Protection

Protection that's in a different league

When your connection drops, RSP stores video locally and resumes from the cloud — seamlessly. The moment your audience is watching doesn't pause.

Purpose-built

Purpose-built, not repackaged

RSP isn't open-source SRT wrapped in a new interface. It's patented Resi technology, engineered from the ground up for the streams that cannot fail.

End-to-end

Resilience all the way to the screen

Most protocols protect the broadcast uplink. RSP goes further — protecting the viewer's experience end to end, including flawless recordings in the cloud and on YouTube.

Comparison

How RSP Compares to Other Streaming Protocols

The streaming protocol you choose determines what happens when things go wrong — and things always go wrong eventually. RSP operates in a different category from RTMP, SRT, and Boxcast Flow. Here’s what that looks like in practice.

SRT improved on RTMP — but its 8-second buffer window still leaves streams vulnerable to the kind of real-world network disruptions that happen at convention centers, school gyms, and rural venues. RSP’s 30-minute buffer window isn’t a minor improvement. It’s a fundamentally different level of protection. And RSP is the only protocol that protects both sides of the stream — not just the broadcast uplink, but the viewer’s experience all the way to the screen.

Frequently asked questions

Why does a longer buffer time matter for live streaming?
Buffer time is your safety net. RTMP has zero buffer — any network disruption kills the stream instantly. SRT offers 8 seconds. RSP offers up to 30 minutes. That 30-minute window is the difference between a dropped connection that nobody notices and a stream that falls apart during the sermon, the vows, or the keynote.
How does RSP work?
RSP offers the most resilient streaming experience by focusing on four key factors: Selective retransmission — when packets are lost or corrupted in transit, RSP identifies and retransmits only the affected data, preserving quality without overwhelming the network. Cloud buffer up to 30 minutes — if your connection drops entirely, RSP stores the stream locally and resumes from the cloud once it restores; viewers see nothing. Adaptive bitrate — as bandwidth fluctuates, RSP adjusts automatically, maintaining visual quality without buffering, pixelation, or a drop in resolution. Smart routing — RSP detects unstable ISP routes and reroutes around them in real time, like a GPS for your stream, finding the clearest path to your audience without any manual intervention.
How is RSP different from RTMP?
RTMP was built in the early 2000s for a different internet. It has no error correction and zero buffer tolerance — any disruption results in a failed stream. RSP was engineered from the ground up for the networks organizations actually work with: inconsistent venues, shared Wi-Fi, rural connections. When something goes wrong, RSP recovers automatically. RTMP doesn’t.
What happens when the network drops mid-stream?
RSP encodes and stores audio/video data locally at the encoder. Once the connection restores, the encoder transmits the stored data to the RSP cloud transcoder, which resumes processing exactly where it left off. Viewers don’t experience a gap, and the cloud recording stays flawless.
Can RSP work through firewalls or on restricted networks?
Yes. RSP is built to operate across standard internet ports, which makes it compatible with firewalls and restricted network environments that block other protocols. It doesn’t require special network configurations or IT workarounds to function reliably.
How does RSP handle on-demand content?
Because RSP produces a flawless source recording — even during network disruptions — that content can be immediately uploaded to Resi On Demand after the live stream ends. No re-encoding, no cleanup, no post-production hours spent fixing a corrupted file.
What do I need to use RSP?
RSP is available through Resi’s purpose-built hardware: the Mini encoder, and Resi’s server-grade hardware. It’s also available via ProPresenter Stream software. RSP is a Resi-native protocol — the hardware and software are engineered together so the protocol performs exactly as designed.
