DVD, or Digital Versatile Disc, is the latest hometheater craze. Every DVD, encoded with over 133 minutes of video, various camera angles, multiple subtitle languages, and special features, packs a supreme video punch.
A DVD's video output is very high resolution. Unlike VHS tapes, DVDs never lose their picture quality from repeat viewing. Also, DVDs are recorded in MPEG2 format, meaning the original picture quality is better as well. Many times, a DVD features various camera angles as well. Since storage space on DVDs is extremely large, movie producers add on extra footage if they can, making the DVD experience even more enjoyable.
The audio on a DVD is usually encoded in Dolby Digital Surround Sound, with 5.1 channels. However, for those non-home-theater people, it can be mixed down to stereo sound. Like the multiple camera angles on the video side, the audio side of a DVD may feature extra soundtracks and songs.
First introduced in Japan, DVDs have quickly become the rage in the United States. As DVD players come down in price and more DVDs are released on the market, more people are joining the DVD bandwagon.
