Abstract:
A system architecture allows for the transmission of multiple HDCP encrypted audio/video streams over a single unified cable to multiple receivers using a daisy chain topology. Each individual audio/video stream is first encrypted and then combined into a uniform stream, and the uniform stream is transmitted to each of the receivers. Each receiver contains a decryption engine that operates independently of the engines in the other receivers, therefore allowing each receiver to select to a unique channel and decrypt and display one of the audio/video streams.
