   A Seminar onthe topic BLU-RAY DISC Presented by,J.SETHU SINDHU,06121A1280, IV B.Tech,Department of Information Technology   Department of Information TechnologySREE VIDYANIKETHAN ENGINEERING COLLEGE Sree Sainath Nagar,A.Rangampet - 517 102,Chandragiri Mandal.Near Tirupati. BLU- RAY DISC 1  INTRODUCTION: Blu-ray Disc (also known as BD or  Blu-Ray ) is an optical disc storage medium designedto supersede the standard DVD format.Its main uses are for storing high-definition video, PlayStation 3 video games, and other data, with up to 25 GB per single layered, and 50 GB per dual layered disc prototypes.Although these numbers represent the standard storage for Blu-Ray drives, thespecification is open-ended, with the upper theoretical storage limit left unclear. 200 GBdiscs are available, and 100 GB discs are readable without extra equipment or modifiedfirmware. The disc has the same physical dimensions as standard DVDs and CDs.The name  Blu-ray Disc derives from the blue-violet laser used to read the disc. While astandard DVD uses a 650 nanometer red laser, Blu-ray uses a shorter wavelength, a400 nm blue-violet laser, and allows for almost ten times more data storage than a DVD.During theformat war over high-definition optical discs, Blu-ray competed with theHD DVDformat.Toshiba, the main company supporting HD DVD, ceded in February 2008, and the format war ended; in July 2009, Toshiba announced plans to put out its own Blu-ray Disc device by the end of 2009.Blu-ray Disc was developed by the Blu-ray Disc Association, a group representingmakers of consumer electronics, computer hardware, and motion pictures. As of June2009, more than 1,500 Blu-ray disc titles are available in Australia, with 2,500 in Japan,1,500 in the United Kingdom, and 2,500 in the United States and Canada. EVOLUTION OF BD: In 1997, a new technology emerged that brought digital sound and video into homes allover the world. It was called DVD, and it revolutionized the movie industry.The industry is set for yet another revolution with the introduction ofBlu-ray Discs (BD)in 2006. With their high storage capacity, Blu-ray discs can hold and play back largequantities of high-definition video and audio, as well as photos, data and other digitalcontent.2  In this it , explains how the Blu-ray disc works and how it was developed, and we'll seehow it stacks up against some other new digital video formats on the horizon.A current, single-sided, standard DVD can hold 4.7 GB (gigabytes) of information. That'sabout the size of an average two-hour, standard-definition movie with a few extrafeatures. But a high-definition movie, which has a much clearer image ,takes upabout five times more bandwidth and therefore requires a disc with about five times morestorage. As TV sets and movie studios make the move to high definition, consumers aregoing to need playback systems with a lot more storage capacity.Blu-ray is the next-generation digital video disc. It can record, store and play back high-definition video and digital audio, as well as computer data. The advantage to Blu-ray isthe sheer amount of information it can hold: ã A single-layer Blu-ray disc, which is roughly the same size as a DVD,can hold up to 27 GB of data -- that's more than two hours of high-definitionvideo or about 13 hours of standard video. ã A double-layer Blu-ray disc can store up to 50 GB, enough to holdabout 4.5 hours of high-definition video or more than 20 hours of standard3  video. And there are even plans in the works to develop a disc with twice thatamount of storage. CHARACTERISTICS: BD Key Characteristics are- Broadest Industry Support- Lifespan- Content Protection- Cost- Capacity- Robustness of Disc Broadest Industry Support History has shown that unified industry support for a particular format is most likely tolead to success. Therefore, the participation of the world's most renowned consumer electronics manufacturers and IT companies are leading in the success of the best standardfor next-generation storage: Blu-ray Disc. Blu-ray Disc is supported by leading hardwaremanufacturers across the CE and IT fields from the U.S., Europe, Japan and Korea,including Dell, HP, Hitachi, LG Electronics, Matsushita (Panasonic), Mitsubishi, Pioneer,Philips, Samsung, Sharp, Sony and Thomson/RCA. Finally, major blank mediamanufacturers including TDK are supporting the Blu-ray Disc format as the successor of DVD. This broad industry support will lead to a broad selection of Blu-ray Disc products,including home video decks, PC drives, PCs line-fitted with Blu-ray Disc drives and blank media, to be available when the format is launched in the various regions Lifespan  The Blu-ray Disc format is designed to stay relevant for at least 10 to 15 years.Its high storage capacity of 25 to 50 GB allows for the best-possible High Definitionvideo quality and satisfies even the most demanding data storage needs. As we have seenwith DVD in the past, most premium titles require two discs. This is why Blu-ray Discincorporates the additional storage space that is required for a High Definition feature filmincluding bonus bonus material in the new standard from the beginning. Formats with alesser capacity are only suitable as interim solutions, requiring them to be replaced much4
