Network Analysis And Realization Of Nonlinear Editing System In TV Station

Nonlinear Editing System is a fast-developing technology in 21st century, which combined program editing and information science. As it appeared, the efficiency of program editing improved a lot. Recently, as the information science developing, the combination of information science technology and program editing was born; it named Nonlinear Editing Network System. The system includes media collection, program edit and program broadcast. Every department of the TV station can share the media material and other files over this system.This paper first introduces the popular construction of Nonlinear Editing Network System, and then detailed analyses the Service-Oriented Architecture (SOA) which includes Enterprise Service Bus (ESB) and Enterprise Media Bus (EMB). The Enterprise Service Bus (ESB) has a broad application in some fields. The Enterprise Media Bus (EMB) is a news suggestion special for the TV station network. It provides a big support to Enterprise Service Bus (ESB). The analysis for Enterprise Media Bus (EMB) is an important part of this paper.Firstly, based on the construction of Enterprise Service Bus (ESB) and Enterprise Media Bus (EMB), a overall project applied to TV Nonlinear Editing Network System is presented. Then we discuss the construction and the function of Enterprise Media Bus (EMB). Following the comparison between several schemes we propose one scheme for the construction of Enterprise Media Bus (EMB) which is most appropriate for the TV station's net-construction.After we present the network construction which is based on the two buses frame, we propose a scheme of Nonlinear Editing Network System, in which we use lots of new information science technology such as Fiber Channel Correspondence, Storage Area Network etc. During the building of this net we faced some problems, such as the rationalization of network fame, the security of net. In this paper, we give the answer to dispose these problems.At the end of this paper, we build a real Nonlinear Editing Network System. We test this system to prove that it can be used in TV station's edit work.This paper is very useful for Nonlinear Editing Network System building. And it can also be seemed as a good reference for technician who works in TV station.
