SYSTEMS AND METHODS FOR SECURELY PROVIDING ADAPTIVE BIT RATE STREAMING MEDIA CONTENT ON-DEMAND

摘要

A system for securely providing adaptive bit rate streaming media content on-demand may include a security sever 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.

主权项

1. A method in a media content transmission system, the method comprising:
receiving, by a relay server of the content transmission system, a request for a streaming media content program, the request originating from a secure remote control device communicatively coupled to a remote receiving device; in response to receiving the request, authenticating, by the relay server, the request; selecting, by the relay server, an encrypted segment of the requested streaming media content program, the encrypted segment being one of a plurality of encrypted segments having been stored prior to receiving said request for the streaming media content program, each encrypted segment of the plurality of encrypted segments being a differently encrypted version of a same segment of the of the requested streaming media content program and having a different corresponding decryption key; requesting, by the relay server, the selected encrypted segment from a content storage system of a content delivery network at which the selected encrypted segment is stored; receiving, by the relay server, the selected encrypted segment from the content storage system in response to the requesting of the selected encrypted segment; and transmitting, by the relay server, the selected encrypted segment of the requested streaming media content to enable the remote receiving device to receive the selected encrypted segment in response to the request for the streaming media content program.
