Real-time latency across your media supply chain

See inside your live media path —
to the millisecond.

TVU Chronos places lightweight probes along your live signal path and correlates the actual frames between them — measuring end-to-end and point-to-point latency, drift and sync in real time, across contribution, cloud production and distribution.

Cloud media processing is a black box.  Not anymore.

Open the black box

Probes through your media process — not just at the ends

Glass-to-glass tools time the whole journey. The moment your signal enters the cloud — production, transcode, packaging, distribution — it disappears into a black box, and you can't tell which stage added the delay. Chronos drops a probe at each boundary and correlates the frames between them, so every stage reports its own latency in real time.

The blind spot

Everyone watches the player. Nobody watches the path.

Player-side QoE tells you a viewer rebuffered — minutes later, at the edge. It can't tell you that cloud production added 214 ms last Tuesday, or that two feeds drifted out of sync before the encoder. Chronos measures the signal itself, between the points you choose, while it's happening.

Player-side QoE

  • Measures the viewer's session
  • Aggregate, after the fact
  • Can't localize where time was added

Latency is invisible until it isn't

A frame leaving the venue and the "same" frame downstream are never byte-identical — re-encoding, scaling and re-timestamping see to that. Chronos fingerprints frames and correlates them across probes, matching them and measuring true delay even after the signal is transformed.

◷

A live clock on your whole chain

One dashboard, every hop, updating in real time — with alerts when a stage slips.

How it works

Three steps to a live latency map

No SDK in your media, no changes to your encoders. Probes observe; Chronos correlates.

1

Place probes

Run a lightweight probe at each point you care about — venue, cloud production, transcode, CDN edge. It fingerprints frames as they pass.

2

Correlate frames

Chronos matches the same frame across probes — even after re-encode — and computes delay, drift and sync between every pair.

3

Watch it live

A real-time map of your whole path: per-hop and end-to-end latency, A/V sync, and alerts the moment a stage adds time.

Features

Built for live, by people who do live

ms

Point-to-point latency

The real delay between any two probes on the path, updated every cycle.

∿

Drift & clock trust

PTS-vs-wall-clock slope per probe — catch a drifting encoder before it desyncs.

A/V

Sync monitoring

Audio-to-video offset across the chain, with thresholds and alerting.

⌬

Multi-point correlation

Frame-fingerprint matching that survives re-encode, scaling and re-timestamping.

⚿

Tenant isolation

Your paths and data are scoped to you alone — secure by default.

⎙

History & export

Every measurement retained and queryable — prove an SLA, debug a past incident.

Who it's for

If it's live, latency is your problem

Teams that can't afford to find out about delay from an angry viewer.
