3.6.4. Setting Up the AES Audio Reference Reference
(SoftSwitch
and Embedded SoftSwitch
equipped routers only)
REFERENCE
This menu is used to select the type of audio reference being used for the
SoftSwitch
equipped routers. These routers can accept a DARS reference
signal to ensure the Z bit alignment on the AES outputs. If
video
is selected,
the Z bit alignment of the AES outputs is random. If
DARS
is selected and the
DARS reference is absent, the router will revert to
video
lock. On the SS
routers, for the SoftSwitch
technology to function correctly, the audio
sources must be synchronous with the chosen
Audio Reference.
See section
2.1.6 for information on connecting a DARS reference.
In order for the Embedded SoftSwitch
technology to function correctly on the
ESS routers, the AES sources must be synchronous with the
Video reference
and the A
udio Reference
for the router should be set to
video
. (If you are
using a DARS reference with ESS, then the DARS reference must be locked
to the video reference.) If Embedded SoftSwitch
functionality is not required
(e.g. Dolby E in the embedded stream) then the AE SoftSwitch can be
disabled and the router can function the same as a SoftSwitch
equipped
router.

CONFIGURING THE VIDEO AND AUDIO TRANSITIONS
3.7.1. Configuring the Switch Line
TRANSITION
On the Standard Definition Routers this menu allows the user to select which
line of the video reference the switching will occur on. Valid values are 1 to
64, with the default switch line set to 10.
Switch Line
Switch line = 10
TRANSITION
On HD routers this menu allows the user to select which line of the video
reference the switching will occur on.
On routers that do not have SoftSwitch
, the switch line number will be the
line number of the video reference.
On SoftSwitch
equipped routers, when using a bi-level sync reference, the
switch line number will be the equivalent line number in HD, as shown in
Figure 3-3 and Figure 3-4. When using a tri-level sync reference, the switch
line number will be the line number of the HD video reference. Valid values
are 1 to 64, with the default switch line set to 7 as per SMPTE RP168-2002.
For proper timing operation the
Input Standard
setting on the
INPUT SETUP
menu must be set to match the input video format. (See section 3.8.1)
Switch Line
Switch line = 7
