1980s  Introduction of CD’s with 650MB’s of storage
capacity
1990s  Introduction of DVD’s with 10x increased capacity
High Definition (HD) experience  Competition between Sony
and Toshiba began
Sony  Blu-Ray Disks (25G Storage space)
Toshiba  HD-DVD (15G Storage Space)
February 2008  Toshiba announces that they would no
longer manufacture HD-DVD players or drives
Now, Blu-Ray is the new generation of HD technology

Higher capacity on a single disc
◦ Dual layer  50 GB; 10 layers  250 GB
◦ High Definition video (and more)
 HD = 1080 vs. SD = 480

Interactive features for Blu-Ray disc players
◦ Java coded menus vs. pre-rendered MPEG menus
◦ Connect to Internet

Price
◦ Most Blu-Ray players cost $200-400 at best
◦ In comparison, HD-DVD players sold for $100
and several DVD players are under $100
◦ Only really worth it for HDTV

Profile Confusion
◦ Older Blu-Ray player models (1.0, 1.1) can’t
handle certain special features that come on
discs
◦ Not the case with HD-DVD

Facts
◦ Blu-ray disks are superior to HD-DVDs
◦ Blu-ray disks are much more expensive than regular DVDs
◦ Quality of picture depends on disk, player, and TV

Conclusion
◦ It’s still too expensive to convert to Blu-ray for the average
consumer
◦ Increase in quality is not worth the increase in price
◦ Blu-ray disks will eventually take over DVDs
