捷克爱乐交响乐团利用包括AJA FS-HDR等技术在内的4K HDR制作工作流程，通过一系列交付平台向国际观众播放和直播音乐会, KUMO, HELO, and Ki Pro Ultra 12
布拉格的捷克爱乐交响乐团近年来通过改造鲁道夫音乐厅扩大了其全球足迹, where it performs, into an international stage via live video broadcast and streaming technology. Rudolfinum技术主管Dušan bajtoski负责场馆的生产流程, 它支持音乐会广播和流媒体到欧洲电视频道捷克电视, MEZZO TV, ARTE, and European Classical TV; social streaming platforms like YouTube, Vimeo, and Meta; and many other distribution points. 确保跨观看平台和设备类型的最高质量体验, 他选择端到端用超高清HDR制作音乐会，并开始依赖大量AJA设备来执行.
“When approached for this job, it was one of the first UltraHD HDR projects in the region, and I like a good challenge,” Bajtoš said. “Anyone who has watched UltraHD HDR content can see the difference in quality, 更不用说大多数消费者家里已经有了支持超高清hdr的显示器, so this path made sense. With tools like AJA FS-HDR, 我们可以提高信号输出的质量，提供观众更容易享受的观看体验.”
为全球观众提供每场演唱会的不同视角, 该团队利用了四台载人摄像机和六台由现场导演室控制的机器人摄像机. Ahead of each concert, they comprise a shot list that describes the angle, timing, and length of shots per camera, as well as the object or artist to be put into focus. From the director’s room, Bajtoš and his team execute the production, 靠在一组显示器上监控画面，并进行色彩和曝光调整. Signal conversion – between camera log formats, HDR and SDR, and UltraHD and HD – is crucial to each transmission, which is where Bajtoš uses AJA FS-HDR. HDR/WCG转换器/帧同步器允许团队转换输出以匹配每个交付合作伙伴的需求, be it 4K HDR, HD HDR, or HD SDR.
“Prior to adopting FS-HDR, our committee tested several solutions to assess the quality of conversion, but none compared to FS-HDR,” he explained. “它将如此广泛的算法封装到一个负担得起的设备中，并帮助我们满足几乎任何转换需求. We also love the various modes it offers, 从Colorfront引擎直播模式到BBC HLG LUTs模式和NBCU LUTs模式, which has really impressed us.”
In addition to FS-HDR, across productions, Bajtoš also leverages an AJA KUMO 1616 12G-SDI router, 哪一个集成到机器人摄像机头系统中以支持自动切换摄像机. The pipeline further uses an AJA HELO H.264 video streamer and recorder for reliable recording to USB drives that can be handed off to the crew and director after the production wraps. An AJA Ki Pro Ultra 12GApple ProRes备份录音使用4K/UltraHD/HD录像机和播放器/多声道高清录像机.
“HELO已被证明是一款非常可靠的流媒体和录音设备，它使我们能够轻松地快速分享音乐会录音，以满足工作人员的需求和导演的评论. Like all our AJA gear, it just works,” concluded Bajtoš.
