Abstract: A conference endpoint receives a selection of an option to initiate a sharing session in which a video of a user is overlaid on a presentation of shared content during a video communication session, the user being one of multiple users participating in the video communication session via the conference endpoint. The conference endpoint identifies one of the multiple users as a presenter for the shared content; and transmits, to a meeting server, information associated with the sharing session, which includes one of a video of the presenter overlaid on the shared content, or the shared content, a video of the multiple users, and information identifying the presenter in the video of the multiple users to a meeting server for overlaying, by the meeting server or a receiver conference endpoint, video of the presenter on the shared content during the video communication session.

Abstract: Distance-based framing includes obtaining at least a video stream during an online conference session. The video stream, an audio stream received with the video stream, or both the video stream and the audio stream are analyzed and a framing that either focuses on a speaker in the video stream or provides an overview of participants in the video stream, the framing being is composed based on the analyzing. A potential error in the framing is detected based on further analysis of at least one of the video stream, the audio stream, or distance sensor data received with the video stream. If the distance sensor data contradicts the potential error, the framing is maintained, but if the distance sensor data confirms the potential error, a new framing is generated.

Abstract: A method, computer system, and computer program product are provided for virtual background replacement during a video communication session. A frame comprising a user image and a captured background is obtained from a video capture device as part of a video stream. The frame is processed to replace the captured background with a virtual background. A change to an exposure characteristic of the video capture device is determined. In response to determining the change to the exposure characteristic, the virtual background is modified to match a virtual background brightness with a user image brightness to produce a modified virtual background. The frame is modified by combining the user image with the modified virtual background.

Abstract: A video conference system may include two or more video conference endpoints, each having a display configured to display content. The video conference system may detect a plurality of participants within a field of view of a camera of the system. The video conference system may determine an attention score for each endpoint based on the participants. The video conference system may determine whether the content of the first endpoint and/or the content of the second endpoint are active content based on whether the attention scores exceed a predetermined threshold value. The video conference system may send to secondary video conference systems an indication of the active content to enable the secondary video conference systems to display the active content.

Abstract: A camera system for a video conference endpoint includes a fixed wide lens camera providing a view of a space, a first fixed camera providing a view of a first portion of the space, a second fixed camera providing a view of a second portion of the space, a third fixed camera providing a view of a third portion of the space, and a processor operatively coupled to each of the cameras. Each of the cameras is configured to produce a video signal and the processor is configured to receive the video signals and select a relevant video signal from the video signals. The processor is also configured to process the relevant video signal by digitally panning, tilting, and zooming of the relevant video signal to generate a video stream from the processed video signal.

Abstract: A video conference endpoint includes one or more cameras to capture video of different views and a microphone array to sense audio. One or more preset views are defined. The endpoint detects faces in the captured video and active audio sources from the sensed audio. The endpoint detects any active talker detected faces that coincide positionally with detected active audio sources, and also detects whether any active talker is in one of the preset views. Based on whether an active talker is detected in any of the preset views, the endpoint switches between capturing video of one of the preset views, and capturing video of a dynamic view.
Abstract translation: 视频会议端点包括用于捕获不同视图的视频的一个或多个摄像机和用于感测音频的麦克风阵列。 定义一个或多个预设视图。 端点从感测到的音频中检测拍摄视频中的人脸和活动音频源。 端点检测与检测到的活动音频源在位置上重合的任何有效的说话者检测到的面部，并且还检测是否有任何活跃的讲话者处于预设视图之一。 基于在任何预设视图中是否检测到主动讲话者，端点在捕获一个预设视图的视频和捕获动态视图的视频之间切换。

Abstract: Presented herein are techniques for cropping video streams to create an optimized layout in which participants of a meeting are a similar size. A user device receives a plurality of video streams, each video stream including at least one face of a participant participating in a video communication session. Faces in one or more of the plurality of video streams are cropped so that faces in the plurality of video streams are approximately equal in size, to produce a plurality of processed video streams. The plurality of processed video streams are sorted according to video stream widths to produce sorted video streams and the plurality of sorted video streams are distributed for display across a smallest number of rows possible on a display of the user device.
