Initial Configuration Process Overview
Frame Sync Web Page
The HD or SD Frame Sync web page (applicable for modules with Frame
Sync capability, KAM-HD-FS or KAM-HDD-FS) provides adjustments for
horizontal and vertical output timing, a minimum delay mode, loss of
signal controls, and a delay wrap position graphic.
Note
For KAM-HDD and KAM-HDD-PA module timing capabilities, refer to
leon HD Timing Considerations on page 20
for
Frame Reference
and
Input
reference) provides horizontal and vertical
timing, a minimum delay mode, loss of signal controls, manual freeze con-
trols, and a delay wrap position graphic.
Note
The controls available on the Frame Sync page depend on the Output Timing
Source selected on the System Config web page.
Timing Adjustment
When the Frame Sync capability is present, horizontal and vertical timing
adjustments can be made on the output video as required relative to the
input video signal (output timing source =
Input
), or relative to the external
reference (output timing source =
Frame Reference
) with the following con-
trols:
•
H Timing (Pixels)
– the horizontal timing can be adjusted in pixels.
•
V Timing (Lines)
– the vertical timing can be adjusted in lines.
Note
On any HD input signal at any line rate, down converted SD and Composite
outputs will be within ± 1/2 SD pixel of the timing setting.
Minimum Delay Mode
A minimum delay can be enabled to bypass portions of the frame sync
memory to allow an absolute minimum amount of delay through the
module. To enable this mode, check the
Enabled
checkbox. Refer to the Elec-
trical Length in the
for notes on using this mode.
Loss of Signal Operation
When the output timing source is set to
Frame Reference
, set this control to
define the action of the output when the input signal is detected as lost. The
choices are to either
Pass
the video, do an
Auto Freeze
(on the last good video
frame), or take the output to a blue screen (
Auto Blue
).
This control will default to
Pass
(no
Auto Freeze
or
Auto Blue
) when the output
timing source is set to
Input
.
