The term DVD is the acronym for Digital Video Disk, a media which was initially designed for video storage. Eventually, when DVD's popularity soared and became a preferred storage media over its predecessor the CD. With that, the words that made up its acronym was changed to Digital Versatile Disk.
DVD Media Format and Support
With today's super-powered protocols, you should be certain that your DVD player supports the new HD format. High-definition is exactly what its name implies, yet it produces so much more. Most devices that were produced in the last year or two will have these capabilities and they still display the same traditional DVD's from previous decades. The difference in HD is the quality and resolution that you'll be able to view with your crisp, new home theater system.
This is the most common type of DVD data, which is what the DVD was originally designed to do. The invention of DVDs was a giant leap into the future, as it was able to reinvent how videos could work in media players. Most DVD released movies flaunts a video interface that is interactive, a feature that could never be applied to CD videos.
DVD vs CD
he most prominent advantage of DVD over CD is its storage capacity. While CD disks can only store around 650 to 800mb worth of digital file, the DVD on the other hand can hold up to 1 to 16 gigabytes depending on the types. With the advantage of having more storage space, DVD videos boast a higher quality than the CD, perhaps 3 to 4x better. DVDs that could store more than 4.7 gigabytes double layered DVD disks or Double sided.
DVD Players Types
The various model types and styles available are numerous and there are different price levels and options to suit every need. Electronic manufacturers Sony, Philips, Sylvania, Coby, Panasonic and RCA just to name the most popular brands are revolutionizing the way we watch DVD's. There are flip screen models, headrest mounted players, dual Portable DVD Players (some which allow you the flexibility of watching two different films at the same time or play the same film on both screens) and enough screen sizes and resolution levels to satisfy even the most demanding consumer. Aside from that, the popularity of DVDs paved the way for many dvd players to offer alternative methods of playing multimedia files, like those stored in flash disks which can be played through built in usb ports in DVD players.
As far as modern day inventions go, there are definitely more impressive and advanced gadgets than the Portable DVD Player. The smart phones and tablets come foremost to mind - but not many offer as much entertainment value as DVD players, especially when you're away from a wi-fi connection. Aside from that, nothing beats the fun that late night movie marathon with your family or with your friend watching it in front of your wide screen TV than on doing so on your computer or laptop, alone.
