This version of the software adds “GangGain” and ‘GangOffset” checkboxes. When one or both of
these boxes are checked, changing the gain (or offset) of one color will simultaneously change the
gain (or offset) of the other 2 colors.
There is also a “YPbPr to RGB CSC…” button. This button displays the status of a YPbPr to RGB
color space converter in the evaluation board’s FPGA. Clicking on the button toggles the state.
There is more information about the color space converter in the next section.
Video Input Configuration
The ISL98001 evaluation platform does not automatically detect the video mode of the incoming
video signal. To obtain the correct image on the DVI monitor, the software needs to be told the format
of the incoming video signal. This is done using the Video Mode box, which is opened by selecting
“Select Input Video Mode” from the options menu.
Using the drop down menu, select the resolution and refresh rate that matches the resolution and
refresh rate of the video signal to be digitized. The input connector can also be selected at this time.
The ISL98001 evaluation board has a YPbPr to RGB color space converter (CSC) inside the FPGA.
The CSC allows YPbPr/component video signals to be displayed on TVs that expect RGB format. If
you are using such a TV, checking the “Auto Enable YPbPr to RGB Color Space Converter for Comp.
Inputs” will automatically turn on the CSC when using a component or composite input.
