CARRIER-BASED ACTIVE TEXT ENHANCEMENT |
摘要 |
Auxiliary or enhanced features associated with broadcast television programs are activated using carrier-based active text enhancement (CATE) signals embedded within timed text (TT) associated with the broadcast program. The active text enhancements can be interpreted by the viewer's set top box (STB) or other receiver to activate software applications, video clips, imagery, uniform resource locators (URLs), interactive interface features or the like on either or both of primary or secondary displays. Timed text enhancements can flexibly reference different types of content to provide richer and more powerful viewer experiences for the viewer. |
