BBC (British Broadcasting Corporation) is working on an Open Source video codec. Many video codecs are proprietary, and this has been one of the limitations people observe when trying to operate with a completely free/libre computing platform.
The BBC seems to be doing quite a few publicly-minded projects, including their Creative Archive which will include content under Creative Commons licenses.
Canadians should ask: where is the CBC in this movement? (Hint: CBC download references a large number of proprietary vendors, including referencing proprietary codecs from RealNetworks and Apple for audio/video)
