A GoP based FEC technique for packet based video streaming

In this paper, we propose an efficient forward error correction (FEC) technique for video transmission in a lossy network. Here, the FEC is applied on source packets at group of pictures level assuming an MPEG-like compression scheme. We also derive analytically an estimate of the playable frame rate for the proposed technique. It is shown, by both analysis and simulation, that the proposed FEC technique provides a better playable frame rate than the classical frame-level FEC techniques.
