B u lga ria P av ilio n COMPANY: VIOSO Photos : MP- S t ud io.
The Bulgarian pavilion delivered the ‘wow’ factory courtesy of a memorable, tech-driven experience created by MP-STUDIO, a Sofiabased experiential company known for its expertise in 3D projection mapping and visual effects. With audiovisual technology at the heart of the installation, MP-STUDIO turned to its trusted partner, Vioso, to supply the systems that would bring the vision to life. The exhibit was divided into three main sections: ‘The Past’, ‘The Present’, and ‘The Future’. The Past embraced the analog charm of history, showcasing Bulgaria’s rich cultural heritage through traditional display methods. The Present transitions visitors into the digital realm, powered by EXAPLAY running on Vioso’s newly launched Anystation Pico players. These ultra-compact devices each output two WUXGA signals, allowing just seven units to seamlessly drive 14 wall-mounted monitors. A central Pico server handled synchroniaation via OSC commands, enabling smooth playback across a single expansive canvas, or multiple independent video streams. The Future presented the most dynamic and innovative part of the pavilion – a fully immersive space where visitors interact with their surroundings and contribute ‘messages for the future’. Spanning an area of 160 sq m, the environment relied on Vioso’s ProjectionTools autocalibration software and four calibration cameras to achieve a flawless blend across 14 projectors.

GPU, powered EXAPLAY to deliver four 4K signals via HDBaseT matrix switchers, ensuring crisp, synchronised visuals. What truly set the experience apart was its use of AI. Visitors scan a QR code to submit their messages via a website, which then relayed them to an AI system that generated real-time responses. These were instantly displayed on screen using NDI to feed content directly into the EXAPLAY playback engine. At the conclusion of the Expo, all visitor messages can be collected to form a digital archive of collective hopes and ideas for the future. Reflecting on the installation, Marin Dimitrov, CEO of MP-STUDIO TECH (the AV division of MP-STUDIO), said: “We are proud to be among the first to implement such a large-scale setup using Vioso’s new Pico servers and EXAPLAY platform. “We pushed the software to its limits and were genuinely impressed by its performance. EXAPLAY provided everything we needed – playback, timelines, NDI and OSC control, and synchronisation – all without the complexity of larger media servers.” Raul Vendeburg, Executive Director of Vioso, who was on-site during the installation, shared his enthusiasm for the project: “It’s incredibly exciting to see our new EXAPLAY solution play such a central role in the pavilion,” he said. “We developed it to offer a streamlined, user-friendly interface that covers the majority of needs in installations like this – while still supporting advanced capabilities like HAP-encoded content playback.” www.vioso.com
