Description
Last Pixel Select. Selects method to choose last pixel for the scaler to use.
0: Use video source line size.
1: Use video window size.
The preferred setting is 0. This will avoid unnecessary horizontal mirroring.
Spare. Bit is R/W but has no function.
Video Source Lines. Represents the total number of video source lines. For example, a
720x480 video image would have VSL = 480.
Description
Reserved (Read Only). Reads back as 0.
Video Color-Key. The video color-key is a 24-bit RGB or YUV value.
• If VG_CK (VP Memory Offset 008h[20]) is set to 0, the video pixel is selected within
• If VG_CK (VP Memory Offset 008h[20]) is set to 1, the video pixel is selected within
The graphics or video data being compared can be masked prior to the compare via the
Video Color Mask register (VP Memory Offset 030h). The video color-key can be used to
allow irregular shaped overlays of graphics onto video, or video onto graphics, within a
scaled video window.
the target window if the corresponding graphics pixel matches the color-key. The
color-key is an RGB value.
the target window only if it (the video pixel) does not match the color-key. The color-
key is usually an RGB value. However, if both GV_SEL and CSC_VIDEO (VP Memory
Offset 098[13,10] are set to 0, the color-key is a YUV value (i.e., video is not converted
to RGB).
