Abstract

A system (27) and methodology for automatically organizing, managing, and distributing digital multi-media information without the negative artifacts which are normally introduced when electronically distributing digitally compressed data and information which contains still images, moving images and sound. Object descriptor fields define the actual multi-media object and its relative mixture of digitized audio, video, text and picture content. Multi-media information packets and segments descriptors are transmitted over available transmission system architectures.
