Abstract: Scalable video coding (SVC) technology is a new domain in the transaction of picture and video, and there are many products of SVC recently. Motion compensated temporal filter (MCTF) technology is a new research orientation in the video code domain and there are also many products in this field. This paper introduces the main concept of the MCTF and the correlative implementary method and presents a new method of implementing MCTF. The result of experiment indicates that the video images gained by the MCTF have better quality than the video images gained by the traditional MCTF in the same compression radio.

Key words: Scalable video coding (SVC), Motion compensated temporal filter (MCTF), Motion estimation
