The OTB (Over The Air Bitmap) file extension, developed by Nokia, is used for transmitting black and white bitmap images between mobile phones, particularly Nokia and Siemens models. These images, with a maximum resolution of 255x255 pixels, are often sent via SMS in either hexadecimal text or binary format. Historically, OTB files were popular in the early days of mobile communication for sending simple graphics, icons, and wallpapers when data transmission speeds were limited.
The Braille Ready Format (BRF) is a digital text file format used to store braille transcriptions. Developed by the National Federation of the Blind and the American Printing House for the Blind, BRF files represent braille pages in ASCII text, making them readable by braille displays and embossers. This format supports both contracted and uncontracted braille, facilitating accessibility for visually impaired users. BRF files are essential for converting printed text into a format usable by braille notetakers and refreshable braille displays.
