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 BIE file extension, associated with the Joint Bi-level Image Experts Group, stands for "Binary Image Entity". This format was developed for efficient compression of binary images, primarily used in fax transmissions. Introduced in 1993, JBIG1 provided lossless compression, outperforming earlier standards like CCITT Group 3 and 4. It was later succeeded by JBIG2, which offered improved compression efficiency for bi-level images.
