Abstract
A simple compositing system for combining sequences of images, including graphics and video images, records the sequences onto a disk recorder. A frame from each sequence in turn is processed by a digital picture manipulator channel and stored in a respective frame store. Once one frame from each sequence is processed and stored, the frames from the frame stores are combined in a video combiner to form a composite frame, which is read back into the disk recorder. All of the frames of the sequences are combined in this manner to form composite frames, the totality of composite frames producing a final composite image sequence stored in the disk recorder. The final composite image sequence is then transferred to an output device in real time.
