WAVE Project liaison on Commercial DRM Testing

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.
