Resilient Streaming Protocol
Resi’s patented Resilient Streaming Protocol (RSP) keeps your live stream running — even when your internet doesn’t.
Trusted by thousands of organizations across faith, education, government, events, and more.
Unmatched Reliability
Streams stay live through network drops, bandwidth spikes, and unstable connections.Error-Free Delivery
Flawless audio and video from encoder to screen, with no buffering or pixelation.Instant Recovery
Connection drops? RSP stores the data locally and resumes without missing a moment.Focus on Your Message. RSP Handles the Rest.
Most streaming protocols were designed for ideal networks. RSP was designed for real ones — spotty venue Wi-Fi, rural satellite connections, gym networks flooded with smartphones. When packets are corrupted, RSP retransmits only the affected data. When bandwidth fluctuates, adaptive bitrate keeps the picture clean. When your connection drops entirely, RSP stores up to 10 minutes of video locally and resumes from the cloud once it’s restored — invisible to every viewer.
- Adaptive Bitrate: Maintains video quality under any network condition without viewer interruption.
- Selective Retransmission: Retransmits only corrupted data — not the entire stream — preserving quality without straining the network.
- Network Stability by Design: Handles unpredictable internet so your operators can focus on the event, not the infrastructure.
Works on Any Network. No IT Team Required.
RSP doesn’t require a dedicated broadcast crew or a perfectly configured network to perform. It operates across standard internet ports, which means it works even through strict firewalls. If your connection switches mid-stream — from wired to cellular, from one ISP route to another — RSP follows it automatically. No interruption. No manual intervention. Whether you’re running a multisite broadcast across campuses or streaming a one-camera service from a rural chapel, the setup is the same: connect, stream, trust it.
- Smart Routing: Automatically reroutes around bad ISP paths — like a GPS for your stream.
- Network Flexibility: Switch networks mid-stream without dropping the broadcast.
- Firewall-Friendly Architecture: Works across standard internet ports without special configurations.
CUSTOMER STORY
Live Streaming from Rural Alaska
Even in one of the most isolated corners of the world, Resi helps Alliance Christian Fellowship Church broadcast confidently every week.
Increased Viewership
Longer Watch Times
Fewer Streaming Complaints
Error-Proof Streaming
RSP ensures multi-bitrate video is generated from a flawless audio/video source — preventing data loss during transmission before it ever reaches a viewer.
Gapless Viewing Experience
When network loss occurs, the RSP cloud transcoder pauses and waits. Once the connection restores, it resumes from exactly where it left off. Viewers experience no gaps, no jumps, no missing moments.
Reliable Network Adaptability
RSP lets broadcasters stream from any network — switching connections mid-stream using standard internet ports — without worrying about bandwidth limits, connectivity gaps, or firewall restrictions. Resi’s purpose-built Mini, and server-grade encoders are all engineered specifically around RSP — hardware and protocol working as one.
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 10-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.

RSP is a patented live streaming technology developed by Resi that delivers complete, error-free audio and video even when network interruptions occur. It was designed specifically for mission-critical live events where stream quality and reliability aren’t negotiable.
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 10 minutes. That 10-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.
RSP uses selective retransmission and real-time data verification to confirm every packet reaches its destination intact. If the network drops entirely, RSP’s cloud transcoder pauses and waits. Once the connection restores, the encoder transmits the stored data and playback resumes — no gaps, no missing content.
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.
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.
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.
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.
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.
RSP was built specifically for events that can’t be replayed. Graduations, board meetings, wedding ceremonies, Sunday services — moments where a dropped stream carries real consequences. Its combination of 10-minute buffering, lossless failover, and viewer-side protection makes it the most reliable protocol available for high-stakes broadcasts.
