Multi-media information services: a laboratory study

An overview is given of the work of a research group studying advanced information services. The general form of today's information services is discussed as a baseline for considering the future, and some key technological advances (including a broadband public-switched network) that are expected to greatly influence the continuing evolution of such services are listed. A description is given of a multimedia information services laboratory, consisting of a services testbed and application prototypes, which was constructed to illustrate and study important aspects of future services. The end-to-end performance requirements for these services are examined. Two examples are given to illustrate universal communications.<
