Input Presets
The DSC HD-HD 4K Plus A Series scalers have 128 memory slots in which you can save
input presets. These presets allow a matrix switcher with multiple types of video inputs
(such as an XTP) to be placed upstream from the DSC to expand the number of video
sources. Input presets can be saved and recalled only through SIS commands (see the
Input Presets commands
on page 57).
•
When you recall an input preset, it fills the output raster based on the sizing and
positioning that it had at the time it was saved.
• Input presets can be saved based on one input rate and recalled to a different rate.
This enables presets to be used as aspect ratio or other quick-sizing shortcuts.
Values for the following settings are saved in input presets:
• Contrast • Active lines (V Active)
• Brightness • Horizontal image position
• Detail • Vertical image position
• Film detect • Horizontal image size (width)
• Audio gain and attenuation • Vertical image size (height)
• Active pixels (H Active) • Preset name
Saving a preset when using a matrix switcher
When using the DSC with a matrix switcher, do the following to save a preset:
1. Switch each input of the matrix to the DSC.
2. Configure each input: size, position, detail, brightness, and contrast. The remaining
settings (active pixels and lines) are not user-configurable, but are stored automatically
as part of the preset.
3. Save the settings to a preset for recall by the control system when that matrix input is
routed to the HDMI input.
