1: Enable. The graphics window is assumed to be inside the video window. Outside the
YUV Color Space Conversion Enable. Enables YUV to YUV color space conversion on
the video YUV input. HDSD_VIDEO (bit 6) is used to determine which resolution the
source video is. The video will be converted to the opposite resolution.
If HDSD_VIDEO = 0: YUV
If HDSD_VIDEO = 1: YUV
High Definition/Standard Definition CSC on Video. Determines what the source video
resolution is for both YUV to RGB and YUV to YUV color space conversion algorithms.
0: Video source is in Standard Definition (Rec.ITU-R BT-601).
1: Video source is in High Definition (Rec.ITU-R BT-709).

Cursor Color Key Enable. This bit enables the cursor color key matching function.
0: Disable. Graphics data will never match the cursor color key.
1: Enable. Graphics data is compared to the cursor color key.
Cursor Color Register Offset. This field indicates a bit in the incoming graphics stream
that is used to indicate which of the two possible cursor color registers should be used for
color key matches for the bits in the graphics stream.
Cursor Color Key. Specifies the 24-bit RGB value of the cursor color key. The incoming
graphics stream is compared with this value. If a match is detected, the pixel is replaced
by a 24-bit value from one of the cursor color registers.
alpha window, graphics or video is displayed, depending on the result of color key
comparison.
alpha windows, video is displayed instead of graphics. Color key comparison is not
performed outside the alpha window.
