  • Assignee:
    Blue Jeans Network, Inc. - Mountain View CA
  • International Classification:
    H04N 7/14
  • US Classification:
    348 1408, 348 1401, 348 1402, 348 1403, 348 1407, 348 1409
  • Abstract:
    A new approach is proposed that contemplates systems and methods to support the operation of a Virtual Media Room or Virtual Meeting Room (VMR), wherein each VMR can accept from a plurality of participants at different geographic locations a variety of video conferencing feeds of audio and video streams from video conference endpoints. A globally distributed infrastructure that supports operations of the VMR through a plurality of MCUs (Multipoint Control Unit) built from off-the-shelf components instead of custom hardware as media processing nodes, each configured to process the plurality of audio and video streams from the plurality of video conference endpoints in real time. Each single VMR can be implemented and supported across the infrastructure of globally distributed set of servers/media processing nodes co-located in Points of Presence (POPs) for Internet access, wherein such massively distributed architecture can support thousands of simultaneously active VMRs and yet is transparent to the users of the VMRs.

  • International Classification:
    H04N 7/15
  • US Classification:
    348 1409, 348E07084
  • Abstract:
    A new approach is proposed that contemplates systems and methods to support the operation of a Virtual Media Room or Virtual Meeting Room (VMR), wherein each VMR can accept from a plurality of participants at different geographic locations a variety of video conferencing feeds from video conference endpoints that can be either proprietary or standards-based and enable a multi-party video conferencing session among the plurality of participants by composing one composite audio and video stream for each of the participants. Each single VMR can be implemented across an infrastructure of globally distributed set of servers/media processing nodes co-located in Points of Presence (POPs) for Internet access. Each VMR also gives its users a rich set of conferencing and collaboration interaction hitherto not experienced by video conferencing users.

  • US Classification:
    715753
  • Abstract:
    A new approach is proposed that contemplates systems and methods to support the operation of a Virtual Media Room or Virtual Meeting Room (VMR), wherein each VMR can accept from a plurality of participants at different geographic locations a variety of video conferencing feeds of audio and video streams from video conference endpoints. The approach provides collaborative viewing of an event through the VMR so that the participants at geographically distributed locations are able to simultaneously participate and share the experience of the event together. An initiating participant of the event sharing is further offered with in-meeting management and control over the content to be shared at the event. A globally distributed infrastructure supports the sharing of the event among the participants at geographically distributed locations through a plurality of MCUs (Multipoint Control Unit), each configured to process the plurality of audio and video streams from the plurality of video conference endpoints in real time.

  • US Patent:
    20230057544, Feb 23, 2023
  • Filed:
    Jul 8, 2022
  • Appl. No.:
    17/811496
  • Inventors:
    - Basking Ridge NJ, US
    Satish Malalaganv Ramakrishna - Yellapur, IN
    Michael Grupenhoff - Palo Alto CA, US
  • International Classification:
    H04L 65/80
    H04L 65/403
  • Abstract:
    A device may include a processor configured to monitor a user of a video conferencing application. The processor may be further configured to determine that the user corresponds to a passive user based on the monitoring; switch a setting for the video conferencing application for the user from real-time video to video streaming, in response to determining that the user corresponds to a passive user; generate a delay between receiving content via the video conferencing application and playing the content by the video conferencing application, wherein the delay progressively increases from no delay to a particular delay value over a time period, in response to switching the setting for the video conferencing application for the user from real-time video to video streaming; and play the received content using the video conferencing application based on the generated delay.

  • International Classification:
    H04N 7/14
    H04L 29/06
    H04N 7/15
  • Abstract:
    A data stream from an internal endpoint of a video conference participant is received at an enterprise media processing node. The internal endpoint is accessible to the enterprise media processing node behind a firewall on an enterprise network. The received data stream is translated and transcoded into a predefined common communication protocol. A data stream in the common communication protocol is received at an external media processing node using a firewall friendly protocol to traverse the firewall from an external endpoint. The external endpoint communicates with the external media processing node outside the enterprise network. A composite data stream of the received data streams from endpoints within the enterprise network and outside the enterprise network is selectively generated, and sent to the internal endpoint.
