摘要

A system for securely providing adaptive bit rate streaming media content on-demand may include a security server of a program distributor that selects, based on a received authorized request, which of a differently encrypted stored versions of a “special segment” of the requested program to deliver to the receiving device during the transmission of the requested program. The selection may be based on a pseudo-random selection process per request for the program based on an identifier of the request associated with the remote control device. The selection of which of the differently encrypted stored versions of the “special segment” of the ordered program to deliver may be=based on the current session. The secure remote then sends to the receiving device the correct decryption key for the receiving device to decrypt the particular encrypted version selected of the “special segment” to be sent to the receiving device.
