Abstract

MPEG coding algorithm is a full motion compensated DCT. In MPEG coding, the video sequence first divided into groups of picture of frames (GOP), (I,P,B frames). The algorithm for adaptive I frame position, depending on the indexing technique, In This paper an algorithm was developed to variable GOP length which was resulted in minimizing the bit rate with average 10% to 15% from the classical MPEG coding technique while keeping the same SNR with respect to the standard MPEG coding algorithm.
