In this paper, the ATM Mini-Bar System (AMBS) which is a future information providing service infrastructure is proposed. The purpose of AMBS is to provide a multi-media environment in which a user can
(1) select and get quickly any needed information, in low cost, at any time, among very large amount of different media information provided by a variety of providers,
(2) be charged only for the information which is selected and used,
(3) edit or process informations into users' individually requested style or format before using them.
The basic concept and configurations of AMBS are also addressed. This system is basically a center-end oriented one-way information providing system. The information center broadcasts its contents to all user equipments based on a user request forecast, and every user equipment stores the delivered contents in its large storage. A user can select one's needed informations from the storage, and may edit or process them within the user equipment. The charge is only on the read informations from the storage, not on all contents in it. The key points of this system are the following three.
(A) Introduction of a broadcast (or multicast) media for economical information delivery (exactly speaking, it is a predelivery which means a delivery before request) to user equipments.
(B) Introduction of a 1 to 1 communication network for selective charging and control of each user equipments.
(C) Introduction of the user equipment storage for
Quick response to user information request in most cases with the broadcast (or multicast) information delivery media described above,
Separation of information delivery speed and replay speed to increase system flexibility,
Local user information processing or editing.
As an example of technical solutions, a memory architecture, which is based on hierarchical architecture, is described.
AMBS is expected to give some impacts to information industries because it can integrate many kinds of services into the same platform, but some standerdization items are needed to realize it.
