Auto Freeze: This pulldown (ON/OFF) enables or disables the auto freeze function. In Auto Freeze mode, a
reference must be present to ensure a glitchless output when a freeze is activated. There are only two freeze
possibilities in Auto mode: freeze to last valid Field or freeze to black. When Auto Freeze mode is disabled,
the content of the active picture will reflect whatever garbage is present at the input but, if a reference is
present, the output synchronization will be maintained to avoid unlocking downstream equipment.
Activate Manual Freeze: Select this checkbox to immediately freeze the output according to the mode
selected in the Freeze Type pull-down.
Note: The manual freeze setting is saved in the non-volatile memory of the card. If the manual freeze is
activated and the power is cycled, the card will start in freeze mode at the next power-up and the output will
be invalid. Just turn off the manual freeze to restore the output.
In all cases, audio will be muted when there is an input error. See audio section for more information.
