Frame Sync Web Page
Use the Frame Sync web pages ( Figure 23 on page 40 and Figure 24 on
page 40 ) 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 for 525 and 625 signal formats.
Freeze Mode Selection
The Freeze mode controls available depend on the output timing reference
selected on the
Video Input Select Web Page on page 35 .
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 23 on
page 40 ). AutoBlack outputs a black signal while AutoFreeze outputs the
last complete video field.
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 24 on page 40 ). 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.
