Systems, methods and apparatuses for the secure transmission of media content
First Claim
1. A system for displaying encrypted media content comprising:
- a local device, comprising;
a computer processor configured to control playing of the encrypted media content including performing a navigation control operation using unencrypted media meta data;
a first communication interface configured to transmit an association encryption envelope and, according to the navigation control operation, the encrypted media content; and
a display device, comprising;
a second communication interface coupled to the first interface configured to receive the encrypted media content and the association encryption envelope transmitted by the local device;
a decryption engine configured to decrypt, using a private key of the display device, the association encryption envelope to recover a symmetric encryption key used to encrypt the encrypted media content and decrypt the encrypted media content using the recovered symmetric encryption key; and
a decoder configured to decode the decrypted media content for display on a display screen according to the navigation control operation.

Abstract
The systems, methods and apparatuses described herein permit encrypted media content to be displayed by a display device under control of a local device. The local device may comprise a computer processor to control playing of the encrypted media content and a first communication interface to transmit an association encryption envelope and, according to the control, the encrypted media content. The display device may comprise a second communication interface coupled to the first interface to receive the encrypted media content and the association encryption envelope, a decryption engine to decrypt the association encryption envelope using a private key of the display device to recover a symmetric encryption key used to encrypt the encrypted media content and decrypt the encrypted media content using the recovered symmetric encryption key, and a decoder to decode the decrypted media content for display on a display screen according to the control.
