BT TV uses the YouView platform, so offers Freeview channels via DTT along with YouView's additional on-demand content, as well as 30 extra entertainment channels (18 of which are available in HD), 9 extra children's channels, 11 movie channels (Sky Cinema), 5 live sports channels (BT Sport & Sky Sports) and other on-demand services delivered through IPTV. BT Sport channels are available in SD and HD through IPTV signals. BT Sport, ESPN and AMC from BT are available in non-fibre areas over IPTV using copper multicast where available. As BT TV transmits channels and content through IPTV, BT requires customers to sign up to the BT Broadband internet and phone service to use BT TV, with connection via BT's official router, BT Home Hub.
