The purpose of DSL, the infrastructure of cable television or own broadband networks such as fiberglass. Second, the Residential Gateway provides an interface for all existing within the residential area networks and bus. These are used to connect devices and their connection to the Residential Gateway.

In the context of OSGi ( Open Services Gateway Initiative ) and other approaches is meant by a Service Gateway - and thus a Residential Gateway - a kind of advanced router functionality, but as a gateway (service aggregator on a small scale ) for the entire house. Embedded Java and OSGi are not least here favors very strong because a very general service orientation also requires very strong platform independence. Here there are strong requirement overlaps with the MHP approach for the realization of service offerings in the digital television.
