From the developer:
SSTV -Sites monitors web-sites which have SSTV images uploaded to. It has a picture transmission method used mainly by amateur radio operators, to transmit and receive static pictures via radio in monochrome or color. Broadcast television requires 6 MHz wide channels, because it transmits 25 or 30 picture frames per second.
