           Within the Caption Screen, CEA-708 defines "Caption Windows" through which the caption text is rendered. For WebVTT we map CEA-708 "Caption Windows" to <a href="http://www.w3.org/community/texttracks/wiki/MultiCueBox">WebVTT Regions</a>. In CEA-708 there are at most 8 Caption Windows - in WebVTT we can define an unlimited number of regions.
