摘要： 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.

摘要： 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.

摘要： 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.

摘要： A class-D amplifier with multiple “nested” levels of feedback. The class-D amplifier surrounds an inner feedback loop, which takes the output of a switching amplifier and corrects for errors generated across the switching amplifier, with additional feedback loops that also take the output of the switching amplifier.

摘要： An audio processor has a number of ports that are configurable as input or output ports. Each port includes a jack, an input audio circuit and an output audio circuit. A switch is controllable to selectively connect an output of the output audio circuit to the jack when the port is configured as an output port. In one embodiment, the switch is bypassed with resistor and the output of the output audio circuit is coupled through the resistor to the jack when the port is configured as an input port.

摘要： Acoustic microphone array systems including arrays of microphones placed on a printed circuit board or other substrate in asymmetric patterns. A plurality of additional non-microphone components also reside on the board. The asymmetric placement of the microphones in the array provides flexibility in physically accommodating the additional non-microphone components.

摘要： An acoustic waveguide in accordance with one or more embodiments of the present technology that comprises a housing having a proximal end with an inlet aperture and a distal end with an outlet aperture, and a mounting flange positioned at the proximal end and configured to acoustically couple a driver to inlet aperture. A plurality of sound channels extend through the housing and acoustically couple the inlet aperture to the outlet aperture. Each sound channel at least partially defining a sound path has an acoustic length, wherein at least one of the sound paths of the plurality of sound channels has a bend angle that exceeds 180 degrees.

摘要： An amplifier having one or more channels where each channel includes a two half bridges (a master and slave sub-channel). The sub-channels can be connected either in parallel or in a full-bridge configuration via internal switches that route signals to a pair of speaker jacks. One switch in the amplifier has a first position that selectively connects the outputs of the master and slave sub-channel to the same input of the speaker load so that the two sub-channels will drive the speaker load in parallel and a second position where the output of the slave sub-channel is connected to another input of the speaker load so that the master sub-channel and the slave sub-channel will drive the speaker load in a Full-bridge configuration. A second switch has a first position that connects a second input of the speaker load to ground or reference potential of the sub-channels when the speaker load is to be driven in parallel and a second position that is a No-connect position that is used when the speaker load is driven in the Full-bridge configuration and a ground potential is not to be connected to the speaker.
