Components of Widevine’s Digital Rights Management system, in addition to the functionality of each individual component
Google’s proprietary content protection system for premium media is known as Widevine Digital Rights Management (Widevine DRM for short).
The most prominent content distribution platforms in the industry, such as Google Play, YouTube, Netflix, Hulu, Amazon, and a great number of others, all use Widevine as their content filtering technology.
Widevine is an integrated component that can be found in web browsers like Chrome and Firefox, as well as on devices running Android OS and a wide variety of other over-the-top (OTT) devices. Chrome and Firefox are two examples of web browsers that include Widevine as an integrated component.
In addition to client devices that are capable of running Widevine, the Widevine Digital Rights Management (DRM) ecosystem is made up of Widevine cloud licencing services as well as licenced proxy servers.
The Widevine Cloud Licensing Service is directly operated by Google, and it is responsible for the generation and delivery of DRM licences in response to a request made by a licence proxy server embedded within a content service or DRM an anti-piracy tool. This response is made in response to a request made by the Widevine Cloud Licensing Service. A request was made by the Widevine Cloud Licensing Service, and this response is being provided in response to that request.
In order to satisfy the requirements, an organisation must present their credentials, which are specific to their company, in order to gain access to cloud licencing services.
The user authentication and authorization for DRM licence requests made by client devices are managed by the licence proxy server. These requests are made by client devices. Client devices are responsible for making these requests.
In addition, the Widevine cloud licencing service is in charge of issuing licences, and the licence proxy server is in charge of delivering those licences to clients who have made a request for them.
Client devices include mobile phones that run Android, televisions that run Android, set-top boxes that run Android, and web browsers like Chrome and Firefox. Client devices may also include Android-powered set-top boxes.
It is necessary to have a separate contract with Widevine in order to manufacture Widevine client devices. This is required in order to obtain the key box and CDM module, as well as to test the integration. This is necessary in order to bring the manufacturing process to a successful conclusion.
Because the Chrome web browser has such a large market share in the PC environment, the fact that Widevine DRM content played on Chrome may be simply replicated using an application that records the screen presents a potentially significant challenge.
