A real-time video production technique using recursive techniques adds an output framestore, a feedback storage unit and a synchronized controller to a pipelined video processing system. Partial composites are stored in the feedback storage unit while complete composites are stored in the output framestore....http://www.google.com.tw/patents/US5986717?utm_source=gb-gplus-share專利 US5986717 - Real-time video production using recursive techniques
