Video Processor Module 32579B

Video Processor Module7

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.
