Frame Sync Web Page
Use the Frame Sync web page to:
• Adjust horizontal and vertical timing, and
• Freeze the current output or, if using a 2000GEN reference signal, select
an automatic freeze or disable mode for output when the signal is lost.
Timing Adjustment
Table 12 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 69 .
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 43 on
page 75 ). 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 44 on page 75 ). 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.
