I don't know much about this sort of thing either, but the paragraph above 
makes me think of SMIL:

W3C's Synchronized Multimedia Activity has focused on the design of a new 
language for choreographing multimedia presentations where audio, video, 
text and graphics are combined in real-time. The language, the Synchronized 
Multimedia Integration Language (SMIL) is written as an XML application and 
is currently a W3C Recommendation. Simply put, it enables authors to specify 
what should be presented when, enabling them to control the precise time 
that a sentence is spoken and make it coincide with the display of a given 
image appearing on the screen.
