Description
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.
