For those who have not yet settled on which high definition disc to invest in, this article will help bring several issues to light. First of all, the potential video and audio quality remain alike between both formats, HD-DVD and Blu-Ray. The difference lies in the laser that reads the disc; where the former uses the identical red laser used to read DVDs, the latter employs a blue laser that reads only Blu-Ray. Both lasers can decode an identical amount of information, called the bitrate. A bitrate can be labeled as the amount of “bits” decoded per second. Generally, the higher the bitrate the higher the quality of video/audio. So a bitrate of, say, 30mbs (megabytes per second) should be preferable to a meager 10mbs. The average hi-def picture, with its superior clarity and contrast, can maintain a bitrate between 15mbs-35mbs; compare this with an ordinary DVD, which averages 2mbs-7mbs.
With its ability to store and transmit at a higher bitrate, hi-def media easily trumps the quality of DVD. This higher bitrate allows for less compression, and thus can retain most of the clarity from the original master print of a movie; whereas a DVD will look blown-up and...
