Automated File QC System Update For Photosensitive Epilepsy (PSE)

 Automated File QC System Update For Photosensitive Epilepsy (PSE)

Ofcom, the United Kingdom’s communications regulator, has announced an update to ITU-R BT.1702-0 which is now available in the form of ITU-T 1702-1. From January 1st, 2019, all TV programs must be tested using Photosensitive Epilepsy Algorithms to ensure that they comply with the revisions to the ITU Recommendation.

A complaint to Ofcom showed there were inconsistencies in the interpretation of the Broadcasting Code Harm and Offence section that details the requirements for PSE testing. The circumstances of the sequence that caused the complaint were very unusual and are very unlikely to occur naturally (the sequence was an edited effect). In this update, ITU has clarified the definition of a sequence of potentially harmful flashes.

Need For Photosensitive Epilepsy Test?

Photosensitive Epilepsy (PSE) is triggered by visual stimuli that overload the brain temporarily and cause a seizure. The triggers are commonly flashes or repeating changes between dark and light (such as stroboscopic effects or flash photography), some geometric patterns, and certain colors such as deeply saturated red. PSE affects around one in four thousand people, with the age group of seven to twenty years old being five times more likely to be susceptible than the rest.

PSE testing is mandatory in the UK and Japan. All content providers and broadcasters need to check for PSE compliance before the content is made available to consumers. Producer of the program, as well as the Broadcaster, may be liable for any action taken by Ofcom or a member of the public, for a breach of the Photosensitive Epilepsy requirements.

PSE testing is also used worldwide by content providers who create/repurpose content for these countries. This testing is growing in use in the US as well, particularly as more of the US-produced content is distributed internationally.

Automated File QC system for PSE Testing

Photosensitive Epilepsy testing can be performed along with other content checks using an Automated QC system. Considering the penalties involved with a violation of PSE guidelines, it is of paramount importance that a certified, reliable implementation is used for PSE testing. Some of the proprietary implementations available in the market are reported to be inaccurate. Using those implementations exposes content owners and broadcasters to potential penalties.

Venera’s Automated QC systems – Pulsar (for QC of on-premise content) and Quasar (for QC of cloud-based content) – use the Photosensitive Epilepsy implementation from Cambridge Research Systems, which is the de facto standard for Photosensitive Epilepsy testing, producing Cambridge-approved certifications. Both systems are already compliant with updated Ofcom guidelines and as a result, Pulsar/Quasar users are assured that if their content passes the QC inspection, they meet the latest Photosensitive Epilepsy standards.
