KAM-DEC-4ADC-MUX Links and Web Pages
Frame Sync Web Page
Use the Frame Sync web page ( Figure 26 on page 46 and Figure 27 on
page 46 ) to:
Adjust horizontal and vertical timing, and
Freeze the current output or, if using a 2000GEN reference signal, select an
automatic freeze mode for output when the signal is lost.
Timing Adjustment
Table 5 shows the ranges of timing adjustment for 525 and 625 signal for-
mats.
Freeze Mode Selection
The Freeze mode controls available depend on the output timing reference
selected on the
Video Input Select Web Page on page 40 .
Frame Sync
mode (using the 2000GEN
Internal Frame Reference
output timing
reference) provides the manual activation selections plus
AutoBlack
and
AutoFreeze
modes to be used when the video signal is lost ( Figure 26 on
page 46 ). AutoBlack outputs a black signal while AutoFreeze outputs the
last complete video field.
You may also choose
Disabled Output
, which will disable the SDI output com-
pletely (no signal of any kind) when the signal is lost.
When set to Frame Delay mode (using the
Video In
output timing reference),
Freeze Mode allows you to manually freeze the output using Field 1 , Field 2 ,
one
Frame
, or
Disabled Output
( Figure 27 on page 46 ). A field freeze provides
less resolution and no motion artifacts in the output. In Frame mode, the
resolution is higher since both fields are present, but the presentation of
two fields can cause motion artifacts.
