ABSTRACT = {Studies show that encoding technologies in H.264/AVC, including prediction 
and conversion, are essential technologies. However, these technologies are more 
complicated than the MPEG-4, which is a standard method and widely adopted worldwide. 
Therefore, the amount of calculation in H.264/AVC is significantly up-regulated compared 
to that of the MPEG-4. In the present study, it is intended to simplify the computational
expenses in the international standard compression coding system H.264/AVC for moving 
images. Inter prediction refers to the most feasible compression technology, taking up to 
60% of the entire encoding. In this regard, prediction error and motion vector information 
are proposed to simplify the computation of inter predictive coding technology. In the 
initial frame, motion compensation is performed in all target modes and then basic 
information is collected and analyzed. After the initial frame, motion compensation is 
performed only in the middle 8×8 modes, and the basic information amount shifts. In order 
to evaluate the effectiveness of the proposed method and assess the motion image 
compression coding, four types of motion images, defined by the international 
telecommunication union (ITU), are employed. Based on the obtained results, it is 
concluded that the developed method is capable of simplifying the calculation, while it is 
slightly affected by the inferior image quality and the amount of information.},
