stnishimura has just created a new issue for 
https://github.com/w3c/media-source:

== Needs mechanism to present texts and graphics accurately 
synchronized with video at low processing load. ==
Since the interval of timeupdate event depends on implementation, it 
is difficult to find a good balance of the accuracy and processing 
load through different implementations. A use of setInterval can 
control frequency and accuracy but requires additional processing load
 which causes significant impact on low power devices like TV. It is 
ideal if the event mechanism like cuePoint in Actionscript is 
available, but such methods are not yet defined.

This is one of the issues raised in the Web and TV IG meeting at TPAC 
2015 by Hybridcast group.
