摘要： A videoconferencing device at an endpoint determines whether a person is a real person standing in front of a display device or if the person is instead an image rendered by a display device. In the first instance the real person will be included in a video feed for transmission to a remote endpoint. In the second instance, images of the display device on which the person is rendered will not be included in the video feed.

摘要： A method is disclosed for forking call audio channels. The method includes, during an active call, receiving a first audio stream of first call audio that originates from a far-end telephony device, and receiving a second audio stream of second call audio that originates from a microphone of a near-end headset. Further, the method includes generating, during the active call, a third audio stream containing the first call audio by processing the first audio stream, and generating a fourth audio stream containing the second call audio by processing the second audio stream. Still yet, the method includes, during the active call, generating a fifth audio stream containing the first call audio, and generating a sixth audio stream containing the second call audio.

摘要： Systems and methods are provided for managing multiple wireless links, e.g., between base stations and wireless headsets. Each wireless link communicates data packets (e.g., audio data packets) according to a wireless protocol (e.g., Bluetooth) defining a series of connection intervals having a defined number of frames (e.g., Bluetooth eSCO intervals including 6 or 12 frames per interval). A controller stores interval segmentation data specifying a first interval segment (including a first subset of frames) allocated to original transmissions of packets and at least one additional interval segment (including additional subsets of frames) allocated to retransmissions of failed packets. The controller uses the interval segmentation data to manage timing for packet transmissions and retransmissions by the various wireless devices, such that each device (a) sends transmissions only during the first interval segment and (b) sends retransmissions only during the additional interval segment(s), to thereby reduce interference between the various wireless links.

摘要： A method for interrupt based pairing for wireless audio devices includes determining a colocation of a wireless audio device with a subsequent wireless audio device with one or more sensors. An interrupt is generated in response to determining the colocation. A pairing mode of the wireless audio device is enabled in response to the interrupt. The wireless audio device is paired with the subsequent wireless audio device.

摘要： Methods and apparatuses for carrier selection are described. In one example, a method of carrier selection for a frequency-hopping wireless communication device includes using a fixed set of available carriers to hop over during communications. The method includes allocating a subset of the available carriers to a long-range carrier class. In one example, the subset of available carriers consists of at least two carrier clusters spaced widely in the frequency spectrum. The method further includes monitoring a transmit power level in the wireless communication device. The method further includes using the long-range carrier class to hop over during communications if the wireless communication device transmit power is greater than a predetermined level.

摘要： A communication headset includes a neckband with a horseshoe-shaped footprint and two microphone tips disposed at two ends of the neckband, the two ends establishing an aperture of the horseshoe-shaped footprint. Each of the two microphone tips includes a slanted base. The communication headset further includes a microphone array including two sets of microphones in a spatial configuration in which the two sets of microphones are disposed on the slanted bases of the two microphone tips. An effective acoustic spacing between the microphones in the microphone array is at least 15 mm

摘要： A method of presenting a soundscape in an environment space using a plurality of controllable speakers arranged the space is provided. A spatial audio engine may access a spatial audio file defining a digital representation of the soundscape, including (a) a plurality of sound elements to be output in the space over time, (b) sound playback location information defining location(s) for each sound element to be output, and (c) timing information defining time(s) for each sound element to be output. The spatial audio engine may also access speaker location information for each speaker in the space. For each sound element to be played in the space over time, the spatial audio engine may correlate the sound playback location information with the speaker location information to identify one or more of the speakers to be controlled to output audio signals associated with the respective sound element.
