Video Delivery


Zixi's technology harmonizes congestion-aware and network adaptive forward error correction, time-controlled error recovery, bonding multiple transmission paths and bitrate adaptation to make the internet usable for professional video.

Whether your business model is built on ad revenue or subscriptions, Zixi’s superior video delivery service provides the technical flexibility to meet the demands of today's media consumer.

Meeting the ever-changing needs of today's audiences is why Zixi has long advocated for adopting open standards. We recently announced commercial availability of Reliable Internet Stream Transport (RIST). Press release available here.  RIST is in development by the Video Services Forum, an international association comprised of service providers, users and manufacturers dedicated to interoperability, quality metrics, and education.

Live Linear/Event Streaming

Zixi addresses the core delivery challenges of live streaming. Our technology enables high source stream quality, handles network congestion and interruptions gracefully, supports multiple devices and requires minimal time for processing and caching.

Adaptive Bitrate

Adaptive Bitrate streaming requires technology that can detect a client's QoS in real time and deliver source content at the most appropriate bitrate over HTTP. Zixi’s streaming protocol is itself adaptive, allowing low latency adaptive streaming to players or decoders that would otherwise be incapable of bitrate adaptation, such as IRDs and transcoders.


Hitless Failover

Using smart innovation and sophisticated algorithms to reconstruct sequences of IP packets, the Zixi Platform delivers robust hitless failover that surpasses any other solution. Our continual R&D efforts demonstrate our ongoing commitment to improving the highest levels of broadcast quality over IP networks.

Forward Error Correction

Zixi combines Forward Error Correction, re-transmission and congestion avoidance in an optimized and efficient way.


The Zixi Platform delivers broadcast quality live video over IP with best-in-class multi-layered security, including restricted access control and AES encryption. For UDP video delivery protocols, we also provide DTLS (datagram transport layer security) that is exclusive to our Platform and makes content delivered via Zixi the most protected UDP transport in the market today.

Why is broadcast quality live video over the internet so hard?

Look at all that can go wrong.

Open Standards Solution Options


  • The emerging Reliable Internet Stream Transport (RIST) initiative is being developed by the Video Services Forum (VSF), an international association dedicated to interoperability, quality metrics, and industry education
  • Zixi is working with the VSF as well as other global service providers, users and manufacturers to develop RIST, Reliable Internet Stream Transport
  • Zixi has long been a major contributor to the history of open standards and RIST Specification, including MPEG-DASH, MMT, SMPTE 2022-2 and 2022-7 (RTP)
  • Zixi guarantees compatibility with current and future RIST advancements

“We are engaged in many interoperability tests with the Video Services Forum’s working group,” says Uri Avni, founder and CTO, Zixi “The results are encouraging, and we will continue to support the initiative as it evolves.”

Zixi RIST Standard Support

  • Tested interoperability with all other vendors
  • Continuous Zixi support guaranteeing compatibility and future RIST advancements, including bonding and pull mode
  • DTLS encryption support pending
  • Network bonding (when approved)
