Synchronized Scripting 

More often than not, our Show Controllers interface to multiple digital video 
players at one time.  When these players are commanded to play 
unsynchronized, there is little concern with timing.  Here is an example of two 
unsynchronized video players.

Synchronized Video Playback 

When Digital Video Machines are asked to output video and audio together, it is 
important that they are commanded to play simultaneously in order to achieve 
frame-to-frame synchronization of audio and video. 

The following sequence causes the second player to play after the first, which 
causes unsynchronized playback.  Even though the 

Play

 events happen on the 

same frame, the first 

Play

 event may take a frame or two for the Show 

Controller to send out the serial play message.  The DVM will begin playing, 
return an Acknowledge, and only then can the second Play event begin to occur, 
throwing the sync out the window.

The following sequences show the correct way to script this.  The serial 
messages will go out both ports simultaneously, and the players will begin 
playing in synchronization.
