The Challenge of Live Video Transport

Delivering high-quality live video over the public internet presents unique technical challenges that traditional protocols were never designed to handle.

Network Unpredictability

  • Packet loss disrupts video quality and continuity
  • Jitter causes inconsistent delivery timing
  • Bandwidth fluctuations impact stream stability
Public internet

Public Internet Limitations

  • No guaranteed quality of service (QoS)
  • Variable latency across different paths
  • Security vulnerabilities in transmission

Why SRT Is the Standard for Secure Live Video

Open Source & Community Governance

SRT is built on principles of openness, collaboration, and vendor neutrality, ensuring long-term sustainability and innovation.

Open source

Open Source License

  • Released under the Mozilla Public License 2.0 (MPL-2.0), SRT is free to use, modify, and distribute.
  • The permissive license enables commercial adoption while ensuring the protocol remains open and accessible.

Active Development

  • The SRT protocol and reference implementation are maintained on GitHub with contributions from the global community.
  • Regular updates, bug fixes, and feature enhancements ensure SRT evolves with industry needs.
Collaboration

Collaborative Community

  • A diverse ecosystem of developers, vendors, and broadcasters contribute to SRT’s development and adoption.
  • Open governance ensures no single entity controls the protocol’s direction or implementation.
Vendor neutral

Vendor Neutral Stewardship

  • While originally developed by Haivision, SRT is stewarded by the SRT Alliance to prevent vendor lock-in.
  • The Alliance ensures interoperability and standards compliance across all implementations.

Trusted Worldwide

More than 700 broadcasters, cloud platforms, device manufacturers, and streaming providers rely on SRT for secure, low-latency video transport.
