The live streams will be sent via satellite from Brazil, and then distributed via Digital Terrestrial TV (DTT) and Internet Protocol (IP) but only to a handful of UHD TV sets in selected BBC Research and Development facilities.
------
The 4K pictures will be recorded by Sony in Brazil and sent back to the UK via satellite, but will only be used for internal testing and not available for viewing by the British public.

The BBC will be testing the use of High Efficiency Video Coding (HEVC) for broadcast distribution over Digital Terrestrial Television (DTT) and online. They will also be looking into the effectiveness of the MPEG-DASH adaptive bitrate technology.

Matthew Postgate, Controller, BBC R&D, said:

“BBC R&D has an outstanding track record as a catalyst for bringing the industry together and delivering the future of television to audiences. These trials are an excellent example of that tradition as a major technical achievement, such as distributing UHD TV over DTT and IP simultaneously from Rio, can only be made possible by close collaboration with a range of organisations. The trials will prove hugely valuable in furthering our understanding of UHD technology, and potential distribution models for the future, as well providing real benefits for licence fee payers in the near-term.”

Astra 19E 11406V UHD testid. TBS arvutituuner ja DVB Viewer Elecardi H265 koodekiga. Dekodeerib vaid mõne üksiku i-frame. Probleem ei ole hetkel arvuti jõudluses, vaid mingis ahelas koodekiga seoses. Lihtsalt ei "haagi" pidevaks pildivooks ära, kuigi 2GHz prose seda arvatavasti välja ka ei vea. Koodek on 2013. aastast ja kuidas see üldse arvutisse on jõudnud, on müsteerium ; võib-olla uuema versiooniga saaks parema tulemuse. Lentoid on ka, kuid sellega jääb pilt mustaks.
