Vatican City in Ultra High Definition
VATICAN CITY: Working alongside Centro Televisivo Vaticano (CTV – Vatican Television Centre) as well as several other technology partners, Sony recently facilitated the global production and broadcast of the Ceremony of the Closing of the Holy Door by his Holiness Pope Francis in 4K High Dynamic Range (HDR). The ceremony brought to a close the Extraordinary Jubilee of Mercy, which began in December 2015.
CTV made use of 12 Sony HDC-4300 4K HDR cameras to cover the event, in addition to an HDR S-Log3 system for the live production. The broadcaster’s workflow simultaneously delivered a feed in 4K Ultra High Definition (UHD) with Standard Dynamic Range (SDR) and another in High Definition (HD) with SDR. The manufacturer’s MVS-7000X production switcher and the PWS-4400 replay server system also supported the workflow.
A Hybrid Log-Gamma (HLG) profile was used for broadcast delivery. This is an HDR standard that was approved in July by the International Telecommunication Union (ITU) and was used in the test broadcast of the Opening of the Holy Door, back in December 2015.
‘For the first time ever in history, we see a live television broadcast of Papal ceremonies in Ultra High Definition with High Dynamic Range, which ensures the highest quality of images available today,’ notes Dario Edoardo Viganò, prefect of the Secretariat for communications for the Holy See. ‘This is a state-of-the-art set up that reflects Pope Francis’ aim to keep up to speed with the rapid developments in global technology, to support the Catholic’s Church communication mission.’
‘A live production workflow called "SR Live for HDR" was used at this historic event,’ adds Peter Sykes, strategic technology development manager at Sony Professional Solutions Europe. ‘The production infrastructure is based on Sony's S-Log3 transfer function for simultaneous creation of 4K HDR and HD SDR pictures of the highest quality.’
‘We continue to work closely with CTV to develop and provide technology that supports its mission to capture all activities of the Pope and the Holy See, through immersive images that have the highest emotional impact possible,’ concludes Benito Manlio Mari, country sales manager, Sony Europe. ‘This is the first live POC (proof of concept) 4K HDR S-Log3 production by CTV, showing how a single production line can support distribution of multi-format broadcasts.’
