Control Signal Transmission

Stable transmission of control signals is critically important for remote control.
Soliton’s proprietary “RASCOW2 protocol” is equipped with redundancy and error correction functions, enabling uninterrupted and safe transmission of control signals superimposed on video and audio signals.


Short latency video transmission is essential for safe and smooth remote control.
The combination of our original RASCOW2 protocol and video compression technology has minimized the delay, which has been an issue until now.
Faster and more stable remote control is realized by using not only LTE but also next-generation communication technologies such as 5G and MEC.

Multi Link

Network Bonding

The multi-link function bundles multiple lines for stable transmission over a wide bandwidth.
High-definition video can be easily transmitted over a multilinked mobile line.
H.265 / HEVC compression codec reduces the amount of data transferred, enabling transmission over LTE and next-generation 5G / MEC.
Compared to the previous generation H.264, the image quality at the same bit rate is approximately twice as high.

Zao SDK Starter Kit

This starter kit includes all the hardware, software, and services necessary to start developing with Zao SDK.
The kit includes the NVIDIA Jetson Nano Developer’s Kit as well as six months of LTE connectivity and cloud services.
It allows rapid prototyping for the development of high-quality and redundant remote control systems.
