LiveU Reliable Transport (LRT™) brings together the best video delivery techniques into one integrated protocol that is tightly integrated with the Solo encoder. Adaptive bitrate encoding, dynamic Forward Error Correction (FEC) and packet ordering are key components of LRT, supporting the rock-solid video streams LiveU is known for.
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.
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.
