EVD is a DVD upgrade technology independently developed by China enterprises with the strong support of the Ministry of Information Industry, in order to resist the restriction of DVD technology on China enterprises. EVD's HD technology passed the national technical appraisal in early 2002, and was successfully applied to the production of home HD DVD players by DVD players such as Shinco, SVA and Amoi. EVD disk drive was launched in June 2004 at 5438+ 10, and passed the high-definition inspection by the Ministry of Information Industry in September 2004. SVA's EVD388 was rated as "the most popular home appliance product in 2004" by Sohu. The new EVD8830 was named "Top Ten Innovative Products in 2004" by People's Daily.
At present, EVD has more than 20 national invention patents and 10 international invention patents, and its technology is in the leading position in the world.
2. Where is 2.EVD better than DVD?
The resolution of DVD is 720×576(PAL system) or 720×480(NTSC system), and the effective number of pixels of each picture is 350,000. The output signal of EVD disk drive is in 1080i and 720p HD format, with 2.07 million effective pixels, which is more than five times that of DVD.
The color saturation and brightness of EVD picture are much higher than that of DVD, and the color reproduction ability is several times that of DVD, so the picture is very delicate and realistic. For example, if you watch it through EVD, five small black dots close together on the screen are clearly visible, and if you watch it through DVD, it is a big black dot.
EVD audio compression adopts ExAC technology, which can realize high fidelity and surround sound at the same time. In the evaluation of the Ministry of Industry and Information Technology, the sound effect of EVD is 4.7 points (out of 5 points), which is 0.2 points higher than that of Dolby. Therefore, EVD brings absolute fever-level auditory enjoyment.
3. Can 3.EVD play DVD?
Yes, EVD can not only play DVD, but also play programs in super VCD, VCD, CD, MP3 and other formats, and the discs of ordinary people's homes will not be wasted.
Playing DVD and VCD simultaneously with EVD can improve the picture output quality by more than 30%.
4. When will 4.EVD replace DVD?
HDTV has been widely accepted by consumers. By the end of this year, the sales volume is expected to reach100000 units. EVD is an important program input source for consumers to enjoy high-definition audio-visual effects, and it will be popularized rapidly. Before the Olympic Games, at least in large and medium-sized cities, EVD will definitely completely replace DVD.
5. What is the significance of 5.EVD's independent intellectual property rights?
As DVD technology is mainly in the hands of foreign enterprises, especially Japanese enterprises, China, as the largest producer of DVD players, will give foreign enterprises a patent fee of $654.38+$200 million every year. EVD has China's independent intellectual property rights, which means that, on the one hand, China enterprises can no longer be restricted by DVD technology, which greatly saves costs; On the other hand, if foreign enterprises want to produce, they must pay royalties to China people to increase their income. This is a successful case that the country advocates intellectual property strategy, and it is also the only way to strengthen the country and enrich the people in the economic period.
6. Why does EVD attach importance to anti-piracy measures?
On the surface, piracy can make us buy cheap CDs, but in fact, it will ultimately harm our own long-term interests. EVD does the best in anti-piracy, that is, it gives the profits taken by pirates to consumers. In fact, because the anti-piracy version of EVD is very powerful, producers are willing to issue discs at relatively low prices, and gain legitimate profits through the scale advantage of low-priced genuine discs, while consumers can enjoy low-priced genuine discs at the same time.
Anti-piracy is also an important measure to enhance the national image. EVD gives consumers a chance to praise genuine products. Let's support genuine copies and the legitimate rights and interests of copyright owners.
7. Are there any other HD DVD players in the market besides EVD?
At present, the high-definition standards in Europe, America and Japan are all defined as 1920× 1080i or 1280×720p. EVD is the first disc player in the world that fully meets the high-definition standard, and it is also the only one that we can buy in shopping malls and has been tested and approved by the Ministry of Information Industry.
8. Will 8.EVD disk drives be expensive?
No, the EVD DVD player has entered mass production, and its price is equivalent to that of a well-known brand DVD.
The price of EVD is slightly more expensive than ordinary DVD, because EVD compresses and decompresses high-definition content, and its digital capacity is five times higher than that of DVD, so it uses a home appliance chip with strong computing power-equivalent to Pentium IV in a computer chip.
9. Can the contents of 9.EVD discs be guaranteed?
In order to speed up the provision of programs, Beijing Guo Fu Digital Technology Co., Ltd., the owner of EVD core technology, and Jin Dian Investment (Group) Co., Ltd., a famous real estate investment company in Beijing, established Beijing Jin Dian Global Digital Technology Co., Ltd., which, combining the advantages of technology and resources, is committed to the introduction and production of festivals, and has cooperated with China Film, Chinese Singing, Zhong Kai Culture, Li Shan Culture, Shi Fei Audio and Video, and Yingyi Culture, etc. Up to now, it has exceeded/kloc-0.
How about the after-sales service of 10 and EVD disk drives?
EVD's DVD players are all produced by famous DVD player manufacturers, and they all have their own very good after-sales service system.
Why did 1 1 and EVD bring about the film revolution?
EVD technology has been applied to digital cinema players, and the effect is exactly the same as that of advanced cinema projectors (35mm cinema projectors), but the price is only 1% of that of traditional cinema projectors, and every family's living room can be turned into a cinema.
