Aspects of the embodiments relate to audio systems, and more specifically to systems, methods, and modes for enhancing security in use of a bi-directional communications device that includes one or more speakers and one or more microphones.
Currently available audio systems either do not have bi-directional voice communications capabilities, or, if they do, lack security features to prevent unwanted and/or unauthorized visitors from listening in and/or participating in such conversations.
In addition, such devices are often packaged in unwieldly form factors that need to be located on a desk surface, taking up valuable surface area. In addition, such devices, even if they are packaged attractively, and contain advanced and sophisticated acoustical/audio processing devices and technology, are not located in an optimal location.
Many, if not all of the audio devices currently available, lack sophisticated networking interconnections such that managing such devices can be labor intensive. For example, if a software update needs to be implemented, then such updates may need to be implemented manually, which takes an inordinate amount of time and money.
Finally, many such devices, if they are capable of being interconnected to a network, lack true interoperability. That is, such devices cannot be treated as one of a group of devices that work together and can be managed in a much more efficient and effective manner, and which will work together to make distributed conversations and communications easier.
Accordingly, a need has arisen for systems, methods, and modes for enhancing security in use of a bi-directional communications device that includes one or more speakers and one or more microphones, to systems, methods, and modes for mounting such a device to a wall or other horizontal surface, to systems, methods, and modes for connecting and managing such a device through one or more proprietary networks including cloud based networks, and to systems, methods, and modes for interconnecting such devices through one or more proprietary networks so that management and control of such devices can occur.
It is an object of the embodiments to substantially solve at least the problems and/or disadvantages discussed above, and to provide at least one or more of the advantages described below.
It is therefore a general aspect of the embodiments to provide systems, methods, and modes for enhancing security in use of a bi-directional communications device that includes one or more speakers and one or more microphones, to systems, methods, and modes for mounting such a device to a wall or other horizontal surface, to systems, methods, and modes for connecting and managing such a device through one or more proprietary networks including cloud based networks, and to systems, methods, and modes for interconnecting such devices through one or more proprietary networks so that management and control of such devices can occur that will obviate or minimize problems of the type previously described.

One or more of the LAN and WAN can also be included in, incorporated with, or connected to the Internet, and such networks can be accessible via many different means such as fiber optic/cable systems, cellular systems, satellite systems, and the like.
According to further aspects of the embodiments, the operation of substantially if not all of the devices/components that make up soundbar 100, listed above, are either known to those of skill in the art, and/or are not needed to understand the aspects of the embodiments, and/or are beyond the scope of this discussion; therefore, in fulfillment of the dual purposes of clarity and brevity, a detailed discussion of the components of soundbar 100 have been omitted from herein.
According to further aspects of the embodiments, soundbar 100 device can be implemented as a web conferencing soundbar 100 with integrated camera. Sound bar 100 device can include a wide-angle, 110° field-of-view camera (e.g., video camera 124), high quality speakers (speakers 134), a far-field microphone array (mic pods 140a,b), echo cancellation signal processing, ambient noise reduction signal processing, Bluetooth® and USB connectivity, and HDMI algorithms. Echo cancellation and ambient noise reduction can facilitate the elimination of distracting background noises.
According to further aspects of the embodiments, soundbar 100 includes HDMI, USB and Bluetooth® connectivity to support “Bring Your Own Device” (BYOD) environments as well as integration with other audio devices for an enhanced and intuitive room collaboration experience. Consumer Electronics Control (CEC) display controls can turn the display on or off in response to triggers. Sound bar 100 device's dedicated audio inputs and outputs can be used to integrate additional technology such as hearing-enhanced systems. According to aspects of the embodiments, soundbar 100 incorporates BT connected audio.
According to aspects of the embodiments display 304 utilizes either an LED display, or LCD that is typically not visible unless it is displaying something. Other display technologies can also be used, and the number of digits can vary as well.
According to aspects of the embodiments, use of rolling security code apparatus 300 enables secure use of soundbar 100 by allowing only those present in room 200 at the time of a meeting to access soundbar 100. This discussion presumes only for the non-limiting purpose of this discussion that an intended use of soundbar 100 is for secure meetings; however, such intended use is not to be taken in a limiting manner, and is intended only as an example of a one of many uses only; that is, a person employed by an Enterprise that owns soundbar 100, or the person(s) that have one in their personal residence are, of course, free to use soundbar 100 in a manner consistent with the discussion herein, or in any manner that they see fit.
As discussed above, rolling security code apparatus 300 includes RNG 302, display 304, and rolling code App 306. Rolling security code apparatus 300 operates in the following manner. RNG 302 substantially continuously but periodically generates an N-digit code that is transmitted periodically to processor 118. Processor 118 performs at least two operations with the received N-digit code. First, it displays the same on M-digit display 304. Note that M is equal to or greater than N; otherwise, the entire N-digit code could not be displayed; having an “M” bit display wherein M>N allows room for growth should additional security be needed. The second thing processor 118 does with the N-digit code is to forward the N-digit code to rolling code App 306 that resides in memory accessible and processed by processor 118 according to aspects of the embodiments.
BT communications App 312 also resides in memory that is accessible and processed by processor 118. BT communications App 312 enables BT communications, and processor 118 also accesses many other applications that perform functions associated with soundbar 100. According to further aspects of the embodiments, rolling code App 306 interfaces with BT communications App 312 to allow previously unknown users the ability to communicate with soundbar 100.
According to aspects of the embodiments, rolling code App 306 receives the periodically generated and received N-digit code from RNG 302. Rolling code App 306 stores the N-digit code for a pre-determined period of time, and when a new one is received, it writes over the old N-digit code with the new one. Rolling code App 306 interfaces with BT communications App 312. BT communications App 312 uses BT transceiver 112 to substantially constantly transmit the identity of soundbar 100 via BT transmissions, and listening for responses. According to further aspects of the embodiments, soundbar 100 can use such substantially constant BT transmissions to find new users of soundbar 100 or can use PIR detector 152 to detect new users, and only then facilitate communications from BT transceiver 112 and BT communications App 312. As those of skill in the art can appreciate, a BT transmission from BT transceiver 112 and BT communications App 312 includes an identifier of the device that is transmitting the BT communications, in this case soundbar 100. Such identifier can include an alphanumeric code, such as “CRSTN_SNDBR_236791,” wherein “CRSTN” can represent the manufacturer of soundbar 100, Crestron Electronics, Inc., of Rockleigh N.J. “SNDBR” can represent the particular device, in this case a soundbar 100 device, and the last “n” digits can be a unique identifier, such as a serial number (ID). Such identifiers can comprise alpha-only characters, numeric-only characters or other combinations as well.
According to further aspects of the embodiments, rolling code App 306 can maintain a list of currently connected PEDs 308. Rolling code App 306 can periodically check the currently connected PEDs 308 to verify their presence in the room within which the meeting is being held. If for some reason a PED 308 is shut off (e.g., dead battery), or the person using PED 308 leaves the meeting, rolling code App 306 can terminate communications with that particular PED 308 in order to further enhance security of communications with soundbar 100.
Once a user receives the BT transmitted soundbar 100 identifier on PED 308, the user has a predetermined amount of time to enter the N-digit code in the “password” section of the BT response back to soundbar 100, as is known to those of skill in the art. In place of the password, however, the continuously changing N-digit code would be used. The N-digit code would only be available to those located within room 200 according to aspects of the embodiments, as only those people/users 204 would be able to see the N-digit code on N-digit display 304. According to further aspects of the embodiments, the N-digit code can be used to encode substantially all transmissions to and from PED 308 using the N-digit code as an encoding or encryption key in all BT transmissions between soundbar 100 and PED 308 and the user.
Once the user enters the N-digit code into the password section of the BT communications enablement application, and transmits it to soundbar 100, BT transceiver 112 receives the communication and forwards it to rolling code App 306. BT transceiver 112 recognizes the communication from PED 308a as being a “join meeting” communication as it is the first communication from this device, and it is formatted in a unique manner. The communication from PED 308 also contains a unique identifier (phone number, or other identification number) of PED 308a, and forwards that information to rolling code App 306. Rolling code App 306 receives the transmitted message from PED 308a, and checks the N-digit code in the communication from 308a to the N-digit code stored and displayed. If the two match, then rolling code 308a sends a confirmation message to both PED 308a and processor 118 that this particular PED 308a can participate in the current or soon to be started meeting.
According to further aspects of the embodiments, soundbar 100, rolling code App 306, BT communications App 312 perform this logon/secure communications process for any PED that attempts to join the current or soon to start meeting. According to further aspects of the embodiments, rolling code App 306 can periodically check all of the previously registered PEDs 308 from time to time to verify they are still in the vicinity during the current meeting, using one or more additional communication confirmation messages. According to further aspects of the embodiments, rolling code App 306 can incorporate a hard time out, meaning that unless a manual override is performed, all BT communications will cease. Such hard time out can be preceded by a message to an organizer of the meeting (the person that set up the meeting). In addition, other time outs can include soft time outs, that would occur based on a predicted meeting duration, or a communication from a meeting set-up Application that would include a duration extracted automatically from meeting set-up software parameters.
Described above is a system and method for providing secure communications between participants in a meeting that includes a soundbar 100, and these communications have been described as occurring using BT technology. According to aspects of the embodiments, the systems and methods are not limited thereto, and can include near field communications (NFC) devices/applications, WiFi devices/applications, infra-red communications devices and related applications, among other types of communications technologies.
Soundbar 100 can detect a new user in the room in which it is located, either through PIR detector 152, BT lookup in regard to a mobile device that the person might be carrying, or other means. The detection sensitivity of the PIR detection device can be programmable. Once detection by one or more means has been accomplished, soundbar 100 can use that to trigger a random number generator that generates a four-digit pairing code. The four-digit pairing code can then be displayed for a predetermined amount of time to allow the user to pair the mobile device to soundbar 100. Such mobile devices are not just limited to cellular phones but can also be personal digital assistant (PDAs) devices, laptop computers, among other devices. The four digit pairing code (the number of digits could be different if BT and other communication technologies required them to be different) can only be used by one device; once the device is paired, or the time for pairing expires, a new pairing code can be generated if other people/devices are determined to be within the room that soundbar 100 is located.
According to further aspects of the embodiments, once the call is complete, or lost, the code automatically changes after a predefined amount of time and the previous code is no longer available to connect. According to aspects of the embodiments, use of rolling codes with soundbar 100 substantially prevents random connections to soundbar 100, by either previously connected people or unauthorized people, while walking by a conference room with a soundbar 100 in it; the users of soundbar 100 are thereby relatively assured of the privacy of their electronic and audio communications.
According to aspects of the embodiments, BT pairing occurs through conventional BT pairing processes on smartphones and other BT communication capable devices. As those of skill in the art can appreciate, such “smart” devices typically are always “sniffing” electronically for BT devices to pair with, and if the settings page were monitored it can be seen that numerous devices are being interrogated almost constantly. The user needs to enter the code, however, to enable the pairing process.
Method 400 begins with method step 402 in which soundbar 100 and rolling security code apparatus 300 substantially continuously but periodically generates an N-digit random number and displays the same on M-digit display 304 (in which M is greater than or equal to N) and stores the same for later processing.
In method step 404, soundbar 100 and rolling security code apparatus 300 substantially continuously but periodically transmit a join meeting communication into room 200 via BT transceiver and BT communications App 312. The join meeting communication contains an identifier of soundbar 100. Method 400 and soundbar 100 and rolling security code apparatus 300 continually transmit the join meeting communication on a periodic basis, waiting for a response from a user with a BT enabled PED 308.
According to further aspects of the embodiments, soundbar 100 and rolling security code apparatus 300 do not necessarily substantially continuously but periodically transmit the join meeting communication into room 200. That is, soundbar 100 and rolling security code apparatus 300 can transmit the join meeting communication in the manner described above for a first period of time, by way of non-limiting example, for the first 5-10 minutes after the meeting has started. Once the first time period has passed, soundbar 100 and rolling security code apparatus 300 can clear display 304 so that no N-digit random number is displayed, further enhancing security. At this point, soundbar 100 and rolling security code apparatus 300 can presume that all of the attendees have arrived and not accept any further requests to join the meeting.
Soundbar 100 and rolling security code apparatus 300 can obtain the meeting start time from the meeting software/application automatically, or the organizer can alert soundbar 100 and rolling security code apparatus 300 as to when the meeting starts, especially if the meeting does not start on time. According to further aspects of the embodiments, once the first period of time has passed, soundbar 100 and rolling security code apparatus 300 can use PIR detector 152 to provide an alert as to the presence of a new use or meeting attendee. According to still further aspects of the embodiments, soundbar 100 and rolling security code apparatus 300 can seek clearance from the meeting organizer as to whether or not to send a join meeting communication and/or display a new code.
In method step 406, soundbar 100 and rolling security code apparatus 300 receives a first request to join meeting BT communication from a first BT enabled PED 308a operated by a first user. The first request to join meeting BT communication from PED 308a includes a unique identifier of PED 308a, as well as the N-digit random number that was previously displayed for the user to see and enter into their PED 308a when responding to the request to join meeting communication. The operation of entering the N-digit random number that is being displayed by display 304 is similar to the operation of entering a password to a BT transmitting device in one's home, but is not static, as the N-digit random number changes from time to time. The period of changing the N-digit random number is programmable, and can be practically any value, but typically might be two minutes, three minutes, or some similar duration. The duration itself can change periodically, meaning a first N-digit random number could be displayed and usable for two minute and then the next, second N-digit random number could be displayed and usable for three minutes, and so on. According to aspects of the embodiments, changing the N-digit random number sign-on code provides enhanced security as this substantially prevents snooping and eavesdropping by unauthorized personnel.
Following method step 406, method 400 proceeds to decision step 408, in which the value of the N-digit random number (if there is one) in the first request to join meeting BT communication is compared by soundbar 100 and rolling security code apparatus 300 to the N-digit random number that was previously stored and displayed; as those of skill in the art can no doubt appreciate, it is entirely possible that by the time a user enters the displayed N-digit random number, a new one can already have been generated and displayed; according to aspects of the embodiments, soundbar 100 and rolling security code apparatus 300 and method 400 can permit one or more previously displayed N-digit random numbers to be entered and allow the user to join. Or, according to further aspects of the embodiments, such permission can extend only for a short period of time (changeable) following the generation of the new N-digit random number. For example, if a first N-digit random number has been generated and displayed, and the first user sees it and enters it into her PED 308a, but prior to transmission a new N-digit random number is generated and displayed, soundbar 100 and rolling security code apparatus 300 can allow the previous N-digit random number to be used for perhaps 30 seconds, or some other programmable period of time. The period of time used in this non-limiting example is meant to be exemplary only, and not to be taken in a limiting manner.
If the N-digit random number contained in the request to join communication matches the stored N-digit random number (“Yes” path from decision step 408, then method 400 proceed to step 410, in which soundbar 100 is permitted to establish communications with the first PED 308a.
If the N-digit random number contained in the request to join communication does not match the stored N-digit random number (“No” path from decision step 408, then method 400 proceed to step 412, in which soundbar 100 is not permitted to establish communications with the first PED 308a. Method 400 repeats for as long as the meeting is held, or according to previously determined time limits in the manner as discussed above.
According to aspects of the embodiments, soundbar 100 can be connected to a network, such as the internet, and through the internet to the Cloud. As such, soundbar 100 can be provisioned, managed and configured through the Cloud. For example, and according to further aspects of the embodiments, BT codes as discussed above in regard to the Rolling Security Code feature can be managed via the XiO Cloud. According to still further aspects of the embodiments, a dashboard can be implemented that displays the status of soundbar 100.
According to aspects of the embodiments, soundbar 100 implements an audio video bridging (AVB) type network, which implements a set of protocols being developed by the IEEE 802.1 Audio/Video Bridging Task Group. According to aspects of the embodiments, there are at least four primary differences between the proposed architecture and existing 802 architectures: Precise synchronization, Traffic shaping for media streams, admission controls, and Identification of non-participating devices.
According to further aspects of the embodiments, soundbar 100 can be referred to as a USB audio device that works together with other devices, such as a PC, among others, all of which interface to soundbar 100 using the USB port. The soundbar 100 also incorporates at least one, two, or more Ethernet ports to connect to external microphone Pods.
In addition, soundbar 100 provides a standard Ethernet port and Remote Network Device Interface Specification (RNDIS) port. As those of skill in the art can appreciate, the latter is essentially a port that uses an Ethernet protocol on USB interface to connect to a PC and/or other systems (e.g. XIO server) for system management and/or firmware updates, among other uses.
According to further aspects of the embodiments, soundbar 100 can communicate with other devices as a peripheral audio device (i.e. microphone and speaker), and USB camera, and this interface can use standard USB interface.
According to further aspects of the embodiments, soundbar 100 can communicate with other devices as a microphone Pod, and in this case, the communications occur as a networked audio device, and this interface can use LAN power-over-Ethernet (PoE) connection. According to aspects of the embodiments, one non-limiting example of an audio network communications system and protocol is Dante. Such systems and communication protocols can also be referred to as audio-over-internet protocols (IP), or audio-over-Ethernet.
According to further aspects of the embodiments, soundbar 100 can communicate with other devices to receive system configuration, program, or firmware updates, and this interface can use LAN and/or USB connection (via RNDIS).
According to further aspects of the embodiments, soundbar 100 can communicate with other devices for system management and routing of “join” messages, including proprietary software symbols, and this interface can use a LAN connection.
