Abstract
In display systems employing analog monitors, the tearing artifact such that an window screen is divided into two parts showing different scenes can occur when the change of scenes in the moving pictures is very fast, but the frame buffer's refresh rate does not match the monitor's scanning frequency. It is especially noticeable at high frame rate. DVR system is a recently popularized visual monitoring system. The tearing artifacts becomes more serious since the frame buffer's refresh rate is very high due to the requirement of multi channel display in the DVR. In this paper, we propose an improved display system for windows-based DVR systems which prevents the tearing artifacts without deterioration of display speed performance. The efficiency of the proposed display system is verified through experiments.
