ABSTRACT:
Video graphics methods and systems can reduce objectionable ringing associated with composited user interface elements and video content, while at the same time preserve, to a desirable degree, the fidelity of the video content. In at least some embodiments, after the user interface elements are created, they are pre-filtered, before compositing, in a particular way that is designed to reduce undesirable ringing. Further, in at least some embodiments, during the compositing process, the left and right edges of the user interface elements are treated in a manner that is designed to reduce the ringing that would otherwise be induced by the left and right edges respectively.
