Digital radio and television is the development direction of the current TV, the as digitized conducted accelerating digital TV will replace analog television to achieve comprehensive coverage of digital television, the digitization of television brought the digitization of television media information, With the acceleration of the TV digitization process, computer data management system will be more and more widely-depth television media data management, in this regard, the television news media assets under the management of the development of computer network editing system is imperative. TV news department of a television in key sectors, the overall level of a television program production level. For television news programs, the pursuit of more than just show real-time novelty, for some valuable news storage management is also one of its main tasks. With the increase in television channels, the scale of production and broadcast news programs also growing some valuable news video and audio data changes with the times, its level of quality, the number of being constantly increased, which brought a great deal of difficulty for the news media asset management. Television news media asset network editing system, certain design research, with the ultimate aim is, to design efficient, reliable, safe television news media asset network editing system, the television news media assets of digitized management, up from a functional sub- the system can be divided into data upload, the audit media cataloging, media editing, media retrieval and download of several parts. In this paper, the first depth study of the various technologies used in the system of the B / S three-tier network architecture, SQL database technology, video conversion technology, data storage technology, and then use these key technologies, from network architecture design system functional design, data on design aspects of the design process and elements of the system analysis and design. Follow the software engineering ideas, in the process of system design, modular system as far as possible, adequate space is reserved for system upgrades and retrofits. Completion of the system design, the use of black-box testing methods of the system to do a more comprehensive system testing, test content includes system security, non-functional requirements such as reliability, and system registry, cataloging, upload a variety of functional requirements and several other aspects, the test results show that the system is basically designed to achieve the expected, to meet the requirements of the network editing of television news media assets, I believe that the use of the system will achieve better results.
