`Scope
`
`1
`The present document provides the stage 3 description of the dedicated IPTV subsystem based on the architecture and
`stage 2 information flows described in TS 182 028 [ 4].
`
`The protocol enhancements will form the scope of new or enhanced protocol specifications.
`
`The interaction with other NGN subsystems such as PES, IMS and RACS will be considered.
`
`the interface between the User Equipment (UE) and the SD&S;

`
`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 inte1working with other NGN
`subsystems and common components.
