The InView EPG is currently available on over 5 million Freeview boxes, with the extra 3 million being added over the next few months.
The InView EPG offers viewers a detailed 14-day programme schedule across all Freeview channels. It also features an on-screen guide and direct links to digital Teletext services.
Furthermore, the service allows broadcasters to promote their programmes, individual channels, or channel bouquets through a unique “Guest Channel”.
The service is currently being trialled by ITV, with adopters including Channel 4, Virgin Media and Dave.
The deal coincides with InView's third year of business.
