The CPM algorithm is applied and the data streams created by it is grouped into several sets by their important degree. With combination of streaming transmission technology, the data sets with different important degree are transmitted by respective channels. The network condition and user's needs are taken into account. The amount of data transmitted by the reliable channel can be changed dynamically and the real time characteristic of the system is improved. A new remote interactive display solution for 3D model over lossy network is also presented. Simulation results show the solution has better real-time performance under the premise of the user's visual need and the precision requirement.
