Abstract

A secure conferencing device operating in a host or a guest mode. In host mode, the secure conferencing device coupled to an interactive digital signage (IDS) device, grants conference control to a host computer of the IDS device. The secure conferencing device receives a guest control signal and a guest video stream from a guest device, where the secure conferencing device prevents the guest control signal from being communicated to the host computer, yet transmits the guest video stream to the host computer for display on the IDS device. In the guest mode, the secure conferencing device grants conference control to a guest device, enables the guest device to affect a component of the IDS device, but does not enable the guest device to communicate guest control signals to the host computer of the IDS device.

First claim

What is claimed is:

1. An electronic secure conferencing device comprising:
a firewall component;
a microphone; and
one or more processors coupled to the firewall component and to the microphone, wherein the one or more processors are configured to:
transmit a host mode signal to an interactive digital signage (IDS) device granting conference control to a host computer of the IDS device;
based at least on the host mode signal, configure the firewall component to enable communications between the one or more processors and the host computer;
receive data via a universal serial bus (USB) cable, wherein the data comprises a guest control signal and a guest video stream, and wherein the firewall component prevents the guest control signal from being communicated to the host computer;
receive a first audio signal from the microphone;
transmit, via the firewall component, the first audio signal to the host computer; and
transmit the guest video stream to the host computer, wherein first video images of the guest video stream are displayed on the IDS device.

2. The electronic secure conferencing device of claim 1 , wherein to transmit the host mode signal, the one or more processors are configured to:
transmit, via a single cable, the host mode signal to the IDS device, wherein the single cable is capable of transmitting video, audio, and control data.

3. The electronic secure conferencing device of claim 1 , further comprising:
a cable retainer that interlocks with a portion of the USB cable from which the guest video stream is received, wherein the cable retainer is affixed to the electronic secure conferencing device, and wherein the cable retainer and an exterior of the electronic secure conferencing device appear as a uniform surface.

4. The electronic secure conferencing device of claim 1 , further comprising:
one or more sets of visual indicators located on a perimeter of the electronic secure conferencing device coupled to the one or more processors, wherein the one or more processors are configured to:
determine a first quality of the first audio signal; and
based at least on the first quality, transmit a signal to a first set of visual indicators of the one or more sets of visual indicators, wherein the first set of visual indicators corresponds to the first quality, and wherein the first set of visual indicators are in closer proximity to a direction in which the first audio signal is received compared to the one or more remaining sets of visual indicators.

5. The electronic secure conferencing device of claim 4 , wherein the one or more processors are configured to:
receive a remote signal from the IDS device, wherein the remote signal corresponds to the first video images or the first audio signal received by a remote meeting participant, and wherein one or more visual indicators of the first set of visual indicators corresponds to a second quality of the remote signal.

6. The electronic secure conferencing device of claim 1 , further comprising:
a speaker positioned a distance from the microphone, wherein output from the speaker is directed away from the microphone, wherein the speaker is coupled to the one or more processors, and wherein the one or more processors are configured to:
receive, via the firewall component, a second audio signal from the host computer; and
output, via the speaker, the second audio signal, wherein the second audio signal travels in a direction away from the microphone.

7. The electronic secure conferencing device of claim 1 , wherein the one or more processors are further configured to:
transmit a guest mode signal to the IDS device granting conference control to a guest device coupled to the electronic secure conferencing device;
based at least on the guest mode signal, configure the firewall component to enable communications between the guest device and the one or more processors, and between the one or more processors and the IDS device;
receive a second audio signal from the microphone; and
transmit, via the firewall component, the second audio signal to the guest device.

8. The electronic secure conferencing device of claim 7 , wherein the one or more processors are further configured to:
receive, via the firewall component, a guest control signal from the guest device; and
transmit via the firewall component, the guest control signal to the IDS device, wherein the guest control signal affects a camera or a touchscreen of the IDS device.

9. The electronic secure conferencing device of claim 7 , wherein the one or more processors are further configured to:
receive second video images from the guest device; and
transmit the second video images to the IDS device, wherein the second video images are displayed on the IDS device.

10. An interactive digital signage (IDS) device comprising:
a firewall component;
a host computer; and
one or more processors coupled to the firewall component and the host computer, wherein the one or more processors are configured to:
receive a host mode signal granting conference control to the host computer;
based at least on the host mode signal, configure the firewall component to enable communications between an electronic secure conferencing device and the one or more processors, and between the one or more processors and the host computer;
receive, via the firewall component, a first audio signal from the electronic secure conferencing device;
transmit, via the firewall component, the first audio signal to the host computer;
in response to the transmission of the first audio signal, transmit, via the firewall component, a second audio signal from the host computer to the electronic secure conferencing device, wherein the second audio signal is output to a speaker of the electronic secure conferencing device;
receive a guest mode signal granting conference control to a guest device coupled to the electronic secure conferencing device; and
based at least on the guest mode signal, configure the firewall component to enable reception of guest control signals, wherein the firewall component prevents a guest control signal from being transmitted to the host computer.

11. The IDS device of claim 10 , wherein the one or more processors are further configured to:
receive a guest video stream from the electronic secure conferencing device;
enable transmission of the guest video stream to the host computer;
receive guest video images of the guest video stream from the host computer; and
display the guest video images on the IDS device.

12. The IDS device of claim 10 , wherein the one or more processors are configured to:
receive, via the firewall component, the guest control signal from the electronic secure conferencing device;
based on at least the guest control signal, affect a camera or a touchscreen of the IDS device, wherein the camera and the touchscreen are coupled to the one or more processors.

13. The IDS device of claim 10 , wherein the one or more processors are configured to:
receive guest video images from the electronic secure conferencing device; and
display the guest video images on the IDS device.

14. A method for a secure conferencing device comprising:
transmitting a host mode signal to an interactive digital signage (IDS) device granting conference control to a host computer of the IDS device;
based at least on the host mode signal, configuring a firewall component to enable communications between the secure conferencing device and the host computer;
receiving data via a universal serial bus (USB) cable, wherein the data comprises a guest control signal and a guest video stream, and
