  • Publication number: 20210105367
    Abstract: The present invention relates to a data transmission control method, an information sending end and receiving end, and an aerial vehicle image transmission system. The data transmission control method includes: receiving data frames sent by a sending end, the data frames being sequentially sent by the sending end in an order of a data frame sequence; and returning an acknowledgement signal corresponding to a currently-received data frame N to the sending end, to enable the information sending end to determine a current network status according to the acknowledgement signal, and adjusting data encoding quality of the sent data frame based on the current network status. In the method, delays for image quality and transmission speed to recover when a network status recovers can be effectively reduced by rapidly determining a current network status based on the feedback of an acknowledgement signal.
