4.6 AFV Memory
Selecting this parameter and then pressing the up-arrow Adjust button saves the
current audio settings to source-memory for the currently selected video input.
5.1 Upconvert Mode
This parameter selects the type of upconversion performed on the incoming selected
SD source input.
4.5 Audio Follow Video Description of Choices
Parameter Adjustments:
OFF (Default)
ON
Normal operation. Audio settings must be made separately from any video settings;
they are not associated automatically.
The FS1 remembers the saved audio settings associated with the currently
selected input. Whenever an input is selected, the corresponding audio settings will
be recalled.
This allows you to set up specific audio settings for the different video inputs (i.e.,
perhaps the SDI 1 has a specific embedded audio channel mapping while the
component video input might always use AES audio input).
