QVidium – Pioneer in IP Video Transport and Error Correction [Webinar Recording]
Posted on Thursday, June 11, 2020
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
