  • Patent number: 11336561
    Abstract: An IP router capable of isochronous switching of a packetized media stream. According to an example, the IP router parses the RTP header within an incoming IP datagram to extract the RTP time stamp, which provides a time value for a unique IP Flow. By inspecting the header, the IP router can switch the flow at the point in time that the RTP time stamp value changes, or matches a target value. In one aspect, the IP router looks for the change in the RTP time stamp value and performs the switch based on the detected change. In another aspect, the IP router performs the switch at a specified time stamp value that can be unique to a group of signals or based on a common “sync” value published to all the ports of the IP router.

  • Patent number: 11323660
    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.
