In many broadcast facilities, the monitoring rack looks about the same. One box decodes SMPTE ST 2110, another handles MPEG-TS, and a third covers OTT streams. Each box has its own interface and its own license, and none of them share data with the others.
This is technical debt. Each of these purchases made sense at the time, but together they now limit what you can do next. The aging equipment is the part everybody sees, and there is more debt underneath it.
In broadcast monitoring, we see this debt in three places.
- Dedicated appliances do one job each, so every new format or standard means another device and another maintenance contract. Over time, the engineer ends up with five interfaces, five firmware update procedures, and five alarm configurations. During a live incident, every minute spent switching between those systems is a minute not spent fixing the problem.
- Many vendors charge per feature, per format, or per channel. If you want to move licenses between facilities or from one event to another, that means paperwork and waiting. Procurement moves slower than live production. For example, a license needed for a weekend event can still be waiting for approval when the event goes live, and the customer pays for that gap.
- Legacy systems probe the signals they understand and ignore everything else. When you add cloud playout or an OTT delivery tier, the existing tools don’t extend to cover it. Very often, engineers find out a stream was never monitored when it fails on air. For the business, that means lost ad revenue, missed SCTE-35 markers, and subscribers who leave.
What's adding to broadcast monitoring debt right now?
Two changes in the industry are making this debt harder to live with.
First, SMPTE ST 2110 is now the baseline. In Devoncroft’s 2026 Big Broadcast Survey, IP networking and content delivery ranked as the most commercially important trend for the sixth year in a row. Many facilities have already committed to IP. The problem is that if their monitoring was built for SDI, it doesn’t match the infrastructure it is supposed to watch. Meaning, the signals moved to IP, but the visibility stayed behind.
Second, there is MXL, the Media Exchange Layer. MXL lets media move in memory, in real time, between software functions on the same host and across hosts over RDMA, without rewiring any hardware. MXL traffic never hits the network, so a network probe can’t see it. So the monitoring you deploy for ST 2110 today also has to cover MXL workloads tomorrow, and it should do that on the same platform.
US operators also have a deadline. The FCC’s July 2026 order reallocates more upper C-band spectrum, with satellite relocation due by the end of 2030. This shrinks a traditional satellite distribution path and pushes more distribution to IP on a regulatory timeline. The relocation is reimbursed, but the IP side usually comes with no extra headcount and no extra budget.
How software can break the debt cycle
Replacing an old hardware box with a newer box just starts the same cycle again. To actually remove the debt, the architecture has to change. From our point of view, three things matter.
- Software on standard compute. With dedicated hardware, every change in format or resolution means rip and replace. When monitoring runs on commercial off-the-shelf (COTS) servers, you scale or add formats with a software allocation. For example, when a channel moves from HD to UHD, you reallocate resources on the server instead of buying a new box, so there is no new capex for hardware.
- One system for all formats. The same system should take in ST 2110, SMPTE 2022-6/7, MPEG-TS, HLS, DASH, CMAF, and legacy formats at the same time. If an incident starts in the IP core and shows up in the OTT tier, you want to follow it in one place instead of comparing timestamps across three tools.
- Open telemetry. When monitoring data stays inside each tool’s own interface, your team can’t use it anywhere else, and that is part of the debt too. The data should go directly into the tools the team already uses, like Grafana or Kibana.
In short, these are the criteria that decide whether a migration actually pays down the debt or just moves it somewhere else.
How the migration works in practice
Very few customers replace the whole monitoring chain in one step. A phased migration works better, and with software you can grow coverage without buying hardware you will remove later. In practice, it works in four phases.
Phase one is an audit. Look at where unmonitored signals, end-of-life appliances, and engineer workarounds cost you the most time and money. Which streams have no probe at all? Which appliances are out of vendor support? Where are engineers relying on a manual check?
Phase two is to deploy alongside the existing chain. TAG’s MCM runs on a standard server, in parallel with what you already have, and one software instance covers ST 2110, compressed, and OTT. You prove the coverage on live traffic before you remove anything.
Phase three is to consolidate. Once the coverage is proven, you start removing hardware. For monitoring and QC, QC Station replaces waveform monitors and vectorscopes in software, and Elastic Data connects to Grafana or Kibana, so monitoring metrics go straight into the dashboards your team already uses.
Phase four is cloud and OTT. You extend into cloud playout and OTT delivery with the same platform, whether it runs on-prem, in the cloud, or hybrid.
There is a cost to waiting to deal with tech debt
Every month a facility keeps its per-format appliances and works around license limits, the migration gets more expensive, because every format added in the meantime is one more box that will eventually need to be replaced. There is also a people cost. It’s the engineer who spends Friday on firmware updates and has less time to prepare for Monday’s event. And it’s the leadership team that can’t justify disruption this quarter, so the problem moves to the next one.
If this sounds like your facility, we’d be happy to show you how it works on your own signals.

Yes. TAG integrates with the key management systems of Verimatrix, Irdeto, Huawei, Axinom, buyDRM, Kaltura UDRM, and SKY CKS, and it supports AES-128, BISS-2, CENC, and DVB Simulcrypt CA systems. Decryption happens in real time inside a secure zone. This lets you monitor encrypted streams without any external decryption hardware.
TAG monitors IP signals natively. Many facilities in the middle of the transition run TAG on the IP side and keep their existing SDI monitoring until those SDI paths are retired. So you start with the IP segments, and as more SDI paths move to IP, the monitoring scales with them.
For US operators, the July 2026 order removes another 160 MHz of the C-band spectrum used for satellite distribution, so more distribution is moving to IP. With software-based monitoring, those new IP delivery paths are covered from day one, with no new hardware and no new procurement cycle.
