Most of you would already come into connect with DRM when you enjoy digital life with your Mac, PC or other popular devices. For example, when you download some movies, music, e-books, TV shows and games, you may be prevented from copying and sharing them to other devices. The reason is that these media files are encrypted with DRM, which contributes to protecting the copyright according to the content creators. Different platforms provide different DRM technologies. In order to make sure that your media files are compatible with all mobile devices, we need to be clear about the leading commercial DRM technologies. Before we get down to discussing the different DRM technologies, we should have a good understanding of DRM.
Digital rights management (also known as DRM) is the access control technologies designed to restrict the usage of copyrighted digital content, such as the movies, TV shows, music, e-books, games, and etc. With the encryption technologies, content providers can grant control and protection over their own digital media. That is to say, DRM is able to prevent customers from possessing, duplicating and sharing digital material and works or converting them to other formats.
With the use of AES algorithm in combination with MD5 hashes, FairPlay is a digital rights management created by Apple Inc. In order to protect the copyright of content creators, Apple FairPlay DRM is built into all the movies and TV shows purchased or rental from iTunes store, which can't be allowed to play on other non-Apple's products except iPhone, iPod, iPad, Apple TV and etc. Previously, all songs purchased from iTunes store between 2003 and 2009 are also protected by Apple FairPlay DRM, you can only listen to these DRM-ed songs on iTunes and Apple devices. Fortunately, after 2009, you can freely enjoy all songs bought from iTunes store.
If you want to enjoy all movies and TV shows purchased or rented from iTunes by fully controlling the use of these media files, the most important thing you should do is to crack the lock of DRM. In this case, you are highly recommended with an easy-to-use yet professional FairPlay DRM removal tool, that is, DRmare M4V Converter, which can not only remove FairPlay DRM protection legally from the iTunes movie rentals and purchases, but also convert the iTunes M4V to MP4 or other DRM-free videos and audios with lossless quality.
