Abstract: An image processing method includes a transmitting terminal receiving a feedback message sent by a receiving terminal. The feedback message indicates a reception state of a received image frame sent by the transmitting terminal and received by the receiving terminal before the receiving terminal sends the feedback message. The method further includes acquiring a target image frame, encoding the target image frame according to a preset error correction mechanism to generate encoding data of the target image frame in response to the feedback message indicating a reception error, and sending the encoding data of the target image frame to the receiving terminal.

Abstract: A location of an unmanned aerial vehicle (UAV) is collected while the UAV is flying along a flight path. A communication signal distribution in a proximity of the location is determined. One or more relay locations for arranging one or more relays are determined based on the communication signal distribution to improve communication coverage along the flight path. An identification of the UAV is transmitted to an authentication center for authentication, without using the one or more relays, in response to determining, based on the communication signal distribution, that the UAV is capable of directly communicating with the authentication center or a communication network associated with the authentication center above a quality threshold.

Abstract: A computer-implemented method includes receiving a feedback message from a receiver of image data. The feedback message includes a reference frame identifier associated with a reference frame correctly received or decoded by the receiver. The method further includes determining a difference between the reference frame identifier and a current frame identifier. The current frame identifier is associated with a current frame to be encoded and the difference indicates a number of frames between the reference frame and the current frame. The method also includes encoding the current frame based at least in part on the difference.

Abstract: A method of controlling a transmission power of a first node configured to communicate wirelessly with one or more other nodes is described. The method may include establishing a first wireless communication link between the first node and a second node, receiving a first power adjustment value from the second node, wherein the first power adjustment value is determined based on signals transmitted by the first node over the first wireless communication link, determining a transmission power level for transmitting signals from the first node based on the received first power adjustment value, and transmitting signals from the first node over the first wireless communication link using the determined transmission power level.

Abstract: A method for transmitting images includes obtaining image data of an image frame. The method also includes encoding the image data of the image frame to obtain first encoded image data. The method also includes determining a transmission delay of the first encoded image data. The method further includes re-encoding the image data of the image frame to obtain second encoded image data in response to determining that the transmission delay of the first encoded image data is not within a predetermined range.
