This project, in which a number of leading companies in the broadcast industry are involved, entails major challenges. The live broadcast will be based on full UHD 8K, Phase-2 content, captured at high quality, and then distributed on an 8Mhz bandwidth UHF multiplex. This means that not only will a 7,680 x 4,320 pixel resolution signal be transmitted. All the benefits of UHD will also be implemented: High Dynamic Range (HDR), Wide Colour Gamut (WCG), High Frame Rate Refresh Rate (HFR) and next-generation NGA audio.

SAPEC, a leading Spanish company with more than four decades dedicated to the design, development, and manufacture of cutting-edge solutions, is developing an 8K encoder built on equipment developed by Cisco. The initiative stems from a collaboration agreement between the RTVE-UPM Cátedra and the US company signed at the Mobile World Congress 2023 in Barcelona.

For this project, SAPEC will use all the knowledge it has on UHD and video compression, acquired over more than a decade with pioneering projects (such as the world's first Ultra High Definition broadcast in DVB-T2 with HDR, WCG and AC-4 content) and materialised in equipment prepared to work with this type of workflows, such as the modular SIVAC-ONE platform. As a matter of fact, SIVAC-ONE encoders have been the backbone of the UHD broadcasts promoted by the UHD SPAIN association since 2021, which were distributed via DTT, satellite, streaming and HbbTV, and culminated with the broadcasting of the Qatar World Cup in UHD.

The live DTT 8K broadcast will take place soon at the Official RTVE Institute, where the technical description of the pilot and the live demonstration of the initiative will be held. SAPEC has been a member of the Advisory Committee of the RTVE-UPM Cátedra since its foundation, participating in the planning and deployment of all technological pilots and preparing technical reports for the sector.
