The Dutch National Opera and Ballet offers a vast repertoire combining the Dutch National Opera, Dutch National Ballet, and the Holland Symfonia. To immerse visitors to its theater needed a new, future-proof audiovisual system to meet the necessary system requirements. The Dutch National Opera and Ballet leveraged SDVoE technology for a network-based system to bridge audio, video and other components while promoting flexibility for future enhancements. 

The Theater

Nestled in the heart of Amsterdam, at a bend of the Amstel River, a historic theater complex is home to the city hall of Amsterdam and the Dutch National Opera and Ballet. The theater, which opened in September 1986, features various rooms, including an auditorium with 1,600 seats across three levels, a foyer boasting a panoramic view over the Amstel River, and additional smaller private rooms and studios for private events and rehearsals.

The Dutch National Opera and Ballet creates, produces and presents national and international performances in opera, ballet, and related musical and dramatic arts. It  combines song, dance, music, acting, language, technique, and design to create a captivating live interpretation of human emotions. 

The existing audiovisual equipment, which included a composite video analog system, was as old as the theater. “In 1986, analog video technology was the preferred and only route for audiovisual systems," explained Rutger Flierman, video engineer and programmer for the Dutch National Opera and Ballet. "We’re leveraging real-time video transmission of the conductor camera to the theatre including stage management, fly-bar operators and off-stage singers and orchestras. Over the years, the Dutch National Opera and Ballet introduced new components to enhance the video quality, but, unfortunately, the new devices introduced latency. Additionally, the user experience became increasingly complex as new components were added to the audiovisual system.

“Unfortunately, the cabling in the theater became too old to transport high-definition images across long distances throughout the theater. As a result, the image quality declined, and the stage managers and performers could not view the conductor in a high-quality, latency-free live video feed.”

SDVoE Technology Exceeds Requirements

Ultimately, the Dutch National Opera and Ballet determined that many of the components had reached the end of their lifecycle; therefore, a new, future-proof audiovisual system would meet the necessary system requirements. 

The Dutch National Opera and Ballet required a system with low latency and a high-resolution and refresh rate. Fortunately, the SDVoE Alliance exceeded the Dutch National Opera and Ballet’s requirements.

“The future is network-based," said Flierman. "The flexibility of a network-based system enables us to add new devices in the future if the needs or the system requirements change. I began researching network-based audiovisual systems, leading to the SDVoE Alliance. I was intrigued by the SDVoE Alliance’s free online courses, so I started taking their online designer courses. It gave me access to outlines and documentation necessary to build a network-based audiovisual system. Plus, the entire course is free.”

Flierman applied his knowledge from the SDVoE Academy to design a network-based audiovisual system. Together with Will Hoogervorst Engineering (WHE), the team searched for cameras, monitors and a complete audiovisual solution to switch and fade the image to completely black. This was achieved by a modification of the screens and the ability to send black video from any SDVoE-powered receiver device.

As a result, the Dutch National Opera and Ballet leveraged the SDVoE Alliance’s ecosystem, including over 700 solutions designed to integrate seamlessly and flexibly to create an end-to-end hardware and software platform for audiovisual distribution. The SDVoE Alliance’s network architectures are based on off-the-shelf Ethernet switches, which provided the Dutch National Opera and Ballet with substantial cost savings and greater system flexibility and scalability over traditional approaches, such as point-to-point extension and circuit-based AV matrix switching. Notably, the SDVoE Alliance’s open API allowed the Dutch National Opera and Ballet to exercise their creativity to create a customizable user interface for administrators, technicians and stage managers, allowing them to access multi-view, picture-in-picture content, remote camera control, audio and fade to black.

After thorough testing the new, low-latency monitor system was implemented in 2023, at the beginning of the theater season, and all users, including conductors and singers, are very pleased with the huge improvement and outstanding performance. SDVoE technology, as implemented through the SDVoE Alliance’s members, provided the Dutch National Opera and Ballet with a future-proof solution for high-resolution, low-latency video distribution across the theater. The Dutch National Opera and Ballet can maintain the audiovisual system, create customized user interfaces built to the specific needs of the theater, and implement new technologies by leveraging the flexibility of SDVoE technology.
