    摘要: Systems and methods for bandwidth-limited video transport are configured to receive (or otherwise discern) a selection of video parameter limits that correspond to a bandwidth limit and apply the video parameter limits to an input video stream to enforce the bandwidth limit while preserving video quality. Methods may include adjusting the video stream one parameter at a time until the adjusted video stream meets the bandwidth limit. Parameters to be adjusted may include image resolution, frame rate, image compression, color depth, bits per pixel, and/or color encoding. In some embodiments, the image resolution is reduced first, the frame rate is reduced next, and the image compression is increased last. The extent and/or order of the adjustments of the parameters may be selected by the user, based on the content of the video stream, and/or based on the bandwidth limit.

    摘要: An example method of operation may include receiving audio data at one or more microphones disposed in a corresponding plurality of network devices, identifying amplitude values of the audio data at each of the plurality of network devices, and each of the amplitude values identified at each of the plurality of network devices are different from each other of the amplitude values, determining at each of the plurality of network devices a location of the audio data based on a direction and amplitude of the received audio data, modifying the audio data for output via a plurality of loudspeakers disposed in each of the plurality of network device, and outputting, via the plurality of loudspeakers, the modified audio data, and each loudspeaker outputs different versions of the modified audio data.

    摘要: An example method of operation includes identifying a loudspeaker array profile defining characteristics of a loudspeaker array stored in memory, identifying a three-dimensional venue geometry value stored in the memory, defining virtual receivers to simulate acoustic characteristics within the venue geometry, defining a number of passive acoustic filter permutations to perform within a range of passive acoustic filter settings, and each passive acoustic filter setting is unique and has one or more passive acoustic filters to apply to one or more loudspeakers in the loudspeaker array, selecting performance criteria to apply to the loudspeaker array to represent its sound coverage uniformity at a given location throughout the venue geometry, calculating the performance criteria of the loudspeaker array via a passive acoustic filter setting selected from one or more of the passive acoustic filter permutations by performing a simulation with the passive acoustic filter settings, identifying an optimized passive acoustic filter setting from a specific permutation, with which the loudspeaker array achieves optimal uniform sound coverage in the venue geometry, and applying the optimized passive acoustic filter setting to the loudspeaker array.

    摘要: An example process may include identifying an area of an environment to emit one or more sound masking signals, determining a noise level of one or more surrounding areas adjacent to the area, selecting one or more frequency ranges and respective amplitudes of the one or more sound masking signals to apply to the area based on the noise level, and emitting the masking signals via one or more emitters disposed in the area.
