Abstract:
A storage device and method for providing a scalable content protection system are disclosed. In one embodiment, a storage device is provided comprising a memory operative to store a plurality of versions of content, wherein each version of the content is of a different quality and is associated with a different level of content protection. The storage device receives information from the host identifying a level of content protection supported by the host. The storage device sends, to the host, a version of the content that is associated with the level of content protection supported by the host, wherein the version of the content is sent to the host using the level of content protection that is supported by the host. In another embodiment, different levels of content protection are applied to different types of content.
