With the development of radio and television information technology, it has become an inevitable trend for computer information technology to enter the field of radio and television. Information technology not only brings us open ideas, free knowledge and novel technical methods, but also brings a great change to the radio and television industry in terms of function, content, transmission mode and the role orientation of radio and television workers. The construction of computer network environment is a long and difficult process. Batch after batch of emerging things are rising, and wave after wave of business models are being constantly innovated. Therefore, how to control the development direction of the computer network environment and how to survive in the contemporary computer network environment is a challenge that all walks of life must face. If radio and television, as an old industry, wants to smooth the trend of the times, it must integrate into it, collect all kinds of information technology resources and seek long-term and healthy development.

1 Characteristics of radio and television information technology resources

The so-called virtual studio is a new TV program production tool. Virtual studio technology includes camera tracking technology, computer virtual scene design, color key technology, lighting technology and so on. Based on the traditional color key matting technology, virtual studio technology makes full use of computer three-dimensional graphics technology and video synthesis technology to make the perspective relationship of three-dimensional virtual scene consistent with the foreground according to the camera position and parameters. After color key synthesis, the host in the foreground looks completely immersed in the three-dimensional virtual scene generated by the computer, And it can move in it, so as to create a realistic and three-dimensional TV studio effect. Virtual studio, a brand-new TV program production tool, is an important technological innovation in the field of radio and television under the contemporary computer network environment, and reflects the characteristics of the times of radio and television information technology resources.

Mainly in the following aspects:
1) The acquisition and reuse of information technology resources saves the capital cost of program production: Virtual Studio simulates the real situation through computer network technology on the premise of ensuring the viewer's experience, which greatly saves the production cost of the program, Traditional complex programs can complete the whole process of information transmission and situation simulation by using several computers in the computer network environment.
2) The effectiveness and convenience of information technology resources is that the program production cycle is greatly reduced and the time cost is saved: the traditional TV program production process is very complex. If different departments form effective communication channels, it will greatly prolong the program production cycle, which is time-consuming and laborious. However, in the computer network environment, the communication between various departments can often be completed in only a few seconds, and various opinions and suggestions will be fed back in time. Therefore, many "detours" are avoided in the process of program production, which greatly reduces the production cycle of programs, saving time and seizing market opportunities.

2 The influence of contemporary computer network environment on radio and television information technology resources

1) The traditional fixed program production mode is replaced by the modern free program production mode: through the above introduction to the virtual studio, it can be seen that the process of making radio and television programs using computer network is very intelligent and highly free. In this new free production mode, we can sit together in the "virtual studio" anywhere at the same time. With the continuous development of information technology, the traditional TV studio is no longer the main place of TV production. Instead, it is a new virtual studio environment composed of information resources through organic combination in computer network, which has to be said to be a great transformation and innovation of information technology resources to the traditional production process.

2) High integration and deep classification of information technology resources under the computer network environment: the editing and production of radio and television programs need a variety of information technology resources, so how to store and manage these resources is very important. Under the computer network environment, the storage and management of information technology resources has become more and more intelligent and humanized. As the carrier of many things, information technology resources are attached to the powerful computer network, which can reflect its advantages such as large capacity, small occupied space, fast transmission, wide coverage and so on. To sum up, the computer network environment has carried out a high degree of integration and in-depth classification for radio and television information resources, ensuring that various information technology resources can still maintain a high degree of correlation between the cross and vertical.

3) The transmissibility of radio and television information technology resources has been greatly strengthened: the transmission of modern radio and television information resources is divided into time and space. Taking computer network as the communication medium can make the radio and television information technology resources have a qualitative improvement in time and space. Today's computer network is not only an advanced technology, but has become a navigation light to guide the development direction of the world and an important channel for the acquisition, exchange and sharing of information technology resources.

4) Contemporary computer network technology has improved the timeliness and sharing of information technology resources: the reference and application value of information resources lies in timeliness and sharing. A timely radio and television information resource can multiply its value through dissemination and transformation, Sharing refers to the sharing of knowledge and information among different individuals through the transmission of information resources across time and space. Nowadays, the development of computer network technology has broken the traditional space-time limitations, so that all kinds of information can retain its timeliness and sharing to the greatest extent even if they are intricately intertwined.

3 Conclusion

To sum up, in the contemporary computer network environment, people's utilization of information technology resources is getting higher and higher. The above takes the virtual studio in radio and television as an example, which well confirms the author's views and opinions on the advantages of contemporary computer network, such as low cost, high timeliness and low redundancy. Nowadays, the degree of informatization has become a crucial factor in measuring the competitive strength of a country, nation and region. We can even think that informatization has become a pronoun of the times, and the best embodiment of this pronoun is the high utilization of information technology resources by computer network technology. Nowadays, China's broadcasting industry is developing rapidly, which is inseparable from the effective integration of radio and television information technology resources by computer network. Therefore, in the contemporary computer network environment, the characteristics of information technology resources will be more obvious, and its impact on the development of radio and television will be deeper and wider.
