8981FS Instruction Manual 11

Conﬁguration

setting does not result in at least this much signal delay from video input

to output, the module will delay the signal up to one frame. The output

timing controls can adjust the serial digital output timing:

■ ± 1 ﬁeld, in 1 H-line steps and

■ Over 1 line in 37 ns steps.

Total timing range is slightly greater than one full frame.

If the Restore Defaults conﬁguration is recalled, the serial digital output

timing will revert to providing a video output exactly in time with the ref-

erence input.

If the Reference input signal is lost, the module will revert to the ﬁxed delay

operating mode. The video output signal will continue to be present. The

audio delay control output will continue to function.

Fixed Delay Mode

The Frame Sync function can be turned off to operate the module as a ﬁxed

video signal delay of up to one frame. In this mode no reference input is

required. Delay is adjustable:

■ From two lines to one frame in one line steps and

■ In 37 ns steps over one horizontal line.

Input Signal Loss

Upon input signal loss the, the user can select between three output signal

options:

■ Freeze of the last good ﬁeld (Auto-freeze)

■ Force the output to black, or

■ Pass the input signal as is.

To select a freeze of the last good ﬁeld the Auto-freeze mode should be

ENABLED and the Output With No Input mode should be set to PASS. (See

Table 3 on page 15, Function Switch positions 7 and 8, Bank 1)

To select a black output signal the Output With No Input mode should be

set to BLACK. This function will override video freezes if the input signal

is lost. For automatic freezes to cover input signal Hot Switches, ENABLE

the Auto-freeze mode.

To pass the input signal as is without a last good ﬁeld freeze or forced black

Auto-freeze mode should be set to DISABLE and Output With No Input

should be set to PASS. In this mode automatic freezes are disabled and non-

synchronous input signal hot switches will appear in the output signal.
