Abstract

A system, method and apparatus for implementing a wireless point-to-point interface that securely and robustly delivers digital 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 HDMI content over cable. The system, method and apparatus is also applicable to the delivery of other types of content traditionally delivered over cable, including but not limited to Digital Video Interface (DVI) content, composite video (CVSB) content, S-video content, RGB video content, YUV video content, and/or various types of audio content.

Claims34

Dependent claims

A system for transferring media content from a content source to a content sink, comprising:

a first wireless media adapter comprising first conversion logic and a transmitter, wherein the first conversion logic receives an output signal representing uncompressed video data and encoded for transmission over a wired communication interface from the content source and converts the output signal to a format suitable for wireless communication wherein the conversion does not include applying lossy compression to the uncompressed video data and wherein the transmitter wirelessly transmits the converted output signal over a first ultrawideband (UWB) radio frequency (RF) channel located in the frequency range of 3.1 gigahertz (GHz) to 10.6 GHz;
and
a second wireless media adapter comprising a receiver and second conversion logic, wherein the receiver wirelessly receives the wirelessly-transmitted signal, and wherein the second conversion logic converts the wirelessly-received signal into an input signal representing the uncompressed video data and encoded for transmission over the wired communication interface and transmits the input signal to the content sink.

A system comprising:

(a) a content source, wherein the content source comprises
(i) an audio/visual (A/V) source that generates an output signal representing uncompressed video data and formatted for transmission over a wired communication interface, and
(ii) a first wireless media adapter that receives the output signal, converts the output signal to a format suitable for wireless communication wherein the conversion does not include applying lossy compression to the uncompressed video data, and wirelessly transmits the converted output signal over a first ultrawideband (UWB) radio frequency (RF) channel located in the frequency range of 3.1 gigahertz (GHz) to 10.6 GHz;
and
(b) a content sink, wherein the content sink comprises
(i) a second wireless media adapter that wirelessly receives the wirelessly-transmitted signal and converts the wirelessly-received signal into an input signal representing the uncompressed video data and formatted for transmission over the wired communication interface, and
(ii) an A/V presentation system that receives the input signal and generates an A/V presentation to a user responsive to the input signal.
