System and method for implementing content protection in a wireless digital system

摘要

A system includes a line-based receiver for receiving protected content from a source and a line-based transmitter for providing the protected content to a destination. The protected content is secure, such as by using a High-bandwidth Digital Content Protection (HDCP) mechanism. Between the line-based transmitter and receiver is a wireless transmitter and a wireless receiver. The wireless transmitter establishes an encrypted wireless link with the wireless receiver according to a second encryption mechanism. The wireless transmitter is further configured for receiving the protected content from the line-based receiver, encrypting the protected content according to the second encryption mechanism, and wirelessly transmitting the encrypted protected content. The wireless receiver is further configured for receiving the wirelessly transmitted protected content from the wireless transmitter and decrypting the protected content according to the second encryption mechanism.

主权项

1. A system comprising:
a line-based receiver for receiving protected content from a source, the received protected content being encrypted according to a first encryption mechanism; a wireless transmitter for establishing a secure wireless link with a wireless receiver according to a second encryption mechanism, wherein the wireless transmitter is further configured for receiving the protected content from the line-based receiver, encrypting the protected content according to the second encryption mechanism, and wirelessly transmitting the encrypted protected content over the secure wireless link; the wireless receiver for establishing the secure wireless link with the wireless transmitter, the wireless receiver being further configured for receiving the wirelessly transmitted encrypted protected content from the wireless transmitter and decrypting the received encrypted protected content according to the second encryption mechanism to output the protected content; and a line-based transmitter for receiving the protected content from the wireless receiver and transmitting the protected content to a destination, the transmitted protected content being still encrypted according to the first encryption mechanism.
