With Imagine, tcp became the first Swiss provider to broadcast a live sports event from a SMPTE ST 2110, full-IP, uncompressed UHD HDR OB truck.
客户简介
tpc is the leading broadcast service provider in Switzerland. An independent subsidiary of Swiss national public broadcaster SRG SSR, tpc is responsible for production and technology for SRF (Schweizer Radio und Fernsehen), managing live production for a broad range of major national and international events — from football and Alpine skiing to theater and opera.
“It is great to see our new UHD1 truck on the road, giving us both outstanding production quality and valuable experience in developing and operating IP networks. Most important, it does all this while looking and feeling like the trucks that our crews have been operating for years.”
Build an outside broadcast (OB) truck capable of meeting today’s cost efficiency and production quality requirements, including HDR UHD, and of evolving to accommodate future market demands. With additional plans to build a new, IP-based facility in Zurich, tpc also wanted to use the truck as a learning exercise on how to construct and operate IP infrastructure.
A strong advocate of open standards, tpc chose to construct their new truck to support uncompressed UHD IP production using SMPTE ST 2110.
At the core of tpc’s UHD1 is Imagine’s Selenio™ Network Processor (SNP), which serves as both an SDI-to-IP gateway and low-latency, all-IP signal processing platform. It processes uncompressed UHD over IP using ST 2110, supports HD/UHD and SDR/HDR conversions, and assures optimal timing of IP signals for interoperability with all other compliant equipment in the truck. The SNP feeds into commercial off-the-shelf switches from Arista Networks using QSFP28 ports over 100GbE links.
tpc uses Imagine’s EPIC™ MV multiviewer with the SNP to monitor the signals of multiple screens, with inputs and monitor outputs all in IP. SNP makes a “proxy” signal from every UHD signal it touches, and EPIC MV uses these proxy signals — which are full-color, full-frame-rate, and typically HD resolution — rather than the UHD original, resulting in a significant reduction in overall system cost.
Connectivity of all Imagine and third-party devices, both SDI and IP, is managed by the Magellan™ SDN Orchestrator software control system, allowing tpc personnel to switch seamlessly between HD, Ultra HD and uncompressed real-time SMPTE ST 2110 streams.
现在，tpc 拥有了一辆面向未来的转播车，在未来许多年里，它仍将处于移动制作的最前沿。灵活的 IP 架构与视频格式和分辨率无关，能够无缝集成最新的压缩方案和画质增强功能。
与基于 SDI 的解决方案相比，SMPTE ST 2110 规范使 tpc 能够将视频、音频和辅助数据分成单独的离散数据流，从而提高效率和灵活性。此外，纯 IP 方法降低了 SDI 或混合 SDI-IP 环境的布线和功耗要求。
UHD1 以 IP 为核心，针对 UHD（使用标准或高动态范围）进行了优化，但仍能处理基于 SDI 的信号。通过处理未压缩和基于标准的 UHD 信号，tpc 能够处理视频信号，以满足所有客户的偏好，而无需夹层压缩方案，同时最大限度地提高视频质量并减少延迟。
最重要的是，tpc 的工作人员能够快速掌握新一代技术，因为它具有与传统 SDI 系统相同的性能特点和操作外观，同时还具有 IP 连接和软件灵活性的所有优点。
