What Is SRT Streaming?
What does SRT stand for? SRT — Secure Reliable Transport — is an open-source video transport protocol designed to deliver high-quality, low-latency SRT video streams over the internet. The SRT protocol ensures stable streaming even across unpredictable networks by using advanced error correction, packet recovery, and AES-128/256 encryption.
Where traditional satellite transmission requires expensive uplinks and dedicated bandwidth, the SRT protocol runs on standard IP-based networks — fibre, broadband, or even bonded 5G — making SRT delivery both cost-effective and flexible. SRT supports AES-128 and AES-256 encryption natively, securing video streams end-to-end without additional hardware.
Why the Industry is Moving from Satellite to SRT
Broadcasters, esports organisers, and event producers are rapidly adopting the SRT protocol for SRT video delivery because it offers clear advantages over satellite transmission:
- Cost Savings – No need for costly satellite transponders or uplink facilities.
- Flexibility – Works from OB trucks, studios, hotels, or even remote field reporters using bonded cellular.
- Low Latency – Typical SRT delay is 200–400ms, compared to ~500ms with satellite. For applications where timing is critical, see our guide to low-latency streaming.
- Scalability – One SRT contribution feed can be redistributed to multiple platforms and rights holders via a CDN.
- Security – End-to-end encryption protects content during contribution and distribution.
Our Experience: SRT at the Esports World Cup
At the Esports World Cup in Riyadh, Creative Broadcast Agency was trusted with delivering live esports action to millions of fans worldwide.
- Multi-Arena Connectivity – Five esports arenas were connected back to the Master Control Room (MCR) over SRT.
- Remote Contribution – Our 5G bonding units carried roaming reporter feeds directly into the OB workflow.
- Global Rights Distribution – Using SRT, we delivered live clean feeds to international broadcasters and TV channels that purchased rights, while also streaming to YouTube and other digital platforms.
- Reliability Under Pressure – With $27 million in prize money and a global audience, SRT provided the secure, low-latency backbone needed for flawless transmission.
This proved that SRT can reliably replace satellite for global sports and esports events, offering the same quality with greater flexibility and lower costs.
Smarter Multi-Destination Streaming with SRT
One of the most powerful ways we use SRT is for multi-platform distribution.
In many venues — such as hotels or conference centres — internet bandwidth is limited. Streaming separately to three platforms (e.g., YouTube, Facebook, LinkedIn) from the venue risks network saturation and failure.
Instead, we send one SRT video stream to our MCR via SRT delivery. From there, we:
- Redistribute to multiple streaming destinations.
- Maintain consistent bitrates and quality.
- Insert graphics, branding, or closed captions centrally.
- Switch quickly if a platform fails.
This workflow ensures very low latency distribution while minimising strain on local venue networks. It’s more reliable, professional, and scalable — making it the preferred model for high-profile corporate events, esports, and NGO webcasts.

The Future of Broadcasting with SRT
From global esports tournaments to corporate conferences and NGO live streams, the SRT protocol is now the backbone of modern live SRT video distribution and broadcasting. It offers:
- Secure, low-latency video transport over public internet.
- Efficient global distribution from a centralised hub via CDN.
- Cost-effective replacement for satellite links.
At Creative Broadcast Agency, we’ve proven time and again that SRT streaming delivers broadcast-quality reliability for live event streaming clients including Google, the UN, and international sports organisers. Whether from a hotel in Dubai, a global esports arena, or a UN assembly hall, the secure reliable transport protocol enables us to stream smarter, faster, and more securely.
Frequently Asked Questions
What does SRT stand for in streaming? SRT stands for Secure Reliable Transport. It is an open-source video transport protocol created by Haivision and now maintained by the SRT Alliance. The SRT protocol is designed to deliver low-latency, encrypted video streams over unpredictable IP networks.
What is the difference between SRT and RTMP? RTMP (Real-Time Messaging Protocol) was the standard for live streaming contribution for over a decade, but it lacks encryption, has limited error correction, and does not handle network congestion well. The SRT protocol adds AES encryption, forward error correction, and adaptive bitrate — making it more secure, reliable, and better suited to contribution over the public internet.
Can SRT replace satellite for live broadcasting? Yes. SRT is now widely used as a direct replacement for satellite uplinks in sports, esports, corporate, and news broadcasting. At the Esports World Cup, Creative Broadcast Agency used SRT to deliver live feeds to international broadcasters — proving it can match satellite reliability at a fraction of the cost.
What equipment do I need for SRT streaming? You need an SRT-capable encoder (such as Haivision Makito X4, Evertz XPS, or Kiloview P3) at the source, and an SRT decoder at the receiving end. For mobile contribution, bonded 5G routers with SRT support (LiveU, Teltonika) provide connectivity from locations without fixed internet.
How does SRT compare to SMPTE 2110? They serve different purposes. SMPTE 2110 is a facility-level standard for transporting uncompressed video, audio, and data over managed IP networks within a broadcast plant. SRT is a compressed transport protocol for sending encoded video over unmanaged networks (the public internet). In practice, a production facility might use SMPTE 2110 internally and SRT for outbound contribution and distribution.
Does Creative Broadcast Agency provide SRT streaming services? Yes. We deploy SRT for live event streaming, contribution feeds, multi-platform distribution, and remote production across the UAE and GCC. Contact us for a production quote.
