OB Truck (Outside Broadcast)

An OB truck is a mobile production facility—typically a large truck containing vision mixers, audio consoles, monitoring systems, Encoding Equipment, and all infrastructure needed to produce a broadcast from remote locations. The name "OB Truck" (Outside Broadcast) reflects that broadcast production traditionally happened inside fixed studios; an OB truck is the studio on wheels.

For large-scale events like the Esports World Cup, OB trucks provide complete production infrastructure without requiring venue AV systems. Instead of relying on venue equipment (which might be inadequate or unavailable), we bring our own integrated production facility. This gives us total control over quality, workflow, and failover systems.

A typical OB truck setup includes: multiple vision mixers (primary + backup), master audio console, monitoring systems showing every signal in production, graphics systems, encoding racks with multiple encoders, recording systems, comms (headsets and intercom), power distribution, and fiber termination points. The truck is self-contained enough to operate without venue infrastructure except for power and network connectivity.

The advantage is reliability and consistency. We know exactly what equipment we're working with. We've tested integration repeatedly. Failure modes are understood. When the production team arrives at the venue, setup time is predictable because we're integrating known equipment rather than unknown venue systems.

The disadvantage is cost. A mobile OB truck costs millions of dirhams to build, tens of thousands per deployment to maintain and staff, plus fuel and transportation. For a one-time event, this expense is justified only if production value is high enough to support the cost. For frequent events, OB trucks make economic sense.

For the Esports World Cup, we used an OB truck setup at the main arena and smaller mobile rigs at secondary arenas. The main OB truck coordinated all five arenas, managed redundancy, and handled the master broadcast signal. Secondary rigs handled individual arena production and contributed feeds to the main truck.

FAQ
Do all large events need OB trucks?
+
No. If venue infrastructure is adequate and reliable, deploying an OB truck is wasteful. We evaluate venue capabilities during Site Surveys. If venue has professional AV infrastructure, we integrate with it. If venue infrastructure is weak, an OB truck provides insurance against venue limitations.
How long does it take to set up an OB truck at a venue?
+
Typically 2-3 days for major events. This includes unloading equipment, connecting fiber/power/network to the venue, setting up camera positions, configuring mixing systems, testing failover, and rehearsing with talent. Time varies based on venue complexity and production complexity.
What power requirements does an OB truck need?
+
A major OB truck draws 100-200 amps at 3-phase power during operation. This requires dedicated power infrastructure. Venue electrical systems aren't always sized for this. During Site Surveys, we verify electrical capacity and plan power distribution. For inadequate venue power, we sometimes bring portable generators.
Can we use OB truck infrastructure for post-event storage and editing?
+
Sometimes. OB trucks have high-capacity storage and computing power. After event production ends, the truck can serve as a temporary editing suite for post-production if the venue is nearby. More often, footage is transferred to permanent storage systems before the truck leaves the venue.
