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.
