This Recommendation describes the relationship between the home network (HN) and IPTV-related entities. It also identifies rules and requirements for functions needed on the home network to support IPTV services. It further sets criteria to verify compliance of home network devices, e.g., IPTV terminal devices, to the identified rules and requirements.

The architecture and requirements described in this Recommendation are based on current delivery network technology and thus advanced IPTV services and features that are possible with emerging NGN (next generation network) architecture, e.g., multicast control, are not covered. Advanced IPTV features and services in NGN-based home networks are for further study.
