KAM-DEC-2AES Links and Web Pages
Frame Sync Web Page
Use the Frame Sync web page ( Figure 23 on page 41 and Figure 24 on
page 41 ) 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 36 .
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 ,
or one Frame ( Figure 23 on page 41 ). 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.
Frame Sync mode (using the 2000GEN Internal Frame Reference as the output
timing reference) provides the manual activation selections plus AutoBlack
and AutoFreeze modes to be used when the video signal is lost ( Figure 24 on
page 41 ). AutoBlack outputs a black signal while AutoFreeze outputs the
last complete video field.
