an efficient video encoding approach is proposed to reduce the blocking effect. It employs a new logical realization structure of coefficient-by-coefficient adaptive DCT coding algorithm. Meanwhile

a simple but efficient adaptive controlling strategy is proposed to replace the exactly adaptation which is very complex. Also

to overcome the shortcoming that the performance of the adaptation decreases at low bit rates

an excellent fast algorithm for motion estimation which can efficiently improve the adaptive ability is proposed. The experimental results indicate that the performance of the new encoding approach has a marked improvement over the conventional DCT-based code.
