Scalable video coding based on MCTF (motion compensated temporal filtering) has been thought of as the important study field for it' s validity of removing temporal correlation. This paper firstly described and analyzed MCTF and its research progress. In addition, adaptive GOP (group of picture) structure selection, improved update operators for lifting-based wavelet and discussed adaptive temporal decomposition level. Finally, pointed out the future development of MCTF.
