Last weekend the Catalunya Grand Prix took place in Barcelona, seventh round of the 2019 MotoGP World Championship. During the three days of the event, shooting tests in 4K-HDR format were completed in anticipation of broadcasting activities. Specifically, our unitONE has provided, as host broadcaster, the shooting of the track activities (track-feed) providing in multicast, without any conversion, the process of the 27 cameras (SONY HDC4300) in the 4K-HDR (S-log3Live) formats and HD-SDR. The latter is intended for the current transmission of all right holders. Thanks to its great capacity and flexibility, the unitONE has also managed all the activities of MCR IPF (International Program Feed) to make available the different formats required by the various broadcasters: 4K-SDR, 4K-HDR (HLG), HD-HDR ( SLG). Sixteen EVERTZ 7814UDX-AES8-3G-F-2 and four SONY HDRC4000 units were used for the impressive gluing activities. For the occasion, a viewing room had been set up with two SONY BVM-HX310 and two BVM-E171 monitors.
