1 Scope
The present document specifies the architecture and functions of an IPTV system that makes use of the NGN IMS
architecture and its features, implementing the requirements defined in TS 181 014 [14] and TS 181 016 [15].
The present document has taken IPTV solutions defined by other organizations (such as DVB, ATIS IIF, etc.) into
account. It is based on an IMS based architecture and where appropriate the aforementioned solutions are referenced.
By relying on common components the resulting architecture can coexist with other TISPAN NGN services.
