Apparatus and method for combining first and second video streams and a border color into a combined output video stream using a multiplexer and a video combiner. The multiplexer receives the first and second video streams as input and outputs a selected video stream in response to a control signal. The video combiner receives the border color at a first input and the selected video stream from the multiplexer at a second input and outputs a combined output based upon a key received at a key input.

Effecting video transitions between video streams with a border

Combining first and second video streams into a combined output video stream by using a gradient table listing gradient values for pixels in a video frame to address a look up table of key values, and combining pixel values of the first and second video streams based upon respective key values read from the look up table.
