The HbbTV (Hybrid Broadcast Broadband TV) consortium today announced that since opening for membership in May 2011 it has now reached fifty members. HbbTV is an industry initiative that brings together broadcast and broadband TV services into one seamless user experience. The HbbTV standard utilises existing standards and web technologies including OIPF (Open IPTV Forum), CEA, DVB and W3C. Version 1.1.1 of the specification was published by European standards agency ETSI in June 2010. At IBC over thirty companies will demonstrate HbbTV implementations.
