The Czech Philharmonic Symphony Orchestra broadcasts and live streams concerts to international audiences across a range of delivery platforms leveraging a 4K HDR production workflow comprising technologies like AJA FS-HDR, KUMO, HELO, 和Ki Pro Ultra 12
Prague’s Czech Philharmonic Symphony Orchestra has broadened its global footprint in recent years by transforming the Rudolfinum concert hall, where it performs, 通过视频直播和流媒体技术进入国际舞台. Rudolfinum Technical Supervisor Dušan Bajtoš is responsible for the venue’s production workflow, which supports concert broadcasts and streams to European Television channels Czech TV, MEZZO TV, ARTE, and European Classical TV; social streaming platforms like YouTube, Vimeo, and Meta; and many other distribution points. To ensure the highest quality experience across viewing platforms and device types, he opted to produce concerts in UltraHD HDR end-to-end and has come to rely on a host of AJA equipment for execution.
应聘这份工作的时候, 它是该地区首批超高清HDR项目之一, 我喜欢好的挑战,” Bajtoš said. “任何看过超高清HDR内容的人都能看到质量上的差异, not to mention that most consumers already have UltraHD HDR-capable displays at home, 所以这条路是有意义的. 使用像AJA FS-HDR这样的工具, we can raise the caliber of our signal output and deliver a viewing experience audiences can enjoy a lot easier.”
为全球观众提供每场演唱会的不同视角, the team leverages four manned cameras and six robotic cameras controlled from the director’s room on-site. 每场音乐会之前, 它们包括一个描述角度的射击列表, timing, 每台相机的镜头长度, 以及要聚焦的对象或艺术家. 从导演的房间里, 巴伊托斯和他的团队负责制作, leaning on a collection of displays to monitor the feeds and make color and exposure adjustment calls. 信号转换-相机日志格式之间, HDR and SDR, 超高清和高清-对每次传输都至关重要, 这就是巴伊托斯使用的地方 AJA FS-HDR. The HDR/WCG converter/frame synchronizer lets the team convert the output to match each delivery partner’s requirements, be it 4K HDR, HD HDR, or HD SDR.
“在采用FS-HDR之前, 我们的委员会测试了几种解决方案来评估转换的质量, 但都比不上FS-HDR,” he explained. “It wraps such an extensive range of algorithms into an affordable device and helps us meet nearly any conversion need. 我们也喜欢它提供的各种模式, 从Colorfront引擎直播模式到BBC HLG LUTs模式和NBCU LUTs模式, 哪个给我们留下了深刻的印象.”
除了FS-HDR，在整个制作过程中，bajtoski还利用了an AJA KUMO 1616 12G-SDI router, which is integrated into the robotic camera head system to support automatic camera switching. 该管道进一步使用 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 12G4K/UltraHD/HD recorder and player/multi-channel HD recorder is used for Apple ProRes backup recording.
“HELO has proven to be an incredibly reliable streaming and recording device that makes it easy for us to quickly share concert recordings for crew needs and director reviews. 就像我们所有的AJA装备一样，它很好用。.
