This paper presents an achievement for full-scalable video coding.A full-scalable video coding system is offered,which is based on the Motion Compensated Temporal Filter(MCTF),Discrete Wavelet Transforms(DWT) and Embedded Zero tree Wavelet (EZW).In this system,adaptive Group of Pictures(GOP) structure is presented for MCTF,and the coded bit-stream is organized to achieve the brilliant combination of three main scalabilities:temporal,spatial and PSNR scalabilities.In the end experimental re-sults show the ceding efficiency of the system.
