A Digital Rights Management System is a system to enforce the rights of owners of digital media, software, or devices. The system controls the use of protected material by limiting the number of times a song can be played or limiting the number of copies made. Digital Rights Management or DRM content protection identifies the source or owner of the material or prevents the material transfer from one device to another.
In other words, Digital Rights Management (DRM) refers to the technological protection measures used to prevent unauthorized access, copying, use and distribution of copyrighted digital media and information. Various products and services employ DRM to protect copyright and related rights. It is in the video, audio, E-books, digital software, video games, and digital television applications.

DRM Content Protection and DRM Encryption Meaning
The term DRM Content Protection refers to several different processes used to control the use of digital media, software, or devices designed to prevent unauthorized duplication or use of the protected material. Some of the included processes are:
Digital Rights Management (DRM): Refers to a range of technologies used to enforce the rights of digital media owners, particularly concerning the use of copyrighted material. For example, DRM content protection ensures that the protected material is only played on specific devices or controls the transfer of protected material from one device to another. The way DRM works usually depends on the content type and the distribution platform. Still, even when those things are the same, two content providers can use different methods based on the level of restrictions they want to apply.
DRM Encryption: Process of encoding the protected material in a way that makes it unreadable without the correct key. For example, material encrypted using the Digital Rights Management (DRM) process may require a computer or device to be registered to receive the decryption key. The main reason DRM creation was to protect the copyright holder’s interests. When you purchase a copy-protected file, you aren’t actually purchasing the file itself, you’re purchasing a license to use the file. This license is held in a database on a DRM server, and this database is what DRM Encryption protects.
What is DRM Protected Video Content and Streaming?
DRM Protected video content is only available to people who have the right to access it. A video file protected by DRM encryption will no longer be accessible by just anyone. DRM protects the video file by ensuring the content is stored and transmitted in an encrypted format so that only authorized users and devices can access it. Multi-DRM schemes encrypt and package the video content before streaming for improved and more excellent device compatibility. When a user attempts a video playback, the video player requests a key from the license server. Before issuing a license response with a decryption key, the server checks for the authorization of the user and device. Finally, the player decrypts and plays the content for the user.
How to DRM Protect a Video File?
When we upload video content on websites or release premium content on online platforms, a major concern is content security. There are chances that someone may download and misuse the video content if it is not protected or secured. Also, there are various methods available to protect digital content so that no one can copy or download the content unauthorizedly and misuse it. One such way is implementing DRM or Digital Rights Management to protect a video file. Below is a DRM Workflow mechanism.
Source: Input video files upload or transfer to cloud storage such as AWS S3.
Encoding: The input video file is packaged and encoded into Adaptive Bitrate Streaming (ABR) formats like HLS or MPEG-DASH.
Encryption: The video file encrypts with digital keys provided by the DRM License provider during the encryption process.
Storage: The video files transfer to a Content Delivery Network (CDN) such as Amazon CloudFront.
Authentication: The video player makes an authentication request from the DRM server to ensure the license validity.
Playback: Once authenticated, the video player unlocks the video and allows for video playback.

What is DRM Protected Content?
DRM Protected content is any content that is protected by DRM, this means that there are certain restrictions on the video. These restrictions ensure that your video content can be consumed by only the users who you want to access the video in the manner you want them to access it.
DRM ensures that your content is protected and can’t be pirated by anyone. Every access to the DRM protected content is validated before the user can access the content.
DRM or Digital Rights Management ensures that your content is only accessible by authorized users. You can even restrict access in terms of devices, browsers, geo-location, IP, and more.
How DRM Works?
DRM Protection works alongside encryption, the videos are first encrypted and the encryption key is hidden in the CDM(content decryption module).
Every time a user clicks on the play button, a license request is created and verified by the DRM server and sent back to the player, after the player sends the license key to the CDM and the DRM content is decrypted and sent to the player in small chunks.
DRM Protected Content Examples
Any online streaming is an excellent example of DRM protected content. Online platforms use DRM to protect their content before releasing it online.
Here are a few examples of DRM protected content
- Online Video Streaming: Users stream content online through a browser or application. Here every view is validated via the license server. Any video streamed through DRM can’t be downloaded and screen recorded in most cases.
- Video games: Whenever you buy a game from a store online, instead of buying that you are basically buying the license to play that game on your device. Whenever you buy a game on Steam, PSN, or Nintendo store, you get a license to download and play that game which is added to your account. This license allows you to download the game anytime you want.
- Audio streaming: DRM in audio streaming’s case works very similar to the ones in video streaming. DRM ensures that any audio streamed through the respective music player can’t be downloaded.
What are the Benefits of DRM Protected Content?
DRM lets content creators decide what should be done with their content, and it offers many advantages, such as:
- Protection from any revenue loss due to piracy
- Restricts any unauthorized access to the content.
- Prevents any piracy of the content
- Provides an extra level of security to the content
There are several major devices and browsers that support DRM. One of the most widely used DRM is Google Widevine and Apple Fairplay.
Enable Protected Content on your Chrome Browser
Some sites use protected content identifiers on your device to provide better-quality playback. When you go to those sites, Chrome checks your device’s protected content identifier setting to find whether the site can use the identifier. Chrome allows sites to use protected content identifiers by default.
At times chrome browser automatically blocks protected content, In such cases the settings are turned off, you can turn it on by going into your browser setting.
What is a DRM Server?
A DRM server is a database that stores information on the files licensed to you. A DRM server hosts on a server on the Internet or a local database on your computer. The DRM server is encrypted by DRM Encryption.
What is the difference between DRM and copyright enforcement?
Copyright restricts who can distribute media, while DRM software restricts how users access protected media. Copyright provides leverage against illegal distribution. It means the largest distribution platforms must already adhere to the demands of large publishers, studios, and software companies.
How do web browsers support DRM-protected video streaming?
DRM-protected video streaming consumption is by using Smart HTML5 media player. The player uses the Encrypted Media Extensions (EME) API to enable the playback of the protected content.
