Blu-ray Disc Blu-ray Disc Presentation Transcript

  • Anu G
  • Blu-ray Disc was developed by the Blu-ray Disc Association, a group of companies representing consumer electronics, computer hardware, and motion picture production. The standard is covered by several patents belonging to different companies. Blu-ray Disc (Blu-ray or BD) is an optical disc storage media format. Its main uses are high-definition video and data storage.
  • 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-definition video or about 13 hours of standard video. A double-layer Blu-ray disc can store up to 50 GB, enough to hold about 4.5 hours of high-definition video or more than 20 hours of standard video.
  • Evolution
    • VHS: analog DVD: digital BD: high-definition
    • Enables recording, rewriting, and playback of high-definition video
    • Capable of storing information that the DVD and CD are not capable of holding
  • The Name The Blu-ray name is a combination of "blue," for the color of the laser that is used, and "ray," for optical ray. The "e" in "blue" was purposefully left off. The name Blu-ray Disc is derived from the blue-violet laser used to read and write this type of disc.
