ABSTRACT:
A satellite communications system for transmitting medical related images from one or more remote satellite locations to a central headquarters and then sending back diagnostic analysis from the central headquaters to the one or more remote satellite locations by having a high resolution camera and a video compressor for converting high resolution images into voltage analog signals, a modulator for converting the voltage analog signals into a narrow bandwidth and low frequency signal, a satellite system for transmitting and receiving images and analysis, a demodulator for converting the narrow bandwidth and low frequency signal back into a voltage analog signal, a video expander for converting the voltage analog signal into a digital signal, a buffer for buffering the digital signal, a high resolution monitor for converting the buffered digital signal into a high resolution digitized image.
