Encrypted Media Extensions (EME) is a technology used to provide digital rights management (DRM) for multimedia content that is played on the web. EME is a specification developed by the World Wide Web Consortium (W3C) to provide a standard for content providers to encrypt their media content, such as movies and TV shows, so that it cannot be copied or otherwise distributed without authorization.
With EME, content providers can encrypt their media content using DRM technologies, and the encrypted content can only be played in a web browser that supports EME and has the necessary DRM licenses. This allows content providers to control how their content is used and ensure that it is only played within the context of the website or app where it was intended to be played.
EME has been controversial, with some people opposing it on the grounds that it restricts the open nature of the web and may limit access to certain types of content. However, many content providers view it as an essential tool for protecting their rights and their content from piracy.
