  • Method and apparatus for transmitting video streams in WiFi mesh networks
    Patent number: 11343585
    Abstract: The present disclosure provides a technical scheme for transmitting video streams in WiFi mesh networks, including a method for transmitting multicast video in an access points in a WiFi mesh network, wherein the method includes: receiving a video stream and determining the node(s) to which the video stream needs to be transmitted, wherein the video stream includes a multicast address; determining dynamically a transmission mode of the video stream and transmitting corresponding video stream to multiple stations using the transmission mode when the nodes are the multiple stations corresponding to the multicast address; transmitting corresponding video stream to a next access point using unicast mode when the node is the next access point.
