China's DVD is restricted by foreign patents, which makes it very urgent to have independent intellectual property rights in the home appliance industry. EVD is a "new generation of high-density digital laser video disc system", which has passed the appraisal of new products and technologies by the State Economic and Trade Commission and scientific and technological achievements by the Ministry of Science and Technology. This is also an information home appliance product independently researched and developed by China with independent intellectual property rights.
"A new generation of high-density digital laser video disc system" is the crystallization of major technological innovation projects approved by the State Economic and Trade Commission. Invested by some domestic backbone home appliance enterprises, undertaken by Beijing Guo Fu Digital Technology Co., Ltd. and piloted by Shanghai Radio and Television Group. EVD is the product of the combination of household appliances and computer technology, and it is a powerful and widely used new consumer electronic product. It integrates players for playing high-definition digital programs, hi-fi and surround sound, ultra-large capacity karaoke, video recorders, game consoles, set-top boxes, videophones and computers, which can meet the needs of ordinary families and can also be used as test and demonstration equipment for digital TV production and sales.
Compared with VCD and DVD systems, the technical advantages of EVD are obviously higher than them. It fills the gap in the storage and playback of high-definition programs in China, which is the first achievement in China, especially the audio compression algorithm with independent intellectual property rights, which can generate better audio than Dolby AC-3 at the same bit rate and reach the advanced level in the field of audio compression in the world at present. EVD is not a so-called super DVD. According to experts, EVD is a brand-new technical system standard specially developed for information appliances, which is similar to the European open and interactive broadcasting standard MHP. According to reports, EVD can support networking, games, multimedia devices, set-top boxes and other functions. According to modular design, OEMs can decide to add modules flexibly according to functional requirements, which is in line with the trend of gradual integration of broadcasting and Web. Ordinary DVD is just an isolated product, while EVD supports network function, flexible subtitle function and strong interactive ability. In addition, the system is also compatible with VCD, Super VCD, DVD and other common video formats. The system also adopts digital watermarking technology with independent intellectual property rights, which can effectively protect the copyright of the program. The whole system includes 22 invention patents and 5 sets of software. Of course, the biggest feature of EVD is its high definition and large storage capacity. The picture quality can be up to 5 times clearer than DVD, supporting all TVs with more than 800 lines.
At present, the relevant departments of our country have adopted EVD as an international standard, and are ready to formally submit it to the International Organization for Standardization of the International Electrotechnical Commission.
Nowadays, digital audio-visual products, including digital TV, portable digital terminals integrating personal communication and personal information processing, and home information network products integrating computers and household appliances, have become the main driving force of the new round of production and consumption upsurge of electronic information products. Correspondingly, the electronic information industry has also begun to "shuffle" on a global scale. Large foreign enterprise groups have long been "moved by the wind". Microsoft has developed products that integrate games, DVD players, Internet access and information processing functions, with the aim of integrating home appliances and information products into the market of audio-visual products and home information network products.
At present, China has the largest DVD player market in the world. According to experts' prediction, the total sales volume of EVD will reach120,000 vehicles. In addition, as an auxiliary product of digital TV design and production, the corresponding market capacity of EVD is about 654.38+0.6 billion yuan. Considering the promotion of EVD to integrated circuits and other related industries, it will bring economic benefits to EVD. Experts believe that the domestic market capacity of such products will reach 654.38+000 billion yuan in the near future.
The success of EVD research and development has solved the technical source problem of China household appliances enterprises in the fields of digital audio-visual products and home network products. At present, with the promotion of Shanghai Radio and Television Group and other enterprises, EVD series products will form an industrial scale this year. This technical standard has not only won the full support of the backbone enterprises in the domestic digital optical disc industry, but also won the unanimous support of Taiwan Province Province 19 large household appliance enterprises. The process of EVD becoming a national industry and an international standard has been fully promoted by the China Municipal Government. At the same time, the industrialization of EVD has also become a successful attempt to innovate in the field of high-tech industrialization in China.
In the disk drive market, if the video recorder is compared to a bicycle, VCD to a motorcycle and DVD to a mini-car, then EVD can be said to be a sports car with excellent performance, which will end the DVD era. In the product of DVD player, its main function, like color TV, requires high definition, so the definition of EVD can be imagined. Now China's digital TV market is gradually starting. The essential feature of digital TV is to realize high definition of digital TV programs, and the corresponding multimedia audio and video products should also be able to realize high definition. EVD, which is five times clearer than ordinary DVD, just caters to the requirements of the digital TV era, and of course becomes the best choice for people's laser video disc players in the digital TV era.
