Delivering content in the highest quality is paramount for broadcasters and content creators alike. That’s where LRT comes in.  


LiveU’s unique Reliable Transport protocol (LRT™) is at the heart of LiveU products to deliver optimized video performance. LRT™ enables reliable, low delay live video streaming over non-guaranteed IP networks and ensures reliable transport over the most unreliable of networks, including cellular networks - allowing you to acquire exciting live content in even the most remote locations.



Packet Numbering

Packet Ordering

LRT uses numbered packets so that the packets can be re-ordered when they arrive out of order. Packet Ordering is an absolute requirement with connection bonding, where data usually arrives in a different order than intended.


Forward Error Correction 01

Dynamic Forward Error Correction

Forward Error Correction (FEC) adds some overhead to the stream to recover lost data faster.  LRT automatically varies the FEC parameters based on monitored network conditions.



Acknowledge and Resend

LRT can acknowledge large groups of packets if they all arrived. If some did not arrive, it can inform the streaming engine to resend needed data. By acknowledging large groups of packets at a time, LRT uses less overhead and latency. Unlike UDP, LRT gives complete feedback loop so the user knows that the data is arriving correctly.



Adaptive Bit Rate Encoding

As the bandwidth condition changes, LRT automatically recognizes this and informs the video encoder to allow it to adapt the bit rate of video it is delivering and keep the best possible stream within the available bandwidth at any given moment.
