About The Zao SDK for Jetson

Reliable and Secure Live Streaming for Teleoperation

Soliton Systems Zao SDK for Jetson, is a cutting live streaming OEM product for teleoperations, teledriving, remote robotic control, and BVLOS drone manufacturers. It utilizes RASCOW2 protocol for near real-time streaming with ultra-low latency and extreme reliability, using patented bonding technology to combine multiple cellular networks for seamless, high-speed connections, enabling remote operators to safely control devices in real-time.

Zao SDK Key Features

Low Latency

Ultra Low Latency

RASCOW2 (Real-time Auto Speed Control based On Waterway-model) is Soliton’s second generation codec for video optimization. It ensures fast and highly reliable adaptive encoding that is optimized on available network bandwidth, even in the most challenging of situations.

Remote Control


Zao SDK enables remote control of a car, robot, drone or machinery in almost real-time from a remote location. Traditional encoders have a delay greater than 0,5 second that is too long for safe control. Zao SDK can remotely control machinery, viewing a live video stream and remote operation in almost real time.

Stable and High Speed

Multilink Bonding

Mobile networks from different cellular telecom carriers can be bonded into one single network connection significantly increasing bandwidth and resilience. It remove the reliance on a single network operator and with RASCOW2 can deliver superior live streaming up to 4K video formats.

High Video Compression


Zao SDK is a highly efficient HEVC/H.265 hardware encoder and compared to a traditional H.264 codec, transmits video with almost half the bandwidth. Soliton's H.265 process is highly efficient for encoding and decoding that is a major element in the measure of super low latency video streaming.

Ultra Low Latency, 4K UHD and
5G Support

Cutting edge innovation with UHD resolution, the Zao SDK has full support of 4K live streaming with LTE and 5G supported networks, as well as satellite, Wi-fi and LAN. Supporting Ultra Low latency with streaming delays below 100ms, the Zao SDK for Jetson can be customized to support an array of different cameras including USB, GMSL, IP camera, and MIPI.

Receiver and controller software is via Zao Cloud with fully customizable Zao Cloud View browser clients. The receiving end   can be installed on-prem or in the cloud including Multi-access edge computing, (MEC) cloud environments.

The network connection supports ultra low delay on the return control signal, via serial or LAN tunneling  from the receiving location back to the remote device for remote control.
