4.1 Deaf users: Video resolution and frame rates

Scenario: A deaf user watching a signed broadcast needs a high-quality frame rate to maintain legibility and clarity in order to understand what is being signed.

As a point of interest, research that RNID performed found that BSL users watching signed content focused on the lips and took in the physical hand gestures and body movements through peripheral vision. There was talk at the time of adaptive video compression algorithms that compressed facial features less. I'm not aware that anything came out of that though and it feels rather ambitious. I'm not sure how this info impacts RAUR but it may be useful back-of-mind stuff.

This looks editorial to me, but also chimes with some of @JaninaSajka finding on the mechanics of comprehension that are enabled by being able to lip read. @JWJPaton
