High-speed data transfer: internet technologies and ST 2110
The development of internet technologies and progress in optical communication lines in the recent decade has been phenomenal. It has led to many providers being able to offer long-distance data transfer rates from 10 to 100 gigabits per second with minimal latency.
High-speed media transfer is also becoming available to a broader user pool with the recent developments in the affordability of equipment supporting the ST 2110 standard. Using standard IP technologies and transferring data without compression significantly speeds up the media transfer and saves resources at all stages of video production.
ST 2110 media transfer advantages for sports broadcasting
In sports broadcasting, especially live sports events, high-speed connections are critical for real-time decision-making when using video refereeing systems. Recent progress in telecommunications has made them accessible both economically and technically.
Transferring data with minimal delay is particularly important if the video judging system uses a VAR center setup, i.e. the cameras on the arena are transferring data to a remote location where the video refereeing servers are installed. Thanks to uncompressed signal transmission of ST 2110, the server in the VAR center has a delay of only several tens of milliseconds between an event happening on the arena and the signal being received, ensuring near-instantaneous review capabilities.
Furthermore, the affordability of modern IP equipment that is used by ST 2110 significantly reduces the cost of system implementation. Previously, transmitting a compressed JPEG XS signal required equipment costing 5–10 thousand euros per channel, whereas using ST 2110 and standard communication equipment makes 200 euros per channel sufficient. This cost reduction has democratized access to advanced VAR technology, making it feasible for a wider range of sports organizations. At the same time, network bandwidth has become significantly wider, allowing for multiple simultaneous streams and enhanced data throughput.
New VAR server videoReferee® vR 2110 by SLOMO.TV
SLOMO.TV is expanding its portfolio of ST 2110 solutions with the launch of the videoReferee® vR 2110 VAR server.
The new server is designed to work natively with ST 2110, but it can also work with standard SDI video signals using Blackmagic Design converters, providing flexibility and compatibility with existing broadcasting infrastructure.
videoReferee® vR 2110 features
Connection simplicity: using standard telecommunications equipment and cables allows for significant cost reduction of the whole VAR system, while simultaneously increasing reliability.
Advanced redundancy: thanks to the "red" and "blue" subnetworks, uninterrupted operation even in case of component failure is ensured, which is attributed to using ST 2110.
Ease of use: due to simplified management, the system makes it possible for broader staff deployment, enabling employees with varying technical backgrounds to contribute effectively while maintaining high performance levels and reducing operational expenses.
Output flexibility: the equity of inputs and outputs gives the server the ability to have a large number of output signals: VARs and AVARs workplaces, Multiviewer outputs, RRA, graphics, OB van. Previously, this required large servers with a lot of additional cards, but now all this is implemented with a single server with two QSFP28 connectors, showcasing the remarkable advancements in hardware integration. This also simplifies the connection to broadcasting equipment and OB vans, streamlining the entire production workflow. The system allows both receiving and transmitting of the necessary signals, creating a seamless connection amongst all parties.
Single cable: if previously transmitting a lot of signals required a large pool of copper or optical connections, now transmitting 32 3G channels requires only one standard 100 Gbit optical cable. This consolidation of connections not only reduces cabling complexity but also minimizes potential points of failure.
Scalability: due to the fact that a single ST 2110 standard 100 Gbit cable supports up to 32 input and output signals, the user can increase the number of processed signals from minimal to 32 simply by changing the software license. This flexible approach caters effectively to organizations with varying operational scales and requirements. Through its modular design, the system provides the option to expand capabilities by incorporating additional software options to connect extra workstations, Multiviewers, and other system components, ensuring a customizable broadcasting solution. Furthermore, the system's modular design allows for easy upgrades and expansions as ST 2110 equipment continues to evolve, ensuring long-term viability and future-proofing investments in VAR infrastructure.
