ETSI—the European Telecommunications Standards Institute—has published the latest version of the MHEG interactive TV middleware as a formal European standard.
Version 2.1.1 of ETSI standard 202 184—to give it its official title—contains a raft of very significant updates to the original ETSI MHEG specification from 2004, representing the most important increase in the technology's capabilities since its inception. These include support for the IP-based MHEG Interaction Channel, which enables hybrid broadcast broadband receiver operation via an IP connection—already being used by Freesat in the UK for catch-up TV services—and full support for HD graphics with increased colour depth and screen resolutions.
The ETSI Work Group, which was set up in October 2008, used the MHEG sections of the DTG's D-Book 6 (the detailed interoperability specification for UK digital terrestrial television) as the basis for its work.
