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.
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.
2 References
References are either specific (identified by date of publication and/or edition number or version number) or
non-specific.
• For a specific reference, subsequent revisions do not apply.
• Non-specific reference may be made only to a complete document or a part thereof and only in the following
cases:
- if it is accepted that it will be possible to use all future changes of the referenced document for the
purposes of the referring document;
- for informative references.
Referenced documents which are not found to be publicly available in the expected location might be found at
