For rendered content where user input is only possible within a finite time interval controlled by the user agent, allow configuration to provide a view where user interaction is time-independent.
Sufficient techniques
The user agent may satisfy this checkpoint by pausing processing automatically to allow for user input, and resuming processing on explicit user request. When using this technique, pause at the end of each time interval where user input is possible. In the paused state:
Alert the user that the rendered content has been paused (e.g., highlight the pause button in a multimedia player's control panel).
Highlight which enabled elements are time-sensitive.
Allow the user to interact with the enabled elements.
Allow the user to resume on explicit user request (e.g., by pressing the play button in a multimedia player's control panel; see also checkpoint 4.5).
The user agent may satisfy this checkpoint by generating a time-independent (or, "static") view, based on the original content, that offers the user the same opportunities for interaction. The static view should reflect the structure and flow of the original time-sensitive presentation; orientation cues will help users understand the context for various interaction opportunities.
Normative inclusions and exclusions
When satisfying this checkpoint for a real-time presentation, the user agent may discard packets that continue to arrive after the construction of the time-independent view (e.g., when paused or after the construction of a static view).
This checkpoint does not apply when the user agent cannot recognize the time interval in the presentation format, or when the user agent cannot control the timing (e.g., because it is controlled by the server).
