Abstract	The rate of improvement to standard video encoders has slowed, but improvements based on purely new coding techniques are incompatible with the conventional standard. As an alternative solution, a new coding concept with semi-compatibility is described. I-picture is used for access and refreshment. To increase total performance, it is desirable to enhance the efficiency of I-pictures. The quality changes at the border of a GOP also need to be reduced. In response, we propose coding that is applied to the inter-frame processing on the border of a GOP. This applied method reduces the quantization error using motion compensated inter-picture processing. In this report, we verify the improvements in the efficiency and the compatibility of proposed method. As a result of our tests, we recognize that the total gain is maximally I.6dB in the PSNR. In general, the degradation of performance in standard decoding is less than its gain. Also with the proposed method, we find that the refreshment performance is sufficiently high.
