Abstract: A method includes: determining, by a videoconference server, a level of tolerated risk for a videoconference between a presenter and an attendee; obtaining, by the videoconference server, sensor data from at least one sensor at a location where a user device of the attendee displays the videoconference; generating, by the videoconference server, a current risk score based on the sensor data; determining, by the videoconference server, the current risk score exceeds the level of tolerated risk; and presenting, by the videoconference server and in response to the determining the current risk score exceeds the level of tolerated risk, an alert to the presenter of the videoconference.

Abstract: A system and method for managing a conference call using a selective transmission unit (STU) to manage multiple client devices participating in the conference call. In one example, the STU uses video transmission parameters and video reception parameters from each of the client devices to control which video streams are sent by the client devices to the STU. The STU then sends particular received video streams to each of the client devices based on the video reception parameters of the respective client device.

Abstract: This disclosure is directed to facilitating voice and video communication between users independent of a location or a device. A communication request can specify users, who may be identified and located in their respective environments. For example, users can be identified and located using facial recognition imaging techniques and/or by monitoring a radio frequency (RF) signal associated with a device that is carried or worn by a user. After determining a location of a user, individual devices can be configured as a functionally grouped device to allow the users to communicate. For example, capabilities of a television, microphone, speaker, and imaging device can be combined to allow a video communication between users. Further, as a user moves around his or her environment, the location of the user can be tracked and additional functionally grouped devices can be provided for seamless communication.

Abstract: Embodiments provide a method and system for audio generation from contextual text input is provided. The disclosure gives due importance to the granularity of the content. The system allows the user to specify the properties of the audio to be generated. Here, context is used to identify the importance of a particular sound over the others and thus automatic adjustments of the audio output to give a more realistic feel. The system generates dataset for training audio models. The user can give input query in natural language and the audio requested will be generated for training and developing the necessary classification or other necessary audio models. The system provides a feature of automated fine-tuning of the model parameters to suit the new automatically collected training data. Furthermore, the system provides a pre-trained inbuilt model repository with audio models belonging to the main categories of noises.

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: A document management system integrates with a video conference system to ensure that proper electronic witness procedure is performed for document validation. The document management system accesses a video conference between a user and an electronic witness, and then instructs the user to electronically sign the document while the electronic witness observes. The document management system receives confirmation that the electronic witness observed the video of the user electronically signing the document. The document management system combines and stores portions of the video conference that correspond to the electronic witness's validation of the document.

Abstract: Techniques for selective video conference segmentation are described and are implementable in a video conference setting. The described implementations enable control over segments of video content that are viewable by a given participant in a video conference. For instance, segments of video content are generated that represent spatial portions of video content captured by a host device. The segments can be configured in a variety of ways for inclusion in one or more video streams. The video streams can be communicated to different participants within the video conference, for instance based on a status of a given participant, thus providing different fields of view to different participants.

Abstract: One example system for sharing content across videoconferencing sub-meetings includes a system comprising a processor; and at least one memory device including instructions that are executable by the processor to cause the processor to establish a videoconferencing session including a main meeting and a first sub-meeting, receive a content transmitted over a data stream to be displayed in the main meeting; cause the content to be displayed in the main meeting, receive a request to subscribe to the data stream over which the content is transmitted, and responsive to receiving the request to subscribe to the data stream, cause the content to be displayed in the first sub-meeting simultaneously with the content displayed in the main meeting.

Abstract: One example method for displaying ephemeral content in video conferences includes receiving a video conference stream at a client device, displaying the video conference stream on a display in communication with the client device, displaying a content layer over the video conference stream on the display, receiving a content item from a user input device in communication with the client device, displaying the content item in the content layer at a first time, and when a predetermined period of time has elapsed from the first time, automatically removing the content item from the content layer.

Abstract: An audio-only caller is determined to be accessing a conference using a landline phone. The audio-only caller is prompted to provide name information via a text-based message. A response that includes the name information is received. The name information is displayed via a user interface of the conference.

Abstract: A best available video stream is determined for each of multiple conference participants within a conference room including multiple cameras based on scores determined for video streams obtained from the cameras. The scores are determined based on representations of the conference participants within the video streams, for example, based on percentages of conference participant faces visible within the video streams, directions of conference participant faces relative to the cameras, directions of eye gaze of the conference participants relative to the cameras, and/or degrees to which conference participant faces are obscured within the video streams. The best available video streams are output for rendering within separate user interface tiles of conferencing software.

Abstract: An electronic device, computer program product, and method are provided that automatically focus on meaningful content in an image stream during an instruction-oriented video communication session. The electronic device communicatively connects the electronic device via a network to image stream transmitting (IST) electronic device(s) during a video communication session. A controller of the electronic device identifies a person and a writing surface within an image stream received from the IST electronic device. In response to determining that the person is attending to the writing surface, the controller presents on display device(s) a first portion of the image stream that focuses on the writing surface. In response to determining that the person is not attending to the writing surface, the controller presents on the display device(s) a second portion of the image stream that does not focus on the writing surface.
