Ultra Low Delay and Resilient Multi-channel Video Encoder for Efficient Remote Construction

Abstract

Efficient remote operation of construction machines equipped with multiple video cameras requires smooth and real-time video transmission to simulate the experience of operating machinery in person. Due to the diverse network environments at construction sites, including satellite, Wi-Fi, and both public and private LTE/5G networks, an ultra-low delay video codec with adaptive bitrate control is crucial to maintaining low end-to-end latency in these environments. In this paper, the development of a multi-channel video encoder for the above requirements is described demonstrating the codec's performance across five types of wireless networks at a remote construction site.
