subject: Television Programming: The Digital, Network Evolution - Program Production, Digital, Non-code [print this page] Digital technology, network technology led to the development of TV revolution.
Recent years, digital television has been noticeably accelerated, broadcasting from the shooting. Post-production, storage, transmission being broadcast to digital, networked in full swing, producers of the program put forward higher requirements.
With the television business continues to develop, an increasing number of channels, channel professional, part personal, boutique programs has become the development direction for each television program. The channel, part for the publicity, brand, increasingly high demand on the program production, non-code system instead of the traditional linear editing has become a trend.
Realize a high programming efficiency, low cost
With digital technology and multimedia technology, there have been a non-compiled computer system platform, it has a powerful, simple, highly integrated, can be networked resource sharing and so on. After years of development of non-compiled function gradually improved the system has been widely used in television postproduction. However, some stations will reflect the use of non-code system "cost becomes higher," "inefficient," and so on, really bad non-code system to use it? So why all the national television networks in the introduction of non-code system? What is a non-code where problems?
Let us first look at the problem: the high cost and low efficiency is the same problem when using non-compiled, there is no unified file format, download the program takes time, and a long, inefficient, At this time the cost of independent accounting on television, due to higher occupancy costs resulting from resources, so in general there will be a production of the program on the use of non-series high cost and low efficiency argument. This issue, Avid General Manager of Beijing Office of China Mr. Li Qing said: "The non-Code itself is a very efficient product, the reason for creating the current situation is due to old and new equipment, new and old technology when combined with problems, if these problems can be resolved, then the efficiency of the entire production process is very high. "Yes. According to HC Network 2006 survey on the existence of quality, now or in tape-based storage media, shown in Figure 1. At present the use of tape still plays absolutely television role, blue disc and P2 card is only very small amount of semiconductor applications.
Equipment now used in Figure 1, the storage medium
Although it occupies a tape storage medium in the mainstream, but the future is a non-band of the era. Television program production to meet the next band of the whole process without trend, the video equipment manufacturers introduced a variety of storage media. Sony introduced a Blu-ray, Panasonic introduced the semiconductor P2 cards, Thomson, JVC, Hitachi, Ikegami, Chinese fine record so proud of the hard disk is introduced.
With the rapid development of IT technology and to fully penetrate the field of professional AV, computer platform based on IT technology television at all levels to get more and more widely used, but the traditional linear tape-based workflow difficult to adapt to TV on the efficient, low-cost programming, especially in ENG, EFP, which produced no zone-based system is a trend, but now tape production system is still the mainstream, so the tape with the new storage medium will be a coexistence and the gradual replacement process.
No band of three kinds of storage media now no one absolute advantage, also have certain users in a certain period of time will be the three pillars of the situation, and technological superiority, cost-effective and so will be the key to winning.
To improve the efficiency of program production and broadcasting, the ocean full document proposed solution. Full documentation includes three aspects, first editing stage, the second transmission stage, third stage of the terminal to receive and play. If the use of full documentation, the biggest advantage is that can be done over time, can do asynchronous processing, can match the current network environment, various physical and operational rules of operation, the domestic broadcasting industry 10 years in the entire documentation phase of the ocean done a lot in many areas, such support is made of this industry IT systems, such as P2 and Blu-ray, the device is extended not only to support a variety of roles, and from SD to HD is different support. Ocean in the years established a number of national news and post-production system nonlinear.
Future post-programming the transition from the linear to nonlinear, with the gradual realization of a trend is the trend, the only way to truly realize the high programming efficiency, low cost.
