Test 1 (15.11)

iOS and Android

For conditions relating to resolution and frame rate, the safest way to assess this criterion is to search either the interface or the application's documentation for this information. It is also advisable to ask the application's publisher to provide these technical details. If the information cannot be found in the interface or its documentation, and the application publisher is unable to provide an answer on this technical characteristic, these conditions cannot be validated, the criterion will be considered non-compliant. For the last condition concerning the time lag between video and audio, the test can be established by simple observation:

1. Activate the application on two devices.
2. Establish a video call connection between the two devices.
3. Check that speech and video are synchronised (lip-sync, lip movement).
4. If this is the case, the test is validated.
