Dalian Tv Station Nonlinear Visual Audio Editing Network Construction

Developing at very fast speed, computer technology forces the methods of TV programming a great progress. Non-linear editing system becomes the standard configure of TV programming bit by bit. The maturity of magnanimity-storage and FC transmission technology also turns it into reality that non-linear editing system operating on network. More and more TV stations begin to adopt non-linear editing network to complete news and subject program. Comparing stand-alone non-linear editing system, non-linear editing network can more improve working efficiency and reduce the program cost by storing material one place and sharing it. Network can widen the method of program exchange, avoid repeat operate, ameliorate the mode of program communion and improve the AV technique quality.TV technology is just a passing phase now. Analog coexists with digital and stand-alone coexists with network. The purpose of TV technology is digital and network. It is profundity signification to realize the course of network and to explore the meaning of network.The article analyses the non-linear AV editing network system in detail using Dalian TV station non-linear AV editing network as an example. In the first part of the article, the author introduces organization and technology principle of non-linear AV editing network system. Furthermore, in the second part, the author makes a deeply discussion and research on the design scheme of Dalian TV station non-linear AV editing network including the double-net framework, the digital compress technique, the virtual storage technique, the choices of digital compress format, the account of terminal stations, the manage functions and security of the system, etc. Finally, in the third part, the author introduces the progress of non-linear AV editing network in the future, showing the choices of compress format, software function, i/O interface, whole system of programming and broadcast, combining with Internet and interactive TV, points out the direction of tomorrow TV technology system.
