The MHEG component enables interactive services (Press Red Functionality) on digital TV devices for all transmission networks (DVB-T/S/C). The current standard is ETSI MHEG, which all the country profiles are generated. Furthermore, each country/operator defines their own profile to ensure that the devices deployed into the market can support features used by their MHEG applications. Country profiles supported are Freeview-UK, Freeview-Australia, Freeview-New Zealand, TVB-Hong Kong, Saorview-Ireland and South Africa.
