Digital terrestrial television in the United Kingdom encompasses over 100 television, radio and interactive services broadcast via the United Kingdom's terrestrial television network and receivable with a standard television set. The majority of digital terrestrial television (DTT) services, including the five former analogue channels, are broadcast free-to-air, and a further selection of encrypted pay TV services are also available.

The Craig-Cefn-Parc transmitter is owned and operated by Arqiva.
The Mynydd Emroch television relay station is sited on the eponymous hill to the east of Port Talbot. It was originally built in the 1970s as a fill-in relay for UHF analogue television. It consists of a 25 metres (82 ft) self-supporting lattice tower standing on a hillside which is itself 600 ft above sea level.

It consists of a 25 m self-supporting lattice mast standing on a hillside which is itself about 180 m above sea level. The transmitters are beamed towards the southwest and northwest to cater for those digital terrestrial TV subscribers in Briton Ferry and western Neath which for reasons of geography can't get a signal direct from the Kilvey Hill transmitter at Swansea nor from the relay transmitter at Neath Abbey across the valley. The Briton Ferry transmission station is owned and operated by Arqiva.
