Description
Alpha Window 1 Priority. Indicates the priority of alpha window 1. A higher number indi-
cates a higher priority. Priority is used to determine display order for overlapping alpha
windows.
This field is reset by hardware to 00.
Enable Alpha on DRGB[31:24]. The source of the alpha value is the upper 8 bits [31:24]
of the graphics input bus. When this bit is set, the upper 8 bits of the graphics input bus is
passed through to the upper 8 bits [31:24] of the DRGB output bus. If bit 14 is also set,
the actual video blended alpha value replaces the graphics alpha value when inside an
alpha window.
00: DRGB[31:24] are not driven.
01: DRGB[31:24] are not driven.
10: DRGB[31:24] contain contents of graphics input bus [31:24].
11: DRGB[31:24] contain contents of graphics input bus [31:24] when NOT inside any
Enable Video Alpha value onto DRGB[31:24]. When inside an alpha window, drive the
video alpha value (graphics per-pixel alpha value multiplied by the multiplier) onto bits
[31:24] of the DRGB output bus.
00: DRGB[31:24] are not driven.
01: DRGB[31:24] are not driven.
10: DRGB[31:24] contain contents of graphics input bus [31:24].
11: DRGB[31:24] contain contents of graphics input bus [31:24] when NOT inside any
Graphics Video Select. Selects input video format.
0: YUV format.
1: RGB format.
If this bit is set to 1, bit EN_420 (VP Memory Offset 000h[28]) must be set to 0.
Color Space Converter for VOP. Determines whether or not the output from the blender
is passed through the Color Space Converter (CSC) before entering the VOP.
0: Disable. The output of the blender is sent “as is” to the mixer/blender.
1: Enable. The output of the blender is passed through the CSC (for RGB to YUV conver-
Color Space Converter for Graphics. Determines whether or not the graphics stream
is passed through the Color Space Converter (CSC).
0: Disable. The graphics stream is sent “as is” to the mixer/blender.
1: Enable. The graphics stream is passed through the CSC (for RGB to YUV conver-
Color Space Converter for Video. Determines whether or not the video stream from the
video module is passed through the Color Space Converter (CSC).
0: Disable. The video stream is sent “as is” to the video mixer/blender.
1: Enable. The video stream is passed through the CSC (for YUV to RGB conversion).
High Definition/Standard Definition CSC. Determines which algorithm to use for
graphics color space conversion from RGB to YUV.
0: Standard Definition.
1: High Definition.
