Grass Valley Technology Drives New Concept in OB Truck Design

Why It Matters

On‑site processing slashes bandwidth costs and hardware complexity, enabling faster, more flexible remote productions for broadcasters.

Key Takeaways

• On‑site processing reduces bandwidth to ~100 Mbit/s.
• Grass Valley AMPP servers handle switching, replay, audio, multiviewer.
• Remote control rooms in Helsinki and Hilversum manage production.
• Supports 16 Grass Valley cameras and 32 SDI inputs.
• Smaller hardware footprint versus traditional OB trucks.

Pulse Analysis

The broadcast industry is accelerating its shift from centralized, hardware‑heavy remote production to decentralized, software‑centric workflows. By embedding Grass Valley’s AMPP platform directly in the OB truck, DMC Production eliminates the need for high‑capacity uplinks, delivering a multiviewer stream that consumes only about 100 Mbit/s of standard internet. This low‑latency approach not only reduces transmission costs but also simplifies the network architecture, allowing remote operators to work from control rooms in Helsinki or Hilversum with the same visual layout as on‑site staff.

At the heart of the new vehicle are AMPP servers that consolidate video switching, replay, audio mixing, and multiviewer generation into a single, scalable environment. The hardware footprint shrinks dramatically; three workstations and a modest rack of servers replace the bulky mixers and routers of legacy OB trucks. The system accommodates up to 16 Grass Valley cameras via XCUs and 32 external SDI feeds, while optional Calrec audio integration and a future NAS add flexibility for more complex productions. Remote teams interact through WebRTC and SRT, sending control commands back to the truck, which maintains a consistent production experience across locations.

For broadcasters, especially those covering live sports, the solution promises faster deployment, lower transport costs, and the ability to scale production resources on demand. It exemplifies the broader industry trend toward software‑defined, service‑oriented infrastructure, mirroring transformations seen in cloud computing and media asset management. As more events demand high‑quality, real‑time delivery without massive bandwidth, solutions like DMC’s AMPP‑powered OB truck are poised to become a new standard in live‑event production.
