What is LRT™?

What is LRT™?

LiveU Reliable Transport, or LRT™, is the video and audio delivery protocol developed over the last decade by LiveU, the inventor and patent holder of cellular bonding. The LRT™ protocol supports low latency, high resiliency video and audio transmission and was built from the ground up to accommodate the special properties of 4G/5G cellular as well as more traditional wireless and wired networks. In particular, LRT™ is optimized to support the bonding of multiple IP connections.

Optimized for bonded IP transmission, LRT™ ensures top reliability and bandwidth consistency across the most challenging cellular networks. While other resiliency protocols use only one or two techniques, LRT™ applies multiple resiliency techniques simultaneously such as Packet Ordering, Acknowledge & Resend, Dynamic Forward Error Corrections and Adaptive Bitrate Encoding.
