4 Applicability
The following clauses explain the concept and approach used to define the protocols for the dedicated IPTV subsystem.
4.1 Concept and Approach
This clause outlines concept and approach adopted in the present document. The approach is then applied to protocol
selections, mapping to interfaces and protocol extensions.
The document focuses on defining protocols for flexible functional architecture described in [4], which can:
• Allow development of new IPTV subsystem in NGN;
• Integrate existing IPTV subsystem in NGN;
• Extend both to support other NGN services.
In order to achieve high level of flexibility and support integration of existing subsystems, the work is focused on
evaluating and endorsing protocols already defined for similar functions in [5] and other standard bodies. Protocol
extensions are defined where applicable as well as overall applicability to the end-to-end architecture [4].
For example, recommendations are made how to integrate DVB compliant UE without modifications and DVB
compliant system with minimal modification to the service layer.
4.2 Overview
The clause describes applicability of the protocols discussed further in the present document to reference points defined
in TS 182 028 [4]. The overall functional architecture for the dedicated IPTV service conforms to [4].
Figure 1 presents mapping of protocols to interfaces in dedicated NGN-IPTV and to interworking with other NGN
subsystems and common components.
