  1. Blu-ray Technology • What is Blu-ray? • Difference between DVD and Blu-ray • Will the technology last? Matthew Werner Group 7

  2. Background Info • In 1997, DVDs revolutionized the movie industry • Audio and video quality was far superior to the previous VHS • Now, the Blu-ray technology is having the same effect on DVDs as they did on VHS

  3. What is Blu-ray? • Next generation optical disc • Developed to enable recording, rewriting, and playback of high-definition video

  4. How it works • While current optical disc technologies such as DVD rely on a red laser to read and write data, the new format uses a blue-violet laser instead, hence it’s name Blu-ray • The discs come in single or double layer. Single layer can hold 25GB and double can hold 50GB of data compared to DVDs holding 4.7GB of data

  5. How it works • The benefit of using a blue-violet laser is that it has a shorter wavelength than a red laser, which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it's possible to fit more data on the disc even though it's the same size as a CD/DVD.

  6. Blu-ray vs. DVD capacity

  7. Will this technology last? • It will take time to adjust • Prices need to become more consumer-friendly • Range from $800-$1500 • What will have a very large impact on Blu-ray technology is…

  8. Playstation 3 • If the PS3 is roughly as successful as Sony's past consoles, that would mean somewhere around 100 million Blu-ray players in homes all over the world in around five years or so, not counting standalone players.

  9. So will Blu-ray last? • My opinion is yes. Prices will go down in the near future for both Blu-ray players and HDTVs. Once you experience it, you will not want to watch another movie or TV show in standard definition.
