摘要 |
A system and method for use in a communication network (100) that communicates with a plurality of digital content servers (150) to provide selected digital data files, including video and audio files, for download to a subscriber device (112). A segmentation controller (1330) is provided for dividing the selected digital data files into segments (1315-1317). An encryption controller (1340) is provided for compressing and encrypting each of the segments (1315-1317) with a selected one of a plurality of encryption keys. The segments (1315-1317) are then transmitted at or above the average bandwidth of the communication network (100) to a subscriber device (112). A copy of the decryption keys are transmitted to the subscriber device (112) to enable playback of the selected file only with a current verification of the subscriber device (112).
