Abstract:
1. A method, comprising: receiving a video input from a video source coupled to a display; identifying a user interface to be displayed on the display and over the video input, wherein the user inference includes a stepped curved edge; generating an opacity mask to mix the video input with the user interface by setting red, green, blue (RGB) values, for pixels in the user interface, equal to an alpha value; and using a darkening parameter on a pixel in the user interface if a particular RGB value of the pixel matches a specifically-designated value for chroma-key operations, wherein a first group of pixels in the user interface have a first opacity level and a first chroma-key color, wherein the first opacity level is transparent or near transparent to allow the video input to be displayed on the display, and wherein a second group of pixels in the user interface have a second opacity level and a second chroma-key color, wherein the second group of pixels are located between steps of the stepped curved edge of the user interface, wherein the second opacity level is less than the first opacity level and the second opacity level darkens the video input to be displayed on the display but still allows the video input to be displayed on the display.
