Ericsson recently demonstrated how live UHDTV could be enabled via a next-generation delivery system during the European Broadcasting Union (EBU) Production Technology Seminar in Geneva, Switzerland. The demo, focused on interoperability and using Ericsson technology to receive an off-air feed of a 4:2:0 file-based system and receive and decode as 4K UHDTV, showed how high quality fast moving images can be captured for sports and live action broadcasting, which are seen as a key driver for the uptake of UHDTV.
Central to both parts of the 4K UHDTV demo was the ‘Simulsync' synchronisation technique, the technology used by Ericsson to accurately synchronise the left and right channels of 3D contribution feeds. In this case, the UHDTV 4Kp25 content feed was split into four 1080p25 quadrants, synchronously encoded into MPEG-4 AVC and transmitted. Four receivers, in phase lock, decoded the received bitstream to reproduce the 4Kp25 content feed.
