Live from the operating theatre

Broadcasting surgery, the way it should be.

Built by a surgeon, for surgeons. TheatreKit connects live operating theatres to remote mentors, trainees and classrooms in real time — telementoring, proctoring and teaching with two-way audio, multi-theatre switching and built-in recording. All on low-cost, off-the-shelf hardware.

Everything a live theatre link needs, out of the box

Built on modern WebRTC, TheatreKit delivers video in under 100 milliseconds from camera to audience — not the several-second lag of traditional streaming platforms. It's a complete broadcasting system, not just a video call.

Under 100 ms latency

Real-time WebRTC streaming means the audience sees what the surgeon sees, as it happens. Questions and answers flow naturally — no awkward delays.

Multi-theatre switching

Run several theatres at once and switch the live feed from a single operator dashboard — or show all theatres side by side in a multiscreen view.

Two-way audio

The audience or remote expert can speak directly into the theatre, and the theatre talks back — with mix-minus audio so nobody hears an echo.

Any screen, anywhere

In-theatre monitors, conference displays, and remote guests in a normal web browser — no apps to install, no plugins, no specialist viewing kit.

True 3D, remotely

Robotic consoles see in stereoscopic 3D — and TheatreKit transmits it. Remote viewers wearing 3D glasses such as the XReal One or Viture Luma Pro get the same depth perception as the operating surgeon.

1080p: the sweet spot

4K needs four times the bandwidth for detail that's lost on projector screens and remote links — and most surgical stacks output 1080p natively. TheatreKit spends that bandwidth on a rock-steady, low-latency 60 fps picture that never buffers.

Private & secure

Self-hosted and encrypted end to end over the wire. Your footage stays on your own infrastructure — nothing is routed through third-party clouds.

Open & extensible

Built on open standards (WebRTC, OBS, LiveKit). Add cameras, theatres, overlays and picture-in-picture composites as your programme grows.

Built for surgical education

TheatreKit was created inside a working surgical unit to make live operating accessible to more learners, more often — without disrupting the theatre team.

Telementoring & proctoring

An expert mentor anywhere in the world joins the theatre from a browser — watching the operative view live and talking to the team in real time. Ideal for introducing new techniques and supporting surgeons through their early independent cases, without anyone leaving their own hospital.

Supervision of junior surgeons

A consultant can oversee a trainee's case from the next theatre, the office or home — stepping in with guidance the moment it's needed. More supervised operating for trainees, more flexibility for supervisors, better use of every list.

Teaching at scale

Medical students and theatre staff watch live cases from a seminar room instead of crowding the operating theatre. Big scope for education: one operation can teach a whole cohort — and the recording teaches the next.

Live surgery conferences

Stream multiple operating theatres into a conference auditorium with an operator switching between cases. Delegates watch in full HD and put their questions straight to the operating surgeon — a genuine live-surgery masterclass, without busing an audience into theatre.

Record. Review. Publish.

Every live case can become a lasting teaching asset. TheatreKit captures the full session — video and theatre audio — ready to revisit and share.

Record

Capture every theatre's feed automatically, with synchronised audio from the room and remote participants. No extra recording crew, no camcorders — it's built into the pipeline.

Review

Replay cases for debriefs, morbidity & mortality meetings, and structured feedback. Trainees can study their own operating; teams can analyse technique step by step.

Publish

Curate the best cases into an indexed video library for your department, training programme or society — turning one afternoon of operating into a permanent educational resource.

Serious broadcasting without the broadcast budget

Traditional theatre AV integrations cost tens of thousands per room. TheatreKit runs on compact, affordable, off-the-shelf hardware — installed without rewiring the theatre.

  • Palm-sized encoder box per theatre with hardware H.265 video encoding
  • One small server runs the whole system — switching, routing and recording
  • Works with existing laparoscopic stacks, microscopes and room cameras over HDMI or SDI
  • Standard hospital network — no dedicated AV cabling or satellite trucks
  • Scales a theatre at a time: add a box, add a theatre

Modular by design

Every part of TheatreKit — encoder boxes, cameras, server, displays — is an independent module speaking open standards. Upgrades are drop-in: a sharper camera, a more capable encoder box or a bigger server slots straight in, one piece at a time, without touching the rest. No rip-and-replace, no redesign, no five-figure AV re-integration — the system grows with you.

System agnostic — if it has an HDMI or SDI output, TheatreKit can broadcast it

Secure by architecture, open by standard

Patient footage demands more than a password. TheatreKit is built as a closed system on open standards — private infrastructure end to end, with nothing proprietary on the viewing side.

Closed private network

Theatres, servers and conference venues are linked over an encrypted site-to-site VPN. Media flows across your own closed network — never through a public streaming service or third-party cloud.

Encrypted end to end

Every stream is encrypted in transit with the same DTLS-SRTP security model that protects telemedicine and banking-grade WebRTC — encryption is mandatory in the protocol, not an optional extra.

Token-based access

Viewers and remote guests join with scoped, short-lived access tokens issued per role — a guest can only ever see and hear what their role allows. External access is limited to guest pages only.

Self-hosted, your data

The whole platform — switching, routing, recordings and the video library — runs on hardware you control, inside your governance boundary. No vendor lock-in, no data leaving your estate.

Web standards compliant

Built entirely on W3C and IETF standards: WebRTC for transport, H.264/H.265 and Opus for media, plain HTML5 for every screen. No proprietary protocols, no black boxes.

Zero-install viewing

Because it's standards-based, any modern browser is a fully fledged viewing station — Chrome, Safari, Edge or Firefox on any device. Nothing to install, nothing to maintain on the viewer's side.
