+          CEA-708 pop-on captions rely on a Caption Window to be defined and mapped to a WebVTT Region as described in the section on "Positioning in CEA-708". Further attributes of the Region are described in section "Caption Text and Region Settings in CEA-708". Pop-on captions are the typical way in which cues in Regions are displayed. Regions are not displayed when there is no text in them.
