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.
