HDCP Pro 2.2 could lead to black screens14 June 2016
Failing to observe the requirements of HDCP Pro 2.2 content protection could lead to displays going black across entire campuses, delegates at the InfoComm Future Trends seminar were warned last week.
Bill Nattress, director of channel strategy at Biamp Systems, said that the new standard acknowledges that the pro AV presentation community has “justifiable and legal reasons to distribute content and materials to multiple displays simultaneously”. To this end, the standard removes the limitations on the number of HDCP keys that can be distributed within a system. But, he added, there’s a catch. Systems must be periodically updated with the DCP’s ‘whitelist’ of approved use cases and ‘blacklist’ of unique devices that are barred from displaying HDCP-protected content – perhaps because they have been compromised.
For systems without a constant internet connection this means that “once a quarter, the licensed integrator must come on site and upload the new blacklist to the facility. If that does not occur, [DCP] are threatening that the entire facility could go black” – potentially an entire campus of AV presentation systems, he said.
