Into the design phase of what DVD changed C-HD
First, changed the patent fee payment. The reason why China tried to international DVD Forum powerful requirements to apply for China's own HD DVD, mainly in order to change China drive industry pay higher royalties, while China still more advanced optical technologies in the international arena can. In the future the Blu-ray format will have on BD, HD DVD and DVD three C-HD. China a independent property right of the CD format. China electronics technology group Corporation third Institute senior engineer Tian Yu Jing told reporters: "C-HD DVD from the physical format to use for audio and video coding and navigation systems are not the same with HD DVD so that you can make patent costs significantly. "Deputy Director of the research center of Tsinghua University CD Luda in accept IT168 reporters also mentioned:" the current DVD in physical format C-HD change the modulation and demodulation codes, but with AVS audio and video encoding, and the navigation system will make the appropriate improvements will be made in line with China's own navigation system. "Luda said, after major patent costs mainly to the technical units, as well as Union pay, which is part of China's independent intellectual property rights, future patent costs will be significantly reduced, but it's sure. Tian Yu-ching to journalist revealed that, due to the overall framework C-HD DVD or DVD based on Toshiba's HD, so on the basis of, or to pay part of patent costs of Toshiba, but it would be better than direct production costs of HD DVD a much smaller. At present, the overall C-HD DVD is patent non-how much you want to collect, to reduce the amplitude of the concrete, it is still not finalized.
C-HD HD DVD or DVD with a lot of links to different
Secondly, the protection of the safety C-HD DVD will be on the existing HD DVD. At present, China is and AACS Union discuss how to improve for the DVD encryption C-HD. Thus, in the protection, China remains and AACS together, this means that AACS also will charge the appropriate number of the patent fee, currently underway. Relevant industry sources, for China on DVD in NDA C-HD definitely be a great improvement. The industry also says that BD and HD DVD and DVD with AACS C-HD protection agreement can be repaired, piracy will be stronger than the previous control. When talking about BD and HD DVD crack, luda told reporters: "Although the BD and HD DVD has been solved, but it's just a seiryu, this approach is not possible to copy entire disc out, just as you can see information on the computer, it is impossible to make the disc, i.e. to disc piracy appeared the odds of the form will be very small. ”
Third, the issue of pieces of original C-HD DVD is currently not very distinct. This reporter has learned that the DVD is China C-HD independent intellectual property rights of AVS audio and video encoding format, this depends on whether a piece of original AVS coding movie. In mainland China are special, we take copyright control mode for film distribution, copyright control Department decided to introduce the film, so it is possible to have AVS encoded movies, how many film is going to the movies copyright management Department, luda said so. In fact, for the coding, the film is not very important, the film's main focus to host media protection measures. "DVD also has international forum organization 8 large ' in Hollywood, so what protection measures C-HD DVD, they were already recognized, so the ones limitations should not just look at domestic film distribution companies to think of how much money can bring in what movie" Tin-Yu Jing told reporters.
The prospect of internationalization C-HD DVD
C-HD DVD exported to Europe, there is no way to play when the disc region code, this is the Chinese version of the HD DVD international exports the most headache problem road. But the reason or reasons to stick mainly C-HD DVD is international recognition, the DVD Forum can be integrated into international product format. In the future there will be the international disc formats DVD-a, C-HD it actually facilitates C-HD DVD into the international market. Get VCD, this is a unique product in China, Viet Nam, nowadays in and some South-East Asia region continues to use VCD format. But in fact there are individual countries and regions and China discussed matters relating to the introduction of Chinese format.
C-HD DVD but also bringing in, going out of the process
Therefore, the Chinese have international recognition and own HD DVD format in order to achieve international status. Just like in reference to national standards, one of the industry's answer: "we are not eager to push the C-HD DVD, first national standard is ripe, and so allow us to use. In fact, as long as the market is big enough to cover
Cover a wide enough, people will have with AVS DVD encoded format by other regions C-HD and national recognition. ”Many uncertain factors make industrialization will take some time
Currently C-HD DVD only just finished a technical specification that is approved by international DVD Forum to begin this specification, the Islands are still far from production. C-HD DVD there are many factors that have not been finalized, therefore now turn to the actual product or earlier.
It is noted that the current is still in the design stage may be about to change DVD C-HD past HD DVD use the LOGO. This alone shows C-HD DVD industrialization had not yet begun.
Formation of industrialization is still immature, it takes some time
Since DVD for C-HD PRC specification, China has its own specific area code, this also makes the other two districts (HD DVD has three regions, China, Russia and other regions) for HD DVD disc cannot be played in a DVD machine C-HD. This is a piece of original previous headaches. At the same time also brings a number of uncertainty factors — if production compatible, then the part belonging to HD DVD patents fees must pay, this greatly increased manufacturing costs, the average consumer is difficult to accept. So, what is the future look at other areas of the disc is compatible with the opportunity to do, do not appear in the market, in what position and prices in the market, decoding machine will act as what role?
As mentioned above, in cooperation with the AACS encryption work, there are no end of specific cooperation programmes as well as a detailed description of improvement. You know, if the work is finalized, the DVD is a C-HD empty shell, it is not going to get any content publishers support.
While in the process of industrialization has played a decisive role in the enterprise, the enthusiasm for this thing and not very high. Shenzhen love rope good industrial co., Ltd. of thoughtful of Temasek's Yu, Deputy General Manager, said that for this thing, we are watching, whether to cooperative production, to look after going products. New section of the CCA press spokesman Vincent also revealed that recent new section is concerned with this issue, we must first understand what C-HD DVD again later. Do not know the drive manufacturers really is to vigorously pursue EVD2, or we go on the road of EVD too hard, most manufacturers are in a wait-and-see attitude, not until the last moment is never easy.
For schedules, Tian Yu-ching to journalist admits, many are still not perfect, but into the overall framework of the design phase, expected before the end of the year will have a prototype. This shows that no unexpected events occur, this year we can see C-HD DVD of flesh, but when the market a bit in this description: now even have a prototype or description you can have the scale of production, so now about C-HD DVD overall industrialization or earlier.
