MHEG is the Multimedia and Hypermedia Experts Group. MHEG-5 is an open standard for TV middleware – or application program interface (API) – that enables broadcasters to offer interactive / hybrid services with a wide audience appeal, as well as video. Its TV variant, the MHEG Interaction Channel (MHEG-IC), is used by the UK’s Freeview and Freesat and is also specified by Freeview NZ and Freeview Australia.
