9、oadmap is intended as a companion to ATIS-0800002, IPTV Architecture Requirements. As the IPTV Requirements document is revised, further revisions to this Roadmap document may be required. This document is intended to help guide the architecture specification development work of the IIF. The Roadmap

10、 provides an industry consensus perspective on the prioritization and scoping of the specification development efforts of the IIF. The objective is to use this document to help develop the rationale to support the initial set of more detailed issue statements that will drive the development of the a

The general assumption is that the internal interfaces (b) of a logical domain would have

14、a notch lower priority than the externally visible service functions. 6 ATIS-0800003 Table 2 - Priorities of Logical Domains and Interfaces Logical Domain / Interface Reference # Name Priority 1 Consumer (a) 1 1 Consumer (b) 2 2 Network Provider (a) 2 2 Network Provider (b) 3 3 Service Provider (a)

16、 - An implication of the scoping guidelines in section 2.2 is that it may not be possible to completely specify all of the aspects of a particular interface in a single document. Hence the specifics of the proposed deliverables and their associated issue statements become relevant. These are discuss

17、ed further in section 5. It is important to identify the infrastructural components of the IPTV architecture at its earliest stage. The main goal is to achieve a reusable design of the identified basic components and auxiliary services, such that they could be used by different services composing th

18、e wider IPTV system. It is also beneficial that the Roadmap document contains the sections dedicated to these basic components and auxiliary services with phases and estimation of the amount of work for each. The Interfaces are numbered according to Figure 1 - IPTV Logical Domains and Interfaces (Nu

46、sues statements to provide a coherent perspective on the standardization work to be completed in developing the specifications for the IPTV Service. These prototype deliverable definitions and issue statements are grouped by the logical domains and interfaces to which they apply. The logical domains

47、 and interfaces are roughly in the priority order developed in section 4. All these deliverable definitions should be focused on the services categorized into Phase 1. The specifications that these deliverable definitions provide the basis for are not expected to be exhaustive; rather, they should b

The architecture

49、should consider material presented in Figures 1 - 4 , 22, and 23 of ATIS-0800002, IPTV Architecture Requirements, and Figure 6 of IIF-WT-004, Framework for QoS Metrics and Measurements supporting IPTV Services. The goal is to provide a framework for end-to-end systems, network design, and their implementation. This will serve as a reference architecture for the IPTV functional subsystems to be defined in sepa
