Abstract: A conferencing system may position a sensor array in a meeting space and detect, with the sensor array, an activity of a participant present in the meeting space. A computing device connected to the sensor array may assign at least one identifier to describe the activity prior to characterizing the at least one identifier as a behavioral context. In response to the behavioral context, the computing device may alter at least one operational parameter of the sensor array.

Abstract: Described are techniques for video bridging for conversion of IP network video streams to the USB Video Class (UVC). The conversion of IP video to UVC video can include the use of software-only conversions and hardware assisted conversions, and can be done within purpose-built “conversion” devices or as software only solutions operating within applications or drivers within the operating systems of the “end nodes”. The end-nodes simultaneously see and use multiple USB UVC video sources. The conversion process can also convert the USB UVC video control protocol to IP Video Stream control protocols.

Abstract: Technology is disclosed for establishing and administering multiple virtual machines, each with an audio, video and control (AVC) operating system (OS). The technology can also establish and administer cloud based AVC OSs. A server implementing this technology can perform real-time AVC processing, alongside soft and non-real-time processing and can host multiple, independent, virtual AVC OSs. Each AVC OS can perform the processing for an AVC setup. Each of the AVC OSs can be operated by a corresponding virtual machine controlled by a hypervisor running on the server. A cloud based AVC OS can perform processing for a corresponding remote AVC setup comprising multiple AVC devices. An AVC routing system can cause AVC signals from a particular AVC setup to reach a corresponding cloud AVC OS and conversely can cause signals from an AVC OS to reach the correct destination device.

The method further includes parameterizing the group selection such that the group selection dynamically adjusts to include the prominent participants within the field of view of the camera. The method further includes tracking, via a camera, the parameterized group selection.

Abstract: A conferencing system may connect a processing unit to a camera and a microphone in a meeting room. A calibration module of the processing unit may generate a calibration strategy prior to obtaining video data from the camera, with the processing unit, in accordance with the calibration strategy. The processing unit may then translate the video data into spatial data that is utilized by a mapping module of the processing unit to identify a physical location of the microphone in the meeting room. The calibration module may determine a field of view operating parameter of the camera in response to the spatial data.

Abstract: Disclosed herein is a data encryption technique that pertains to a data stream that divides into data samples. Each sample is truncated by a predetermined number of bits to make room in the data stream for an encryption data packet. The truncation reduces the resolution of the data in exchange for security features. The encryption data packet includes a counter to prevent replay attacks and an HMAC to verify contents and synchronize the frames of the data stream. The data is encrypted and transmitted to a receiver where the data is played.
