Tambur - Efficient Loss Recovery for Videoconferencing via Streaming Codes

Explore an innovative approach to improving videoconferencing quality through efficient packet loss recovery in this 20-minute conference talk from NSDI '23. Dive into the development of Tambur, a streaming-codes-based system that outperforms conventional forward error correction (FEC) methods in handling burst losses. Learn how Tambur reduces decoding failures for video frames by 26% and bandwidth usage for redundancy by 35% compared to baseline approaches. Discover the implementation details and integration process with a videoconferencing application, and examine the end-to-end quality of experience (QoE) improvements, including a 26% reduction in freeze frequency and 29% decrease in cumulative freeze duration. Gain insights into the potential of streaming codes to revolutionize real-time communication technologies and enhance long-distance videoconferencing experiences.
