Abstract

In this paper we design a multiple description (MD) video coding scheme based on the motion compensated (MC) lifted wavelet transform. A major advantage of basing MD video coding on motion-compensated lifted 3D wavelet decomposition is that it does not require any mismatch control like in a hybrid codec which was previously achieved by sending drift compensation data. We propose to perform the temporal decomposition of a group of pictures and then create multiple descriptions for each temporally transformed frame. We use polyphase sub-sampling with an appropriate amount of oversampling to form the descriptions and to control the redundancy among them. We determine the appropriate amount of redundancy as a function of description loss probability. Our experimental results show that the controlled introduction of redundancy leads to significant improvements in lossy transmission environments.
