问题 In W3C TTML dfxp standard, a div element can contain begin , end and duration attributes. How to interpret the value of these timing attributes? Example: <div begin="00:00:22.0 end ="00:00:30.0"> <p begin="0s" end="1s">Hi,</p> <p begin="3s" end="5s">Hello</p> <p begin="5s" end="10s">there?</p> </div> When to present p elements? Any pointers to TTML spec/implementation would be helpful. 回答1: The latest TTML spec is at http://www.w3.org/TR/ttml1/ Many of the timing semantics come from SMIL 2.1.
