Photosensitive Epilepsy (PSE) Testing: Warner Bros. Discovery’s Standards 

Policy applicable through June 5, 2024:

Photosensitive Epilepsy is a condition that causes people to have seizures in response to some types of visual patterns and images.  The condition mostly affects children and about one child in every 4000 suffers from it.   Media images can trigger those seizures and major incidents stemming from broadcasts in Japan and the UK sparked PSE regulations in those countries.   Discovery uses a two-test process to evaluate video for PSE triggers.  If the content fails an initial test, Discovery will run a second test using different testing software to rule out test error or bias.  If the content fails the second test, Discovery will return it to the production partner for correction or replacement.    Discovery strongly encourages producers to obtain certification in advance of delivering program masters.

If a program or element does fail the PSE tests conducted by Discovery, production partners can provide their own passing PSE certificate by uploading to the Producer’s Portal under “Photosensitive Epilepsy Certificate”.  Discovery will accept test certificates from any test system approved by the Digital Production Partnership (DPP).  The DPP maintains a current list on their specifications website: https://www.thedpp.com/delivery/uk#  (Look under “Supplements” and you’ll find a document for “PSE Devices”). A passing PSE certificate (from any vendor approved by the DPP) supersedes any PSE failures indicated on the Tech Evaluation report by Discovery

Producer Updates as of February 21, 2024:

Our multimedia visual products require approved flash pattern analysis to check for photosensitivity if they may be a problem for photosensitive viewers. WBD continues to use industry-standard software to test all incoming content.      

POLICY CHANGE:   

Program masters delivered to Warner Bros. Discovery via producers.discovery.com on and after February 22, 2024 will be evaluated with a different flash and pattern analysis software than content delivered prior to this date. We understand you may have questions if your program’s technical evaluation report contains different feedback after this date. To accommodate active production delivery timelines, WBD will enter a policy adjustment period described here, until June 2024. 

TIMELINE:  

POLICY STARTING ON FEBRUARY 22, 2024: If content falls outside the test parameters, it may be rejected. The operations team will work with you to determine a path forward based on legal requirements, including the current policy of allowing certificates from compliant flash and pattern analyzers. You may see different information noted in your technical evaluation report from our flash and pattern analyzer. 

POLICY STARTING ON JUNE 5, 2024: At the end of the policy adjustment period in June, content that fails the PSE testing within WBD’s automated supply chain will be rejected based on those standards only. The acceptance process comes to a halt until the content passes this evaluation.     

Warner Bros. Discovery strongly recommends that providers use a Harding Flash and Pattern Analyzer on all content before delivery to ensure it meets those standards.    

As always, the deliverables and operations teams at WBD are available to you and your network contacts to answer any questions regarding any faults within your master technical evaluation reports.     

Thank you for your cooperation in this matter.
