Study On Data Transmission And Storage Of HLJTV Nonlinear Editing HD Network

In order to broadcast the 24th World University Winter Games in high definition, Hei Longjiang TV built a program which named HDTV's post-production nonlinear editing network. Basing on this program, the main purpose of thesis is to research the TV data transfer and storage technology about the high-definition programming homepage creation.At present in China as the largest post-production network HD programming, The content of this study is significant.. First, high-definition NLE test network set up for full channel Heilongjiang TV station broadcast HD programming system provides an important reference for the technical parameters, Become the cornerstone of the development of high-definition television.In this thesis, post-program production around the entire network of data storage and transmission were studied. Including high-definition network to build the overall framework for storage, server selection and design of specific storage technology, data encoding, transmission and HD NLE system for broadcast when the network maintenance and expansion of network security and so on.Compiled from the entire network operation and maintenance of non-perspective, Designed according to the actual needs of the most reasonable structure of the storage encoding and storage of multimedia data storage and transmission of the hierarchical management. In ensuring network security, so that the production and broadcasting high-definition screen and smooth, to the successful completion of Winter Games and the target program production and broadcasting, and Winter will be upgraded after the expansion of high-definition network to provide a stable network platform.
