Multimedia communication

The purpose of this Encyclopedia of Multimedia Technology and Networking is to offer a written compendium of human knowledge related to the emerging multimedia digital metamarket. Multimedia technology, networks and online interactive multimedia services are taking advantage of a series of radical innovations in converging fields, such as the digitization of signals, satellite and fibre optic based transmission systems, algorithms for signal compression and control, switching and storage devices, and others, whose combination has a supra-additive synergistic effect.
