Title:
DATA TRANSMISSION CONTROL METHOD, INFORMATION SENDING END, RECEIVING END AND AIRCRAFT IMAGE TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/242620
Kind Code:
A1
Abstract:
The present invention relates to a data transmission control method, an information sending end, a receiving end and an aircraft image transmission system. The data transmission control method comprises: receiving data frames sent by a sending end, wherein the data frames are sent by the sending end in succession according to the order of a data frame sequence; and returning, to the sending end, a response signal corresponding to a data frame N which is currently received, so that the information sending end determines a current network state according to the response signal and adjusts, based on the current network conditions, data encoding quality of the sent data frames. The method can quickly confirm the current network state based on feedback of the response signal and effectively reduce a delay in recovery of image quality and of a transmission speed when the network state is recovered.
