What is SSTV?

Slow-scan television, a way to send pictures as sound. Copthorne Macdonald proposed it in 1957. Radio amateurs have used it for decades, and the International Space Station sends pictures to Earth this way from time to time. A picture is scanned line by line, and each point becomes a pitch. The receiver turns the pitches back into colors and rebuilds the picture.
