Abstract: A method for context-dependent in-call video codec switching includes receiving an indication that a far-side endpoint includes a capability to switch from an initial video codec to a secondary video codec during a call. During a call with the far-side endpoint, the method includes determining that a performance of an encoder satisfies a codec switching threshold. The codec switching threshold indicates that the performance of the encoder justifies switching from the initial video codec mid-stream of the call. During a call with the far-side endpoint, the method also includes switching from the initial video codec initially negotiated to govern the call to the secondary video codec.

Abstract: Systems and methods of the present disclosure are directed to automatic control of mute controllers for participants in videoconferences. For example, a method for automatically controlling a mute control associated with a participant during a videoconference includes obtaining communication data associated with the participant participating in the videoconference. The communication data includes audio signals associated with the participant and/or visual signals associated with the participant. The method includes processing the communication data by a gate control model to generate an output. The output is indicative of an intent of the participant to communicate with other participants of the videoconference. The method includes generating a noise gate status based at least in part on the output associated with the gate control model. The method includes automatically controlling the mute control of the participant based at least in part on the noise gate status.

Abstract: A method enhances brightness in video frames of a video during streams. The method includes determining, by a processor, that a first video frame has low light. The method further includes applying, by the processor, a linear correction to provide a first brightness enhancement in the first video frame that modifies a first brightness of a predetermined darkest percentage of pixels to be less than a darkness threshold value or a second brightness of a predetermined lightest percentage of the pixels to be greater than a lightness threshold value. The method further includes averaging, by the processor, the first brightness enhancement of the first video frame with a set of brightness enhancements corresponding to previous video frames to generate a modified video.

Abstract: A method and a device are provided for determining a global irradiance of solar radiation, and/or at least one of the components thereof, in a plane, wherein the components include direct radiation, diffuse radiation, and radiation reflected on the ground, with a device including at least one radiation sensor unit, a camera, and an evaluation unit which is provided for evaluating measurement data from the radiation sensor unit and/or from the camera. The radiation sensor unit for determining the irradiance of solar radiation is provided in a field of view of 180° over a plane. The camera for detecting a field of view of 180° is provided over a plane. A global irradiance of the solar radiation is measured and converted into the global irradiance and/or into one or more of the components thereof in the horizontal plane and/or in the plane inclined with respect to the horizontal plane.

Abstract: Control logic determines when a network condition has changed by evaluating network condition data. Based on a detected network condition change, the control logic reorders an encoder parameter controller execution sequence of a plurality of encoder parameter controllers. The control logic configures the plurality of reordered encoder parameter controllers so that an encoder parameter determination from a prior encoder parameter controller is used as a decision input for a subsequent encoder parameter controller. An encoder encodes data, such as audio data, video data or other type of data using the generated encoder control parameters from the reordered plurality of encoder parameter controllers. A related method is also disclosed.
