Arbitrary downsizing video transcoding using H.26L standard

Abstract

Downsizing video transcoding is a useful technique for adapting the bit rate or frame size of a precoded video to suit better the constraints of different transmission networks and receiving devices. To avoid frame skipping and maintain good quality at low bit rates, we have proposed H.263-based video transcoding techniques for downszing a precoded video by an arbitrary factor. In this paper, we extend the proposed techniques by using the newly developed H.26L standard in order to fully exploit the advantages of arbitrary downsizing video transcoding. Experimental results show that the proposed method can achieve much better video quality than that using H.263 standard.
