4.1 Synchronizing Playlist Displays Between Zones
You can synchronize the display between playlists in useful and sophisticated ways using rendezvous points and Advance
To commands.
Examples include:
Displaying video or images in one zone and related text captions in another zone (for a method to achieve this, see

Automatic Captioning

Displaying a selection of videos or images in response to ad hoc user input (for a method to achieve this, see
Video-on-Demand Using a Sub-Playlist
You can achieve further complex and powerful results with other of the rendezvous point and Advance To command
mechanisms:
An Advance To command executed in any currently playing playlist (including in the same playlist).
An Advance To command delivered over the iCOMPEL player's Ethernet port in the form of an XML message posted to
the HTML TCP port.
An Advance To command in a schedule entry or in an ad hoc page.
A change in binary input lines on the RS-232 port initiating an Advance To command.
An event on an attached touch-sensitive screen initiating an Advance To command.
4.1.1 Automatic Captioning
To implement synchronization between zones, you need to designate one playlist as the Master Playlist and one or more
other playlists as Slave Playlists. You add rendezvous points to each slave playlist and the identically named Advance
To command in the master playlist. When the master playlist reaches the Advance To command, the iCOMPEL forces
the slave playlists to start playing the first item after the rendezvous point.
To have the iCOMPEL perform automatic captioning, you have to use files with corresponding file names. For example, to
display captioning for a video file called Marketing_Highlights_01.mpg, you would need to create a file called
Marketing_Highlights_01.txt containing the text captions.
