Real time L-band Moving Picture Transmission and MPEG Encoding for Micro-Aerial Vehicle Application

Transmission and MPEG encoding characteristics of real time moving picture images using L-band transmitter and receiver which can be used for micro-aerial vehicle(MAV) application are reported. NTSC picture images are transmitted from a moving vehicle with transmitter power of 50 mWatts at 970 MHz carrier frequency for frequency modulation(FM). Received signal is demodulated and compressed with an MPEG encoder installed in a notebook PC in real time. MPEG images show favorable data reduction ration greater than 100 from uncompressed data and also show better image quality and continuity than those of avi images. Experiments show very encouraging image quality applicable to MAV surveillance and observation.
