Chroma encoders create s-video or composite video from RGB.

Chroma decoders disassemble composite or s-video and rebuilt an RGB signal. All TVs perform this function, and many arcade machines - particularly DVD or LD machines, to drive the RGB monitor from other signals.

Upscanners usually create VGA signals from TV-rate signals (31kHz+ from 15kHz). You can also downscan, such as creating TV from VGA, but since most modern video cards offer this option it's becoming less common.

Also called VGA boxes, among other things.
