How We Guarantee Project Success
1. Needs Analysis & Concept Design
We analyze your operational workflows, space constraints and camera counts to design custom 2D layout schemes and weight distribution profiles.
2. Mechanical & Coachbuilding Engineering
World-class coachbuilding: We design robust chassis modifications, hydraulic expanders, and environmental isolation layers.
3. Infrastructure & Signal Flow Integration
Complete cable management, rack elevation plans, power distribution schemes and signal topologies built on strict SMPTE/EBU standards.
4. Acoustics, HVAC & Power Calculations
Precision air-flow calculations to protect sensitive hardware and guarantee silent, climate-controlled operator environments in any region.
5. Rigorous FAT (Factory Acceptance Testing) & Handover
Every unit undergoes stress testing under maximum load (heat, signal integrity, power stability) before dispatch. We do not deliver until full compliance is proven.

FAQ
How does AVITENG approach thermal management and HVAC design in expanding OB trailers?
A: HVAC capacity in AVITENG OB trailers is calculated based on total internal BTUs generated by broadcast hardware (power supplies servers, CCUs, switchers) combined with extreme ambient temperature conditions. We integrate multi-zone, redundant (N+1) low-noise HVAC systems with independent airflow paths for equipment racks and operator zones, ensuring zero thermal throttling during live broadcasts.
What broadcast network topologies and IP standards are supported in AVITENG OB units?
A: AVITENG designs mobile units supporting Native IP (SMPTE ST 2110 for uncompressed video/audio, ST 2022-6, and ST 2059 PTP timing), NDI workflows, and traditional 12G-SDI / 3G-SDI hybrid architectures. We utilize NMOS (IS-04/IS-05) open standards for dynamic device discovery and routing management.
How is structural integrity and weight distribution managed in custom coachbuilding?
A: Vehicle engineering includes rigorous axle load distribution analysis, low-center-of-gravity placement for heavy rack power systems, and heavy-duty single/double hydraulic expansion mechanisms. Structural frames are built with acoustic insulation rated for broadcast-grade noise isolation and high thermal efficiency
