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