Features of DVD Players
Although a DVD player reads the data on discs just like a CD player, both are quite different in many aspects. The basic difference between these two electronic gadgets is the additional features that come with a DVD player. A DVD player can read and even write on a DVD disc while a CD player can do none of these things. This is because the storage capacity and the data storage method quite vary between a DVD and a CD.
A DVD is designed to allow much more space for data storage due to the smaller pit and track size and advanced data correction methods. Along with this basic advantage, DVD technology also uses MPEG-2 compression method that can reduce a full-length movie on a DVD disc. In addition, a DVD can also store information on two layers of each side thus a DVD can store more than 12 GB of digital information on both their sides.
Here is a list of features that made DVD players so popular in home video market
Better data storage capacity
A single sided DVD can store more than 4.3 GB of digital information. You can store movies, music or large files like encyclopedia on a single disc. Likewise, you can encode a movie of 2 hours duration on a DVD disc while it may require multiple CDs for the same task.
DVD players can also read data stored on multi-layered DVD discs which have much more capacity than a single sided, single layer DVD disc. It is not surprising that such multi-layered DVD discs can store enormous amount of information.
Compatibility with other formats
A DVD player can play music CDs, Video CDs and can also write data on a CD disc. DVD audio is the latest thing that offers much better sound quality than CD music. Newer DVD player can encode audio data in advanced 192kHz/24-bit scale which is catching up with music lovers and movie buffs. With a DVD player, you can play files of all these formats so a DVD player is an excellent replacement for a CD player as well.
DVD players come with Dolby digital surround sound decoder so they are compatible with receivers that have Dolby sound system. Similarly, most DVD players can also offer DTS sound features with their integrated DTS decoders.
Connectivity
DVD players provide various connectivity options like component, S-Video or coaxial or fibre optic cable connections based on the receiver that you are going to connect. S-Video and fibre optic cables are excellent options and ensure better picture and colour quality.
DVI connection or HDMI are additional features that help to connect a DVD player to a HDTV like LCD TV.
Other features
DVD players also offer useful features like selecting the specific part of the movie without using fast forward or rewind just by going over the main menu. A few models also allow you to book mark you particular scenes so that you can return to them with ease.
Another useful feature of a DVD player is that it will automatically resume from the scene where it was stopped earlier.
The auto power-off feature of a DVD player will switch off your DVD player when it is not running a movie, thus saving power too.
