Detection and repainting of semi-transparent overlays

Abstract:

A server includes at least one processor configured to execute a media application to provide media streaming that includes at least one video stream and at least one overlay on the at least one video stream. A portion of the media streaming is redirected by providing a placeholder to indicate positioning geometry of the at least one video stream within a media window, with the placeholder to include the at least one overlay. The processor detects the placeholder and determines positioning geometry associated therewith. A color and an alpha blending factor of the at least one overlay is determined based on calculations involving different colors of the at least one underlay at different times.
