subject: Simplified Dvd Working Process Explored [print this page] Today once again going to take you through an interesting journey, that is definitely going to enrich your knowledge about DVD working process. A DVD is very similar to a CD, but it has a much larger data capacity. A standard DVD holds about seven times more data than a CD does. This huge capacity means that a DVD has enough room to store a full-length, MPEG-2-encoded movie, as well as a lot of other information.
All about Contents of a DVD movie:
Up to 133 minutes of high-resolution video, in letterbox or pan-and-scan format, with 720 dots of horizontal resolution (The video compression ratio is typically 40:1 using MPEG-2 compression). Soundtrack presented in up to eight languages using 5.1 channel Dolby digital surround sound Subtitles in up to 32 languages DVD can also be used to store almost eight hours of CD-quality music per side.
Why DVD Scores Over VHS tapes?
- DVD picture quality is better, and many DVDs have Dolby Digital or DTS sound, which is much closer to the sound you experience in a movie theater.
- Many DVD movies have an on-screen index, where the creator of the DVD has labeled many of the significant parts of the movie, sometimes with a picture. With your remote, if you select the part of the movie you want to view, the DVD player will take you right to that part, with no need to rewind or fast-forward.
- DVD players are compatible with audio CDs. Some DVD movies have both the letterbox format, which fits wide-screen TVs, and the standard TV size format, so you can choose which way you want to watch the movie. DVD movies may have several soundtracks on them, and they may provide subtitles in different languages. Foreign movies may give you the choice between the version dubbed into your language, or the original soundtrack with subtitles in your language.
DVD FAQs for you:
What does "DVD" stand for?
"DVD" stands for digital versatile disc, but some sources declare that it doesn't stand for anything anymore.
What is the difference between DVD+R and DVD-R?
DVD+ ("plus") and DVD- ("dash") are two competing DVD formats. You may remember the "war" between the Betamax and VHS formats for domination of the VCR market. The big difference with DVD+R vs. DVD-R is that there are hybrid (dual-format) drives capable of reading both types. Many companies have taken sides -- the DVD Forum is a group of manufacturers that support DVD-R, while the DVD+RW Alliance support that format.
