Fine Grain Adaptive FEC (FGA-FEC) Over Wireless Networks

In this paper, we extend our proposed FGA-FEC coding scheme, a generalized MD-FEC method, to wireless networks. To protect the encoded scalable video bitstream over a lossy channel and facilitate content adaptation at intermediate nodes, we use product codes based on BCH/CRC codes as row codes and RS codes as column codes. We give a fast algorithm to optimize the product codes within several iterations from a near optimal point. Simulations show good performance in both content adaptation and protection.
