    摘要： The present embodiments advantageously provide methods and systems for use in decrypting content, and in some preferred embodiments expanding a security environment to distribute the computational processing involved in decryption. In some embodiments, a method for use in decrypting content is provided that receives a first content key at a first system for the decryption of a first track of encrypted content; encrypts the first content key according to a first instance key known at the first system; communicates the first encrypted content key over an externally accessible communication link to a second system; generates the first instance key at the second system independent of the first system; decrypts the first encrypted content key using the generated first instance key at the second system; and decrypts the first track of encrypted content using the first unencrypted content key at the second system.

    摘要： Methods and systems for controlling the distribution of digital content are provided. A license holder acquires protected content and an original digital license to the protected content from a content provider system. The license holder in turn delegates all or part of the grants in that original license to other qualified devices or clients. The content remains in its original, protected or encrypted form while it is delivered from the license holder to the client along with a digital sublicense that the client receives from the original license holder, whereupon the content can then be rendered. The original digital license defines or governs the conditions under which such delegation occurs, and includes terms under which such delegation is permitted to continue in order to enforce the intent of the content provider.
