Abstract
The present invention relates generally to video communication systems, and more specifically to a method and device for adjusting properties of a graphical overlay for a video stream, the adjusted properties being at least one of a position, a degree of animation and a color composition of the graphical overlay and the adjustment is based on a scene depicted by the time period of the video stream. The adjustment is performed if an estimated bitrate for transmitting an encoded bitstream comprising the time period of the video stream and the graphical overlay exceeds a predetermined upper threshold bitrate for transmitting an encoded single bitstream comprising the time period of the video stream and the graphical overlay.
