Abstract

To achieve optimal performance, streaming video requires a TCP-Friendly data rate as well as resistance to lost packets. This project implements an adaptive forward error correction (AFEC) system with temporal scaling for streaming MPEG, which repairs video frames in the event of packet loss. Data is transferred via a TCP-Friendly UDP flow which responds to network conditions to reduce congestion and optimize performance. Adaptive FEC is comparable in performance to fixed FEC, and in some test cases, outperforms it.
