Abstract
A video processing device for generating an output video stream on the basis of two or more concurrent input video streams and a method thereof are described. Each input video stream comprises a sequence of input images. The output video stream comprises a sequence of output images. The video processing device generates each output image by merging a respective set of input images. The set of input images comprises one input image from each input video stream. The video processing device merges the input images in a series of merging rounds. Each merging round comprises forming an output tile by merging a set of input tiles, and writing the output tile to an output memory unit. The set of input tiles comprises one input tile from each input image of the respective set of input images. The output tiles written to the output memory unit represent the output image.
