Following the termination of the InView data service on Freeview Mux D, a small number of older models of digital TV recorders will no longer function with a 14 day Electronic Programme Guide (EPG). Models that are compliant with the UK specification for Digital Terrestrial Television (the DTG D-Book) will revert to the broadcast service information which will provide a standard 7 day EPG.
Carriage of the 7 day standard EPG forms part of the requirement for the Digital Tick certification mark. Certified products which carry the Digital Tick signify to consumers that these products will work with the standard 7 day EPG.
