Abstract: Disclosed are systems and methods for a frontend capture module of a video conferencing application, which can modify an input signal, received from a microphone device to match predetermined signal characteristics, such as voice signal level and expected noise floor. An Input stage, a suppression module and an output stage amplify the voice signal portion of the input signal and suppress the noise signal of input signal to predetermined ranges. The input stage selectively applies gains defined by a gain table, based on signal level of the input signal. The suppression module selectively applies a suppression gain to the input signal based on presence or absence of voice signal in the input signal. The output stage further amplifies the input signal in portions having a voice signal and applies a gain table to maintain a consistent noise floor.

The method also includes receiving a presence score determined from at least one of a comparison of the QR code to the image and a comparison of the sound signal to the sound clip.

Abstract: A system can automatically adjust a virtual background used by a participant in a video conference to match lighting level conditions present in a foreground of a participant video stream captured at a participant device. The matching can be done by adjusting one or more virtual background parameters, including but not limited to, exposure, brightness, contrast, and ISO. In some implementations, the system can dynamically or automatically adjust the lighting levels of the virtual background based on changes that may occur to the lighting level of the foreground during the video conference.

Abstract: One disclosed example involves a client device joining a videoconferencing meeting in which there is end-to-end encryption, where the end-to-end encryption is implemented by the client devices participating in the meting using a meeting key provided by the meeting host. Thereafter, the client device receives a public key of an asymmetric key pair corresponding to the host of the meeting, where the public key is different from the meeting key. The client device then generates a security code based on the public key and output the security code on a display device. The security code can be compared to another security code generated by another client device participating in the meeting to verify if the meeting is secure. The client device may also receive encrypted videoconferencing data, decrypt it using the meeting key, and output the decrypted videoconferencing data on the display device.
