ABSTRACT:
A video processor integrates the processing of video and graphics data by restructuring the discrete blocks of luminance and chrominance component data associated with video image data (Y,U,V) into composite pixel values (YUYV), and performing the subsequent processing, in particular motion compensation, upon this composite data form. The discrete blocks of video image data are queue and processed in parallel to form a composite pixel value associated with each pixel within the image areas represented by the discrete blocks. By forming composite pixel values for reference data and error term data, common processing elements can be optimized and used for both video and graphics image processing. For example, the trilinear interpolator commonly used for 3-D graphics filtering and texturing can be used to form predicted macroblocks for motion compensation, and the specular adder used for graphics lighting effects can be used to process the motion compensation error terms.
