Of: Li in Nanjing, Technical Director TV News
Keywords: live news network Television news technology platform integration, refers to television news gathering, producing, broadcasting and other sectors integrate various technical resources and technical means, as used in television news production, to achieve optimal production process, the best broadcast to good effect. TV news channels, Nanjing integrated technology platform is mainly responsible for the three major broadcast journalist for part ("Nanjing Live", "Great news just said," "Social wide angle"), broadcast daily task of making up to 170min. If this third gear operation of the program production chain, respectively, closed operation, would be very wasteful of resources, but also split between these three sections of organic links can not form the channel edge. How to make use of various techniques to integrate a variety of technical resources to create a high standard of technical production platform to meet the news program's development, it became an issue.
Integrated technology platform Technology platform mainly collecting, editing, production, broadcasting, storage and re-use of four functions. Comprehensive news channel, the three main sections on the technology platform focused on the requirements and use different.
Table 1 Can be seen from Table 1, although this section shows the performance of several different forms, but the demand for technology platforms have many similarities, which is an integrated information technology platform for the integration of channel provides the premise.
(1) Nanjing Taiwan News program production process
news production and broadcast news-gathering network (editing, production) news studio (broadcast);
news production and broadcast news-gathering network (Edit) news studio (production, broadcast);
News gathering (satellite, telephone, etc.) news studio (production, broadcast);
News gathering and editing News Linear Guidance and Control Room (production, broadcast).
(2) Nanjing Taiwan News program data storage process
news production and broadcast news-gathering network (news editor) Media information
According to the needs of program production, we propose an integrated information technology platform and improving the production and broadcast network broadcast system functional requirements.
Integrated production and broadcast networks Information technology platform to broadcast the existing production network core, integrating other technical resources.
1, to system integration language network broadcast network. Now the production and broadcast networks are embedded in text network, but Nanjing is the first Taiwan News has written before the network system after the broadcast network, text, web and video / audio network into the system, affecting the network into full play.
2, to system integration of satellite broadcasting network your system. News Comprehensive Channel's "Big news just said," "social big wide" programs require extensive use of satellite TV resource, and if there is no satellite system broadcast network your system, use the satellite network, your system will greatly extend the record editing, production time.
3, in order to integrate production and broadcasting network storage systems (media information system). News media Information System's main role is the news information storage and re-use. A good news media information system is also enhanced integrated channel long-term competitiveness News powerful protection.

Optimization news production and broadcast network, add text network, satellite receiving systems, media asset management system, will greatly enhance news production and broadcast net. Use daily news production and broadcast network news business, whether it is equipment investment, or news production efficiency has been optimized and improved. News business with greater flexibility, timeliness requirements, the application of non-linear editing network to some extent so that the whole business to form a complete process; also achieved through network-based concurrent work, so that work efficiency is improved. With television, the network technology, a number of bottlenecks in the existing network such as the material is expected to be resolved on the download issue. Nanjing Taiwan centers on some cameras is based on the P2 card, the P2 card can achieve over time the material contained, in theory, up to 1:10, which means 10 minutes of material as long as one minute can be uploaded. However, the news business is different from other programming with special requirements, existing information networks in the business application of specific information support, there are still insufficient.
