This is an image format that can be transmitted over analog broadcasting channels. It has a 16-bit structure, and it is transmitted using a three-component YUV color model. One component is responsible for brightness, and the remaining two account for differences in color.

This format was created by Nokia for use in its proprietary phones. A bitmap image was used to transfer image files between devices over a wireless connection. It was mainly used when exchanging multimedia text messages that support inserting pictures.
