This paper discusses the scalability of 3D Wavelet Video Coding. Based on the results of recent research, the paper classifies 3D Wavelet Video Coding into diverse groups, and analyzes the compression performance and scalability of them. The paper introduces a promising 3D Wavelet algorithm MC EZBC, and investigate its PSNR\Temporal\Spatial scalability. The paper proposes some ideas to improve the algorithm to be an ideal scalable video codec suitable for video streaming over Internet.
