Jason: Should include background info in Content Protection doc on MPTF page

Clarke: 2nd bullet - Content protection must specify rights in Content Protection agreements
... Various parties in CP agreements
... Working through rights for parties

Joe: CP protection must be implementable in open browsers?

Clarke: Change requirement to should (from must)

<glenn> may be difficult to define "open browser"

Clarke: CP system must not advantage one method over another
... DTCP vs IP

Jason: Agnostic to CP method
... We're not providing CP system

Jason: APIs should not advantage one particular method

Clarke: Should have baseline method

Jason: Why make baseline method mandatory?
... Clear-key is mandatory method

Joe: we should have a mandatory method, whether or not paid SPs will use it

Clarke: Additional comment on baseline method?

MarkW: Change required to recommended?
... Unwise to mandate method

Clarke: Change to should?

MarkW: OpenSource implementation a requirement?

Clarke: May want to consider later?

mav: CP solutions must work with OpenSource browsers?

MarkW: Don't need whole system implementable in OpenSource browsers

<glenn> in other words, the basic mechanism should be implementable in O/S, but specific CDM implementations may not be implementable, due to technical or licensing reasons

Clarke: Changed wording CP methods miust work with OpenSource browsers (vs implementable in)

mav: Must address HTML5 features

Clarke: CP must be usable in HTML5
... Must be usable w/TimedTracks etc

Jason: Must or Should?

?: Feature should be covered by CP when available

acolwell: Copying to Canvas disable for protected content?

<glenn> need to distinguish between features available during encryption vs features available during copy protection/drm regime; they may be different

Clarke: Other discussion?
... Added link for Adaptive Bit Rate

Aaron: Working with MarkW

Clarke: Closing meeting
... See folks on HTML5 call
