Presenters give a shout out to this forum and its contributors. At around the 50 minute mark the presenters go into what DRM is, and why MQA is a good example of it. They also detail the public/private key aspects of MQA better than I have seen before.
All in all a good presentation, the errors being mostly of omission, but with 60 minutes this is expected.
