摘要： A Service Key Delivery (SKD) system for delivering a service keys to client devices in a communications network. The delivered service keys are operable to be used to decrypt an encrypted key operable to be used to decrypt an encrypted digital content. The SKD system includes a data input interface for receiving a distribution time frame for the keys and a listing of client device identifications. The SKD system also includes a scheduling module to partition at least part of the distribution time frame into a number of time slots in which the number may be based on a variety of factors. The scheduling module assigns the time slots in the partitioned part of the distribution time frame to the client devices based on the identifications in the listing. The SKD system also includes a message generator configured to send key delivery messages to the client devices.

摘要： A source device determines content rights for encrypted content in the first encoding standard using a first rights data file. The source device creates a second rights data file for transcoded content in the second encoding standard. The source device performs a key management operation including communicating a decryption key for the encrypted content in the first encoding standard to a transcoder. The source device transfers the encrypted content in the first encoding standard to the transcoder. The transcoder decrypts the encrypted content, transcodes the content from the first encoding standard to the content in the second encoding standard, and re-encrypts the content in the second encoding standard using a second encryption key. The transcoder then transfers the encrypted content in the second encoding standard to an indicated device.
