    QVidium – Pioneer in IP Video Transport and Error Correction

    July 1, 2020 @ 4:00 am - 5:00 am


    If you are transporting video over the internet, join us on Tues 30 Jun at 11:00 Pacific to learn the latest from QVidum, the inventors of ARQ.

    The Internet Video Problem:
    The Internet was never designed for Video

    “Best-Effort” Transport Only
    No Prioritization
    Routers Drop Packets to Alleve Congestion
    Dynamic Load Balancing Reorders Packets
    Traffic is either UDP or TCP

    UDP Transport is Real-Time, but Lossy
    No Inherent Packet Recovery
    No Guarantees on Packet Order
    TCP Uses Positive Acknowledgement Packet Recovery
    Not Real-time: Pauses for Unrecoverable Packets
    Max Bitrate Limited by Distance & Node Hops
    The Internet Video Solution: ARQ – Automatic Repeat Request

    Automatic Repeat reQuest
    Feedback Requests Resending Lost Packets
    Receiver Delay to Allow Time for Recovery
    Add Receiver Buffer to Create Delay
    More Resilience → Larger Buffer
    Lower Latency → Smaller Buffer
    Capable of 100% Recovery
    Capable of Full Recovery with Large Loss %
    Zero Overhead on a Clean (Lossless) Network
