Abstract
In a real-time video transmission system for a cellular-connected unmanned aerial vehicle (UAV) based on an adaptive bitrate provided by the present disclosure, an on-board computer is loaded and configured on the UAV, such that the UAV can provide multiple video streams with different bitrates for retrieval. A client with a bitrate adaptation unit is set up, allowing the system to adjust the bitrate of the video stream according to network conditions in each time interval. Intranet penetration and port mapping are implemented on the cloud server, enabling the client to obtain, from the cloud server, the real-time video stream captured by the UAV. The present disclosure allows a remote user to watch, through a cellular network, the real-time video stream captured by the UAV.
