The protocol between the terminal and the End-Service Provider has to exist within the limitations of the access network. The current situation offers the benefits of
26、 consistency and well-defined interfaces for the access networks. Two types of access services dominate: the public telecommunications network that provides Plain Old Telephone Service (POTS) and the private broadcast entertainment network that provides “cab1 ision service.

Service Providers will provide portable services that will be available wherever the user requires communications, and will facilitate

Throughout the consumers conversation, the call is seamlessly transferred among various public and private communications networks as necessary, and the consumer is not aware of the network switching. In this vision, customer premises equipment may provide particular features and provide ser

While eventually all data exchanged between terminals or terminal-services may become disital data and transmitted in baseband, the Multimedia Premises Reference Architecture acknowledges that existing terminals often use analog

This hypothesis will be valid for both narrowband and broadband networks. II Copyright Telecommunications Industry Association Provided by IHS

INTRODUCTION This document fills a recognized need in the telecornmunications industry. entertainment industry, and computing industry brought about by the National information Infrasmcture/Globa1 information
44、 infrastructure (NII/GII) requirements and demands for new end-user services that address the delivery of existing, envisioned, and Funire services to the home and business environments. It will be useful to anyone engaged in the manufacture and sale of telecommunications terminals equipment and to
45、those purchasing, operating, or utilizing such equipment. The requirements in this issue are formulated and defined to some extent from Digital Audio-Visual Council (DAVIC) specifications as well as other technical standards in order to ensure compatibility with existing networks while recognizing t
46、he technical advances in future telecommunications standards. 1.1 Purpose The Multimedia Premises Reference Architecture Standard establishes an a l framework for end-to-end architecture consists of functional blocks which are not necessari requirements should assure users of a good quality of servi

As residents add more functionality they will redesign their systems. Over time it will appear that the configuration of the equipment is migrating or evolving from what

To plan for this equipment lets consider homes at three periods: today, a transition period, and the long-term future (see Figure 2). Although each home may have its unique characteristics, and each customer may have his or her own unique needs, it is still possible to describe the major tre
