Abstract
Abstract The Video Insertion Processing System (VIPS) architecture provides the system architect with a modular and parallel approach to graphic processing. Using a core set of graphic modules, a wide range of graphic processing requirements can be satisfied. By providing the capability to support independent graphic paths, the performance can increase by N times for each set of graphic paths added. The use of independent graphic paths also increases the systems capability to meet real time response requirements. The key to the VIPS architecture is the ability to merge images from multiple frame buffers into a single display image. The final image is a result of selecting each pixel source based on the pixel's priority. This provides the graphics system with the capability of image overlay, underlay, merge and hide regardless of shape or size. A parallel pipelined approach provides the VIPS architecture with the capability of merging multiple images generated from the different graphic paths on a pixel by pixel basis without degradation of overall system performance.
