Video Processor Module

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 7-2along with any additional programming requirements.
