What's the difference between DVD and EVD?
Due to the advanced compression method, EVD provides higher image quality than DVD-Video on the same optical disc.
EVD(Enhanced Versatile Disk) is an enhanced multimedia optical disc system, commonly known as "new generation high-density digital laser disc system", which is an upgraded product of DVD. The resolution of EVD products is five times that of DVD. In terms of sound effects, high fidelity and surround sound are realized at the same time for the first time in the world. At present, an EVD DVD can store about 1 10 minutes of audio and video programs. Experts pointed out that EVD perfectly combined shocking sound effects with bright image quality, and realized the storage and playback of high-definition digital programs based on CDs for the first time in the world, bringing DVD players in the high-definition era to the people of China. [Edit this paragraph ]EVD analysis Compared with super VCD and DVD, EVD has obvious technical advantages. Product performance indicators show that the difference between EVD and DVD is firstly high definition, and the pixel of EVD is nearly five times higher than that of DVD, so it can receive digital TV programs. It has a unique "erasable function", which can directly record programs and directly carve the broadcast programs into CDs; It is completely compatible with computers. By connecting home appliances with computers, an information network within the family can be established. According to the professional's prediction, the industrial scale of EVD will reach the annual production capacity of/kloc-0.0 million DVD players and 200 million optical discs next year, and the supporting production capacity of related equipment will exceed/kloc-0.0 million.
EVD is made in China in the true sense: it has independent intellectual property rights, grasps the core technology, and controls the right to formulate and modify standards. EVD is a powerful and widely used new consumer electronic product, which integrates the player for playing high-definition digital programs, hi-fi with surround sound effect, karaoke with super capacity, video recorder, games, set-top boxes, videophones, Internet access and computers that can meet the needs of ordinary families. In addition, it can also be used as test and demonstration equipment for TV production and sales.
EVD supports the storage and playback of high-definition TV programs, which has obvious technical advantages over DVD: it has network browsing function and supports automobile traffic navigation; Support home information network platform and game machine functions; Established the leading position of audio compression in the world; A self-established standard was established, which brought DVD players in the high-definition era to Chinese people and set an example for domestic related enterprises to expand their living space.
From the patents published by EVD technology, it is mainly the optimization method of audio and video filtering transformation and coding and decoding, which can improve the quality of audio images and increase the data compression ratio. In addition, there is a method of "dynamically superimposing subtitles on digital video" inherited from SVCD, which can display subtitles in 256 colors. Includes five softwares, namely DVD-EVD conversion software, AC3-EAC conversion software, OGT production system, EVD digital video disc production system and VCD/DVD/EVD player. "EVD" is a digital optical disc system for which China people have independent intellectual property rights, and it is also the national standard in the field of digital optical discs in China. The technical specification of EVD system has been submitted to the International Electrotechnical Organization and the International Organization for Standardization, and it is expected to become an international standard. In order to provide users with clearer programs, the EVD system nearly doubled the speed of the code stream on the basis of the original DVD technology. [Edit this paragraph] Is ]EVD's technology advanced or outdated? A Japanese newspaper in Beijing once published a report entitled "Insider Reveals: EVD is just an improved version of DVD four years ago". It is mentioned in the article that HDV enterprises and Suning executives exclusively exposed the "shortcomings" of EVD to this newspaper, which mentioned that EVD is only an improved version of DVD and adopted it. The report also mentioned that the HDV chip adopts the advanced technology at the same level as Microsoft's related technology, which can be compatible with EVD, but the EVD machine can't watch HDV discs.
In addition, the company's top management also mentioned that EVD has now formed an alliance with Gome Audio and Video, and its real intention is to promote EVD discs.
At present, every time other home appliance chain enterprises sell an EVD DVD player, they are actually helping Gome sell hundreds of EVD DVD players. So what is the concept of EVD? Is it worth buying by the general public? With these questions, our reporter interviewed Liu Jingli of Beijing Guo Fu Company with EVD patent. Can EVD unify the rivers and lakes?
According to Liu Jingli of Guo Fu Company, many indicators of EVD on the market are better than DVD. . Ordinary consumers don't need to use any instruments to detect. They can clearly distinguish the difference between two kinds of CDs played by players and TV with the naked eye for 5 seconds. EVD is not only better than DVD in definition. EVD has also changed a lot in audio. By then, we will be able to have a high-density digital laser video disc system with much higher picture quality and clearer sound than DVD.
In addition, EVD machines are also easily compatible with DVD and VCD discs. The so-called EVD film source problem rumored by the outside world is actually a hype of stealing the concept.
However, the release of EVD standard did not make the industry happy as expected. An executive of an electronic appliance chain in Beijing pointed out, "This is only the technical standard of EVD, and it does not represent the technical standard of high-definition disc players in the future. EVD technical standards need to be fully promoted and applied in the domestic market, and at the same time, they also face competition from many similar technologies. "
However, the price of EVD is relatively high, and only high-definition digital TV can achieve the best effect. For the above reasons, at present, nine mainstream DVD manufacturers have different steps in promoting EVD products. In the domestic market, only Shinco and SVA will push EVD to the market, and the rest manufacturers will stay put. What is the EVD standard?
EVD calls it a new generation of high-density digital laser video disc system. Compared with DVD and super VCD, EVD has obvious technical advantages, which fills the gap in the storage and playback of high-definition programs in China. At the end of 20001,EVD passed the technical appraisal of the Ministry of Information Industry, and the technical standard was also developed by Guo Fu Electronics.
EVD standard is a high-definition industry standard for optical discs and players formulated by the major consumer electronics manufacturers' alliance in China, and it has many independent intellectual property rights. The members of the alliance include dozens of enterprises and scientific and technological institutions such as Xinke, Amoi and the Ministry of Information Industry.
Every time a DVD manufacturer in China sells a DVD in China, it has to pay a patent fee of more than ten yuan to the "6C Alliance" which owns DVD intellectual property rights. If exported, the patent fee will exceed $20. The person in charge of Beijing Guo Fu Digital Technology Co., Ltd. said in an interview last year: "In order to prevent the next generation DVD player from repeating the mistakes of the domestic DVD player industry, and thus grasp the leading role in the development of China's HD industry, it is our original intention to develop EVD." [Edit this paragraph ]EVD technical features In terms of video, the system not only realizes standard definition, but also realizes eight different video quality from VCD quality to high definition, fully supports various use requirements and use environments including high-definition digital TV, and can be directly used as test equipment and home entertainment equipment in the production of high-definition digital TV.
In terms of audio, the system adopts EAC audio compression technology with independent intellectual property rights, which not only fully supports mono, dual channels and 5. 1 channel, but also has better performance than Dolby AC-3, which is usually used in DVD players and charges a high license fee.
In terms of subtitles, the system inherits and develops the research results of Super VCD, realizes 256-color floating subtitles and supports transparent colors. The display quality and flexibility of subtitles are far superior to DVD subtitles.
In addition, more importantly, EVD obtained 22 patents, developed 5 sets of software, and was tested by a third party. Compared with super VCD and DVD system, EVD has obvious technical advantages, which fills the gap in the storage and playback of high-definition programs in China, which is a pioneering achievement in China. Among them, the audio compression algorithm (EAC) with independent intellectual property rights is adopted to generate better audio than Dolby AC-3 at the same bit rate, reaching the advanced level in the international audio compression field. [Edit this paragraph] How many problems need to be solved when ]EVD replaces DVD? "If there is not enough market share, even the best standards will not succeed." Ni Guangnan, an academician of China Academy of Engineering, said at a forum.
In China, the disc player products range from VCD, SVCD and DVD to HDV and EVD, which can be described as "I will appear after you sing". VCD and SVCD are not working, and the general trend is gone; As a relatively mature product, DVD is still the mainstream of the disk drive market, monopolizing the whole market. On February 23, 2005, EVD, HDV and HVD, which were once heated up, were suddenly released by the Ministry of Information Industry, and the dust settled. EVD (full name: high-density digital laser video disc system) is officially listed as the recommended standard of the national electronics industry and has become a well-deserved winner to replace the DVD era.
According to the relevant person in charge of Guo Fu Digital Company, which specializes in developing EVD technology, "EVD has become a national recommended standard, and we will vigorously promote the market and completely replace DVD products in the next step. At the same time, technology update is also an important measure for us to cope with foreign technology competition. "
EVD has fallen again and again, and gradually slipped to the market price.
It is understood that there is only one new EVD-8700 EVD in the domestic market at present. It was first listed in June 5438+last year 10. At that time, consumers didn't know much about the new generation of high-density laser discs, and the price of EVD single set 1998 yuan far exceeded people's psychological price. Therefore, when the EVD player first appeared in stores, it didn't get a response from the market.
Just as many home appliance stores in China gradually lost confidence in EVD and even pulled it out of stores, in June last year, Dazhong Electric City built the first "EVD HD Experience Hall" in China in its flagship store Zhongta Store. At the same time, we negotiated with Guo Fu Digital, the developer of EVD technology, and Shinco, the main manufacturer of EVD players, and the three companies reduced the market price of EVD players. The price of EVD players dropped from 1.998 yuan in June of the same year to 1.698 yuan. Since then, its price has dropped sharply several times. Until February 23 this year, EVD was promoted to the national recommended standard, and the market of EVD gradually opened, and consumers began to pay attention.
At present, the sales of EVD have increased significantly. Recently, the reporter learned in Dazhong Electric Appliance City that the national unified promotion price of the new EVD-8700 player is 998 yuan, which is the most stable price stage since EVD appeared in the home appliance market in Beijing for more than a year, with a drop of 55% compared with a year ago. According to the sales staff of Dazhong Electric, the daily sales volume of EVD is now three or four more than before, and more and more consumers come to inquire about EVD. According to relevant sources in stores, some TV manufacturers have recently signed contracts with Dazhong to use EVD to promote and demonstrate high-definition and flat-panel TVs in various stores.
According to the staff in the store, although the sales potential of EVD has increased slightly, DVD players still occupy the vast majority of the market. The main reason is that the picture effect of DVD and EVD is not obvious on ordinary TV. Only by playing on HDTV and flat-panel TV can we show the advantages of EVD more clearly and enjoy the resolution of EVD. At present, these high-definition digital products cost 10 thousand yuan. For ordinary people, you won't replace a high-definition digital TV set with nearly 10,000 yuan just because it costs less than 1000 yuan. In addition, there are few EVD discs on the market at present, and there are few ways to buy them. Compared with the DVD that can be bought everywhere, consumers prefer to choose a convenient and cheap DVD.
DVD dilemma gives birth to EVD technology
At present, China has developed into the largest DVD production base in the world, seizing the market, but the problem of DVD patent fees has been puzzling DVD enterprises in China. The relevant person in charge of the China CD Industry Promotion Committee told the reporter that as the core technologies and standards have been in the hands of foreign developers for a long time, multinational companies frequently create patent barriers by using the sharp edge of intellectual property protection. According to incomplete statistics, China's DVD manufacturers pay nearly 654.38 billion yuan in patent fees to foreign enterprises every year. Every DVD player in China must pay a patent fee of $4 to organization 6C and $5 to organization 3C. At present, the average selling price of DVD products exported from China is generally below 100 USD, and the profit is less than 5%. It can be said that the low price and high cost make it difficult for DVD manufacturers in China.
No product can dominate the market for a long time, and DVD players are no exception. Although it is a key transformation product from fuzzy technology to digital technology video equipment, once advanced technology is mastered by many enterprises, it is no longer a means to compete for market share. At present, DVD sales in the market are increasing, while the total sales are decreasing, which is a dangerous market signal. Once the price war becomes the main means of enterprise competition, it is bound to be the survival of the fittest of enterprises and technologies and the elimination of the market.
Therefore, the DVD dilemma gave birth to EVD technology, and the introduction of EVD is considered as the "golden key" to unlock the DVD patent fees in China. The success of EVD research and development is the result of China enterprises implementing independent intellectual property strategy and standard strategy. It not only owns independent intellectual property rights, but also controls the formulation and revision of standards, which is helpful for domestic DVD players to enhance their core competitiveness and change their passive state in intellectual property rights.
The industry believes that with the increasing demand for high-definition pictures, the prospect of EVD will be very broad. In addition, the 2008 Olympic Games will increase the live broadcast of HDTV, which will inevitably promote the popularity of HD players represented by EVD.
EVD must pass three levels.
Although the EVD market has improved at present, there are still three obstacles to achieve greater development in the future. First of all, it is the pressure from the shortage of film sources in EVD DVD players. Up to now, only a few dozen EVD discs can be seen in the market, which is far from the target of 300 discs by the end of 2004 promised by EVD. Although EVD DVD player can be compatible with almost all discs, there is no special EVD disc, which simply does not reflect the high-quality film effect promised by EVD, and the user's investment in EVD will lose value. When the market prospect of EVD is uncertain, most optical disc manufacturers only hold a conservative and wait-and-see attitude towards the mass production of EVD optical discs.
In July 2004, the EVD optical disc market seemed to be a precursor to prosperity. Guo Fu Science and Technology Co., Ltd. formally signed a contract with Jin Dian Group to set up Jin Dian Global Digital Technology Co., Ltd., which produces EVD special discs. It plans to invest 654.38+0 billion yuan and introduce large films in three years to completely solve the source problem of EVD films. However, when the reporter recently walked into the video store on the street in Beijing, the number of EVD CDs was very small, and many consumers still knew nothing about EVD. Just as the supply of DVD was hard to find when it was first listed, EVD also suffered the same embarrassment.
Secondly, the high price of supporting high-definition digital TV has become the bottleneck of EVD popularization. High-quality audio and video provided by EVD DVD players also need high-definition digital TV to restore. EVD's high demand for TV sets also raises the threshold for enjoying EVD movies. There is no difference between EVD movies played on ordinary TV sets and traditional DVD discs. Buying a high-definition digital TV is more expensive than ordinary TV 1000 yuan. This price difference has greatly exceeded the budget of ordinary consumers and has become an obstacle to the popularization of EVD.
Finally, the competition from other technologies makes the future of EVD more confusing. For example, the emergence of HDV products, originally HDV and EVD came from the same door, and the company that developed HDV was once one of the shareholders of EVD technology development. Although Kaicheng HD, which develops HDV technology, has repeatedly stressed that HDV is different from EVD, its technical details are difficult for laymen to understand. After all, both EVD and HDV pursue the development direction of the integration of home appliances and IT, and the goal of working towards high-definition, large-capacity, intelligent and information-based home appliances is the same.
According to industry insiders, although EVD has been one step ahead in the dispute over the standard of high-definition DVD players, HDV and HVD standards can still compete freely with it because it is a recommended standard rather than a mandatory national standard. In addition, the extent to which the adoption of standards can stimulate sales and help EVD regain the market divided by HDV and HVD remains to be tested.
It is also said that EVD is not a revolutionary leap, because it only makes some technical improvements on the basis of the original DVD player. If EVD technology had come out two years earlier, its significance would have been completely different, and it could have become a bargaining chip for exchanging technology patents with 6C Alliance, which has mastered the core technology of DVD. But now foreign DVD technology has been updated several times, and the "Blu-ray technology" announced by the new 9C Alliance can be mass-produced in three years at most, which will be a huge impact on the traditional DVD industry. In addition, under the threat of new technologies such as "blue-purple technology" introduced by Toshiba and NEC, it is really worrying how big the living space of EVD is.
In fact, regardless of the market prospect of EVD, domestic enterprise alliance * * * has great courage to challenge foreign standards by developing its own standards, and also found that the bottleneck restricting its development lies in not mastering the core technology and actively exploring solutions through various ways, which shows that China enterprises have gradually matured from blindly following international trends and price wars. However, the development of these new technologies depends on the guidance and support of the government's macro-policies, and it has yet to be tested by the market and consumers.
A person in charge of the Science and Technology Department of the Ministry of Information Industry once said: "China has a huge market, which is enough to support the development of our EVD industry." [Edit this paragraph ]EVD standards are chaotic, film sources are in short supply, prices are high, and royalties are expensive. Under such a problem, can the domestic EVD standard published on July 8 become a national standard after the expiration of one month's publicity, and then sprint to the international standard? This is still a mystery.
As one of the many alternative products of DVD, EVD standard, which was formulated by China's major consumer electronics manufacturers alliance, was the first to win the official title. However, analysts here said that the EVD standard is only an industry standard recommended by the "New Generation High-density Digital Video Disc System Standard" working group established four years ago and the Electronic Standards Association, and the Ministry of Information Industry is only in the stage of soliciting opinions from all parties. Real industry standards are not expected to be released until the testing of standards such as HVD and HDV is completed. The optimistic forecast is not less than 1 year.
Analysts further pointed out that if a standard is to be adopted by people, it should be open, with independent core technology, industrialized and without unreasonable patent fees, so as to attract the participation of large global companies.
"Starting from the idea of avoiding paying unreasonable royalties, it is a positive move to formulate domestic EVD standards, but if the principles of advanced, independent, open and compatible are not followed, it will be difficult for EVD standards to rank among the international standards. WAPI is a lesson from the past. "
Advance in chaos
Since the establishment of 1999, it was publicized by the Ministry of Information Industry in July this year. The EVD alliance, which consists of nine home appliance companies, such as Shinco, SVA, Skyworth, Changhong, Amoi, Malata, BBK, Xianke and Xoceco, can be said to have been crawling forward, and the progress is very slow-the sales situation of EVD disk drives after listing was not optimistic until the beginning of this year. In addition to the high price of EVD DVD players, the lack of film sources is also a major constraint.
In terms of disk drives, EVD alliance members include Xinke, SVA, Amoi and so on. All related products have been launched, among which Shinco Group has reduced the product price from 1.998 yuan to 1.398 yuan, but compared with DVD players, its price is still not competitive.
The problem of film source is equally prominent. According to the newspaper, Jin Dian Group, a domestic real estate developer, has invested 200 million yuan with Guo Fu Digital Technology Company, the sole entity of EVD Alliance, and signed a contract to establish Beijing Jin Dian Global Digital Technology Co., Ltd., which specializes in EVD DVD production. It is planned to invest 1 100 million yuan in three years to start introducing content. However, there are many doubts in the industry about whether the company can meet the supply of film sources in the national market.
What is more difficult is that EVD is not the only country that has the strength to compete for the international standard of the next generation of digital disc recorders. Whether it is the Blu-ray DVD camp composed of Panasonic, Sony, Philips and other manufacturers, the DVD forum camp supported by Toshiba, NEC and other manufacturers, or the red light camp based on HVD and HDV, they have been fighting for international standards before.
In China, apart from the EVD alliance, HDV is built by Beijing Kaicheng HD Electronic Technology Co., Ltd., and HVD is promoted by the HVD alliance composed of Skyworth, Changhong, TCL, Malata, etc. 19 companies, among which Skyworth, Changhong and Malata are also members of the EVD alliance. Interestingly, although EVD, HVD, HDV and other standards belong to the red light camp, in order to compete for the right to speak of industry standards, the three companies sometimes fight with each other.
For example, although they all belong to the anti-Blu-ray camp, as soon as the HVD Alliance entered the market, it took the lead in launching the HVD chip designed and provided by Chen Jing Semiconductor Co., Ltd. in Silicon Valley, USA. It is understood that the intellectual property of this HVD chip belongs to the Chinese side, because Chen Jing was controlled by Shanghai Shentong Technology and Shanghai Chemical Industry Group as early as 1999. In addition, the market performance of HVD products has been better than that of EVD since they went on the market.
In view of the fact that the Blu-ray DVD camp indicated that it would enter the China market in 2007, some insiders pointed out that before Blu-ray DVD products were popularized in China, domestic alliances such as EVD, HVD and HDV should compete with each other for compatibility. "A variety of formats in the market exist at the same time and are incompatible with each other, which will inevitably lead to confusion when consumers buy. As a result, no one can do much. "
The myth of kingship
It is understood that the EVD standard not only refers to the international standards ISO 138 18(MPEG-2) and ISO 16448, but also has independent intellectual property rights in many aspects such as sound, navigation system (function expansion) and copyright protection technology, but the core chip still comes from overseas.
According to sources, Guo Fu Digital, the main member of EVD, had planned to acquire about 3% of the shares of One2 Company with VP5 and VP6 video compression technologies for 654.38+0 million US dollars, and planned to appoint general manager Hao Jie as a member of its board of directors. However, due to the delay in the approval of the relevant domestic administrative departments, we had to obtain the patent right of the above technology at a price of 50 thousand US dollars. This amount of equity is considered to be sufficient to ensure that Guo Fu has the right to know about the major decisions made by its board of directors.
For another American LSI logic company with EVD chips, Guo Fu established an EVD chip joint laboratory with it through negotiations, and handed over the OEM rights of the chips to the company. As a price, Guo Fu was exempted from the patent fees that should have been paid.
"Exemption belongs to exemption, but the patent fee that EVD has to pay is not less than that of DVD, because EVD players have to pay patent fees to foreign DVD patent organizations such as 3C and 6C for the backward compatibility of DVD discs. The same is true for HDV and HVD. " The source said.
Under the pressure of patent fees and price wars, nearly 30 DVD factories have stopped production or closed down in Baoan District, Shenzhen, where DVD production enterprises gather in the past six months. Some big-name DVD companies trying to enter the international market have quietly stopped and turned to high-end products such as mobile DVD, EVD and LCD TV. However, the confusion of EVD market in terms of standards and market size makes these enterprises in a dilemma.
After realizing the difficulties in the implementation of the standards, Ms. Tian Yujing, a senior engineer at the Institute of Television Electroacoustics of the Ministry of Information Industry, said that EVD standards should be recommended instead of mandatory national standards, and HDV and HVD standards can still compete freely with EVD even after the publicity period. "If the national mandatory standards are declared, the original DVD player will not be sold in the market, which will bring great shock to the whole industry and is not conducive to the smooth transition of the industry."
Unlike WAPI, which is a mandatory national standard, EVD has aroused the vigilance of the US-China Economic and Security Review Commission since its release, but it is not mandatory, so it has caused less backlash. The Committee even thinks that it is very unlikely that the three HD standards, EVD, HVD and HDV, will become international standards.
However, after WAPI was shelved, the pace of formulating independent intellectual property standards in China has not stopped. In addition to EVD standards, independent intellectual property standards such as TD-SCDMA, AVS, IGRS and DHWG have exposed the tip of the iceberg, and there are more China standards brewing and sneaking below the sea level, which will soon surface. [Edit this paragraph] EVD Chronicle 1999, Shinco, Shanghai Radio and Television and other enterprises jointly established EVD Technology Development Company-Beijing Guo Fu Digital Technology Co., Ltd.
In June 2003, 165438+ 10, nine manufacturers, including Shanghai Radio and Television, Shinco, Amoi and Changhong, jointly established the "China EVD Alliance", and launched the first EVD disk drive on New Year's Day in 2004. The EVD player with independent intellectual property rights in China was launched in June 165438+ 10/8.
In July 2004, Jin Dian Investment Group Co., Ltd. and Beijing Guo Fu Digital Technology Co., Ltd. jointly invested and established Jin Dian Global Digital Technology Co., Ltd., which further accelerated the industrialization process of EVD.
On February 23rd, 2005, the Ministry of Information Industry of China issued the Notice on Approving to Publish the Technical Specification of High-density Digital Laser Disc System and the Electronic Industry Standard, and determined EVD as the "Recommended Standard of Electronic Industry".
On July 2nd, 2005, Beijing Guo Fu Digital Technology Co., Ltd., the main promoter of EVD standard, and stmicroelectronics (ST), the chip manufacturer, announced at the China International Consumer Electronics Show held in Qingdao that H.264 video coding technology would be adopted to develop the next generation EVD standard.
On September 8, 2005, Beijing Guo Fu Digital Technology Co., Ltd., the main promoter of EVD standard, will cooperate with NMEI (New Media Enterprise Company) to develop the next generation EVD standard based on VMD optical disc technology.
On September 26th, 2005, the National Working Group on Digital Audio and Video Coding and Decoding Technology (referred to as AVS standard working group), Institute of Computer Science of Chinese Academy of Sciences and Beijing Guo Fu Digital, a new generation of high-density digital video disc system standard working group (referred to as EVD standard working group), signed a cooperation agreement to realize the complementarity of standards and technologies, and will develop the next generation EVD standard based on AVS video coding.
On June 29th, 2005, 10, Beijing Shi Sheng Longtian Company launched the EVD player for PC, which is an informal test version. Up to now (65438+February 2005 10), Shi Shenglongtian Company has not released the official version of EVD player.
On June 29th, 2005, 165438+ Beijing Guo Fu Digital Technology Co., Ltd., one of the major manufacturers of EVD standard, signed an equity exchange agreement with NMEI (New Media Enterprise Company), which caused an uproar. Topics revolve around: whether the China standard was bought by Britain, whether Guo Fu Digital sold the national standard for funds, whether the VMD CD developed by NMEI can make up for the shortcomings of the current EVD technology, whether the cooperative relationship between Jin Dian Universal and Guo Fu Digital has broken down, and whether the insider of the equity transaction is personal income. The above topics have not yet been finalized.
On June 5438+February 1 1 day, 2005, Jin Dian Universal announced to upgrade the EVD standard, and the newly released EVD high-definition movies in the future will adopt the brand-new AACS (Advanced Access Content System) encryption standard. This new encryption standard can better protect CD contents from piracy. Jin Dian Universal adopted AACS encryption standard because Guo Fu Digital, one of the leading manufacturers of EVD standard, also authorized Beijing Shi Sheng Longtian Company to develop special PC playback software for EVD, which made Zhang Baoquan, president of Beijing Jin Dian Universal, think that this would make the original anti-piracy technology of EVD be cracked artificially or lost. Fan, vice president of Shinco Electronics, made it clear at the press conference of Global 65438+February 1 that he supported the strategy of adopting AACS encryption algorithm around the world. However, according to foreign news, the AACS encryption standard is not expected to be completed until June 5438+ 10, 2006, which means that there is no formal AACS encryption standard used in any products at this stage.
