Testing of time-based information

Dear Test People,

a few of us have been looking through the requirements and one thing isn't entirely clear:

"""
The test runner must support testing of time based information
The requirement is needed for SVG animation, HTML video for instance.
"""
  -- http://www.w3.org/wiki/Testing/Requirements#The_test_runner_must_support_testing_of_time_based_information

I'm not sure that I know how to do this properly without involving a high-speed camera or at least the ability to produce screenshots. By which I mean: I've seen tests written to check time based information and they've mostly involved writing the tests in a special way, e.g. having an animated gif and the animation run in parallel (which is problematic in itself) or having the animation pause at certain times to check that it matches certain markers (which has other interesting problems). I don't know how we can make this generic without adding the aforementioned things that are out of reach of the test runner.

Can whoever came up with this requirement clarify what they had in mind so that I can figure out if this is implementable?

Thanks!
