The morphologic observations of rats'livers showed that the liver impairment of rats receiving LCT was aggravated, while it was not seen in the rats receiving MCT/LCT.

That is why a delay, called Lag Compensation Time (LCT), is introduced between the real action and the display on the other side of the transmission pipeline.

In this algorithm, dynamic programming is used to calculate optimal local cosine tree during the LCT for signals, and the optimal entropy code is gained by the best partition of time axes.
