Abstract
A method for delivering encrypted content to a subscriber terminal on-demand through a communication network is provided. The method begins when SRM receives a request for content from the subscriber terminal. In response to the request, the SRM directs a video server to transmit the content as an unencrypted transport stream to an encryptor. The packets in the unencrypted transport stream include a header with a destination address associated with the subscriber terminal. The encryptor encrypts the content in the unencrypted transport stream to generate an encrypted transport stream. The encryptor also inserts in the packet headers of the packets in the encrypted transport stream the destination address associated with the subscriber terminal obtained from the packet headers in the unencrypted transport stream. Finally, the encrypted transport stream is transmitted to the subscriber terminal over the communication network.
