...power a live 4K production of a J League football match for SKY Perfect JSAT Corporation, the Japanese-based broadcasting network and J League rights holder. This unique trial has for the very first time made it possible to provide instant highlights and slow motion replays for a live 4K production.

From Kyodo’s OB truck at Japan’s Sendai football stadium, two EVS XT3 servers were used to manage the 4K multi-cam ingest, recording and playout operations, enabling instant replays, highlights packages and slo-mos for the live 4K broadcast of the J League football match over 200 miles away in Odaiba. This was made possible thanks to the unique 3G single link in and out configuration of the XT3 servers. The two XT3 servers (in a four in/four out configuration) provided the four 60p synchronized feeds needed for the world’s first 4K slomo trial. Kyodo Television controlled the 4K slomo operations using the XT3’s unique single link 3G SDI connectivity capabilities for ingest and playout . The two servers were linked through EVS’ live media sharing network and controlled using EVS’ Live Slow Motion (LSM) system. Kyodo Television recently invested in EVS’ XT3 server technology for its OB trucks. This enables them to switch seamlessly between SD, HD, 3D, 1080p and 4K live productions with just a simple reconfiguration of the server using the unique 3G in/out link. The success of this 4K 60P trial will enable the technology to be deployed for future large-scale productions.
