The increasing availability of Ultra HD displays in the consumer market combined with the acquisition of exclusive European football television rights created the ideal opportunity for BT to launch Europe's first live sports Ultra HD channel; BT Sport Ultra HD. This ground breaking new channel went live on the 2nd August 2015 and since then has broadcast a wide range of sports, including Premier League and Champions League football, European and domestic rugby, PSA squash, NBA basketball and the world's largest UHD OB to date, the British Moto GP from Silverstone. The technology for live UHD production was in its infancy when BT started the project. The first productions used separate UHD and HD production units, but as the season developed increasing numbers of cameras have been shared. This paper will describe how new technical approaches and production values have enabled several broadcasts to be delivered using a single Outside Broadcast (OB) truck delivering all the UHD, HD and SD requirements. This paper also describes the many innovations introduced in the end-to-end ecosystem for the capture and delivery of Ultra HD including contribution networking, playout technology, HEVC encoding, broadband distribution and Set Top Box.
