Wireless video/audio signal transmitter/receiver

Abstract

This invention is new to the field in two ways: [1] it sends audio/video signals wirelessly between tablet computing devices and smartphones to projection devices instead of using attached cables, and [2] it does not require an app, a second computing device, a driver, a download, or a “jailbreak” of the computing device to function properly.

1 - 3 . (canceled) 
     
     
         4 . A method of wirelessly mirroring video from a mobile device to a display screen, the method comprising:
 at a transmitter device:
 by at least a first one or more video and audio signal processors preconfigured to provide communications with a second one or more video and audio signal processors:
 receiving a video and audio signal from a mobile device via a communications connector configured to electronically connect to a standard communications port on the mobile device; 
 generating, based on the video and audio signal received from the mobile device, an HDMI video and audio signal; and 
 generating, based on the HDMI video and audio signal, a wireless network transmission signal; and 
 
 by a first RF transceiver:
 communicating the wireless network transmission signal wirelessly to a second RF transceiver via a first antenna and without retransmission by additional wireless networking devices; and 
 
   at a receiver device preconfigured for operation with the transmitter device:
 by at least the second RF transceiver:
 receiving the wireless network transmission signal from the first RF transceiver via a second antenna; and 
 communicating the wireless network transmission signal to the second one or more video and audio signal processors; and 
 
 by at least the second one or more video and audio signal processors preconfigured to provide communications with the first one or more video and audio signal processors:
 receiving the wireless network transmission signal from the second RF transceiver; 
 generating, based on the wireless network transmission signal, the HDMI video and audio signal; and 
 outputting the HDMI video and audio signal to a display screen via an HDMI output connector configured to electronically connect to an HDMI input port on the display screen. 
 
   
     
     
         5 . The method according to  claim 4 , wherein the mobile device comprises at least one of: a tablet computing device or a smartphone computing device. 
     
     
         6 . The method according to  claim 5 , wherein the display screen comprises at least one of: a monitor, a television, or a projector. 
     
     
         7 . The method according to  claim 6 , wherein the transmitter device further comprises a first housing configured to house the first video and audio signal processor, the first antenna, and the first RF transceiver. 
     
     
         8 . The method according to  claim 7 , wherein the receiver device further comprises a second housing configured to house the second video and audio signal processor, the second antenna, and the second RF transceiver. 
     
     
         9 . The method according to  claim 7 , wherein the receiver device is integrated into the display screen.
