Method and system for wireless digital multimedia presentation

Abstract

A system for sending multimedia data between a first High Definition Multimedia Interface (HDMI) component and a second HDMI component that is engaged with a displayer of multimedia data includes a first Digital Visual Interface (DVI) component receiving HDCP-encrypted multimedia data from the first HDMI component over a wire. A wireless transmitter sends data from the first DVI component to a wireless receiver, preferably at 60 GHz, and the receiver in turn sends the data to a second DVI component. Neither DVI component encrypts or decrypts data. The second DVI component sends the multimedia data to a second HDMI component for decryption and display on, e.g., an LCD or plasma display.
