Source wherever possible. If they  
have to by developing everything themselves. MXF/GXF/Dirac,  
streamingservers, video editing, directing/production metadata. It's  
all on their wishlist. It might take them another 5-10 years, but  
they truly seem to feel very strong about it. They are not forcing  
the issue of course. They replace something only when it is good  
enough or better to replace the proprietary stuff. But they are not  
sitting by waiting for the work to be done either. Of all the media  
companies, i'm starting to like the BBC best.
