7.2.3
The Mixer/Blender block of the Video Processor module
performs all the necessary functions to properly mix/blend
the video data and the graphics data. These functions
include Color Space Conversion (CSC), optional Gamma
correction, color/chroma key, and the mixing/blending
logic. See Figure 7-10 for block diagram of the Mixer/
Blender block.
Video/Graphics mixing/blending must be performed in the
RGB format. The YUV to RGB CSC (Section 7.2.3.1 on
page 331) must be used on the video data if it is in YUV for-
mat. If Gamma Correction (see Section 7.2.3.2) on the
video data is desired, it must be done in the color space of
the input video data, which can be either YUV or RGB. If
Gamma Correction on the graphics data is desired, it must
be done in the color space of the input graphics data,
which is RGB.

The video data can be in progressive or interlaced format,
while the graphics data is always in the progressive format.
The Mixer/Blender can mix/blend either format of video
data with graphics data. F4BAR0+Memory Offset 4Ch[9]
programs the mix/blend format. Considering the color
space and the data format, the Mixer/Blender supports five
types of mixing/blending. Some of the mixing/blending
types have additional programming considerations to
enable them to work optimally. The valid mixing/blending
configurations are listed in see Table 7-1 on page 331
along with any additional programming requirements.
