    There is an increasing interest in the deployment of high quality image and video over wireless and IP networks or combination of both. In addition, the heterogeneity of receivers makes it difficult to achieve efficiency and flexibility. Recently, the term video scalability has appeared to solve such problems. Video scalability usually achieved by assigning different quantization bits to the same input video sequence to produce different quality resolutions, or by using up-sampled images from a lower layer as prediction in a higher layer to produce different spatial resolutions. Both methods have limited number of restricted layers. In this paper, a new video layering technique is proposed based on multiplexed wavelet transform. The proposed video layering system has the advantages of high design flexibility and improved bandwidth efficiency through selective choosing the wavelet family to be used at each layer. This can provide combined quality, spatially, and even temporally layered video. The method is proposed to be used for video and colored images.
