BBC's Plan To Kick Open Source Out of UK TV
bluec writes "Generally speaking, the BBC isn't allowed to encrypt or restrict its broadcasts: the license fee payer pays for these broadcasts. But the BBC has tried to get around this, asking Ofcom for permission to encrypt the 'metadata' on its broadcasts – including the assistive information used by deaf and blind people and the 'tables' used by receivers to play back the video. As Ofcom gears up to a second consultation on the issue, there's one important question that the BBC must answer if the implications of this move are to be fully explored, namely: How can free/open source software co-exist with a plan to put DRM on broadcasts?"
However, the BBC would like to collaborate with the Open Source community, academics and others to produce an Open Codec
you're not going to see any open source DRM systems any time soon.
While I can't be clear on their efficacy, it would be incorrect to say there are no DRM systems available.
