In Part 1
of the HDCP 2.2 webinar series, we explored the origins and evolution of HDCP, why we have it, and how the different versions compare. We’ve had some great feedback that the webinar answered many long prevailing questions, but we still have a lot of ground to cover! Did you know?
- With HDCP 2.2, the main encryption key changes about every five seconds.
- HDCP 2.2 locality check requires a response in under seven milliseconds for most adaptations, but 20 milliseconds for HDMI.
- The leading cause of HDCP errors are protocol timeouts, most commonly seen as long start-ups.
For Part 2: How HDCP Works
, it’s time to roll up our sleeves and get under the hood of HDCP. So in case you’re wondering, yes it’s even more technical. We’ll have a look at how the HDCP authentication protocols work, what all those "keys" are for, and some of the critical timings and abort possibilities which can cause undiagnosed problems on the job.
Part 1 is recommended viewing before attending this webinar, so if you missed it live, you can catch up on it now
. In July, we’ll present the third and final webinar in the series, which brings together the implications of HDCP 2.2, the enhanced features of HDMI 2.0, and their combined impact on successful AV system design.
I look forward to joining you for Part 2 on June 16, 2016 at 6:00 p.m. ET
