摘要：
A digital signal decoder system for receiving compressed encoded digitized video signals and transmitting decompressed decoded digital video signals with accurate expansion for various aspect ratios. This is accomplished through convolution multiplication carried out in 4-tuple parallel with 4-2 counters through a folding serial adder which creates a convolution sum of pixels of the motion compensated data stream to thereby expand the output video display to the desired aspect ratio.
