Abstract
A system 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. The invented system packages and assists in production and electronic distribution of pre-produced multi-media information into digital packets or segments of varying file lengths with defined start and end points. Each segment of multi-media information is identified with separate alpha-numeric and binary coded data fields which are organized into multimedia "object descriptors" and multi-media "segment descriptors". Object descriptor fields define the actual multi-media object and its relative mixture of digitized audio, video, text, and picture content its life span for use, date and time release information for use, killdate, and file sizes. The "segment descriptor" information packet identifies the starting point of the segment, the ending point of the segment, the segment title and related information namely, the type and configuration of each multi-media information segment.
