Local Web Server DRM Decoding for Mobile Media Players

The patent introduces a local web server as an intermediary component between the DRM content storage and the media player. The web server receives HTTP requests from the media player, retrieves DRM content from local storage, and delivers it to the player. This intermediary approach allows DRM functionality to be added without modifying the built-in media player or requiring an exclusive DRM decoding module directly integrated into the OS, thus maintaining security while reducing device complexity.

The patent implements a universal DRM solution using a local web server that can serve multiple media players and handle various DRM-protected content types. The web server provides a standardized HTTP interface that works with different media players and content formats, making the DRM system adaptable to different scenarios without requiring OS-level modifications or exclusive decoding modules for each case.

The local web server acts as a mediator that translates between the media player's HTTP requests and the local file system operations. This intermediary layer provides version independence and adaptability because it uses standardized web protocols that are independent of the underlying OS version or media player implementation, while keeping the added complexity localized to a single modular component rather than requiring widespread system changes.
