Mesh-Pull-Based P2P Video Streaming System Using Fountain Codes
Hyung Rai Oh, Hwangjun Song · 2011
In this work, we propose a simple but effective mesh-pull-based P2P video streaming system using Fountain codes with variable symbol sizes for video-on-demand services. The goal of the proposed system is to provide a stable video streaming service of high quality with a low computational complexity and short initial latency. Fountain codes are adopted in the proposed system to simplify the handshaking procedure which causes a large initial latency, and to support a robust video streaming service. The proposed system works by using feedback information to reduce unnecessary encoded symbol generation. In addition, the Fountain code symbol size is continuously adjusted to minimize additional computational overhead required for Fountain encoding/decoding.
