Broadcast & ProAV Equipment Testing
IP-based broadcast and ProAV devices can fail at scale in real networks. Traffic contention drops frames, PTP drift breaks lip-sync, and multicast routing – these issues are systemic, hard to reproduce, and expensive to fix after deployment.
Promwad engineers validate your product as a complete system — video, audio, network, and control tested together under real load with mixed-vendor systems, multicast delivery, and 24–48h endurance runs — not just lab scenarios.

Why Testing Matters in Broadcast & ProAV
Broadcast and ProAV devices can fail in real IP networks — under real traffic, real synchronization demands, and real load — risking deployments and generating support tickets.
That is why we validate common failure patterns:
That's why we don't run isolated device checks. We validate what actually matters — network behavior under contention, time synchronization and lip-sync accuracy, multicast delivery and discovery, and long-run stability over 24–48 hours or more.
Do you want to ensure predictable behavior in real IP networks: interoperability, timing, and stress scenarios?

Business Impact
Where we plug in
We engage at every stage of the product lifecycle: design validation and test strategy setup, pre-production validation, certification and customer acceptance support, field issue reproduction, and scaling when you add more endpoints or move to a new topology.
What this means for your business
Testing at the system level — before your customers do
✓ Reduced support costs and customer-facing risks
✓ Accelerated time-to-market for new features and firmware releases
✓ Prevented failures in live production and fewer escalation tickets
✓ Independent validation and test reports for Tier-1 broadcasters
Who This Testing Is For
This service is built for teams that design, build, and integrate IP-based AV products — and need those products to behave predictably in customer networks:
ProAV product manufacturers, broadcast equipment vendors, and system integrators — particularly CTOs and R&D leaders who need to boost performance, migrate from SDI to IP without breaking schedules, and verify modern standards across mixed-vendor ecosystems.
When it's needed:
Need to launch ST 2110, NMOS, or NDI support but lack the internal test infrastructure?
We close that gap — so you can ship on schedule and show stable demos at NAB or IBC.
What Exactly We Validate
We organize testing around customer-facing capabilities — not raw protocol lists. Six areas cover the full behavior of an IP AV product.
Interoperability
Behavior across different source types, decoders/endpoints, and the full protocol stack — plus switching behavior. We reproduce the integration-killers: EDID mismatches that leave a screen black, color-space incompatibilities (YCbCr vs. RGB), and latency differences between devices.
Result: Confirmed compatibility across mixed-vendor ecosystems with evidence of how your device negotiates and switches in a real pipeline.
Media behavior
Video checked for jitter, packet loss, freeze frames, macroblocking, resync delay, adaptive-bitrate transitions, and resolution/frame-rate changes. Audio checked for dropouts, correct resampling (48 kHz vs. 44.1 kHz), and A/V drift, including lip-sync across synchronized, multi-device environments.
Result: Video and audio quality verified under real conditions, so degradation is caught before it reaches a live channel.
USB, KVM & peripheral interactions
USB validated for HID devices, redirection latency, and isochronous devices (webcams, audio interfaces). KVM validated for switching speed, USB state preservation, and hot-plug behavior. We target the field classics: keyboard lag after a switch, USB reconnect delays, and lost HID state.
Result: Peripheral and KVM paths validated the way operators actually use them, so integrators don't inherit the "keyboard died after I switched users" ticket.
Network readiness
Stream stability in real switching environments with actual traffic. Multicast behavior and predictable delivery under load. Segmentation and prioritization patterns used in production AV networks.
Result: Verified compatibility across mixed-vendor ecosystems — with evidence of how your device behaves in a real pipeline, not just in isolation. Multicast delivery and discovery confirmed under load, so integration issues surface in our lab, not at the customer site.
Performance & stability
Latency and stability under sustained load. Endurance runs of 24–48 hours or longer where required. Power behavior for PoE-powered deployments — including edge cases around power cycling and recovery.
Result: Traffic contention scenarios tested and documented. Line-rate performance validated. Bottlenecks identified under realistic network conditions — before they become field escalations.
Control & UX
Web UI, API, and CLI reliability — the paths integrators depend on daily. Companion apps and control workflows. Control-path stability during extended operation, because a UI that locks up after 12 hours is a deployment risk.
Result: Validated control paths across all interfaces — Web, API, CLI, and companion apps — under real session lengths. Your integrators get a product that stays responsive, not one that needs a workaround after overnight operation.

Case Studies
Automated testing for AV configurations
Challenge: A client needed to validate a large number of video and audio combinations across their product line — a task that would take 24–27 hours to execute manually.
What we built: An automated testing framework that runs the full cycle per combination: firmware update, device configuration, setup verification against the declared parameters, and error-free operation check.
We also developed a custom audio test bench that injects a test signal at the input and validates the output across 10 interfaces simultaneously. Manual testing was used selectively — only for urgent scenarios during active development.
Test equipment used: PRISM, MultiView 4, QxL, and SPG8000A.
Results: 3,000 test scenarios executed in 4 hours. Significant reduction in repetitive manual configuration and validation work.
IPTV/OTT platform testing
End-to-end testing of a complete IPTV/OTT solution — from backend middleware and sub-system integrations (CRM, billing, media server).
Prototype testing, test case development, clean installation and update flows, smoke testing, full functionality checks, and extended test cycles for both web and mobile clients.
Covered TV applications across seven platforms: Web, LG, Samsung, Android TV, Android, iOS, and Fire TV.
Tools used: Tizen Studio, Web OS TV IDE, Android Studio, Visual Studio Code.
IP camera test environment
Scope: Building a dedicated test environment for IP camera firmware and cloud integration.
What we covered: API-level testing through a cloud interface. Scripted validation of camera interfaces and modules. Cloud server workflows including install, update, and stress testing under sustained load.
