Slow Scan TV (SSTV) is a still image transmission method used to transmit and receive images via RF. To send and receive images, you need to connect your amateur radio rig thru an audio interface to your computer. Then use software to send and receive images. Images take about one minute to be received.

The Robot Research Corporation developed this mode for their own SSTV equipment. The most popular variations are called Robot 72 and Robot 36. Robot is compatible with BW, RGB and YUV color schemes. Robot uses scanline amounts of 120, 128, 240 or 256 lines to transmit the picture. Transmission time varies from about 8 to 72 seconds for the entire image.
This mode was designed by Martin Emmerson to improve SSTV transmissions. Martin scans 240 lines out of 256 and reserves the first 16 so that the sender has a room for a banner on the top or bottom of the image. This space is usually used to include a message or signature. Martin takes longer than Robot to load the image about 58 to 114 seconds.
Like Martin, Scottie was created to enhance the ROM capability of Robot. Scotty was created by Eddie Murphy and became a mode all its own. It scans all 256 lines as well the banner space. Scottie is slightly faster than Martin and can recreate the image in about 71 to 110 seconds and uses RGB as the color scheme.
