Multiple description coding based on multiwavelets transforming

Multiple description coding is a source coding for multiple channels such that a decoder which receives an arbitrary subset of the channels may produce a useful reconstruction, which is one of useful methods for solving the problem of packet losses in network communication. In this paper, on the basis of multiwavelet transform, a new method of multiple description coding will be presented, and experiments show it works well. Moreover, a parametrization of one kind of multifiler banks, which generate multiwavelets with some good properties, will be given.
