(Blu ray disc (English Blu-ray disc, English abbreviation BD) is the next one after dvd...) The Blu ray disc (English: Blu-ray Disc, English referred to as BD), is one of the next generation DVD format after the DVD storage to store high-quality video and high capacity data. The Blu ray disc is composed of Sony and Panasonic and other enterprises "Blu ray alliance" (Blu-ray Disc Association) planning the next generation DVD specifications, and headed by Sony in 2006 began to promote related products. (Blu ray Disc founder organization consists of 13 members: DELL, HP, Hitachi, LG electronics, Matsushita electronics, MITSUBISHI, pioneer, PHILPS, Samsung, SHARP, Sony, TDK and Thomson electronic. ) The Blu ray disc is named for its wavelength 405 nm blue laser beam for reading and writing (DVD uses 650 nm wavelength red light reader, and CD uses 780 nm wavelength). Why not use Blu ray discs English name "Blue-ray", "Blue-ray Disc" is the word for popular and colloquial in Europe and America, and has explained the significance of the registered trademark application cannot constitute a license, so the Blu ray Disc Association removed English word e to complete the trademark registration. The blue DVD is to use a blue laser to read the disk, read the biggest difference with the traditional red DVD is "capacity", according to the Blu ray Disc Association, a blue DVD capacity is fifty G, which is five times the traditional DVD, so the video performance than the conventional well. Its disc is twelve cm in diameter and eight cm in diameter. It is the same as the existing CD and DVD films, so the Blu ray DVD player can still be down compatible, and the traditional DVD discs can still be played. Neither Blu ray nor HD players currently account for more than five percent of the market, and existing DVD players and recordable DVD are still mainstream. The market believes that the domestic people have watched DVD movie piracy habits, not suitable for Blu ray player, Blu ray and a blank disc as high as six, seven hundred yuan, piracy is not easy, the popularity of obstacles. DVD high resolution and DVD blue led by Toshiba in recent years has been fighting not under high resolution both in 1920*1080 resolution, but the storage capacity, the blue DVD up to 50GB, and the high resolution DVD is only 30GB, but in terms of price, price of blue DVD NT $20 thousand to 80 thousand yuan, and HD DVD is 6 thousand to 20 thousand. Due to the high cost of Blu ray equipment components, the premium is high, the light is the two expenditures accounted for the total cost of more than 55%, and the main monopoly in Japanese hands, with high barriers to entry, the price of blue equipment the rate of decline is slower than the market forecast of fear. Blu ray DVD contains two technologies, namely Blu-ray DVD and HD DVD., which all use blue light LD as the light source. These two blue light formats are incompatible, but they can all be compatible with the current DVD format. In February 19, 2008, with the HD DVD leader Toshiba announced that it would end all HD DVD business at the end of March, the next generation DVD format continued for many years to formally end the dispute, and ultimately led by Sony's Blu ray. Have separation of the outcome, the nation's largest DVD distributor Warner Brothers announced after the release of the Movie DVD, will be released only made by Sony's Blu ray format, as currently has four American Film Co choose the Blu ray format, future DVD specification is almost certain to a blue led. The nation's largest DVD disc user, Warner Bros., retail giant WAL-MART, has announced support for Blu ray DV-D, and opportunities for Blu ray DVD discs, compact disc players and players will rise. Taiwan two Blu ray machine OEM LITE-ON electric and Guangming; Blu ray disc chip supplier MediaTek, Ling Yangqi under sunext technology and Blu ray discs; Dachang central Ritek and electronics industry in Taiwan, will be the biggest winner. DVD manufacturers said that the standard is not unified and the price is too high, the blue DVD popularity rate is slow, if can with the Blu ray Disc "domination", the industry to expand production capacity and lower prices, appears to accelerate the killer application, Blu ray DVD business opportunities will be considerable, and by next year, the market will grow substantially. Sunext technology MediaTek and Sunplus investment, is one of the earliest investment company IC design development the next generation DVD chip, Wang Yang made PHILPS semiconductor optical storage products and technology licensing, including Blu ray; MediaTek adopt independent development strategy, with MediaTek, Sunplus chip shipments will continue. To break the monopoly by blue chip market situation. MediaTek's blue chip read-only CD early shipment, and won the LITE-ON electric, gmy by next year the launch of Blu ray DVD player chip. However, MediaTek also believes that although Blu ray chips have started shipping, the market has just started and has not contributed much to this year's operation. Many vendors who originally chose the HD DVD camp are heading for the Blu ray camp. CD industry Ritek also bet on HD DVD and Blu ray two specifications, last year into an alliance with Toshiba HD DVD market, 16 foreign production HD DVD consider the outgoing Toshiba, Ritek and Toshiba cooperation will be tested, but Ritek's Blu ray DVD upcoming production, the market also has blue harvest. In the beginning the Blu ray format in HD DVD optimistic, less, but the central chairman Weng obviously believes that even if the Blu ray format finalized, blue premium is too high, may affect the investment willingness of disc manufacturers. Weng Mingxian said that the company has over 30 Blu ray intellectual property rights, and that the IP manufacturers only want to collect the royalty and not put it into production. The blue light DVD is still in the training stage. "The business opportunities in these two years are still quite limited.". Taiwan manufacturers have not yet put Blu ray player and Blu ray recorder production home, LITE-ON electric and Guangming is currently focused on the Blu ray disc production by computer. Blu ray disc products widely prescribed is not yet listed, LITE-ON electric read-only Blu ray DVD, Blu ray and DVD burner shipments estimated at thousands of spectra.
