The DjVu file extension, developed by AT&T Labs in 1996, stands for "Digital Journal Viewer". It is designed to store scanned documents and combine text, line drawings, and images with high compression efficiency. DjVu files are widely used for digitizing books, magazines, and historical documents due to their ability to produce smaller file sizes compared to PDF, JPEG, and TIFF formats. This format employs advanced technologies like image layer separation, progressive loading, and arithmetic coding, making it ideal for web distribution and archival purposes.
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.
