Video Processor Module
The Video Processor module contains a high performance
video back-end accelerator, a video/graphics Mixer/
Blender, a Video Input Port (VIP), a Video Output Port
(VOP), and a TV encoder supporting three output choices:
TV, CRT, or TFT. The back-end accelerator functions
include horizontal and vertical scaling and filtering of the
video stream. The Mixer/Blender function includes color
space conversion, gamma correction, and mixing or alpha
blending the video and graphics streams. The high perfor-
mance TV encoder with horizontal scaling and flicker filter
provides all the necessary data formatting and timing to
create a quality TV output.
