Blu-ray Disc

  1. 1. Anu G
  2. 2. 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.
  3. 3. 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.
  4. 4. Evolution <ul><li>VHS: analog DVD: digital BD: high-definition </li></ul><ul><li>Enables recording, rewriting, and playback of high-definition video </li></ul><ul><li>Capable of storing information that the DVD and CD are not capable of holding </li></ul>
  5. 5. The Name The Blu-ray name is a combination of &quot;blue,&quot; for the color of the laser that is used, and &quot;ray,&quot; for optical ray. The &quot;e&quot; in &quot;blue&quot; 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.

  11. 11. Formats Unlike DVDs and CDs, which started with read-only formats and only later added recordable and re-writable formats, Blu-ray is initially designed in several different formats: BD-ROM (read-only) - for pre-recorded content BD-R (recordable) - for PC data storage BD-RW (rewritable) - for PC data storage BD-RE (rewritable) - for HDTV recording Java Software Support <ul><li>Java is used to implement the interactive menus on BD </li></ul><ul><li>The Java software on BD is called BD-J </li></ul>
