Video that follows attention
Adaptive Stream picks a useful video layer for each viewport. Dynacast pauses layers nobody is watching, leaving room for the conversation.

- Your application
Make the call part of your application. Synton handles media forwarding, changing connections, and recording while you shape the experience.
01 / The media engine
Keep the experience.
Hand off the hard parts.
Audio stays in the foreground
Opus, discontinuous transmission, and deliberate jitter-buffer pacing keep speech intelligible as room activity changes.
A boundary around every room
Mint a short-lived ticket on your server. Limit who can join, publish, or subscribe before a client reaches signaling.
Recording on its own path
Provision workspace-specific recording egress. Capture an authorized session without tying capture work to participant devices.
02 / How it works
From your server
to a shared room.
Issue the invitation.
Your backend requests a room ticket with a participant identity and explicit media permissions.
Join the assigned region.
The browser SDK opens signaling, negotiates media, and publishes the tracks your interface enables.
Let the room respond.
Subscriptions follow visible participants. Video layers adjust as available bandwidth changes.
Browser SDK / room lifecycle
const room = new LivekitClient.Room({
adaptiveStream: true,
dynacast: true
});
await room.connect(regionalUrl, roomTicket);
await room.localParticipant.enableCameraAndMicrophone();03 / In your application
Different products.
The same room primitives.
Engineering, without the meeting detour
Keep a 20-person standup inside the tools the team already uses. VP9 layers at 180p, 360p, and 720p let a small tile cost less than the active speaker.
Expert sessions on difficult networks
Let a specialist join from an enterprise workstation. Regional TURN fallback gives restrictive corporate networks a supported route into the room.
A live session with a longer life
Bring a presenter into an interactive session, then send authorized recording output to the workspace’s configured destination.
04 / Before you build
A few useful answers.
Will a crowded room consume every subscriber’s bandwidth?
Adaptive Stream requests layers that fit each visible tile. Dynacast stops publishing unused layers. Your interface can also limit which tracks a participant subscribes to.
What if a corporate firewall blocks direct media?
The client negotiates an available regional TURN relay. Network conditions still set the latency floor; validate the experience on the networks your users rely on.
Why issue a ticket before connecting?
Your backend controls room membership and media permissions. A ticket carries those grants into signaling without exposing the workspace credential to a browser.
Can we create a workspace immediately?
Provisioning begins with a capacity and security review. The Synton team agrees room concurrency, deployment region, and recording needs before enabling a dedicated workspace.
Bring your room requirements.
We will work through concurrency, region, and media policy.
