Synchronization
- From: Digital Video Broadcasting (DVB); Multimedia Home Platform (MHP), Specification 1.1 (ETSI 2000).
Notes:
MHP provides "triggers": small messages with a time code and action sent in a broadcast, which can start a particular video, audio or action. The synchronization features are similar to SMIL and it is not clear why the SMIL module of XHTML was not used.
