Digital Rights Management – What Is DRM Technology


Have you ever heard of something called DRM? Or put it simply, have you ever encountered such a situation as below?

  • You purchased a movie from iTunes store and would like to put it on your newly bought Samsung Galaxy S6 for watching. But it seems impossible to get it done since it continuously displays errors like “Unsupported Format” or something else.
  • You meet the same problem when you want to enjoy some audiobooks bought from Audible or iTunes on your Sandisk Sansa MP3 player. It won’t allow you to copy the audiobook files to your player by keeps saying the file format is wrong.

If you ever have such an experience before, you’ve already trapped by the DRM technology which we are talking about in this article. But what does DRM actually mean? Why would it restrict the use of certain digital contents we legally paid for? In order to make things clearer to you, we are about to explain in the following article what DRM technology actually is while providing you an ultimate solution to bypass DRM lock easily.

What Is DRM

DRM (Digital Rights Management) is a class of copy protection technologies that are used by hardware and software manufacturers, publishers, copyright holders, and individuals with the intent to control the use of digital content and devices after sale; there are, however, many competing definitions. With first-generation DRM software, the intent is to control copying; with second-generation DRM, the intent is to control executing, viewing, copying, printing, and altering of works or devices. The term is also sometimes referred to as copy protectioncopy prevention, and copy control, although the correctness of doing so is disputed. DRM is a set of access control technologies.

Generally speaking, DRM is an anti-piracy technology adopted by digital copyright owners to restrict the use of their digital materials and works, including software, movies, music, etc by others. The particular purpose of DRM is to prevent people from accessing, duplicating, and sharing copyrighted digital files in ways that the owners don’t like them to.

DRM Technology Used in iTunes Media Content

Among the various forms of DRM, the most commonly known one is FairPlay, a DRM technology developed and adopted by Apple to create its media content in iTunes store, including movies, TV shows, iBooks as well as audiobooks.

Take iTunes movies as an example. Because of the FairPlay DRM encryption, iTunes movies, TV shows and music videos are all formatted as .M4V files which can only be recognised by Apple-approved devices or software. As a result, users can’t copy, re-encode or share the video files even though they have already get them paid legally.

Worse still, for the movies rented from iTunes, users only get 30 days to keep and watch the movie from the day they rented the file and 24 hours (in US) or 48 hours (other countries) to finish watching it once started. The rented file will be taken back automatically by iTunes when it expires.

Best Solutions to Unlock DRM

Currently, the most popular yet effective way to get rid of DRM lock from protected media content is to use a third-party DRM removal tool, such as Requiem or TunesKit. Requiem is one of the best free iTunes DRM remover used by most users who are running Mac OS X lower than 10.7 and iTunes lower than 10.6 since it has stopped upgrading for a long time. TunesKit is not a freeware, but it could be the best shareware to remove DRM from iTunes movies and TV shows with the fastest speed by preserving the original video quality like Requiem does. And the best part is that TunesKit works with the latest Mac and Windows OS as well as latest iTunes. And it will keep the pace with the trends to support the latest computer system and iTunes versions continuously.
