  • Patent number: 10305863
    Abstract: Systems and methods of the present disclosure are directed to a telecommunications management system (TMS) that receives an indication from a first user to participate in a telecommunication. The TMS can identify a characteristic of the first user and compare the characteristic with one or more characteristics of each user of a pool of users. The TMS can select, based on the comparison, a second user of the pool of users that matches the first user. The TMS can initiate, responsive to selecting the matching second user, an anonymous telecommunications channel between the first user and the second user.

  • Patent number: 10237581
    Abstract: An online system receives a media stream from a host of a live broadcasting stream and a second media stream from a guest of the host, and generates a single composite stream that includes the multiple live streams. The online system decodes and aligns the video and audio frames of each live stream to ensure that the composite stream displays the multiple live streams in a synchronized fashion. Additionally, the composite stream can display the multiple live streams in a particular format (e.g. side-by-side, or picture-in-picture), and therefore, the online system adjusts the video and audio frames of each live stream to fit that format. For each composite stream, the online system employs a decision engine that identifies the optimal set of encoded composite streams based on a variety of characteristics. The online system encodes the composite stream and distributes the appropriately encoded composite stream to client devices for display to viewers.

  • Patent number: 10134414
    Abstract: A videoconference apparatus at a first location detects audio from a location and determines whether the sound should be included in an audio-video stream sent to a second location, or excluded as an interfering noise. Determining whether to include the audio involves using a face detector to see if there is a face at the source of the sound. If a face is present, the audio data from the location will be transmitted to the second location. If a face is not present, additional motion checks are performed to determine whether the sound corresponds to a person talking, (such as a presenter at a meeting), or whether the sound is instead unwanted noise.

The camera is controlled to dynamically adjust each of the dynamic views to track changing positions of detected faces over time, and dynamically switch the camera between the preset views, the dynamic overview, and the dynamic close-up view over time based on positions of the detected faces and the detected active talkers relative to the preset views and the dynamic views.

  • Patent number: 9843771
    Abstract: A method and apparatus for controlling a live avatar include features for directing the live avatar gaze to be consistent with a remote operator's view of the live avatar's surroundings. Indication of gaze direction may be continuously provided to the live avatar using movable optics, for example a heads-up display, or a movable optical prism or lens. Gaze direction or operator commands may be communicated using a haptic device. Video and control streams from multiple live avatars may be aggregated through a host server and allocated via an online interface to multiple prospective remote operators.

  • Patent number: 9832087
    Abstract: Techniques are described herein for facilitating a connection between a cloud networking platform and a unified communication system, where the cloud networking platform hosts communication services including real-time communications for client devices, and the unified communication system hosts communication services including real-time communications for on-prem devices that are associated with the unified communication system. Events associated with the cloud networking platform are monitored at the unified communication system, via a cloud connector device of the unified communication system, where events are associated with users who are registered with client devices and on-prem devices, and the events include real-time communications. A notification is provided to one or more client devices registered to a first user in response to an on-prem device also registered to the first user receiving a real-time communication request from a device of another user.

  • Patent number: 9826138
    Abstract: Multiple cameras may be controlled over a wide area network in a routine that includes aggregating video processing capabilities of the cameras into a first graphics processing unit resource pool. The first graphics processing unit resource pool is operated on raw video feeds of the cameras to combine and transform the raw video feeds into a virtual video feed, wherein at least one camera of the cameras processes a raw video feed output by a different camera of the cameras. The virtual video feed is communicated over the wide area network to a master video processor, which is operated in a feedback loop to analyze the virtual video feed and control the first graphics processing unit resource pool to improve one of a quality or a content of the virtual video feed.
