Connecting a Reference Signal
All Avid DNG systems require a video reference signal from a black
burst generator or the house black reference signal (see
Figure 8-3). The reference signal connects to the Video Slave Driver
and Avid Media Processor, as well as any deck and V-LAN VLXi that
are part of the system. The Video Slave Driver then uses the slave
clock signal to synchronize the audio interface.
