In the most common form of wavelet video coding, a three-dimensional Discrete Wavelet Transform (DWT) is applied on a group of video frames (GOF). This approach suffers in compression performance because no motion compensation is used. Other approaches to motion compensated wavelet video coding fails to achieve good video quality in packet loss network due to the absence of a resilient transmission method for the motion data. This paper describes a resilient transmission method for the motion parameters. A multiple description (MD) codec is used to encode the video for lossy network. Motion coding and transmission are incorporated in the MD framework. The resulting codec achieves good compression performance in lossless network as well as good resilience in unreliable network. Experimental results also show encouraging performance of the proposed codec compared to state-of-the-art video codec.
