DVD Decoder - decode dvd
Generally speaking, DVD Decoders perform three primary functions. Firstly, all commercial DVDs include copy protection to make it difficult to easily make copies of the DVD's data. However, it's legally allowed to be made a copy or backed up for your own private, personal use. The copy protection is called CSS and in order to view the file, a DVD Docoder is necessary to unlock the copy protection. Second, DVD Decoder decodes the MPEG-2 format, recreating the data so that the original images can be viewed. And third, the DVD Decoder makes it possible for these images to be played through a viewing program which is installed on your PC.
Many excellent DVD softwares like DVD Copy, DVD Ripper, DVD Shrink and more can perform the three functions, they can be regarded as DVD Decoder.
However, if you would like to play a standard DVD on a computer or other handy portable players like iPad, iPhone, iPod, etc., you will not only need a DVD player commonly referred to as a DVD drive, but related DVD Decoder. Decoding software is not free. Since the MPEG-2 is a licensed format, licensing and royalties must be paid to the patent holders in order to decode the DVD and view the data on it. If you already have a DVD drive, but require the software to decode the format, this is the reason why there are no free alternatives.
To directly enjoy DVD movies on a computer, you can directly take DVD Copy, DVD Ripper and other DVD related Tools as DVD Decoder to remove DVD Copy Protection, automatically recreate the data and watch DVD movies with it. But if you wanna decode DVDs for enjoying with all popular portable players, you can only use multifunction DVD Ripper and related DVD Converter (like DVD to iPod Converter, DVD to iPad Converter, etc.) as DVD Decoder not other DVD software like DVD Copy, DVD Burner, etc. Refer the left catalog for more DVD Tools and free Download.

DVDs vs. DVD Encoding
DVDs are one of the most popular types of media sold today. They hold feature length motion pictures, videos, audio and countless other types of media such as software and data. DVD's can be played in standalone DVD players and most computers have a DVD drive. If a DVD includes media such as a feature length motion picture, this media has been encoded and sometimes compressed. In order for this type of DVD to be played on a computer's DVD drive, the data on the DVD must first be decoded; this is done with help of computer software. It should be noted that there are many types of DVD formats, hence several types of encoder programs to make a DVD accessible to computer users.
DVDs encode data in a variety of ways. For instance, Dolby Digital data requires a Dolby Digital decoder. The same is true with DTS (Digital Theater System). These are both audio data that require decoding, but many video images stored on a DVD also require decoding including MPEG-2 (this is the most popular video format for DVD's). It should be noted that in order to play a standard DVD, the DVD player is not enough, you also need the software to decode the images making the data fully functional.
DVDs work on two standards; NTSC and PAL, each of these standards have different formats. For instance, NTSC requires 30 frames per second in a 60 field sequence. For PAL, 50 fields per second are required; however movie images are filmed at 24 images per second. In order for a film to meet either standard, encoding must take place. Encoding also allows the compression of video images - this is the process of making a data file smaller in storage size. Usually static data is put aside to allow compression to take place. For instance, a 30 minute talk show in which the background is static and never changes can be compressed more than a 30 minute video of a race car moving quickly around a track.
