NVD HD disk player has a black horse appeared Evidence from optic Fair
As with the EVD, belong to our next generation HD players red light, but the former is still quite new to the industry. In early November 2006 at the International Forum on Evidence from optic storage technology, a researcher at Shanghai-ray machines and Wuhan National Laboratory for Optoelectronics HOU Li-song, Professor Xie Changsheng NVD were introduced in the latest technology and industry results, also demonstrated the first generation of commodity machines and the disc, cause for concern.
NVD acquaintance true
NVD's development back in November 2004 had already started co-sponsored by the Wuhan Optical Valley, Wuhan National Laboratory for Optoelectronics, Shanghai Institute of Optics and Fine Mechanics, CD-ROM and its application National Engineering Research Center, Tsinghua University, CD-ROM National Engineering Research Center, Wuhan Hi-tech state-owned investment company, love and more groups and other leading optical storage technology research and development of domestic institutions and businesses to initiate and implement.
NVD in appearance indistinguishable from ordinary DVD, but both the disc capacity, clarity vary greatly, NVD-sided double-layer disc capacity has been achieved 12G (capacity gradually expanded to 15G), while the single disc DVD capacity of 4.7G, double capacity of 8.5G; in clarity, NVD can achieve 1920 × 1080 high-definition playback, the DVD's resolution is 720 × 576.
The NVD and other domestic EVD HD DVD compared to the other red, the biggest highlight of the network in its download, video recorders and disc players play three functions into one, support multimedia home network to share, and support USB digital devices The Internet sharing. Users can purchase high-definition TV and video, Internet download broadcast, mobile storage and means of viewing high-definition DVD video programs. NVD download online programs through the TV, and even supports HTTP, copy reproduction and other functions, through functional expansion, NVD can also plug the camera, such as access control to monitor use of the terminal.
NVD with anti-piracy encryption technology, backward compatible with DVD, VCD, CD, DVD physical format is no longer in use, with including the disc, servo, optical, including 49 first-class technology with independent intellectual property core technology patents.
It is understood that the world's first CD last year in November NVD birth, NVD industrial research and development of prototype in July this year to complete, but at present, small-scale production of 200 units, NVD product plans to enter the market this year. NVD disk player market is expected after the price in thousand dollars down, while the price of NVD CD about 10 yuan, is the price of Blu-ray Disc 1 / 10.
New sources of paramount importance
NVD appearance, no doubt as to our own intellectual property for building the core of the HD players for the industrial system of the optical storage industry in China is of great practical significance, but in our current areas of HD DVD, and its prospects there is still great uncertainty.
NVD is the biggest problem facing the source piece of pursuing the development of EVD face the same bottlenecks. After all players are different from other consumer products, need to continue to add CD-ROM content. NVD was born early in the EVD, for example, can buy the EVD domestic program source, the basic all domestic films, even Hollywood's content, but also rare in first-line masterpiece. If not enough masterpiece listed, it is difficult to sustain their attraction, it has a large number of rich, full-chip source, directly related to the NVD and the future fate of the EVD.
