Blu-Ray Disc and DVD

Blu-ray Disc offers many features and benefits over DVD, although BD only supports HDTV.

better image resolution
Blu-ray Disc offers full 1080p* video resolution for pure, pristine picture quality.

Excellent audio quality
Blu-ray Disc provides up to 7.1 channels of native compressed surround sound for crystal-clear audio entertainment.

Protect the entertainment industry
DRM is the copyright protection scheme used by the media industry to prevent piracy, and Blu-ray technology in this field is really exciting. There is a possibility for users to copy the contents of a disc a limited number of times.

connectivity

BLU-RAY DISC and DVD
DVD Compatibility

BD has a large storage capacity and offers 5 times the capacity of a DVD, just as a DVD can store 5 to 10 times more than a CD. This is due, among other reasons, to the use of a blue laser instead of a red one and to improved lens specifications, which allow a much smaller focus laser beam allowing the recording of much smaller holes and higher density on the disk. Due to the fact that the data layer on a Blu-ray disc is placed much “closer” to the laser lens than on a DVD, there is less distortion, resulting in significantly improved tolerances. Therefore, more precise and ultra-high storage densities are now possible. Although Blu-ray cannot fit an entire series of HD-quality material on a single disc, it could potentially fit an entire series of standard DVD-quality material.

The advantages and disadvantages of a Blu-ray disc over DVD are given below:

ADVANTAGE

1. Maximum image resolution
2. Larger capacity; Offers up to 5 times the capacity of DVD
3. The best audio quality
4. Scratch-proof disc
5. Integrate DVD too
6. PC supports comics
7. Greater interactivity through BD-Live
8. Sony and Philips quality support
9. PlayStation 3 Stands
10. Protect digital copy rights for the entertainment industry and prevent piracy

DISADVANTAGES

1. High price
2. Requires HDTV
3. Although the storage capacity is high, it cannot hold HD content for a longer time on a single disc
4. HD-DVD player competition, and it’s cheaper, is a threat to the Blu-Ray market. Blu-ray also faces competition from Video on demand and new technologies that allow access to movies in any format or device, such as the Digital Entertainment Content Ecosystem or Disney’s Keychest.

CONCLUSION

Moviegoers have shelled out an extra $5 to $10 per movie. Since BD is backward compatible with DVD, new technology takes care of old favorites and DVDs that were picked up in the past won’t go to waste and will be put to good use by BD. Blu-ray makes a big difference, the media contains much more video data than DVD, the quality improvement is quite impressive on LCD TVs. I would definitely recommend getting a Blu-ray player or a PS3. BD is there to stay for a long time!
