Flash & Pattern Legaliser
Building on the success of our Harding Flash and Pattern Analyser's, Whitedot Scientific have now developed a new system to generate Ofcom compliance in real time. The Flash and Pattern Legaliser calculates exactly when and by how much the photosensitive guidelines have been exceeded and then uses a suite of algorithms to implement the minimum correction necessary to achieve compliance.
The Legaliser is NOW available! Please contact us to register your interest in this product, and we'll let you know when the release date is announced.
The Flash and Pattern Legaliser can be used for live video feeds where post production video editing is not an option. Alternatively, it can be used as a video editing aid for correcting some flash and pattern failures without constraining an editor’s flair and creativity for correcting major violations.
Real-Time Correction
The Flash and Pattern Legaliser corrects video for Ofcom compliance in real-time with a latency of less than 5 seconds. It is able to correct for luminance flashing, red flashing, extended flashing and spatial patterns in real time even when all occur simultaneously. The figure below shows a commercial which exceeds Ofcom flash guidelines in 5 places while the lower graph shows the real-time legalised video free of all flash and extended flash violations.
Now Take a Closer Look
The Flash and Pattern legaliser performs the absolute minimum changes to the video to achieve Ofcom compliance. A close-up of the legalised video analysis shows that flashing activity is frequently very close to the Ofcom limit while separate checks ensure that flash violations, once corrected, do not reappear as extended flash failures.
Legalised Video Analysis
A replay of the corrected video will, in most cases, contain no noticeable changes. Most flash and pattern violations are minor requiring negligible alteration for compliance. Major flash violations will still appear flashy after legalising and retain the same visual excitement of the original. All flash and patterned stimuli which go close to, but do not exceed, guideline limits are left completely unaltered.
The Flash and Pattern Legaliser represents a fast route to transmission compliance. By working with the Harding Flash and Pattern Analyser engines, it knows exactly when and by how much the guidelines have been exceeded. This enables the legaliser to perform the absolute minimum level of video correction necessary to achieve full compliance within a two pass process, in real time and with a latency of less than five seconds.
