In the field of digital audio and video in China, foreign manufacturers have successfully occupied the upstream of the industrial chain by virtue of the control of technical standards, and made a lot of profits by collecting copyright fees and patent fees. After AVS became the national standard of digital video coding in China in March last year, China's digital audio technology has also made a breakthrough this year.
65438+1On October 20th, the Ministry of Information Industry, the State Administration of Radio, Film and Television and other ministries and commissions and the Guangdong Provincial People's Government jointly held a conference on accelerating the industrialization of digital audio and video and publishing digital audio standards in the Great Hall of the People. At the meeting, the Ministry of Information Industry officially released the China digital audio electronics industry standard with independent intellectual property rights-technical specification for multi-channel digital audio coding and decoding. The promulgation and implementation of this standard will strongly promote the development of digital audio and video industry in China.
Audio standard fills the gap in China
"Digital audio-visual industry is an important part of the information industry, and cultivating digital audio-visual industry clusters is an important task of the information industry during the Eleventh Five-Year Plan period. The digital audio and video industry has increasingly become an extremely fierce field of standard competition, and technology patenting and patent standardization have become its characteristics. " Lou Qinqin, vice minister of the Ministry of Information Industry, said.
Digital audio codec technology is the core technology of digital audio industry. However, technology has long been in the hands of foreign companies. At present, China audio products related enterprises pay hundreds of millions of dollars of digital audio technology license fees to foreign enterprises and organizations every year. Multinational companies often monopolize the market through the formulation of control standards, maintain their dominant position and obtain high and stable income.
Faced with these situations, Xu Qin, director of the High-tech Industry Department of the National Development and Reform Commission, said: "At present, China's audio-visual industry is facing serious pressures and challenges such as intellectual property rights and anti-dumping, and it urgently needs innovative development of the audio-visual industry. Digital audio and video coding and decoding technology is one of the key core technologies of audio and video industry. Mastering independent intellectual property rights in this field is of great significance for enhancing the core competitiveness of the industry. "
With the application of digital TV, IPTV, digital broadcasting and other media, digital audio technology has increasingly become the focus of attention of industry manufacturers. If China people really want to hear their own voices, domestic manufacturers must take the initiative in technology, and it is imperative to formulate the China standard for audio technology.
Based on this, Guangzhou Guangsheng Digital Technology Co., Ltd. independently developed the internationally advanced multi-channel audio codec technology (DRA), and applied for two international invention patents and 12 domestic invention patents, which filled the gap in this field in China.
This technology has the advantages of high compression efficiency, good sound quality, low decoding complexity and strong fault tolerance, and can be widely used in digital TV, digital audio broadcasting, broadband multimedia and mobile multimedia. Lou Qinqin spoke highly of this: "Multi-channel digital audio coding and decoding technical specifications have the intellectual property rights of digital audio core technologies. The promulgation of this standard will provide favorable technical support for the digital audio industry and play a leading role in the rapid breakthrough and development of digital audio in China. "
Industrialization is the key to breaking ice.
At present, the audio industry standard has just been established, and it is urgent to form a benign development and industrialization pattern. It is difficult for a single enterprise to form a complete industrial chain. The audio industry standard is only the first step in the development of audio and video industry in China. Industrialization is the key to break the ice of international patent monopoly.
Zhong Yangsheng, executive vice governor of Guangdong Province, said in an interview: "The symbol of the success of digital audio and video industry is not the release of standards, but the key is to go to the market and form industrialization." To this end, the Guangdong Provincial Government has set up the Guangdong Digital Audio Technology Project Promotion Leading Group, which cooperates with the National Development and Reform Commission, the Ministry of Information Industry, the State Administration of Radio, Film and Television, the Ministry of Science and Technology, the State Standardization Administration and other relevant ministries and commissions to make great efforts to coordinate the work in five aspects: standard formulation, technological innovation, intellectual property disposal, verification, sampling presumption and application promotion.
Guangdong's huge audio and video industry base and market demand are good carriers to support the industrialization of technical standards. Taking Guangdong as a pilot, in 2006, Guangdong Province promoted the industrialization and application of DRA audio standard as a whole, forming a complete digital audio and video industrial chain and application area integrating chip design, whole machine production and application development.
According to Zhong Jinsong, general manager of Guangdong Guangsheng Asset Management Co., Ltd., Guangzhou Guangsheng Digital Technology Co., Ltd. actively promotes the industrialization of digital audio technology while developing DRA audio technology, accelerates the formation of digital audio industry chain, and makes DRA technology enter satellite live broadcast, mobile digital multimedia broadcasting, digital TV, IPTV and other application fields.
We must vigorously promote the application of technology.
The audio coding of DRA is only the basic standard in the audio field. Whether it can succeed in the market still needs the joint promotion of the government, industry and enterprises. The application of DRA technology is mainly in two fields, one is radio and television, and the other is audio and video consumer electronics.
