  • Patent number: 10285112
    Abstract: Techniques are generally described related to a mobile ad-hoc network. One example method for transmitting data from a source node to a destination node in a mobile ad-hoc network may include receiving a route reply packet from a first node by a second node; identifying the route reply packet as an overheard route reply packet by the second node; adding a first routing entry in a routing table of the second node and the first routing entry being associated with the overheard route reply packet by the second node; broadcasting a routing entry added message associated with the first routing entry by the second node; receiving data transmitted from a third node and the data being transmitted by the third node responsive to the routing entry added message by the second node; and sending data received from the third node towards the destination node via an active route established based on the first routing entry in the routing table of the second node by the second node.

  • Patent number: 9722936
    Abstract: A method and apparatus for rate adaption of HTTP stream media is disclosed in this invention. The method comprises: acquiring from a server a stream media with a selected video rate at a client adopting the TCP protocol at its transmission layer and the HTTP protocol at its application layer, wherein the selected video rate allows an amount of buffered data to be maintained in a predetermined range in a buffer for buffering the stream media under a current download rate speed. This invention may improve user experience.

  • Patent number: 9106404
    Abstract: Disclosed is a method for transmitting a video, which is used for increasing video transmission and receiving quality. The method comprises: generating multiple layers of video streams; in accordance with an obtained first distortion value, obtaining a corresponding first antennae/video matching matrix; separately dispatching each layer of video streams to respective antennae in accordance with the first antennae/video matching matrix; and transmitting same in accordance with the dispatched video streams. Also disclosed are a device for achieving the method, and a method and device for receiving a video.
