Patent ID: 8264493

Claim:
A system for synthesizing a compressed video bit stream from an interactive three-dimensional (3-D) graphical application, the system comprising: means for processing an interactive application, frame by frame, wherein each frame comprises a plurality of objects; means for interception of a set of graphical rendering commands generated by the processing of the interactive application; means for extraction of a set of geomtric and texture information from the intercepted set of commands per object; means for generating a modified set of graphical commands; means for rendering image frames from the modified set; means for pre-processing of the rendered image frames; means for encoding of the pre-processed image frames; means for controlling the means for generating, the means for rendering, the means for pre-processing, and the means for encoding based on a measure of encoding quality; and means for defining a level of detail of rendered images based on a pre-analysis of the extracted geometric and texture information, wherein the means for defining a level of detail of rendered images comprises a level-of-interest based control that is based on a region of interest segmentation process in which a relative visual quality value is assigned to objects in a respective frame.
