Cloud computing: Radio and television applications are still starting

Cloud computing is convenient, flexible, high performance, low cost, represents the direction of future IT development. The combination of three nets and the construction of next generation radio network provide a rare opportunity for the development and application of cloud computing in the field of radio and television. At the same time, the introduction of cloud computing technology will accelerate competition in the field of radio and television, improve its competitiveness, technical level and service capabilities.

Sharing media to enhance efficiency

The advantages of cloud computing technology in radio and television applications can be embodied in the following three aspects:

One is content, you can share media resources, realize the maximum utilization of content resources. The field of radio and television is the natural need of cloud computing technology and services, the main reason lies in its massive audio, video file storage, conversion and use. Radio, television, program integration platform, cable TV operators have a wealth of media, content and other resources, but at present due to the technical system capacity constraints and island-type media resources management system, resulting in a large number of media resources inefficient use. The existing Content resource management system for cloud computing, the establishment of radio and television program content resource pool, can achieve the digital content resources, mass storage, data sharing, the formation of a strong search and content production capacity, improve resource use efficiency, enrich program content, reduce operating costs.

The second is infrastructure, cloud computing technology in the IT infrastructure scalability and utilization performance more excellent features. Before using cloud computing technology, servers and workstations are exclusive, utilization is generally only 5%~10%, and using cloud computing can be improved to 70%~80%. Moreover, the system based on the traditional architecture can not accurately calculate the carrying capacity of the system, if large live events often face the problem of insufficient resources, and cloud computing can make up for this, when needed to expand the scale of resources, do not need to idle waste.

Third, the service, can effectively cope with the three-network integration and the next generation of the challenges of wide grid construction, to help radio and television to digital network and two-way transformation, the provision of comprehensive information services to promote the integration of traditional media and new media. Cloud computing in the strengthening of new media audio-visual content production and development of platform-oriented, multimedia, multiple terminals of the new program shape has advantages, can be very good to solve the video, audio file format in different terminal conversion problems, speed up the spread of the program and enhance the user experience. In addition, cloud computing technology can be used to explore user data, to help radio and television analysis of user behavior, to provide a time slot, the crowd, more targeted programs and advertising.

Security for the first progressive development

Although cloud computing for radio and television applications have a natural advantage, but because of the particularity of radio and television, the promotion of cloud computing still faces some difficulties. First, broadcasting, television is the party and the country's important public opinion propaganda position, is to the social spirit, the culture, the economic development most influential mass media, the safe broadcast is the Chinese radio and television domain top priority, its security requirement is very high, this is the cloud computing needs to conquer in the technical level main problem. Second, the cable television industry's regional segmentation is also very obvious, the phenomenon of fragmentation in a short period of time can not be eliminated. Third, radio and television has long formed a closed development model, making its idea obsolete, poor technical innovation, and even some people for the introduction of cloud computing advanced technology and mode of skepticism.

For cloud computing in radio and television applications, we should follow the principle of security first, step-by-step, for a specific business to build private cloud, mixed cloud and public cloud, and gradually develop.

First, you can start with the virtualization of office systems, servers, reduce hardware and software procurement costs and energy consumption; Secondly, in the process of high it technology requirements, such as television, package synthesis of radio programs, transcoding, automatic technical examination, multimedia retrieval, news automatic disassembly, etc., the introduction of clustering operations, virtualization, distributed processing technology, Improve the operation efficiency and production quality of the related business; third, starting from Non-core business, the gradual transition to the core business of the cloud, such as television program recording, broadcasting and advertising management; four, for cloud computing demand strong media cloud, can first build the regional media cloud, then through the corresponding standard protocol to make different media cloud interconnection, and gradually form a national media cloud; V, do a good job of cloud planning, because the new a well-planned, reasonable structure of the information system than to transform an old system can not meet the needs of a much easier.

Cloud computing for radio and television, for the whole society are new things. Although its application in the current is still in the initial stage, there are many deficiencies, but it represents a new generation of information technology wave, I believe that in the near future, it will revolutionize the radio and television industry, to bring more development of radio and television, to bring better services to users.

Microscopic point

@DVBCN Digital TV Chinese Network: Cloud terminals, cloud applications, cloud platforms have emerged! Three network integration, cloud service power in the terminal, the focus of competition is also focused on the terminal. The future will be the "intelligent terminal + cloud services" ecosystem, the future of competition, including content resources, such as the competition between the ecosystem.

@ Take Cloud era: CCBN2012 will be in the background of three nets to fully display SARFT NGB project The latest achievements and radio and television industry in the cloud computing research results. Shang, deputy dean of Guang Ke Yuan, said that storage and sharing through the cloud is a major development direction of radio and television.

@ shenzhen Chen Yu people: IPTV Massive coverage of the number of users, clear image quality, user-oriented strong interactive performance, users will be pulled back to the television, is the television station in the three network integration of the largest new opportunities.
