Abstract

Secure content transfer systems and methods to operate the same are disclosed. An example system includes a content server to encrypt content according to an encryption key, and to transfer the encrypted content, the encryption key and a license to a client that supports a digital rights management technology. The example system further includes a broadcast system headend to determine the encryption key, wherein the broadcast system headend is physically separate from the content server, and a digital rights management license server to provide the license.
