ABSTRACT:
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. The output framestore provides a preview video during the video processing. For automatic assembly where the feedback storage unit has a length of many frames the complete composites are stored also in the feedback storage unit and a multiplexer is used to select the complete composites either from the output framestore for each new complete composite or from the feedback storage unit otherwise.
