4.17 For each pre-recorded time-based media, is the presentation of captions controllable by the user (excluding special cases)?
Official methodology to test criterion 4.17
Test 1 (4.17.1)
- Locate pre-recorded time-based media with captions.
- Define one or more caption presentation parameters from the customisation options provided by the operating system, for example: caption size, colour, border style, background colour, background opacity, etc. (Note: the standard does not give a precise list of parameters that must be defined, so the ability to modify a single caption characteristic is sufficient to make the criterion compliant).
- Check that the defined parameters are applied to the captions.
- If not, check the page to see if there is a function that allows you to change the presentation parameters of the captions (on the page or directly from the media player).
- Check that the defined parameters are applied to the captions.
- If this is the case, the test is validated.
