In one embodiment, a host device creates a super-distribution token by encrypting a content encryption key with a super-distribution key and stores the super-distribution token and encrypted content retrieved from a source storage device in a target storage device. In another embodiment, a host device provides a super-distribution token to a server, wherein the server is configured to generate an activation token from the super-distribution token, receive the activation token from the server, retrieve a content encryption key from the activation token, and decrypt encrypted content received from a storage device using the content encryption key retrieved from the activation token.

Host device and method for super-distribution of content protected with a localized content encryption key

A storage device and method for resuming playback of content are provided. In one embodiment, a storage device comprises a memory operative to store a plurality of versions of content. The storage device receives a request for one of the versions of the content from a host, provides the requested version of the content to the host, and provides bookmark information from which the host can determine a location where to resume playback of the content, wherein the bookmark information indicates where playback ended for a different version of the content.

A memory device and method for embedding host-identification information into content are disclosed. In one embodiment, a memory device is provided comprising a memory operative to store content and a controller in communication with the memory. The controller is operative to receive a credential comprising host-identification information from a host in communication with the memory device, authenticate the host using the credential, receive a request from the host to play content stored in the memory, embed the host-identification information into the content, and send the content with the embedded host-identification information to the host.
