This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
This issue is raised on behalf of HbbTV - see http://www.hbbtv.org, an organisation specifying the use of web technologies in television receivers. HbbTV is in the process of adding the HTML5 video element to its specification. The current HbbTV specification uses the <object> element for presenting video in an HTML page. One of the steps in the description of automatic text track selection is the following; http://www.w3.org/TR/html5/embedded-content-0.html#honor-user-preferences-for-automatic-text-track-selection "3. If any of the text tracks in candidates have a text track mode set to showing, abort these steps.". As mentioned in issue #24860, TV receivers include a UI to enable the user to set and change preferences relating to subtitles/closed captions. The subtitle UI in a TV receiver almost always permits the end-user to disable as well as enable subtitles. The text from "honor user preferences" above can be interpreted as meaning that the "Honor user preferences for automatic text track selection for this element" process can never result in subtitles that were showing becoming hidden. We would appreciate your feedback on whether a mechanism in the user agent to permit the end-user to disable subtitles is compatible with the definition of "Honor user preferences". If such a mechanism is not compatible with "Honor user preferences", can this be changed?
*** This bug has been marked as a duplicate of bug 24860 ***
I'm confused why this is considered a duplicate of #24860. Although both #24860 and this issue relate to the "honor user preferences for automatic text track selection" process, #24860 is about when this process happens #24862 is about the inability of this process to disable subtitles currently being shown.

This is a duplicate because you are looking at the wrong part of the spec for the process that you are after and that other part has the ability to disable subtitles as part of it. Thus, they are not 2 different issues.
