Why interoperability, not signal quality, is the real challenge in IP media, and what we are doing about it
Sergio Ammirata Ph.D., Chief Scientist, SipRadius
One of the biggest challenges facing media professionals today is not signal quality, and it is not the creative toolset. Both of those are in a better place than they have ever been. The real challenge is interconnectivity: the ability to pick the best sub-system for each job and have those pieces work together, seamlessly and smoothly.
That used to be the easy part. It is worth understanding why it no longer is.
Where the industry came from, and where it is heading
For most of its history, the media industry moved content around using dedicated, purpose-built hardware. It was expensive and inflexible, but it had genuine strengths, and one of them was a simplicity of connection we came to take for granted. A BNC was a BNC. An XLR was an XLR. If you plugged an output into an input, it worked, because the connection carried a signal in a form both ends already understood.
The shift to IP and software has transformed that world for the better. It has opened up flexibility, scalability and reach that dedicated hardware could never offer, and it continues to move quickly. But it has also changed the fundamental nature of connection. A data stream is just a collection of ones and zeroes unless you also explain the format, the codec, the data rate, the error protection scheme, and the origin and destination. So today, if you plug an output into an input, the chances are very high that nothing will happen.
Having watched this industry evolve from one end of that journey to the other, we think the useful question is not which era was better, but which qualities are worth carrying forward into it. IP clearly represents the future. Plug-and-play connection, the confidence that things will simply work together, is high on that list. It is the one thing the transition to IP has yet to fully deliver.
This matters well beyond traditional broadcast. The attractions of an IP-and-software ecosystem, the ready availability of internet access, the scalability of software systems, the affordability of the supporting hardware, mean these capabilities now reach far into the wider AV world. Corporate users run virtual town halls and product launches. Conferences and events design richer, more engaging experiences. Houses of worship find new ways to bring their congregations together. All of them run into the same wall.
Standards are necessary, but not sufficient
The broadcast industry has always relied on standards, drawn up by respected bodies to ensure interoperability and quality. That work was thorough and detailed, and the results were strong and reliable. But software architectures are the very definition of agility, and the idea that the IT world will stand still while the industry agrees a universal set of media standards is faintly ridiculous.
None of this is to say there are no standards for IP connectivity. We have SMPTE ST2110, IPMX, NDI and Dante/AES67. We have RIST and SRT. We have NMOS. These are all genuinely good, and they are doing their job.
But compliance with these standards does not, on its own, deliver the goal every modern media professional actually wants: plug and play. You cannot simply assemble a set of best-of-breed components and expect them to work together. Each one still demands significant effort in discovery, routing and workflow before it becomes part of a coherent, practical system.
Introducing SipMX
That gap is the reasoning behind SipMX, the secure IP media exchange.
SipMX is a new super-layer designed to make media orchestration and multi-protocol interoperability simple, fast and secure. It is built on open standards including NMOS, RIST and IPMX, and it allows facilities running SMPTE ST2110, Dante/AES67, NDI and more to be discovered, routed and managed from a single control layer.
The point is that it sits above the protocols rather than replacing them. Users share streams transparently, even when each end is running different equipment from different manufacturers using different codecs and protocols. A broadcaster can walk into a college sports stadium and share feeds and sources without first working out who is responsible for transcoding and timing. The boundaries simply stop getting in the way.
SipMX also provides discovery and routing across any network, including navigating firewalls, cellular and internet connections, and cloud and hybrid architectures.
And as its name makes clear, security is not bolted on afterwards. SipMX imposes hardened, enterprise-grade security end to end, including an integral certificate authority, an EST server, zero-trust onboarding and public key authentication. We will not unpack the full mechanics here, but the principle is that the whole infrastructure is protected, not just its edges.
Already proven in the field
None of this is theoretical. The underlying technology behind SipMX is already at work in demanding, real-world productions, including:
- distributing live camera feeds at one of the world’s most prominent football events to 50 end points, from VIP viewing areas to multi-lingual commentary booths, with the very low latency such an environment demands;
- providing feeds for broadcast graphics, statisticians and analysts during Emmy-winning coverage of US elections;
- driving new content formats by shipping minimalistic remote production kits across North America, resulting in new and hugely popular spin-off brands.
Across these deployments, the same themes recur: production-quality video delivered over links as ordinary as LTE and VPN, transport over unicast UDP using only open standards, better than one-second glass-to-glass latency, and centralised management with full visibility of both content and production control paths.
This is a deliberately high-level picture. The intention here is to show what SipMX makes possible, not to document every mechanism behind it. If a particular capability is relevant to your work, that is exactly the kind of conversation we would welcome.
An open invitation: the SipMX Alliance
Technology like this only reaches its potential when the industry builds on it together. That is why the SipMX Alliance has been established.
The Alliance invites device manufacturers, software vendors, system integrators and cloud providers to collaborate in shaping future developments and driving industry adoption. To encourage active participation from as many organisations as possible, membership is free.
SipMX and the SipMX Alliance are initiatives aimed squarely at a fundamental problem, one that quietly limits creativity and connectivity, while continuing to support the proven, popular standards the industry already trusts. The goal is straightforward: to bring simplicity and scalability to every user, and to truly democratise media.
If any of this speaks to a challenge you are wrestling with, we would be glad to talk.
Join the Alliance.
Closing the gap
The shift to IP has given the media world more flexibility, reach and creative possibility than ever before. What it has not yet restored is the simple certainty that any two systems will work together. That is the gap SipMX sets out to close, bringing plug-and-play confidence across protocols, vendors and eras while keeping everything that makes IP the right foundation to build on. Interconnectivity was the real challenge we opened with, and it is one the industry is now well placed to solve, together.
