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.

Claims

1. A system for wirelessly mirroring video from a mobile device to a display screen, the system comprising:

a mobile device dongle, the mobile device dongle comprising;

a non-USB display and audio port connector configured to electronically connect to a non-HDMI-type display and audio port on the mobile device,

wherein the mobile device is a smartphone or tablet computer;

a mobile video translator, the mobile video translator electronically connected to the audio and display port connector, and configured to;

receive a mirrored, full screen, non-HDMI uncompressed video and audio signal from the mobile device through the display and audio port on the mobile device,

process and translate the mirrored, full screen, non-HDMI uncompressed video and audio signal into an HDMI video and audio signal, and

output, based on the received mirrored, full screen, non-HDMI uncompressed video and audio signal, the HDMI video and audio signal;

a first video network processor electronically connected to the mobile video translator, preconfigured to communicate solely with a second video network processor to the exclusion of other video network processors, and configured to;

receive the HDMI video and audio signal from the mobile video translator,

process and translate the HDMI video and audio signal into a wireless network transmission signal, and

output, based on the received HDMI video and audio signal, the wireless network transmission signal;

a first plurality of antennas;

a first RF transceiver, the RF transceiver electronically connected to the first video network processor and to the first plurality of antennas, the first RF transceiver configured to communicate the wireless network transmission signal wirelessly to a second RF transceiver over at least one of the plurality of antennas and without retransmission by additional wireless networking devices;

a rechargeable battery; and

a power control module electronically connected to the rechargeable battery, the power control module providing power to the mobile video translator, the first video network processor, and the first RF transceiver, the power control module configured to;

when an external power source is supplied, provide power based on the external power source and charge the rechargeable battery, and

when no external power source is supplied, provide power based on the rechargeable battery so as to power the mobile device dongle; and

a display screen dongle, the display screen dongle preconfigured for operation solely with the mobile device dongle, the display screen dongle comprising;

a second plurality of antennas;

an HDMI output connector configured to electronically connect to an HDMI input port on the display screen,

the second RF transceiver, the second RF transceiver electronically connected to the second video network processor and to the second plurality of antennas, the second RF transceiver configured to receive the wireless network transmission signal from the first RF transceiver via at least one of the second plurality of antennas, and communicate the wireless network transmission signal to the second video network processor;

the second video network processor electronically connected to the HDMI output connector, preconfigured to communicate with the first video network processor to the exclusion of other video network processors, and configured to;

receive the wireless network transmission signal from the second RF transceiver,

process and translate the wireless network transmission signal into the HDMI video and audio signal, and

output, based on the received wireless network transmission signal, the HDMI video and audio signal to the HDMI output connector for display on the display screen,

wherein the first and second video network processors are preconfigured to initiate communications with one another in response to being powered on and without input by a user of system.

2. A system for wirelessly mirroring video from a mobile device to a display screen, the system comprising:

a video source device comprising;

a non-USB communications connector configured to electronically connect to a non-HDMI-type communications port on a mobile device;

a mobile video translator, the mobile video translator electronically connected to the non-USB communications connector, and configured to;

receive a non-HDMI video and audio signal from the mobile device through the non-HDMI-type communications port on the mobile device,

process and translate the non-HDMI video and audio signal into an HDMI video and audio signal, and

output the HDMI video and audio signal;

a first video network processor electronically connected to the mobile video translator, preconfigured to communicate with a second video network processor to the exclusion of other video network processors, and configured to;

receive the HDMI video and audio signal from the mobile video translator,

process and translate the HDMI video and audio signal into a wireless network transmission signal, and

output, based on the received HDMI video and audio signal, the wireless network transmission signal;

a first plurality of antennas; and

a first RF transceiver, the RF transceiver electronically connected to the first video network processor and to the first plurality of antennas, the first RF transceiver configured to communicate the wireless network transmission signal wirelessly to a second RF transceiver over at least one of the plurality of antennas and without retransmission by additional wireless networking devices; and

a video receiver device preconfigured for operation with the video source device, the video receiver device comprising;

a second plurality of antennas;

an HDMI output connector configured to electronically connect to an HDMI input port on a display screen,

the second RF transceiver, the second RF transceiver electronically connected to the second video network processor and to the second plurality of antennas, the second RF transceiver configured to receive the wireless network transmission signal from the first RF transceiver via at least one of the second plurality of antennas, and communicate the wireless network transmission signal to the second video network processor;

the second video network processor electronically connected to the HDMI output connector, preconfigured to communicate with the first video network processor to the exclusion of other video network processors, and configured to;

receive the wireless network transmission signal from the second RF transceiver,

process and translate the wireless network transmission signal into the HDMI video and audio signal, and

output, based on the received wireless network transmission signal, the HDMI video and audio signal to the HDMI output connector for display on the display screen,

wherein the first and second video network processors are preconfigured to initiate communications with one another in response to being powered on.

3. The system according to claim 2 comprises a mobile handheld device.
