What the stitching solves.

Quality of experience first, then everything the delivery has to hold around it — and each claim a mechanism you can check, not a promise.

The system, live

Watch a switch happen.

A degrading CDN, a draining buffer — and the next segment already coming from a healthy source. The viewer never moves.

The viewer never moves CMCD — buffer, bitrate, live from the player vidNT brain scores every CDN, per viewer, continuously CDN A healthy CDN B healthy CDN C healthy segments flow from the CHOSEN source — the switch happens between one segment and the next
Serving from CDN A — buffer healthy.
Start here

Quality of experience is the first job.

Everything else — cost, capacity, migration — is optimisation on top of a stream that has to keep playing. So it goes first, and it is the one thing we measure per viewer rather than per region.

Quality of experience

Decisions made from the player's own signals.

Buffer level, delivered bitrate, object type, startup and stall events — CMCD from the actual session, measured while it plays. The brain scores every CDN per viewer and per network, continuously, and moves the source before the viewer feels anything.

Every claim on this page is a mechanism you can check on your own stream.

How the quality decision works The parameters we collect The analytics you get back

What we read, live

  • Buffer length and buffer starvation, per session
  • Delivered bitrate against the ladder you publish
  • Startup time and rebuffer events
  • Which CDN served each segment, and from cache or origin
  • Network and region the viewer is actually on

Then

What else the delivery has to hold.

Four more jobs, in the order they usually become urgent.

Keep playing

A CDN fails, the stream does not

Connected viewers get rescued, not just the next ones to arrive.

How the stream survives →
Spend less for the same quality

Cost-aware routing

Contract rates, caps and commitments enter the decision — under a quality floor, never above it.

How cost enters the decision →
Survive the peak

Concurrency and capacity

Kickoff spikes, one-night events and always-on channels — the traffic shapes that break single-CDN delivery.

Built for match night →
Change without risk

Migration and control

Import what you run today, watch it in shadow, move traffic when the numbers agree with you.

Move what you run →
Where it is hardest

The deliveries that punish a mistake.

Same brain, different failure cost.

Live sports

Every viewer arrives in the same sixty seconds, and nobody forgives a freeze at the goal.

Match night →

One-off live events

One night, no second chance, no time to discover a CDN problem the slow way.

Event delivery →

Medical video

Video that must not drop, with session data that must not leave your account.

Critical video →
Technology

What the delivery is built on.

The mechanisms under all of the above — and the patent family that protects them.

The brain

AI routing, on the serving path

Scores every CDN per viewer and network, continuously, and acts inside the delivery loop — never a dashboard you have to read.

Inside the brain →
The standards

CMCD, CMSD, Content Steering, SCTE-35

We speak what your player and your CDNs already speak, so the signals are native and the switch is standard.

The signals we use →
The protection

Patent-protected technology

Server-mediated CDN selection, mid-stream switching and client-cooperative delivery are covered by the Vimmi patent family — the mechanism itself, not a configuration of someone else’s.
