A processor system and computer-implemented method may be provided for generating a composite video stream which may combine a background video and a foreground video stream into one stream. For that purpose, a spatially segmented encoding of the background video may be obtained, for example in the form of a tiled stream. The foreground video stream may be received, for example, from a(nother) client device. The foreground video stream may be a real-time stream, e.g., when being used in real-time communication. The image data of the foreground video stream may be inserted into the background video by decoding select segments of the background video, inserting the foreground image data into the decoded background image data of these segments, and by encoding the resulting composite image data to obtain composite segments which, together with the non-processed segments of the background video, form a spatially segmented encoding of a composite video.
