Abstract

The European Broadcasting Union and several of its member organisations undertook an ambitious trial over the summer period – a live, UltraHD, High Dynamic Range, High Frame Rate, Wide Colour Gamut and Next Generation Audio trial at the European Athletics Championships in Berlin, Germany. The trial included four 2160p/100 cameras with live control of shading/racking, live vision mixing, live recording, live mixing of audio objects, audio-visual synchronisation with audio objects and live encoding. This paper looks at the lessons learned during the trial – what went well, what needed extra work and what is needed to overcome current technical hurdles. This document was originally published at the SMPTE Technical Conference, 22-25 October 2018, in Los Angeles, California, USA, and subsequently in the SMPTE Motion Imaging Journal, Volume 128, Issue 3, April 2019 Additional key words: Ultra-high definition, UHD, high frame rate, HFR, nextgeneration audio, NGA, high dynamic range, HDR, hybrid log-gamma, HLG, wide colour gamut, WCG, BT.2020, high definition, HD, object-based audio, OBA, high-order ambisonics, HOA

欧洲田径锦标赛:来自直播、HDR、HFR、UHD和下一代音频体育赛事的经验教训

欧洲广播联盟及其几个成员组织在夏季期间进行了一项雄心勃勃的试验——在德国柏林举行的欧洲田径锦标赛上进行了现场、超高清、高动态范围、高帧率、宽色域和下一代音频试验。试验包括4台2160p/100摄像机，具有实时控制阴影/机架、实时视觉混合、实时录音、音频对象的实时混合、音频对象的视听同步和实时编码。本文着眼于在试验过程中吸取的教训——哪些进展顺利，哪些需要额外的工作，以及需要克服当前的技术障碍。本文档最初发表于2018年10月22日至25日在美国加利福尼亚州洛杉矶举行的SMPTE技术会议上，随后发表于2019年4月的SMPTE运动成像杂志，第128卷第3期。附加关键词:超高清，超高清，高帧率，HFR，下一代音频，NGA，高动态范围，HDR，混合对数伽马，HLG，宽色域，WCG, BT.2020，高清，高清，基于对象的音频，OBA，高阶双声，HOA
