| Abstract: | The scheme of the digital video image transmission system for Unmanned Aerial Vehicle(UAV) TT&C system is proposed.The position localized requirement for the coded data block in the RS+convolution encoding system is analysed, and using the frame synchronization loop to locate the coded data block is presented. According to the special requirement of the frame synchronization loop for the data stream,the data rate matching problem caused by the FPGA digital system characteristics is discussed and solution is provided. |
