Revision 1.2
None
General noise temporal will not be enabled.
Low
A Low level of temporal noise reduction will be applied.
Medium
A Medium level of temporal noise reduction will be applied.
High
A High level of temporal noise reduction will be applied.
NOTE:
Setting the value higher than needed to remove the noise present, will over soften
areas of low amplitude, fine details.
NOTE:
Setting the value too low may cause the circuitry to leave random noise that it could
remove. However, removal of low-level details will be minimized.

SCALER
The Scaler control menu is used to configure the cut-off frequencies of the polyphase filters.

Scaler Controls
There are two controls that adjust the horizontal and vertical filters for the scaler. Effectively, these
controls manage the cut-off frequency for the Horizontal and Vertical filters.
The smaller the value, the narrower the corresponding filter bandwidth and the less aliasing passed
through the output. The larger the value is, the wider the corresponding filter bandwidth will be.
Horizontal Filter Cutoff Frequency:
It controls the Horizontal filter bandwidth. It also has several unique
filters that have specific enhancement profiles.
Auto
The optimal horizontal filter is automatically selected to match the scaling and aspect
ratio conversion process being performed.
Enhance HF 1 db
High frequencies within the image are enhanced by 1 dB.
Enhance HF 2 dB
High frequencies within the image are enhanced by 2 dB.
Mid Band Boost 1 dB
Mid band frequencies within the image are enhanced by 1 dB.
Mid Band Boost 2 dB
Mid band frequencies within the image are enhanced by 2 dB.
Levels 5….64
Selects the horizontal filter bandwidth such that each value 5 thru 64 corresponds to
1/64
th
the bandwidth of the input signal.
