What exactly does it mean when someone says “Multi-DRMan anti-piracy tool”?
Early digital rights management (DRM) solutions were given by each DRM provider in the form of a client software development kit (SDK) or embedded DRM. These early DRM systems supported a limited selection of devices and adhered to a single, proprietary DRM protocol. “Multi-DRM” is distinguished from “Single DRM” by the fact that major platforms (browser or operating system) make available multiple digital rights management systems (DRMs), such as “PlayReady,” “Widevine,” and “FairPlay.” These DRMs are then applied to content in accordance with a standardised specification. “Single DRM” refers to a single digital rights management system.
Depending on the capabilities of the specified target platform, multi-DRM protection can be applied to data streams of either the DASH or HLS type. When safeguarding DASH content, both PlayReady and Widevine DRM are utilised. PlayReady and Widevine DRM both support MPEG CENC, which is commonly referred to as Common Encryption. In order to support Multi-DRM on Apple systems like macOS and iOS, you will need to apply FairPlay DRM to a distinct HLS content. To put it another way, you need to create and offer not one, but two different types of DRM content for each and every piece of unique content, specifically DASH and HLS.
Support for many digital rights management systems in addition to web browsers
Traditional “single DRM” systems required users to install a separate browser plug-in, such as “Flash,” in order to secure audio and video content that could be played on a web browser. This was necessary in order to prevent unauthorised use of the content. This had to be done in order to stop unauthorised usage of the content, which was a need. On the other hand, support for plug-ins within web browsers is gradually being phased out because of numerous performance and security issues. As a result, digital rights management (DRM) systems that are dependent on plug-ins are gradually being phased out of the market.
One of the benefits that multi-DRM systems have to offer is the capacity to play DRM content on a web browser without the requirement of a separate plug-in being present. You may eliminate the need to develop native programmes for each client platform, such as personal computers and mobile devices, by enabling the playing of DRM content on the majority of platforms with a single web application. This enables you to play DRM content on the majority of platforms.
Due to the fact that the content needs to be decrypted before the client can access it in order to play it back, this step takes place before playback actually begins. The customer has access to the decryption key for the specific content ID that was used throughout the process of encrypting the movie as a result of the digital rights management system. This enables the customer to watch encrypted movies at their leisure. This was done so that the consumer could watch the movie without worrying that anyone else would be able to see what they were watching. This was done in order to honour the customer’s right to the privacy and discretion of their personal information (DRM). It is generally customary to abbreviate Content Decryption Module as CDM, which stands for Content Decryption Module. The Content Decryption Module is a specialised piece of software that the user’s device or web browser will typically incorporate as an integrated function. It is possible to refer to the Content Decryption Module (CDM) by its full name, which is the Content Decryption Module. This component is responsible for deciphering the information that has been received, which was encoded in a certain format. CDM is already pre-installed on all products that adhere to the Encrypted Media Extensions standard and have the capability of playing encrypted media files (EME). Once the video content has been encrypted and then made available to the player after it has been decoded, the player will be able to use the content of the video. Decryption of the video content will take place.
