There are many such contracts and they are confidential, so unfortunately I can't post them. > It doesn't make sense to discuss potential > solutions to requirements if those requirements aren't clear. > As far as I understand, the way things work today is that it is the DRM vendors who take on the task of creating solutions that meet the requirements of the studios and of getting buy-in from the studios that their solutions do indeed meet the requirements. You can look, for example, at the PlayReady robustness rules for an example of the result: http://www.microsoft.com/playready/licensing/compliance/ Realistically, I don't think you will get studio requirements posted publicly, but that's not a question for me. So, the DRM vendors have solved the problem of creating solutions that meet studio requirements and what we are trying to do with EME is provide a clean API to integrate these solutions with the HTML Media Element. What we're not trying to do is standardize a solution to the studio requirements. That would be rather ambitious, I feel. ...Mark > > -- > Duncan Bayne > ph: +61 420817082 | web: http://duncan-bayne.github.com/ | skype: > duncan_bayne > > I usually check my mail every 24 - 48 hours.
