The OTB (Nokia Over The Air Bitmap Image) file format is a type of image file developed for use on Nokia mobile devices. These files are specifically optimized for efficient transmission and display on Nokia phones, particularly older models. The OTB format is designed to be compact to facilitate over-the-air (OTA) transmission, which was an essential feature in the era of limited bandwidth and data transfer capabilities. The format supports monochrome graphics, making it suitable for simple images like icons and logos.
Unicode Braille (uBrl) is a file format that stores information in the form of a braille code, which is a tactile writing system used by people who are blind or have low vision. The file format is used to store text in a way that can be read by a braille device or software.
