Model 5152
Video Generator/Audio Embedder Module
SDIINPUT= selects which physical SDI
input on the module will be active. There
are two choices. BNC selects the coaxial
(BNC) SDI input to be active.
SFP selects
the optical SDI input to be active.
FORMAT= selects the SDI Output Image
Format/Rate Mode. There are two choices.
AUTO selects the Auto Select (Follows
Input) mode. LOCKED selects the Locked
(Does Not Follow Input) mode.
IMGDELAY= selects the interval for the
delay before the stored image is output.
The range is 0 to 7 seconds. A setting of
0 selects no delay. During the delay period
the Model 5152 will output a video image
with a solid-gray color.
MOTION= selects the status of the Mov-
ing Image Overlay function. There are two
choices. OFF disables the Moving Image
Overlay function.
ON enables the Moving
Image Overlay function.
SDIMODE= selects the status of the SDI
Mode function. There are two choices.
NORMAL selects that a valid SDI sig-
nal connected to the selected SDI input
will pass through to the module’s SDI
output(s). REFONLY selects that the SDI
input will serve only as a timing reference
signal. The internally-generated image will
always be sent to the SDI output(s).
EMBED= configures how audio signals
connected to the Model 5152’s digital
audio inputs are to be embedded into the
SDI output signal. The first digit represents
what is to happen to the audio associ-
ated with digital audio inputs 1 and 2. The
second digit represents what is to happen
to the audio associated with digital audio
inputs 3 and 4. The digit
N indicates that
the digital audio inputs are not to be
embedded. The numbers 1, 2, 3, and 4
represent the SDI group that the digital
audio inputs are to be embedded into.
Figure 9 shows EMBED=34 which indi-
cates that digital audio inputs 1 and 2 are
to be embedded into SDI group 3 and
digital audio inputs 3 and 4 are to be em-
bedded into SDI group 4. Another example
would be
EMBED=2N which would specify
that digital audio inputs 1 and 2 are to be
embedded into SDI group 2 while digital
audio inputs 3 and 4 are not to be embed-
ded (inactive).
A special configuration selection is
EMBED=NN. This configures the Model
5152 to not embed any audio signals. In
this situation any embedded audio as-
sociated with the connected SDI input will
pass through the module. While this con-
figuration will typically not be used it can
prove to be useful in certain situations. For
example, it can be used during trouble-
shooting, disabling the Model 5152’s em-
bedding function and allowing an SDI input
to pass through the module completely
unchanged. Test signals can be confirmed
as passing through the module correctly
and terminating on a downstream piece of
equipment. Turning off embedding can also
be useful when, in a special application, all
the audio groups associated with an SDI
input need to remain embedded and pass
through to the Model 5152’s SDI output.
