Design And Construction For Hd News Production Platform Of TV Station

High Definition Television (HDTV) gives people wonderful visual enjoyment. It is a development direction in broadcast and television, and also an important part of the culture industry. Promoting High Definition Television broadcasting development is an important work the"12th Five-Year Plan", CCTV, Beijing, Shanghai and many TV stations are speeding up station operations system of high-definition construction.The traditional business of TV station such as editing, broadcasting, and storing is facing a series of challenges in the"Three network convergence"process and HD transform process.This article researches and explores how to design and construct the "News Program Production Platform" of TV station.Firstly, this article uses the project management ideas to solve the existing problems in news program production system such as resource management, data collection. Secondly, this article introduces the news program production platform overall frame design, puts forward the network, high-definition, high cooperative framework model. This article also discusses how to use project management methods in the entire platform module design. At the same time, the author points out that the program material is not good enough for resource management, organizational management and process management. Using the news script as a main line in news program production platform is much better. Finally aimed at the"Three network convergence"of platform technology on the new requirements, the author gives a platform design in information collection and dissemination, much channel news studio, multi-vendor synchronous communication platform, and the data security solutions.These ideas and programs have been applied in HD news program production platform of Heilongjiang, Guangdong IBC system and many other projects.1. Using the idea of project management in platform design can effectively improve the data management, control and analysis;2. In the whole platform design, Using methods of project cost management, project management, project risk management ensure the platform project implementation;3. The news script can make each module link closely and conveniently, so it improves the efficiency of news production;4. Using MOS protocol can solve the problem of interconnecting between different manufacturers and different systems. It is very important for real-time modification and real-time broadcast; The IDA (Intelligent Dual Access) engine is the core of the media content data security architecture. It effectively enhances project security assurance. This engine can be used in broadcasting, integrated production, document backup, and so on. It is suitable for HD news production in the"Three network convergence".At last the article has made the summary and the forecast. The author thinks the design method in news program production platform can also be multiplexed into other business systems in television.
