ADC-8733A User Manual (Iss. 02B) Menus • 4–17
• If you cross over the maximum Horizontal Delay, the value returns to 0 (zero) and the
Vertical Delay value increments by 1.
• Crossing the minimum delay returns the Horizontal Delay value to 1715 (525-line
standard) or 1725 (625-line standard) and decrements the Vertical Delay value by 1.
• If at maximum Horizontal Delay and maximum Vertical Delay, incrementing the
Horizontal Delay value will cause the Vertical Delay value to wrap from maximum value
to the minimum value.
• If at minimum Horizontal Delay and minimum Vertical Delay, decreasing the Horizontal
Delay value will cause the Vertical Delay value to wrap from minimum value to the
maximum value.
3 - Horizontal Reset
This menu resets the Horizontal Delay to 0.
4 - Vertical Delay
Extra delay can be added to the output video in line increments. Vertical Delay can add up to a
maximum of 524 lines in the 525-line standard or 624 lines in the 625-line standard. This menu
uses ballistics. Note the following points when adjusting the Vertical Delay:
• If you cross over the maximum Vertical Delay, the value returns to 0 (zero).
• Crossing the minimum delay returns the Vertical Delay value to 524 (525-line standard),
or 624 (625-line standard).
5 - Vertical Reset
This menu resets the Vertical Delay value to 0 (zero).
6 - Minimum Delay
This menu resets both the Horizontal Delay and Vertical Delay values to 0 (zero). Note that this
resets the Horizontal and Vertical Delay values across all Timing Modes.
8 - Freeze Mode
The Freeze Mode function allows you to set what will be the output when a freeze occurs (as set
by the Forced Freeze menu). The output is be frozen (ADC-8733A-S only) if any of the
following conditions occur:
• The user freezes the output manually. Refer to the section, “9 - Forced Freeze”.
• There is a loss of input signal. Refer to the section, “A - Input Loss Mode”.
9 - Forced Freeze
The output can be manually frozen (ADC-8733A-S only) using the Forced Freeze menu. When
enabled, it will freeze Field 1 only, Field 2 only, or the entire frame as determined by the Freeze
Mode function. If Forced Freeze is set to ON, the output is frozen only if the Timing Mode is
set to Frame Sync.
A - Input Loss Mode
The Input Loss Mode function selects what type of video appears at the card’s outputs when the
input signal is lost or invalid.
Note — Before selecting the Black or Freeze options, first ensure that the Reference
is not set to the same value as the Input Timing.
