Yes that's one form of DRM. Other forms of DRM include: Not being able to backup media on your own physical storage, not being able to access content on the media, not being able to transfer digital content between consoles(offline). Physical is nothing but an illusion of freedom because they need an extremely closed platform to run on. It's kinda poetic that digital games on PC fulfill the desires of people who prefer physical much better than actual physical media on consoles.But they're not lying about on disc DLC. They could very easily hide it, yet they don't. It's the same for installed DLC on digital copies. There you can also see if the DLC was already in the initial game. In fact it's way easier to detect those "lies" on open platforms with digital only media if they ever occur.
Not being able to play a PS4 disk on an XB1 is not a form of DRM. See the two definitions below.
"Digital rights management (DRM) is a systematic approach to copyright protection for digital media. The purpose of DRM is to prevent unauthorized redistribution of digital media and restrict the ways consumers can copy content they've purchased. DRM products were developed in response to the rapid increase in online piracy of commercially marketed material, which proliferated through the widespread use of peer-to-peer file exchange programs. Typically DRM is implemented by embedding code that prevents copying, specifies a time period in which the content can be accessed or limits the number of devices the media can be installed on."
Although digital content is protected by copyright laws, policing the Web and catching law-breakers is very difficult. DRM technology focuses on making it impossible to steal content in the first place, a more efficient approach to the problem than the hit-and-miss strategies aimed at apprehending online poachers after the fact.
Cerebral's Note: Limiting the number of devices media can be installed on refers to putting the media on multiple computers, not multiple brands of consoles. Just an FYI.
Stands for "Digital Rights Management." DRM refers to a collection of systems used to protect the copyrights of electronic media. These include digital music and movies, as well as other data that is stored and transferred digitally. For example, the Apple iTunes Music Store uses a DRM system to limit the number of computers that songs can be played on. Each audio file downloaded from the iTunes music store includes information about the owner of the file and how many times the file has been transferred. The protected files will not play on computers that have not been authorized to play the music.
Digital Rights Management is important to publishers of electronic media since it helps ensure they will receive the appropriate revenue for their products. By controlling the trading, protection, monitoring, and tracking of digital media, DRM helps publishers limit the illegal propagation of copyrighted works. This can be accomplished by using digital watermarks or proprietary file encryption on the media they distribute. Whatever method publishers choose to employ, DRM helps them make sure that their digital content is only used by those who have paid for it.
