Re: WAVE Project liaison on Commercial DRM Testing

Hi François, all,

Sorry it's taken so long to follow up on this. I've just replied to our CTA WAVE contacts to invite more detail regarding the practical and interoperability issues mentioned in their survey, and to potentially set up a meeting between W3C and WAVE participants to discuss in more detail.

Thanks,

Chris

Subject: WAVE Project liaison on Commercial DRM Testing

External: Think before clicking

Hello Media Working Group,

We received an incoming liaison letter from the CTA WAVE Project,
targeted at the Media Working Group, about the Encrypted Media
Extensions specification that group works on.

CTA WAVE is looking to extend the coverage of EME testing to include
content protected by commercial DRM systems such as Fairplay, PlayReady
and Widevine. CTA WAVE seeks input on people's experiences with the EME
API to help guide this work. The letter includes the results of a
recently completed survey that identifies imminent needs of the industry
for testing different commercial DRM features.

CTA WAVE is generally committed to extending the test suite for
commercial DRM tests but looking for partners to help support the
development financially. In addition to financial participation, they
are looking for a license server that can be used for commercial DRM
testing.

See attached files for details.

Testing individual commercial DRM systems is probably out of scope of
the EME test suite in Web Platform Tests [1] but, beyond this letter, it
may also be interesting to look back at the test suite and consider
additional tests that could help catch interoperability issues in
implementations.

François
W3C Staff contact for the Media Working Group.
