The Lowest Latency Live Video Broadcasting Currently in Production Use

The Zixi protocol provides the lowest latency in the industry for delivering broadcast-quality compressed video. Managing ultra-low worldwide transport latencies is practical and fully supported in Zixi Broadcaster, delivering error-free video globally with less than 300ms transport latency and 100% packet recovery.

In a communication system there is a 3-way tradeoff between latency, bitrate and resiliency. Zixi Broadcaster continuously optimizes delivery, always driving latency down while preserving pristine broadcast-quality delivery.

Carrier-Grade Resilience & Multi-Tiered Layered Security

Zixi Broadcaster extends industry standards with market leading solutions for stream availability and security.


Live video broadcasting is sensitive to interruptions. Adaptive FEC, ARQ, network bonding, congestion avoidance and hitless failover algorithmically reconstruct data down the supply chain in potentially less than a round-trip, enabling >99.999% stream availability without negatively impacting latency and quality.

  • Bonded Delivery: Combines disparate topologies including 5G, LTE, Leased Lines and Unmanaged Internet, dynamically adjusting for fluctuating bandwidth, network congestion, packet loss and latency differences
  • Sequenced Hitless Failover: An improvement on SMPTE 2022-7, applies Zixi optimized alignment algorithms to re-create a single coherent uninterrupted stream out of multiple stream fragments
  • Route Orchestration: Distribute over geographically diverse signal paths, across regions and in discreet infrastructure locations
  • Resilient Architecture: Provision clustered and load balanced Zixi Broadcasters for continuous delivery applications


When managing live video broadcasting workflows, content and connection security is critically important. Best-in-class security protocols and the most sophisticated content protection strategies are available and easily implemented in Zixi Broadcaster, including the ability to encrypt content streams and secure video routes with DTLS. DTLS is a communications protocol that is based on TLS (Transport Layer Security), the same robust technology used for securing most popular applications such as HTTPS. This protocol permits streaming video systems to exchange data with other appropriate systems without allowing eavesdropping, tampering, or message forgery. DTLS enables the Zixi Broadcaster to provide best-in-class security for content transported over UDP.

Included with every Zixi Broadcaster deployment are configurable layered security options including:

  • Content Encryption: Secure content with End-to-end strong AES-256 content encryption
  • Session Security: Manage Access with Session Establishment Whitelisting & Password Protection
  • Connection Validation: Confidently Delivery with Zixi Exclusive DTLS Secure Certificate Validation & Strong Cipher Protection
  • Protected Multicasts: Zixi Protected Multicast validates and secures client multicast subscriptions
