Digital Video Option (/D)
The S/PDIF output is
a standard IEC-958
signal containing
either Stereo (2-
channel) or Digital
AC3 (5.1 Channel)
audio.
The sync output is
NOT a passive
connection to the sync
input. It actually
generates a
Composite sync
signal.
A Digital Video Machine equipped with this option provides SMPTE259M digital video
on a BNC connector.
In addition, this option provides the DVM with the ability to synchronize to an external
video sync source using the sync input. The sync output can be used to feed video
sync into other devices (such as other DVM’s). For more information on the sync
features of the DVM, see the Synchronization section in this manual.
This option also provides a digital audio RCA jack for outputting S/PDIF Stereo Audio
or Dolby Digital 5.1 Surround Sound.
