摘要： Methods and apparatus for conditional access of non real-time (NRT) content in a distribution system. A method includes encrypting NRT content with a control word (CW) to generate encrypted NRT content, providing the CW to entitlement control message (ECM) generators, receiving ECMs from the ECM generators, wherein each ECM comprises a unique encryption of the CW to provide conditional access to the CW, and providing the encrypted NRT content and the ECMs for transmission over a distribution network. An apparatus includes a synchronizer configured to provide a CW to ECM generators and receive ECMs from the ECM generators, wherein each ECM comprises a unique encryption of the CW to provide conditional access to the CW, and a management module configured to encrypt the NRT content with the CW to generate encrypted NRT content and provide the encrypted NRT content and the ECMs for transmission over the distribution network.
