| With the continuous development of the society, Video communication has beenintegrated into all aspects of people’s life, such as tele education, tele medicine, videoconference, radio and television broadcasting and so on. But the existing videocommunication and business forms gradually can not meet the needs of consumers, aswell as the insecurity IP network and limited address make that the videocommunication must have new breakthrough and development. This article is studiedon the future network architecture, proposing the video communication of ideas andnew solutions.Firstly, the research status of video communication both here and abroad isintroduced to understand the development process. According to the developmentneeds in different applications in the field of video communication, the prerequisiteperformance requirements of video communication are analyzed in many aspects,such as safe and reliable, real-time and stability, popularized and personaldevelopment. Secondly, to study the theory and technology involved in videocommunication, technical features, all kinds of video image compression coding ofthe video communication control protocol and standards as well as the videotransmission quality by using the error control technology, provide the theory supportfor the design and implementation of the follow-up. Thirdly, according to the basicrequirements of the future network architecture, putting forward the future connectionoriented network framework, designing the hierarchical structure of concrete and thebusiness address allocation of COFN, and indicating how to realize the exchangeCOFN routing. On this basis, putting forward the design scheme of videocommunication, including system structure designing, establishment and revocationof video communication, implementation of business management; and exploring the future of radio and television broadcasting interactive and multi-service supported.Finally, the Quartus II software development environment and ModelSimsimulation tool features and methods of using them are introduced. By using VerilogHDL hardware description language establish module design for business applicationmodule, point-to-point and multipoint mode link. Then writing testbench for thosemodules and combining with ModelSim simulation software, to realize RTL behaviorlevel simulation for these modules. The simulation results show that the establishmentand revoking of the video communication can be realized in function. The researchedworks in this paper provide certain reference for the study of the development ofvideo communication. |
