Framework for Multimedia System


               The framework presented here provides an overall picture of the development of
               distributed  multimedia  systems  from  which  a  system  architecture  can  be
               developed.  The  framework  highlights  the  dominant  feature  of  multimedia
               systems:  the  integration  of  multimedia  computing  and  communications,
               including traditional telecommunications and telephony functions.

               Low-cost  multimedia  technology  is  evolving  to  provide  richer  information
               processing  and  communications  systems.  These  systems,  though  tightly
               interrelated, have distinct physical facilities, logical models, and functionality.
               Multimedia  information  systems  extend  the  processing,  storage,  and  retrieval
               capabilities of existing information systems by introducing new media data types,
               including image, audio, and video. These new data types offer perceptually richer
               and more accessible representations for many kinds of information. Multimedia
               communication  systems  extend  existing  Point-to-Point  connectivity  by
               permitting  synchronized  multipoint  group  communications.  Additionally,  the
               communication media include time-dependent visual forms as well as computer
               application conferencing.
