Abstract

In this paper, we propose a new trnascoding method for improving picture's visual quality when frames are skipped. the proposed method utilizes the relationships of motion vectors between successive frames, and 4 motion vectors a macroblock are considered in transcoding. Since the proposed method does not require any decoding process of encoded bit stream, the computational complexity for estimating motion vectors can be eliminated. Experimental results illustrated that as transcoded frames are getting far from I pictures and as the degree of motions in video sequences are getting higher, the picture quality by using our proposed method shows better performances than existing schemes.
