Abstract: A method may include identifying, in a frame of a video feed, a region of interest (ROI) and a background, encoding the background using a first quantization parameter to obtain an encoded low-quality background, encoding the ROI using a second quantization parameter to obtain an encoded high-quality ROI, and encoding location information of the ROI to obtain encoded location information. The method may further include combining the encoded low-quality background, the encoded high-quality ROI, and the encoded location information to obtain a combined package. The method may further include transmitting the combined package to a remote endpoint.

Abstract: A system is provided for automated configuration of a connection interface between a headset device (e.g., a headset base) and a telephone (e.g., desktop phone). The system includes configuration circuitry designed to automatically perform a sequential analysis of multiple interface configuration options for the connection interface between the headset device and telephone. The analysis of each respective interface configuration option includes (a) accessing stored configuration information defining predefined switch positions for an array of controllable switches (e.g., optical switches) corresponding with the respective interface configuration option, (b) set the array of switches to the predefined switch positions specified by the accessed configuration information, and (c) performing a signal analysis to analyze electrical signals on the connection interface.

Abstract: Correcting encode bit rate errors developed by a hardware encoder with an outer software rate adjustment loop. The rate adjustment loop maintains a VBV (video buffering verifier) buffer model. When VBV buffer fullness is over a threshold, the rate adjustment loop drops frames. If below the threshold, periodically a rate adjustment analysis performed. If a number of frames above a threshold have been dropped, the hardware encoder bit rate is decreased. A leaky bucket is checked to determine in bits and out bits. If the number of in bits exceeds the number of out bits times a multiplier, the hardware encoder bit rate is decreased. If the number of in bits times a multiplier is less than the number of out bits, the hardware encoder bit rate is increased. Dropping frames on buffer condition provides shorter term correction and adjustment of the hardware encoder bit rate provides longer term correction.

Abstract: A method for tracking movement of a presenter during a videoconference comprises tracking the location of subject of interest; quickly detecting error conditions—such as can occur when a subject of interest moves too quickly or when a subject of interest walks past another person—and quickly reinitiating the tracking sequence to help ensure a positive videoconferencing experience.

Abstract: A method for hybrid noise suppression involves receiving a first processed audio signal and a second processed audio signal from an audio device. The first processed audio signal results from a comprehensive audio processing including a noise spectrum estimate-based noise suppression performed on a noisy audio input signal obtained by the audio device. The second processed signal results from a partial audio processing excluding the noise spectrum estimate-based noise suppression performed on the noisy audio input signal. The method further involves temporally aligning the second processed audio signal with the first processed audio signal, predicting a noise suppression parameter using a neural network model operating on the second processed audio signal after the temporal alignment, generating a noise-suppressed audio output signal from the first processed audio signal after the temporal alignment using the noise suppression parameter, and outputting the noise-suppressed audio output signal.

Generating the VE value includes adjusting the VE value based upon a delay between two of the microphones. The VAD circuit is configured to provide the VE value to the separated source processor.
