Abstract: This paper introduces two available methods to denote the efficiency region of ES. They are the Windows region data structure and the polygon list. The key technologies for data transmission are discussed, which are data transition, the selection of data transmission way and compression of data. It makes a comparison of two region denoting structures, the results can be used for how to select transmission way. The technologies are Applied in some systems successfully, the new method gave out in this paper is approved to be simple and facile.
