Japanese outside broadcast production company Kyodo Television has chosen server technology from EVS to 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 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 synchronised feeds needed for the world’s first 4K slo-mo trial. Kyodo Television controlled the 4K slo-mo 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. “EVS’ expertise in live sport production technology is the reason we selected their innovative servers for the core of our OB operation,” said Mr. Ishiguro at Kyodo Television. “For this high-profile trial we needed to be very confident we could maintain the same speed and reliability despite the huge bandwidth demands of 4K. Having EVS technology at the heart of our end-to-end 4K operation meant we could manage a full live 4K operation and deliver live instant replays, highlight packages and slow-motion functionality. We also have the peace of mind of knowing that the investment is future-proof, a key factor in a rapidly changing technology world.”www.evs.tv
