6.12.3. Filter Settings

6.12.3.1. Scaler Filter Sharpness
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 to the output. The larger the value, the wider the corresponding filter bandwidth.
The H Filter Cutoff controls the horizontal filter bandwidth. It also has several unique filters that have
specific enhancement profiles.
Levels 5....64
Auto
Enhance HF 1 db
Enhance HF 2 dB
Mid Band Boost 1 dB
Mid Band Boost 2 dB
The V Filter Cutoff controls the Vertical filter bandwidth.
Levels 1....64
Auto

6.12.4. AFD Stamp Settings

These controls enable the user to specify the type of outgoing AFD code. Depending on the type of AFD
being used there will be a variety of selected AFD stamp codes. The AFD Stamp control is enabled only
when the AFD Stamp Source is set to User AFD Stamp. Use the AFD Stamp drop down menu to select
the appropriate out-bound AFD code. There are 20 SMPTE2016-1 AFD codes to choose from. As each
AFD code is selected, a pictorial representation of what that AFD code means is shown in the right hand
side of the screen.
7812UDXD Series 3G/HD Up/Down/Cross Converter with Simultaneous Dual Format Outputs and AES I/O
Selects the horizontal filter bandwidth such that each value 5 through 64
th
corresponds to 1/64 the bandwidth of the input signal.
The optimal horizontal filter is automatically selected to match the scaling
and aspect ratio conversion process being performed.
High frequencies within the image are enhanced by 1 dB
High frequencies within the image are enhanced by 2 dB
Mid band frequencies within the image are enhanced by 1 dB
Mid band frequencies within the image are enhanced by 2 dB
