JBIG, short for Joint Bi-Level Image Group, is document compression technology developed by a national standards body.
These applications require support for video coders, speech coders, telephony middleware, JBIG standards (Joint Bi-Level Image Experts Group), MP3, software modem- and other DSP-intensive tasks in addition to supporting a real-time operating system, and system and network management tasks which are better served by a RISC processor.
The OptiSys embedded controller design is targeted at color products up to 25 color pages per minute with standard bi-level image processing capability, as well as variable color processing at reduced speeds.
The industry should be well served by this new bi-level image compression tool, which provides better compression for new applications and systems in the desktop and embedded markets such as facsimile, printing, scanning, document management and Internet imaging.
