Parallel playlist (par)
The SMIL parallel playlist is a list of media objects that start playback simultaneously.
Illustration of using the parallel playlist for multi-zone effects are located in the section on Layout.
Children of the parallel playlist can be specified to start at a specific "wallclock" time defined by the player's real-time clock. See section on Wallclock for details.

The parallel schedule has two children: a sequential playlist containing 3 still images, and a single audio media object. The sequential playlist and the audio object start simultaneously, achieving the effect of a slide show of 3 photos while music plays in the background.
