Transmission of Compressed-Video Signals Via FM Subsidiary Communications Authorization

A method of transmitting stationary TV pictures within the bandwidth of an FM subsidiary communications authorization (SCA) subchannel and utilizing conventional cameras and monitors is discussed. Time-domain and frequency-domain representations of the compressed-video baseband signal are examined. Processing of the baseband signal for SCA transmission is then considered. Experimental results of actual SCA transmission including an STL are presented. Areas for further investigation are suggested.
