Interoperability in in-home digital networks

We investigate those aspects of in-home digital networks (IHDN) that have influence on the interoperability between the devices connected to these networks. This led to a structured taxonomy of such aspects. The structuring is basically made by distinguishing between streaming and device control. Device control is further split-up in four different levels, offering increasing degrees of interoperability. The resulting taxonomy can be used for depicting a specific IHDN standard or technology and thus allows a structural comparison between IHDNs. Such a comparison itself is not part of this document.
