Spain: RTVE live broadcast in Dolby Audio, Dolby Vision

July 7, 2017

RTVE has become the first national channel in Spain to complete a live broadcast in Dolby Audio and Dolby Vision. On July 5th, the historic Solemn Changing of the Guard ceremony was broadcast live in Dolby Vision High Dynamic Range (HDR) technology and Dolby AC-4 sound, using the 4K DVB-T2 trial channel that is operated by RTVE and Cellnexx Telecom. This transmission was available on terrestrial channels in Madrid (channel 32), Barcelona (channel 43) and Seville (channel 36), and viewers with a 4K HDR TV could receive the transmission.

To successfully deliver the broadcast, set up included two outside broadcast trucks; one for video and one for audio, as well as a cabin that was installed with EVS recorders for the video production, camera control units and reference monitors and analysers, as well as all the necessary Dolby equipment to incorporate Dolby Vision and Dolby Audio technologies. A satellite uplink was created to distribute the signal via Hispasat’s satellite to Barcelona and Seville.

The broadcast was also supported by Dolby’s partners Loewe, LG, Cellnex, Albala, Abacanto, Grass Valley, Crosspoint, Moncada y Lorenzo, Canon and Huri and was made possible thanks to a collaboration with the National Heritage and The Royal House. Technical partner Ateme provided encoders to help generate the video and audio streams including the dynamic metadata provided by Dolby`s equipment to deliver Dolby Vision HDR.
