Models for storing and presenting multimedia documents

This paper deals with models for storing and presenting multimedia documents integrating large amounts of data of different types. Usually, multimedia systems integrate a variety of data such as voice, graphics, text video and other types of images into a single document. Most of these data are not structured and therefore require a huge storage capacity. Such a requirement causes many problems for traditional database management systems which were not originally designed to manipulate data other than text. The presentation of multimedia documents incorporates documentary research that depends upon storage model and mechanisms. In this paper, we present two data storage models and several other associated models for the presentation of multimedia documents. The analysis of these models reveals their capacity to synchronize various temporal scenarios while allowing users simultaneous and secure access to multimedia systems.
