Abstract:
A system and method for compressing video graphics data are provided. The system and method include generating in a graphics pipeline, from video graphics data modeling objects, vertex data corresponding to the objects, rendering the video graphics data to produce a current frame of pixel data and a reference frame of pixel data, and, based upon the vertex data, defining a search area within the reference frame for calculating a motion vector for a block of pixel data within the current frame. The current frame then is compressed using the motion vector. The use of vertex data from the graphics pipeline to define the search area substantially reduces the amount of searching necessary to generate motion vectors and perform data compression.
