This WG aims to examine an IPv6 platform for IPTV and Digital TV as well as the interoperability of various protocols (ECHONET, DLNA, ZigBee, and vendor original protocols) within the home network. The WG intends to establish reference specifications for data measurement, transmission, accumulation and analysis methods for mutual control and management of a multi-vendor network and energy saving environment. The WG is also cooperating with the "Green University of Tokyo Project" and considering collaborations with home networks and city facility management networks.
