To enhance the capacity of video capturing and ground reconnaissance of an unmanned aerial vehicle(UAV),an efficient MPEG-4 high definition video encoder is designed and implemented on a digital signal processor(DSP) platform,which is characterized by small volume,low power consumption and high reliability.Firstly,the data flow scheme of video encoding is optimized by allocating the on-chip memory of the DSP reasonably,which reduces the impact of data access on encoding speed.Secondly,prediction-based motio...
