3- Now I hear you asking how much data can be stored on a single BD? More than five times as you would on a DVD. And we all know a DVD holds what guys? 4.7 GB!
4- The blu-ray format was mainly developed to enable recording and playback of high-definition video or HD (Spelled out on the screen)
5- This extra capacity combined with the use of advanced video and audio technology offers consumers a never seen before HD experience.
High-definition video or HD video refers to any video system of higher resolution than standard-definition (SD) video. Which means the picture quality is much sharper and richer than your grandma’s old box television with the wacky knob.
6- The question now is… how is this possible? While current optical disc technologies such as DVD rely on a red laser while the new format uses a blue-violet laser instead, hence the name Blu-ray. The Way it works is:
7- Blu-ray products are backwards compatible with CDs and DVDs. Which means you will still be able to watch your entire DVD collection of Friends on your Blu-ray player and you will be able to listen to Celine Dion belt out her song on the soundtrack of Titanic.
8- BUT if you try to put a Blu-ray disc in your DVD player it will spit it out in your face!
9- When shopping for a new movie how can I tell a Blu-ray disc from a DVD?
A blu-ray disc box will have a blue plastic strip on the top making it more recognizable. (Picture of Mel Gibson)
Just like the one William Wallace had on his face in Braveheart. Blu-ray means more freedom to watch or listen to whatever you want.
10- Like it or not Blu-ray is the format of the future and is the next big thing. It has become the format of choice for leading multimedia companies and has the full support from all major Hollywood studios as the successor to DVD.
An optical disc is a flat, usually circular disc which carries information in the form of data, audio and or video. Examples include CDs, DVDs, and of course our newest addition to the world of technology… blu-ray discs. They are all physically the same size but vary immensely in capacity i.e. how much data you can store onto each of them.
11- And yes if you compare the same movie on DVD to the same movie on Blu-ray you will see a big difference in quality. Which means Gollum from Lord of the Rings will be even uglier if that’s possible. (Picture of Gollum on Screen)
Blu-rays is much better than DVDs precious!
