What Makes Zixi’s Low Latency Delivery Unique

With Zixi’s ultra-low latency video delivery, content providers can deliver live video over mixed networks while continuously optimizing for the lowest latency obtainable.

Zixi is the only solution in the market that actively manages latency with congestion and content aware optimizations that continuously drive latency out of the end-to-end distribution. Ultra-low latency live delivery is maintained and synchronized across devices, network locations and conditions so that content providers can deliver video in realtime to the end user with confidence.

Demystifying Video Streaming Latency: A Comprehensive Guide

Read the guide

Understanding and managing latency is paramount in delivering video content efficiently, especially in time-sensitive scenarios like sports broadcasting. This guide focuses on the contribution side of a video pipeline, highlighting key terms and shedding light on the Zixi protocol’s approach to latency.

Latency Optimized Live Delivery

Most systems require operators to specify a target latency which may not always be feasible as network congestion and performance changes. Zixi’s Software-Defined Video Platform is the only solution in the market that supports a 3-way tradeoff between latency, bitrate and resiliency. Zixi dynamically manages these dimensions, continuously optimizing to reliably deliver broadcast-quality live video at the lowest possible latency.

Zixi Advantages

Lowest Latency Currently in Production Use

The Zixi protocol provides the lowest latency in the industry for delivering broadcast-quality compressed video. Ultra-low worldwide transport latencies are practical and fully supported by the Zixi Software-Defined Video Platform.

Sub-second worldwide transport latencies are practical and fully supported by the Zixi Software-Defined Video Platform while preserving error free distribution over any network.

Network-Aware, Adaptive Bitrate Technology

The Zixi protocol is congestion and network aware and seamlessly adjusts to varying network conditions and employs patented, dynamic Forward Error Correction techniques for error-free video transport over 5G. Zixi’s unique ability to adapt the video quality to the available bandwidth makes it easy to maintain stream continuity for the optimal Quality of Experience.

Low Latency Transcoding and HTTP Stream Packaging

Zixi transcoding and HLS packaging supports CMAF and the community recommended chunked-based-encoding-and-transfer-approach supported by CDNs and video players. Using this approach, end-to-end live OTT streaming over HTTP networks with ultra-low latency is achievable.

Unmatched Resiliency with 99.999% Reliability

Zixi’s protocol uses a combination of adaptive FEC, ARQ, network bonding, congestion avoidance and hitless failover to algorithmically reconstruct data down the supply chain in potentially less than a round-trip. Zixi ultra-low latency delivery is backed up with a unique, patented hitless failover technique that creates one coherent stream out of multiple stream fragments with a DNA sequence alignment algorithm.

Unmatched Delivery Performance

Zixi’s protocol uses a combination of adaptive FEC, ARQ, network bonding, congestion avoidance and hitless failover to algorithmically reconstruct data down the supply chain in potentially less than a round-trip. Zixi ultra-low latency delivery is backed up with a unique, patented hitless failover technique that creates one coherent stream out of multiple stream fragments with a DNA sequence alignment algorithm.

Three-second latency setting with Zixi is very resilient to and from any location globally 90%+ percent of the time depending on architecture and workflow. Zixi latency can be adjusted to provide additional protection at problematic edge-point locations with extreme packet errors percentage, without interruption of the live stream.

Ultra-Low Latency on 5G Networks

Exciting new workflows are leveraging the performance of 5G networks and carrier MEC environments to unlock the lowest possible latency in live video production and distribution. While most consider Direct to Consumer to be the main use case for 5G distribution, there are a range of B2B use cases out there already being leveraged by content creators including tetherless contribution as well as widespread distribution.
