System, method and apparatus for wirelessly providing a display data channel between a generalized content source and a generalized content sink
First Claim
1. A wireless media adapter, comprising:
- a digital media interface coupled to a media device over an Inter-Integrated Circuit (I2C) bus; and
a wireless transceiver coupled to the digital media interface;
wherein the digital media interface and the wireless transceiver are configured to wirelessly relay a portion of an I2C transaction between the media device and a remote wireless media adapter, thereby providing a Display Data Channel (DDC) channel.

Abstract
A system, method and apparatus for implementing a wireless point-to-point interface that securely and robustly delivers media content from a generalized content source to a generalized content sink. The system, method and apparatus performs in a manner that is sufficiently secure and robust to serve as a replacement for the delivery of High-Definition Multimedia Interface (HDMI) content or Digital Video Interface (DVI) content over cable. An aspect of the present invention performs Inter-Integrated Circuit (I2C) decoding and encoding operations to implement a wireless HDMI or DVI interface between the generalized content source and the generalized content sink. The I2C decoding and encoding operations are performed as necessary to support the reception, decoding and transmission of a Display Data Channel (DDC) channel.
