大規(guī)模DVE場景對(duì)等傳輸機(jī)制研究新進(jìn)展
[Abstract]:Objective at present, the virtual world built on the Internet is becoming larger and larger, but with the limited bandwidth of the real network, Real-time transmission of massive and complex virtual scenes is always a "bottleneck problem" which is difficult to solve. Methods firstly, the main technologies of large-scale 3D virtual scene transmission were summarized, and then the key technologies such as lightweight and streaming technology of large-scale virtual scene, P2P-Cloud (Peer to Peer-Cloud network architecture, resource discovery / neighbor discovery strategy, were discussed respectively. The virtual scene data distribution strategy and mobile network scene transmission with different network architecture are reviewed in detail. The results illustrate the relationship between the main technologies of virtual scene transmission and analyze their advantages and disadvantages as well as the key problems to be solved by comparing the existing classical results. Conclusion from the perspective of scene preprocessing of virtual scene transmission, cloud based hybrid network architecture and scene transmission in mobile network, this paper makes a prospective outlook.
