免费在线 OTB 转 PAL 转换器

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.

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.
