Abstract

With the development of modern information technology, Telecommunication network, Computer network and TVBroadcast network are converging rapidly. And the three networks form the base of the modern information industry. Although this convergence is considered a support of all services, their convergence doesn't indicate that physical networks will integrate completely. No one of these networks can take the place of others. In fact, this concept inclines to the convergence of services and the infiltration of function among these three networks. This paper give a deep analysis about the characteristic of GIS in this convergenced environment, and discuss the difference compared with traditional WebGIS. Suppose iTV is the terminal service platform of the three networks' fusion, this paper make a discussion about frame and modules of this kind of GIS. The key techology about iTV-GIS includes embedded operation system, middleware and so on. Set-top box as the most important device to run iTV-GIS program has its particularity. A development phase in virtual mechine before hardware importing is necessary. Then a antetype design of iTV-GIS is given as an example at the end of this paper. This research is just a beginning for developmeing GIS on the platform of the three networks' convergence. The subjects mentoined in this paper is just one implement on iTV virual platform, but wish such attempt will bring GIS to a new circumstance, and supply some material for the research later.
