The VB440 helps engineers validate IP workflows and accelerate product development

Pushing IP Forward: one lab at a time
As the broadcast world marches deeper into IP-based workflows, industry conversation tends to focus on high-profile deployments and on-air results. But quietly, behind the scenes, there’s another layer of activity that’s just as critical – and it’s happening in the labs. This is where future-facing technologies are built, tested and refined before ever reaching a production truck or broadcast chain. And increasingly, powering that testing is one of the industry’s best-kept not-so-secrets: the VB440 from Bridge Technologies.
The VB440 is already well established as a powerhouse in live production environments, delivering real-time, browser-based visibility across video, audio and network parameters – all over ST 2110. But beyond the studio floor or OB van, it’s finding a vital role in development labs, where engineers are stress-testing new gear, validating IP workflows, and preparing new products for market. These aren’t commercial deployments of the VB440 – they’re collaborative investments: lab units supplied by Bridge to select technology partners, supporting joint innovation that benefits the entire industry.
From encapsulation to audio processing systems to frame rate converters, every piece of IP production equipment has to prove it can walk the line – literally – when it comes to stream integrity and sync. That’s where the VB440 shines. It serves as the impartial referee and diagnostic toolkit, validating conformance and surfacing any issues in real time, across every domain of the signal path. Some Bridge partners are using VB440 units to ensure their frame rate conversion technologies work flawlessly with 2110 streams. Others are building audio tools and leveraging the VB440’s audio meters and AV sync readouts to verify accurate delivery. Some developers are using it to validate innovative technologies that represent the core of some of the globe’s largest performance venues. The applications for development are almost without limit.
It’s not just about specs and standards, though. It’s about visibility. What makes the VB440 indispensable isn’t just what it monitors, but how it presents it: a single tool, accessible via any HTML-5 browser, that gives up to eight users real-time, simultaneous access to video scopes, audio graphs, network metrics and more. Engineers value the probe because it replaces a rack’s worth of kit. Developers integrate it into their testing because it’s immediate and responsive. And teams find its central benefit in the collaboration potential it offers – not just internally, but with Bridge Technologies themselves.
Because the development process isn’t a one-way street, it’s an exchange. Often, Bridge and its tech partners trade units – a VB440 is swapped for a partner product – creating a feedback loop of mutual insight. It’s less of a vendor-customer relationship and more of a working circle: a collaborative ecosystem built on shared goals. And when these developers gather – at workshops, events, or just in the backchannel Slack chats – the VB440 is often the common reference point. A ‘secret weapon’ for those in the know.
Nowhere is this more evident than in the roll-out of VB440’s new AV Sync Generator. Audio-video synchronisation has long been one of the more painful aspects of IP production, particularly when video and audio are handled in separate streams. Tier One broadcasters have typically had the budget and hardware to keep it under control. But for everyone else, real-time, precise sync has remained elusive – until now.
The VB440 changes that with a software-based, browser-accessible AV Sync generator tool that’s accurate and scalable, and which takes a fundamentally different approach to sync monitoring, by physically embedding sync data in content as a ‘first line of defence’. In essence it embeds machine-readable electronic markers directly into audio signals and displays, in real time, the deltas between audio and video across potentially unlimited groups. Add in blink-and-beep indicators, colour bar tools, and API support for AI-driven sync management, and suddenly you’ve got a best-in-class sync platform built into a tool you already use. A crucial weapon in almost all ST2110 equipment development.
And that’s the point. The AV Sync generator is just one more example of how the VB440 brings extraordinary capability into a single, agile platform. Not a specialist box for one team, but a multifunctional production probe designed to support every stakeholder – from the colourist to the audio engineer, the network technician to the R&D developer.
Ultimately, Bridge Technologies’ aim isn’t just developing better tools. It’s creating conditions for better collaboration. By placing the VB440 into the hands of innovators and enabling them to build and test within real-world IP environments, Bridge is helping to raise the bar for everyone. Whether broadcasting live to millions or building the next-gen tools that will make that possible, it’s clear: the future of IP production doesn’t get built alone.
