ABSTRACT:
A method of producing a composited video image based on depth uses a serial combiner to which a plurality of video input signals, representing video images, and priority signals are input. The video input signals each have an associated depth signal. The depth signals are sorted from farthest to nearest and a matrix control signal is generated from the depth signals. The matrix control signal is used to route the video input signals to appropriate inputs of the serial combiner in order from farthest to nearest. The priority signals are derived from the depth signals either serially or in parallel.
