Low latency delivery
Traditional HLS streaming puts viewers 10 to 30 seconds behind real events. That gap closes betting windows, enables spoilers, and breaks interactive formats. Norsk delivers sub-second latency to browsers and CDN-scale audiences — via WebRTC for direct browser delivery and MoQ for global distribution — from the same workflow that produces your standard outputs. No separate low-latency pipeline required.
How it works
Low latency is not a separate infrastructure decision. Norsk produces sub-second outputs alongside standard HLS and DASH from a single workflow — choosing the right protocol per output, not per pipeline.
Traditional broadcast-to-stream workflows stack delay at every appliance boundary. Each encode, transcode, package, and segment handoff adds seconds. HLS was designed for reliable scale, not speed — glass-to-glass latency of 10 to 30 seconds is typical. Low-latency HLS and DASH extensions reduce this to 2 to 5 seconds, which is still too slow for betting markets, interactive formats, and in-venue screens. Norsk eliminates the appliance stack by handling ingest, processing, and multi-protocol output in a single system. There are no handoff delays between separate tools. The latency budget starts at the camera and Norsk does not add to it unnecessarily before the media reaches the distribution protocol.
WebRTC delivers sub-second latency to any modern browser without requiring a custom app or plugin. Norsk outputs WHEP (WebRTC-HTTP Egress Protocol) streams directly — the same workflow that encodes your HLS and DASH simultaneously produces a WebRTC output on the same timeline. SRT and RTMP contribution sources come in, and the sub-second browser output goes out alongside standard distribution outputs. WebRTC is the right choice when latency is the priority and the audience is reachable via browser: live auctions, interactive broadcasts, call-in formats, in-venue control rooms, and any experience where the viewer needs to respond to what they see in real time.
WebRTC's architectural constraint is audience scale: peer connection models do not use CDN infrastructure natively, so large concurrent audiences require additional engineering. Media over QUIC (MoQ) resolves this. Built on QUIC — which combines TCP's ordered reliability with UDP's low-latency transport — MoQ works natively with CDN relay networks, turning existing infrastructure into a live streaming relay. Cloudflare's 330-city global network delivers MoQ streams in under a second to viewers anywhere. Norsk has supported MoQ since 2024, participated in the IETF working group through spec co-developer Mike English, and demonstrated end-to-end sub-second delivery with Cloudflare live at NAB 2026. MoQ is now the default protocol for Norsk Studio's internal Preview component.
Use cases
The operations that benefit most are those where the gap between what happens and what the viewer sees has a measurable commercial or product consequence.
A broadcaster covering live sport with active betting markets finds that the standard HLS delivery delay has a direct commercial consequence: viewers watching on the stream cannot place in-play bets on events they have not yet seen. Social media users watching at the venue or on competing sub-second streams spoil outcomes for the delayed audience. The delay is not a technical complaint — it is a product difference that moves viewers to lower-quality alternatives with better latency.
Norsk delivers a MoQ output to Cloudflare's global relay network alongside the standard HLS/DASH outputs from the same workflow. The MoQ audience receives the stream in under a second. Betting windows stay open. The experience on the primary stream matches what viewers at the venue see. No separate low-latency pipeline, no additional infrastructure cost.
Talk to us about your sports workflow →A live commerce or auction platform builds its format around viewer response to what the host is presenting. With 15 seconds of latency between the host's action and what the bidder sees, the interaction is broken: bids arrive after lots close, reactions are disconnected from the moment, and the live format stops feeling live. Standard streaming infrastructure was not built for this loop, and adding a separate WebRTC layer means a separate encoding and management system.
Norsk outputs WHEP directly to any modern browser from the same pipeline handling recording, production switching, and standard distribution. Sub-second latency for the interactive audience; standard outputs for recording and broadcast simultaneously. The interactive format works because the viewer and the host are in the same moment.
Talk to us about your interactive workflow →A stadium operator running large venue screens showing replays and live coverage finds that a 5-second delivery delay is visible when the crowd reacts to a goal before the screen shows it. The screens undercut rather than enhance the live experience. The contribution path from the pitch to the encoding system is local and fast — the latency is introduced in the streaming and distribution stack before it reaches the screens.
Norsk encodes from the venue contribution source and delivers via MoQ or WebRTC to venue screens with end-to-end latency low enough that the screen and the pitch are effectively simultaneous. The same Norsk workflow handles the venue output and the broadcast outputs — one system, right latency per output.

Norsk has supported MoQ since 2024 — one of the earliest production implementations. The NAB 2026 Cloudflare demonstration was end-to-end: Norsk Studio encoding, Cloudflare MoQ relay, sub-second delivery to the viewer.
Norsk Studio has dedicated MoQ input and output components for Cloudflare, with full support for spec version 16. MoQ is the default protocol for the Studio Preview component — every workflow previews at sub-second latency by default. Norsk participated in the IETF MoQ working group through spec co-developer Mike English, and was among the first vendors to move MoQ from experimental to integrated production feature.
MoQ turns CDN infrastructure into a live streaming relay — Cloudflare's existing network of 330 cities can deliver sub-second streams to viewers worldwide without purpose-built media infrastructure. The Norsk/Cloudflare integration makes this available as a standard output from any Norsk workflow. Dane Knecht, Cloudflare CTO: 'Every server can now deliver live video in under a second to viewers nearby. That's the kind of scale and performance that used to require purpose-built media infrastructure.'
Norsk outputs WHEP streams directly from any workflow. Any modern browser receives sub-second video without plugins, custom apps, or separate encoding infrastructure. The WHIP standard covers low-latency WebRTC contribution ingest. WHEP output and HLS/DASH output run simultaneously from the same Norsk pipeline — the latency choice is made per output, not per system.
Norsk Studio measures glass-to-glass latency end to end, surfacing the actual number in the dashboard. When protocols are compared, configurations adjusted, or network conditions change, the real latency is observable rather than estimated. Sub-second delivery is a claim — Norsk makes it a number.
A single Norsk workflow simultaneously produces HLS and DASH for broad distribution, WHEP for sub-second browser delivery, and MoQ for CDN-scale sub-second delivery. The latency trade-off is made per output, not per pipeline. Running a separate low-latency infrastructure alongside a standard streaming stack doubles operational complexity — Norsk avoids this entirely.
SRT (Secure Reliable Transport) preserves the low-latency budget at the contribution leg. For venue-to-cloud or field-to-studio workflows, SRT maintains sub-second ingest latency over unpredictable internet connections — bonded cellular, public Wi-Fi, or shared venue connectivity — without sacrificing reliability. The glass-to-glass budget is protected from the first hop.
