Abstract: An error resilience method for FGS decoder is introduced. Based on this method, a new type of error control method, called bit-plane based error spreading (BES), is proposed. These two methods can effectively improve the decoded image quality of the FGS coded stream over the network with packet losses even bursty errors. The experimental results show that the methods are feasible and effective.
