A survey on the techniques for the transport of MPEG-4 video over wireless networks

In this paper, we present a survey on the techniques for the transport of MPEG-4 video over wireless networks. As a new object-based video compression standard, MPEG-4 has been proved to be suitable for wireless applications. However, because of the characteristics of wireless channels, such as varying channel capacity and burst bit errors, some new techniques such as scalable and error-resilient video coding techniques are required to be incorporated into MPEG-4 to improve the coding efficiency. These techniques are discussed in this paper. The experimental results show that although these new techniques have improved the performance greatly, there is still a lot of research work to be pursued.
