What is Zixi OnAir?

In the current climate where it is difficult to bring a large production staff with a great deal of equipment to a production site, content providers are looking for ways to capture and deliver live streams with less gear and smaller teams. Surprisingly, many are finding that key to delivering broadcast-quality streams from remote locations can be found in their pocket.

While live production has become more challenging during the pandemic, the appetite for streaming content has never been higher. With many brands and content providers looking for ways to connect with audiences sitting at home in front their screens, remote production has been key to satiating the demand for content.

Over the past year, mobile apps have become increasingly popular for live production needs for occasional use live events and productions. With a large install base and high-quality video capture built into mobile devices, mobile apps designed for streaming over IP networks provide a seamless way to quickly enable both experienced and novice production teams. Remote production techniques that rely on mobile applications for content capture and delivery allow content providers to produce content in a cost-effective manner and connect with their fan base at a time when attention is at an all-time high.

Zixi’s OnAir mobile app provides a mobile entry point to the Zixi Internet video transport architecture. The application allows users to stream live from an iOS or Android device (phone or tablet), while using the device's built-in camera to encapsulate the encoded video and audio and prepare them for transmission over standard Internet connections using Zixi’sUDP-based transmission protocol, RTMP, or RIST


The application works exclusively with a Zixi Broadcaster, which enables high quality streaming and format conversion to HLS, HDS, MPEG-DASH, MPEG-TS and RTMP,and RIST so the live video can be watched on any device, decoded on professional decoder or published to a CDN.There is also an option to send the stream using RTMP or RIST protocol. You can also add an additionalRTMP target while streaming to a Zixi Broadcaster with Zixi protocol.

Zixi’s Transport Stream architecture deploys monitoring, control, and intelligence along the entire transmission path. It is uniquely designed to deliver the quality and reliability that enables live contribution from any device to a cloud or on premise version of Zixi Broadcaster.

Zixi’s Software bonding capability (iOS only) delivers a high-quality stream even in degraded network conditions. There are two modes of operation: Live Streaming, which streams content to the broadcaster in real time.
