Video Processor Module
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 can be performed in either
the YUV or RGB format. The YUV to RGB CSC (see Sec-

blending is desired and the RGB to YUV CSC is used on
the graphics data when YUV blending is desired. 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.
