Welcome to my dvd-place. First of all, do you know what dvd is? If not read the following! DVD IS THE NEW FILM FORMAT FOR HOME
USE! One disc (same size as a cd) can contain multiple languages, subtitles and camera
angles. I dont know how to explain, because the picture and sound are soooo good. |
DVD |
DVD, or digital versatile disc, this new medium for watching films, brings consumers the ultimate home cinema experience. A single DVD can contain any full-length film on a 12cm disc, as well as multiple language versions of the film, dubbed or subtitled. The convenience and durability of CD's combined with ease-o-use, exciting features and unparalleled data storage, place DVD's at the forefront of multimedia technology. DVD is a standard already adopted by consumer electronics, computer and entertainment companies worldwide. |
DVD BASIC STRUCTURE |
| At first sight, DVD looks like a conventional
music CD: silvery and waferthin, 12 centimetres in diameter and only 1,2 millimetres
thick. In fact, a DVD disc is two 0,6mm discs which are bonded together. A music CD is a 1,2mm singlesided disc. This structure gives the DVD considerable advantages such as more mechanical stability, hence higher data storage capacity, andbetter resistance to heat and humidity than conventinal CD's |
DVD DISC STRUCTURES |
| The DVD standard allows for one to four
information layers on the same DVD: from a single-sided/single-layer disc with 4,7
gigabytes capacity (DVD-5) to a double-sided/dual-layer disc with 17 gigabytes capacity
(DVD-18). This is the DVD family. This means: dfepending on the total number of layers available, you can have from 7 to 25 times more data stored on a DVD than on a conventional CD |
