When delivering video over communication networks, it is required to transcode the precoded video content to meet the demands of a broad range of end users with different bandwidths and resource constraints. One solution to transmit video over bandwidth-constrained channels is to reduce the spatial resolution of video frames and transmit a low-resolution version of the video as a tradeoff for the bit rate. In this paper, an arbitrary downsizing algorithm is proposed. This arbitrary downsizing algorithm is processed directly in the discrete cosine transform domain. Experimental results show that the proposed method can achieve a satisfactory performance. Compared to the existing methods, this algorithm is not only applicable to an intracoding frame but also to an intercoding frame. This is one of the crucial features of this method.
