What Is Blu-Ray?
Blu-ray is simply referring to the way the information is read from the media (disc). Blu-ray discs have up to 20 layers of information stored on the same sized DVD as used by standard DVD players. Blu-ray players can read that information because of the blue-violet laser that has a shorter wavelength. Standard DVD players have a red laser that has a larger wavelength, limiting the player’s ability to read the more compressed data on the Blu-ray disc.
Is There A Visible Difference In Quality?
Many say that they cannot tell the difference in video quality between a standard DVD and a Blu-ray. Blu-rays and Blu-ray players are also more expensive.
The key is in how the media is being viewed. An HDTV is a must for viewing Blu-rays. Blu-rays were developed for playback in a high-definition environment.
Are Blu-Ray Players Compatible With DVD Disks?
Yes, most players play both formats and some are upgraded to make DVDs look even better. Depending on the video processors being used, this upgrade to the DVD playback can occur in the TV itself or in the player. This is done by converting the frame to a high-definition scale; making it fit the high-definition television and appear clearer.
So Is Blu-Ray Worth The Extra Money?
The answer depends on who you talk to. Most viewers report a better image when viewing a Blu-ray movie. However, viewing a standard DVD and a Blu-ray on the same television that is not high-definition would result in minimal gains.
Manufacturers can cram lots of extra content on the Blu-ray discs so if you like the special features and commentaries, Blu-ray is a good choice.
Another selling point for Blu-ray is that viewers get their movies faster. Movies are being released on different schedules and often Blu-ray discs are available first.
