Antialiasing system and method

Abstract

A system and method for improved antialiasing in video processing is described herein. Embodiments include multiple video processors (VPUs) in a system. Each VPU performs some combination of pixel sampling and pixel center sampling (also referred to as multisampling and supersampling). Each VPU performs sampling on the same pixels or pixel centers, but each VPU creates samples positioned differently from the other VPUs corresponding samples. The VPUs each output frame data that has been multisampled and/or supersampled into a compositor that composites the frame data to produce an antialiased rendered frame. The antialiased rendered frame has an effectively doubled antialiasing factor.

1 . A video processing apparatus, comprising:
 a plurality of video processing units (VPUs), wherein each VPU processes data corresponding to one or more video frames, including sampling pixels of the one or more frames to generate a plurality of samples such that each VPU generates different samples; and   an interlink module that receives the plurality of samples from each VPU and combines the samples in an output video frame.
